Permanent Ceramic Protection for A/C & Refrigeration Compressors

Cerma Blue Ice A/C & Refrigeration Ceramic Treatment is a one-time application that permanently bonds STM-3® Nano Silicon Carbide (SiC) ceramic to the internal metal surfaces of any A/C or refrigeration compressor. Works on automotive A/C, residential HVAC, commercial rooftop units, walk-in refrigeration, industrial chillers, data center cooling, and marine A/C. Compatible with every common refrigerant including the new low-GWP generation (R-1234yf, R-454B, R-32) and all legacy refrigerants (R-410A, R-134a, R-22, R-404A, R-407C, R-507).

Five sizes match system scale from a single car A/C (1 oz) to large industrial chillers (128 oz). Made in the USA by Bijou Inc. in Fort Myers, FL. One-time application — no reapplication at future service or recharge. Requires the reusable Cerma Applicator Tool (sold separately) for injection through the low-side service port.

❄ Why Blue Ice is different: Conventional A/C additives are oil-based lubricants that circulate with the refrigerant and gradually deplete. Cerma Blue Ice uses Nano Silicon Carbide to permanently bond a ceramic layer to the compressor's internal metal surfaces — creating a durable, low-friction coating that doesn't wash out during future service or refrigerant recharges. One application; the protection stays bonded to the compressor for the life of the unit.
⚠ Applicator Tool Required for Installation: Cerma Blue Ice is injected into the refrigerant circuit through the low-side service port — this requires the Cerma Applicator Tool, which is sold separately. The applicator is a one-time purchase and reusable across any system and any future Cerma Blue Ice application. If you are a DIY customer without EPA Section 608 certification, note that working with refrigerant on R-134a, R-1234yf, R-410A, R-454B, or R-32 systems generally requires certification in the US for legal refrigerant handling — have a certified HVAC technician or auto A/C shop perform the application if you don't hold certification. First-time customers ordering for automotive A/C commonly add the applicator tool to their first order.

What Cerma Blue Ice Does

  • Helps improve A/C cooling efficiency — reduced friction and optimized heat transfer at compressor internals can result in colder output temperatures from the same equipment at the same refrigerant charge.
  • Reduces energy consumption* — less compressor load means lower electric bills on residential and commercial HVAC, and reduced engine load on automotive A/C (which translates to small fuel economy improvements on long hot-weather drives with A/C at max).
  • Shortens compressor cycle times — when the system reaches target temperature faster, the compressor runs fewer cycles per hour, reducing wear on start-stop components.
  • Improves heat transfer at metal surfaces — SiC ceramic improves contact between compressor internals and refrigerant, which directly affects how efficiently heat moves through the system.
  • Reduces internal moisture and acid buildup — helps protect against the corrosion and acid formation that cause compressor failure over time, especially in older systems with marginal filter-drier condition.
  • Quieter compressor operation — reduced friction reduces compressor vibration and operating noise, noticeable on window units, mini-splits, and older central A/C units where compressor noise has been worsening.
  • Helps revive hard-start units* — customers report that marginal compressors which struggle to start or short-cycle under load have regained reliable operation after Blue Ice application, by reducing the internal friction that contributes to hard-start conditions.
  • May reduce the need for Saturated Air Dryer Module replacement — common failure pattern on certain commercial systems where premature dryer saturation leads to costly replacement recommendations.
  • Helps extend compressor life — permanent ceramic protection reduces wear progression on scrolls, pistons, bearings, and valve plates — the parts that define when a compressor reaches end of service life.
💡 Why compressor wear matters: Compressors fail from three primary causes: insufficient lubrication at startup (when oil film is thinnest), accumulated wear on close-tolerance internal surfaces, and moisture or acid attack from refrigerant degradation. Cerma Blue Ice addresses all three — the SiC ceramic layer lubricates during startup before conventional oil reaches full coverage, it reduces ongoing wear on compressor internals, and it helps resist the moisture and acid that shorten compressor life. A compressor that normally sees 10–15 years of service can often exceed those expectations with ceramic protection applied early.

Cerma Blue Ice bonds to compressor metal, not refrigerant — so refrigerant chemistry doesn't affect ceramic performance. Compatible with systems using PAG oil, POE oil, mineral oil, and AB (alkylbenzene) lubricants.

📋 How to Apply

  1. Determine the correct dosage for your system (see Dosage Guide below). For residential HVAC, this is roughly 1 oz per ton of cooling capacity; nameplate on outdoor condenser unit shows tonnage, or divide BTU rating by 12,000.
  2. Verify you have the Cerma Applicator Tool. First-time customers need to add this to their order — it's sold separately and is reusable across any future Blue Ice application on any system.
  3. Connect the applicator tool to the system's low-pressure service port (the blue port on residential systems; the thicker suction line on automotive A/C).
  4. Run the system briefly to bring pressures to normal operating range, then inject the correct dose of Cerma Blue Ice through the applicator.
  5. Operate the system normally — the SiC ceramic particles bond to compressor internals during normal refrigerant circulation over the first several hours of runtime.
  6. Permanent protection — no reapplication. Future refrigerant service, charge adjustments, or even full recovery and recharge do not affect the ceramic bond on compressor metal.

📐 Dosage Guide — How Much Do I Need?

System Type Dosage
Automotive A/C (cars, trucks, SUVs, vans, class 1–6 trucks) 1 oz per system
Class 7/8 semi truck A/C 2 oz per system
Residential A/C (central, heat pump, mini-split) 1 oz per ton of cooling capacity (typical home 2–5 tons → 2–5 oz)
Residential window unit or portable A/C (under 1 ton) 1 oz total
Commercial HVAC (rooftop, split, package unit) 1 oz per ton of cooling capacity
Commercial refrigeration (walk-ins, display cases, ice machines) 1 oz per ton of refrigeration capacity; small systems often 1 oz total
Large chillers and industrial cooling 1 oz per ton — call 239-344-9861 for sizing guidance on 50+ ton systems
🏠 Quick tonnage check for residential HVAC: Look at the outdoor condenser unit's nameplate — tonnage is listed directly, or calculate from the BTU rating (BTU ÷ 12,000 = tons). Rough size-to-tonnage: 1,200 sq ft home ≈ 2 tons (2 oz); 1,800 sq ft ≈ 3 tons (3 oz); 2,400 sq ft ≈ 4 tons (4 oz); 3,000 sq ft ≈ 5 tons (5 oz). Exact tonnage varies by climate zone, insulation, and ceiling height. When in doubt, round up — slight over-dose is not harmful. Not sure? Call 239-344-9861 with your outdoor unit's model number and we'll look up tonnage.

The Science — Silicon Carbide (SiC) in A/C Compressors

A/C compressors are high-speed, high-friction mechanical devices with tight internal tolerances. Scroll compressors (most residential HVAC) run with orbiting scrolls separated by micron-scale clearances; reciprocating compressors (many commercial units and older residential) have piston-to-cylinder sealing surfaces; rotary compressors (mini-splits) have rolling-piston sealing surfaces; centrifugal compressors (large chillers) have high-speed impeller interfaces; screw compressors (industrial) have interlocking rotors. All of these designs have metal-to-metal contact points where friction and wear degrade efficiency over the unit's service life.

Cerma STM-3 Nano Silicon Carbide — Mohs hardness 9.5, melting point 2,730°C — bonds a ceramic matrix to compressor metal at the sub-surface level. The resulting hard, low-friction layer:

  • Reduces the friction coefficient at compressor contact points, which reduces the energy needed to compress refrigerant
  • Improves heat transfer at metal-to-refrigerant contact surfaces by smoothing microscopic surface roughness
  • Creates a self-lubricating protective layer that provides protection during compressor startup — the critical moment when conventional oil coverage is lowest and most wear occurs
  • Helps prevent the progressive wear that gradually erodes compressor efficiency across years of service

Because the bond is chemical and permanent, future refrigerant recharges, oil changes, filter-drier replacements, and other routine A/C service do not affect the ceramic protection. The ceramic layer remains bonded to compressor metal regardless of what refrigerant or oil circulates through the system afterward.

Cerma Blue Ice vs. Conventional A/C Additives

Feature Cerma Blue Ice Conventional A/C Additives
Technology Nano Silicon Carbide ceramic PAG/POE oil supplements, UV dye, sealants
Mechanism Bonds ceramic to compressor metal Circulates with refrigerant
Application ✓ One-time (permanent) ✗ Needs reapplication over time
Survives Refrigerant Recharge ✓ Yes — bonded to metal ✗ Recovered out with old refrigerant
Reduces Energy Use* ✓ Measurable ⚠ Minimal
Helps Revive Hard-Start Units ✓ Customer-reported yes ✗ No
Refrigerant Compatibility ✓ All (R-410A, R-134a, R-1234yf, R-454B, R-32, R-22, etc.) ⚠ Often refrigerant-specific
Sealant Properties ✗ Not a sealer ⚠ Stop-leak products risk clogging orifice tubes and expansion valves

Important distinction: Cerma Blue Ice is not a stop-leak or sealant product. Stop-leak products (sometimes sold as "A/C leak sealer") can clog orifice tubes, TXVs, and condenser microchannels — a common cause of warranty disputes and repair failures. Blue Ice is a ceramic wear-protection treatment that works on compressor internals only; it does not seal leaks and does not deposit anything in refrigerant lines.

Frequently Asked Questions

Yes — Cerma Blue Ice is compatible with all current and emerging low-GWP (global warming potential) refrigerants. R-1234yf became the mandatory refrigerant in all US-sold new vehicles starting 2017, replacing R-134a. Every major automaker — Ford, GM, Stellantis (Chrysler/Dodge/Ram/Jeep), Toyota, Honda, BMW, Mercedes, VW/Audi, Hyundai/Kia, Subaru, Mazda, Nissan — uses R-1234yf on new vehicles. R-454B is the new residential HVAC standard starting January 1, 2025 under the EPA AIM Act, replacing R-410A on new installations. Carrier, Trane, Lennox, Rheem, Goodman, York, Bryant, and American Standard have all transitioned to R-454B (or the alternative R-32). R-32 is widely used in mini-split systems from Mitsubishi, Daikin, Fujitsu, LG, and Samsung. Cerma Blue Ice works across all of these because the SiC particles bond to the compressor's metal — they don't interact with refrigerant chemistry. If your system was installed or serviced with any of these refrigerants, Blue Ice protects the compressor regardless.

Yes. Although R-22 (HCFC) was phased out of US production in 2020 under the Montreal Protocol, millions of R-22 residential A/C systems are still in service because existing systems can continue to be recharged from recycled R-22 stock. If you have an older central A/C system (typically pre-2010 installation), there's a good chance it's still running R-22. Cerma Blue Ice works on R-22 systems and is actually a smart investment for aging R-22 systems specifically: the compressor is often the most expensive-to-replace component, R-22 itself has become expensive due to supply constraints, and extending compressor life on an existing R-22 system delays the capital cost of a full system replacement. One Blue Ice application can add years of reliable service to an R-22 compressor that might otherwise need replacement within 1–3 years.

Yes — Cerma Blue Ice works in all automotive A/C systems. One 1-oz dose per passenger vehicle (cars, trucks, SUVs, vans); 2 oz for class 7/8 semi truck A/C (which has larger-displacement compressors). Compatible with all major automotive A/C compressor manufacturers: Sanden (widely used across Ford, Honda, Toyota, and many Asian brands), Denso (Toyota, Lexus, Honda, GM, Ford, and OEM across many Asian and European brands), Delphi/Mahle (GM, Ford, Chrysler, many European vehicles), Valeo (European and some American vehicles), TRSA, Seltec, Calsonic, and the integrated compressors on many hybrid and electric vehicles (where the A/C compressor is electrically driven rather than belt-driven). Works with both PAG (polyalkylene glycol) oil on R-134a and R-1234yf systems, and any legacy mineral or POE oils.

Often yes for residential and commercial HVAC, but the exact savings depend heavily on your starting baseline. Customers most likely to report noticeable savings: (1) older HVAC systems (10+ years) where compressor efficiency has degraded from wear — these have the most to gain from ceramic restoration; (2) systems in hot climates with long cooling seasons where A/C energy is a large share of total electric use; (3) properties with poor insulation or ductwork issues where the HVAC runs longer per day. Customers less likely to see dramatic savings: newer high-efficiency heat pumps already operating near their design SEER, systems in moderate climates with short cooling seasons, or well-insulated homes with small HVAC loads. The mechanism is real (reduced compressor friction = reduced electric demand during compressor operation) but the percentage savings vary from minimal to substantial based on system condition. For HVAC contractors: Blue Ice is especially valuable on customer complaint calls where "the A/C isn't as cold as it used to be" is a symptom of compressor wear rather than low refrigerant.

Customers have reported this outcome. Hard-start and short-cycling conditions on marginal compressors often trace to accumulated internal friction — the compressor motor has to overcome more drag at startup than it was designed for, which trips the thermal overload or hard-start capacitor. Cerma Blue Ice reduces that internal friction via the ceramic layer, which in many customer reports has restored reliable starting behavior on compressors that were on the edge of replacement. Honest limitations: if your compressor has actual mechanical failure (seized bearings, broken internal valves, burnt motor windings, dead start capacitor, or grounded compressor), Blue Ice cannot fix those — they require mechanical replacement of the failed part or full compressor replacement. The treatment is wear-protection and friction-reduction, not a repair product. Before purchase on a hard-start unit, call 239-344-9861 — we can help assess whether your symptoms match conditions where Blue Ice has helped, or whether you're facing something that needs a repair call instead.

No — and this is important. Cerma Blue Ice is not a stop-leak or sealant product. It's a ceramic wear-protection treatment that bonds to compressor metal and does not deposit material in refrigerant lines, orifice tubes, expansion valves, or condenser microchannels. If your A/C system has a refrigerant leak, address it as a mechanical problem: find the leak (UV dye tracer, electronic leak detector, or pressure-decay test), repair it (replace the leaking component, hose, fitting, or seal), then recharge to spec. Only after the leak is fixed should you apply Blue Ice. We specifically avoid stop-leak functionality because "A/C leak sealer" products sold at auto parts stores are known to cause expensive damage — they can clog orifice tubes and TXVs, contaminate recovery machines at future service, and void warranty coverage at some dealers. Blue Ice protects the compressor; repair fixes the leak. Two different jobs.

One-time. The SiC ceramic bonds permanently to the compressor's internal metal surfaces through a thermo-chemical reaction driven by normal operating conditions inside the refrigerant circuit. Once cured, the ceramic matrix is part of the metal, not a film circulating in the refrigerant or oil. This means: (1) future refrigerant recharges do not remove the ceramic layer — even if the entire refrigerant charge is recovered and replaced, the ceramic stays bonded to compressor metal. (2) Filter-drier changes or oil changes during service do not affect the ceramic protection. (3) A system drained and recharged during coil replacement or major service still has Blue Ice protection on the original compressor. (4) If the compressor itself is ever replaced, the new compressor needs its own Blue Ice application to receive the ceramic protection — the bond is on the metal that's in the system now, not a system-wide treatment that migrates to replacement parts.

Yes. Cerma Blue Ice works on all commercial refrigeration equipment — walk-in coolers, walk-in freezers, reach-in coolers/freezers, supermarket display cases, blast chillers, ice machines, soft-serve machines, beverage coolers, cold storage warehouses. Dose at 1 oz per ton of refrigeration capacity (a typical walk-in cooler at a restaurant runs 1–3 tons; a small walk-in freezer 2–5 tons; supermarket cases vary widely; cold storage warehouses can be 50–500+ tons). Compatible with all commercial compressor designs: scroll (Copeland ZR/ZB/ZS series, Emerson scrolls), reciprocating (Copeland semi-hermetic K/L/M/N series, Tecumseh reciprocating), rotary, screw (Bitzer CSH, Copeland semi-hermetic screw), centrifugal (larger chillers). Compatible with all refrigeration refrigerants including R-404A, R-407C, R-507, and the newer R-448A / R-449A / R-454A low-GWP replacements being deployed under the EPA AIM Act commercial-refrigeration phase-down.

Cerma Blue Ice delivers a connected set of benefits from one mechanism — reduced friction and improved heat transfer at compressor internal surfaces. (1) Improved cooling efficiency — colder output air from the same equipment at the same refrigerant charge. (2) Reduced energy consumption (customer-reported, system-dependent) — lower electric bills on residential and commercial HVAC, reduced engine load on automotive A/C. (3) Shortened compressor cycle times — systems reach target temperature faster and run fewer cycles per hour. (4) Improved heat transfer at compressor-to-refrigerant contact surfaces. (5) Reduced internal moisture and acid buildup — helps protect against the corrosion mechanisms that shorten compressor life over years of service. (6) Quieter compressor operation — reduced friction reduces noise and vibration, noticeable on window units, mini-splits, and older central A/C. (7) Hard-start assistance (customer-reported) — marginal compressors that struggle to start or short-cycle often regain reliable operation. (8) Saturated Air Dryer Module support — may reduce the need for costly dryer replacement on certain commercial systems. (9) Extended compressor life — permanent ceramic protection reduces wear progression on scrolls, pistons, bearings, and valve plates. (10) Universal refrigerant compatibility — works with R-1234yf, R-454B, R-32, R-410A, R-134a, R-22, R-404A, R-407C, R-507, and the newer low-GWP blends R-448A/R-449A/R-454A.

Yes. Cerma Blue Ice is injected into the refrigerant circuit through the system's low-pressure service port — this requires the Cerma Applicator Tool, which is sold separately. First-time customers commonly add the applicator tool to their initial order. It's a one-time purchase — the tool is reusable across any A/C or refrigeration system and any future Cerma Blue Ice application you perform. The tool connects to the low-side service port (the blue-capped fitting on residential HVAC systems; the thicker suction-line fitting on automotive A/C) and allows controlled injection of the ceramic treatment into the running refrigerant circuit. Important regulatory note for DIY customers: in the US, working with refrigerant on systems containing R-22, R-410A, R-134a, R-1234yf, R-454B, and other controlled refrigerants generally requires EPA certification — Section 608 for residential and commercial HVAC, Section 609 for motor vehicle A/C. If you don't hold the appropriate certification, have a certified HVAC technician or auto A/C service shop perform the Blue Ice application for you. Many HVAC contractors and A/C shops are familiar with Cerma products and will perform the application as part of a service call at reasonable cost.

Cerma Blue Ice works on virtually every A/C and refrigeration system that uses a refrigerant and a compressor. Automotive A/C — cars, trucks, SUVs, vans, and class 7/8 semi trucks across every major automotive compressor brand (Sanden, Denso, Delphi/Mahle, Valeo, TRSA, Seltec, Calsonic). Residential HVAC — central air, heat pumps, mini-splits, window units, portable A/C from Carrier, Trane, Lennox, Rheem, Goodman, York, Bryant, American Standard, Daikin, Mitsubishi Electric, Fujitsu, LG, Samsung, and all major brands.
