KryonLube PAG and POE Lubricants for Automotive Air Conditioning

KryonLube PAG and POE lubricants are engineered to meet the specific requirements of vehicle climate control systems, including traditional internal combustion engine (ICE) vehicles and Battery Electric Vehicles (BEVs). These systems utilize refrigerants such as R134a and the more recent R1234yf, which demand lubricating oils with precise properties regarding miscibility, chemical stability, and compatibility with polymeric materials.

Lubrication Technology and Functional Advantages

The range includes PAG (Polyalkylene Glycol) and POE (Polyol Ester) oils specifically tailored for automotive applications. These lubricants are formulated to:

• Maintain high and consistent lubrication performance throughout the operational lifespan of the A/C circuit.
• Offer high resistance to hydrolytic degradation, a critical factor in automotive systems where moisture may be present.
• Ensure compatibility with standard A/C line materials (seals, O-rings, and hoses), reducing the risk of deterioration or damage.
• Guarantee optimized solubility and miscibility with R134a and R1234yf refrigerants, facilitating efficient oil circulation throughout the entire system.
• Ensure compatibility with OEM lubricants, allowing for seamless use during standard maintenance cycles.

While PAG technology is traditionally used in automotive A/C systems due to its thermal stability and ideal viscosity for compressor operation, POE technology is primarily available for electric vehicles (BEVs). In these applications, POE is preferred for its superior electrical insulation properties and compatibility with the sensitive electrical components of the compressor.

Fluorescent Tracer

Select products within the range are enriched with a fluorescent UV dye. This additive allows for the easy detection of small leaks within the A/C circuit using specialized UV lamps during diagnostic analysis. This feature is highly effective for maintenance, repair, and rapid system diagnostics.

These lubricants are fully compatible with the most widely used refrigerants in the automotive sector:

• R134a: Found in many legacy vehicles and still extensively used today.
• R1234yf: A next-generation, low-GWP (Global Warming Potential) refrigerant used in newer vehicles and models to comply with evolving environmental regulations.

Physical-Chemical Properties (Typical)

KryonLube PAG automotive oils are available in various ISO viscosity grades—most commonly ISO 46 and 100. These grades are specifically selected to handle the varying load requirements of A/C compressors and to meet the precise specifications mandated by automotive A/C system manufacturers.

The KryonLube portfolio includes a diverse selection of oil types, viscosities, and packaging formats to meet various maintenance, recharging, and diagnostic requirements:

PAG: For Automotive A/C Systems with R134a and R1234yf

• PAG 46: ISO 46 viscosity, the standard for most automotive A/C compressors.
• PAG 100: ISO 100 viscosity, designed for applications requiring higher viscosity.
• Universal PAG: A specialized formulation compatible with both ISO 46 and ISO 100 systems.

POE: For Specific Applications (e.g., BEVs / Electric Vehicles)

• POE 80 BEV: A POE-based lubricant specifically for electric vehicle compressors.
• POE 100 BEV: A higher viscosity variant for high-performance Battery Electric Vehicles (BEVs).

Additives with Fluorescent Tracer

Select products in the range are pre-mixed with a fluorescent UV dye. This additive facilitates the visual detection of leaks within the A/C circuit when used in conjunction with UV lamps.

Packaging Formats

The line is available in several formats to streamline supply and maintenance operations:

• 250 ml Metal Cans: Ideal for small-scale interventions or top-ups.
• 1 L Metal Cans: The standard format for full-service maintenance on automotive systems.
• Bulk Packs (6 or 12 units of 250 ml or 1 L): Designed for high-volume use in professional workshops and service centers.
