For Hydrocarbon refrigerant (e.g. R600a)

ZEROL AB 5T is based upon alkylbenzene technology and ZEROL ESTER 4 is a polyol ester. Both premium products are designed specifically for R600a systems. They both exhibit low viscosities, formulated to ensure maximum hydrodynamic and boundary lubrication within the exacting tolerances of HC compressor design. They demonstrate excellent miscibility with R600a across the required wide temperature range and offer excellent system component compatibility.
