ZEROL® AB Series

Shrieve is at the forefront of lubrication technology formulating synthetic alkyl benzene based lubricant solutions for the latest generation hydrocarbon refrigerants.

Our foundation within specialty lubricants was established with the supply and marketing of ZEROL AB lubricants formulated for stationary refrigeration systems using traditional CFC (e.g. R12) and HCFC (e.g. R22) refrigerants.

Their very low pour point, anti-foaming properties and good stability at high temperature provides optimum lubrication even under the most severe conditions.

Shrieve also run development programmes with OEMs to formulate lubricant solutions for specific compressor and system designs. Please contact us for further information.

ZEROL® AB

The ZEROL AB range is typically available in the following viscosity grades, with regional variations:

Viscosity Grade (VG): 32; 40; 46; 55; 68; 74; 100

Please check with your regional Shrieve office for availability and/or recommended grades. The instructions from the compressor manufacturer must always be followed.

ZEROL® 350

ZEROL 350 is used in systems employing R717 (ammonia) as a refrigerant and has been extensively OEM approved in this application. Compared to traditional mineral oil based technology, ZEROL ABs often demonstrate higher thermal stability and lower volatility, extending lubricant lifetime and reducing downtime and maintenance costs.

Instructions from the compressor manufacturer must always be followed.

These natural refrigerants, which include R290 (propane), R600 (n-butane), and R600a (iso-butane) require lubricants formulated to ensure maximum hydrodynamic and boundary lubrication within the exacting tolerances of HC compressor design. Shrieve has developed specific lubricant technologies, including very low viscosity ZEROL AB options for R600a to meet these specific demands, as well as providing excellent system component compatibility.

ZEROL® RL 5S

A premium alkyl benzene based low viscosity (VG 5) refrigeration compressor lubricant developed for R600a refrigerant systems. ZEROL RL 5S has excellent miscibility with R600a and other HC refrigerants, together with good stability, anti-foaming properties and excellent lubrication performance under severe operating conditions.

ZEROL® RL 5M

A low viscosity mineral based lubricant formulated specifically to provide optimised energy efficiency whilst ensuring maximum product lifetime for R600a refrigeration systems.

Instructions from the compressor manufacturer must always be followed.
