Risk for your compressor
1. Liquid Refrigerant Migration

> Migration of liquid refrigerant to the compressor is a natural occurrence
> The amount and severity of this migration depends on;
> Refrigerant and oil charge
> Length of shutdown interval
> The temperature difference between crankcase oil and the rest of the system.
As the temperature of oil drops, refrigerant is absorbed faster and more completely.
2. Oil Slugging
>When refrigerant has mixed with oil and the compressor starts, oil slugging occurs:
>the mixture foams violently and
>all or most of the oil charge is pumped
>Broken scrolls, valves, damaged pistons and blown head gasket can result.
Solution = Isen cranckcase heater
>By optimising the temperature of crankcase oil, our heater prevents refrigerant migration.
>Oil is kept warmer than the system temperature and refrigerant is forced to
remain in the condenser, evaporator or accumulator.
> Improved performance & reliability ensures efficient & long term protection

The next generation in compressor protection technology.
