The internationally patented process Optimized Refrigerant Supply (ORS) which is incorporated in COOLNOMIX has specific protection included within its function. This includes protection against too frequent stop-start of the compressor and assurance that every re-start is always a soft-start – the re-start of the compressor is never under load since the suction and discharge pressures are guaranteed to be in equilibrium. As a result there is no adverse effect on the operational life of the compressor of the cooling system.
