Scroll Crankcase Heater ZRH1

Scroll Crankcase Heater ZRH1 A scroll crankcase heater is a device installed on scroll compressors, a type of compressor commonly used in air conditioning and refrigeration systems. The heater plays a vital role in protecting the compressor during cold weather or extended off cycles. They’re crucial for preventing issues like bearing washout and liquid slugging, especially in colder climates or systems with long shutdowns, ensuring reliable compressor operation They’re crucial for preventing issues like bearing washout and liquid slugging, especially in colder climates or systems with long shutdowns, ensuring reliable compressor operation Prevents Refrigerant Migration: Keeps the crankcase oil warmer than the coldest part of the system, stopping liquid refrigerant from dissolving into the oil. Prevents Oil Foaming: When the compressor starts, the dissolved refrigerant boils off, causing foaming and starving the compressor of lubrication. Ensures Lubrication: By keeping oil and refrigerant separate, it maintains oil viscosity and prevents bearing failure. Protects Scroll Compressors: While scrolls are robust, heaters prevent catastrophic failure from liquid refrigerant, especially in heat pump applications.  Works on Copeland scroll compressor crankcase heater Panasonic scroll compressor Crankcase heater Invotech scroll compressor crankcase heater  Crank case heater  For a full range of scroll compressor  SKU: ZRH1 Categories: Cold room/Freezer room accessories, Fridge/Cold room accessories
