Crankcase Heaters for HVAC/R Compressors (8400)
The BriskHeat crankcase heater is an industrial-grade electric resistance heater designed to be strapped or clamped securely to the base of a compressor crankcase. It works continuously to keep the compressor oil temperature higher than the coldest part of the system, preventing refrigerant migration and condensation in the oil. These heaters are critical for compressors operating in ambient temperatures lower than the system's operating temperatures. Ideal for both residential and commercial HVAC/R applications, they can be easily retrofitted onto existing systems that lack internal heating elements.
- Flexible Band Style: Form-fitting band design is highly flexible, ensuring maximum surface contact and effortless installation
- Thermal Performance: Delivers rapid heat-up and uniform thermal distribution to keep compressor oil at optimal temperatures
- Rugged Durability: Engineered to be completely moisture-proof and corrosion-resistant for long-term reliability in harsh outdoor environments
- Safety First: Fully grounded construction ensures safe operation and compliance with electrical standards
- Versatile Application: Serves as a high-quality direct OEM replacement or a universal upgrade for aftermarket field installation
