Lennox 93M13 Belt 321142-301 Durable Infrastructure: Heavy-duty materials withstandPreventing liquid refrigerant migration during the off cycle is a critical requirement for maintaining compressor longevity, especially in commercial rooftop units and split systems. The Lennox 93M13 is a heavy duty, belt type crankcase heater designed to maintain optimal oil temperature within the compressor housing. By keeping the lubricant warm, this 70W crankcase heater ensures that refrigerant remains in a vapor state, eliminating the risk of oil
