Danfoss 067N8306 7/8″ ODF Hot Gas Bypass Regulator

The Danfoss 067N8306 is a hot gas bypass regulator engineered to maintain stable system operation during low-load or no-load conditions in commercial and industrial refrigeration and air conditioning systems. By diverting hot discharge gas back to the evaporator inlet, this regulator prevents evaporator freeze-up, compressor short-cycling, and pressure instability — protecting system components and extending equipment life.

Product Overview

Hot gas bypass regulators are a critical component in systems where the cooling load can drop significantly below the compressor’s minimum capacity. The Danfoss 067N8306 maintains a minimum evaporating pressure by introducing controlled amounts of hot discharge gas into the low-pressure side of the system, ensuring continuous, stable compressor operation regardless of load fluctuations.
