Description
The Danfoss 068U3748 is a hot gas bypass regulator engineered for R-134A refrigeration and air conditioning systems. Designed to maintain stable evaporator pressure and prevent coil freeze-up during light-load or part-load operating conditions, this regulator diverts hot discharge gas directly into the low-pressure side of the system — allowing the compressor to run continuously while delivering precise capacity control without short-cycling.
Product Overview
Hot gas bypass regulators are a proven solution for maintaining minimum system load in commercial refrigeration and HVAC applications. The Danfoss 068U3748 is sized for R-134A service with 3/8″ inlet and 1/2″ outlet connections, making it a reliable fit for a wide range of light commercial and commercial refrigeration equipment.
