In a refrigerated compressed air dryer, maintaining a stable Pressure Dew Point (PDP) is critical to ensuring high-quality compressed air, preventing moisture condensation within the piping system, and protecting downstream pneumatic equipment.
To achieve this, two essential refrigeration control valves are widely used:
These pressure-regulating valves play a vital role in maintaining refrigeration system stability, protecting the compressor, and ensuring the refrigerated air dryer consistently delivers a pressure dew point between 3°C and 7°C, which is the industry standard for most industrial compressed air systems.

The ADR Series Hot Gas Bypass Valves, including models ADRIE-1-1/4, ADRSE-2, ADRPE-3, and ADRHE-6, are designed to regulate and maintain stable suction pressure in refrigeration systems and refrigerated compressed air dryers.
When the thermal load decreases, the valve automatically bypasses a portion of the hot discharge gas to the low-pressure side of the refrigeration circuit. This prevents the suction pressure from dropping too low, reduces the risk of evaporator freeze-up, and protects the refrigeration compressor.
The valves are compatible with various refrigerants, including R22, R134a, R404A, R407C, and R401A. They are suitable for systems requiring stable operation, precise dew point temperature control, and high reliability.
