Danfoss 068U3750 Hot Gas Bypass Regulator Type TUH

The Danfoss 068U3750 is a Type TUH hot gas bypass regulator engineered to provide precise capacity control in commercial and industrial refrigeration systems. This valve adapts compressor capacity to actual evaporator load by regulating the flow of hot gas from the discharge line to the low-pressure side of the system, preventing evaporator coil freeze-up and maintaining optimal system performance.

Key Specifications:

• Inlet Connection: 3/8 inch ODF solder connection
• Outlet Connection: 1/2 inch ODF solder connection
• Temperature Range: 30°F to 50°F (-1°C to 10°C)
• Orifice Capacity: 2.1 tons refrigeration (7.3 kW)
• Pressure Equalization: Internally equalized
• Compatible Refrigerants: R22, R134a, R407C, R404A, R507, R410A

Features and Benefits:

• Stainless steel hermetically sealed construction for superior corrosion resistance and durability
• Laser-welded diaphragm element ensures long service life and high pressure resistance
• Advanced filter/strainer design protects internal components
• Adjustable setting allows for precise tuning and accurate bypass control
• Low pressure band and minimal hysteresis for consistent regulation
• Compact design facilitates easy installation in existing systems

This hot gas bypass regulator is ideal for applications operating near 0°C evaporating temperature, including air dryers, supermarket refrigeration systems, food processing and storage facilities, commercial cooling systems, and industrial refrigeration applications. The valve effectively prevents excessive pressure buildup while ensuring optimal energy efficiency and reliable system operation.
