Danfoss Hot Gas Bypass Regulator | TUH | 068U2969
Product Description: The TUH regulator (068U2969) is an essential component for system capacity control. In the UAE, where cooling loads can fluctuate significantly between the peak heat of the afternoon and cooler nights, the TUH acts to bypass hot gas from the high-pressure side to the low-pressure side. This prevents the evaporator pressure from falling below a preset limit, protecting the compressor from “short-cycling” and preventing evaporator icing. Built with a robust stainless steel body and bi-metal connections for easy soldering, this regulator is ideal for commercial refrigeration and air conditioning systems in Dubai and Abu Dhabi that require precise and reliable performance.
Key Features & Benefits:
- Superior Capacity Control: Ensures stable operation even when the cooling demand is low, a critical factor for UAE commercial systems.
- Stainless Steel Construction: Provides exceptional resistance to corrosion, essential for the high-humidity and saline environments of coastal UAE cities.
- Bi-metal Connections: Allows for quick, safe, and stress-free soldering during installation or maintenance in Dubai.
- Compressor Protection: Extends the life of the compressor by reducing frequent on/off cycles during periods of reduced load.
- Compact Design: The lightweight and small footprint allows for easy integration into existing UAE refrigeration racks and units.

FAQs:
- Q: Why is a hot gas bypass regulator like the 068U2969 used in Dubai?
- A: It is used to balance the compressor capacity with the actual evaporator load, preventing the system from freezing up when the cooling demand drops in UAE buildings.
- Q: Does the TUH 068U2969 require external equalization?
- A: Most TUH models are designed to sense the pressure at the outlet/suction line to regulate flow accurately.
- Q: Is this model compatible with R410A in the UAE?
- A: The TUH series is compatible with most HFC/HCFC refrigerants. However, always check the specific pressure ratings (Max 34 bar) against your UAE system’s requirements.
