Reliable Danfoss TES2 Thermostatic Expansion Valve Valve R404A / R507A for Precise Refrigerant Control

The Danfoss TES2 thermostatic expansion Valve R404A / R507A is designed for precise regulation of refrigerant liquid injection into evaporators, making it ideal for use with R404A and R507A refrigerants in commercial and industrial refrigeration systems.

Features and Benefits:

• Connection Type: 3/8″ flare inlet × 1/2″ flare outlet
• Pressure Equalization: Externally equalized to handle pressure drops in evaporator outlet tubes, improving system stability.
• Operating Temperature Range: Suited for temperatures from -40°C to +10°C.
• Adjustable Superheat: Allows fine-tuning of refrigerant flow for optimal cooling efficiency and system protection.
• Durable Design: Brass body ensures durability and corrosion resistance in demanding applications.
• Capillary Tube: 1500 mm length for flexible sensor placement.
• Broad Applications: Widely used in supermarket refrigeration, cold storage, food processing, and HVAC systems.

Operational Overview of Valve R404A / R507A:
The TES2 valve operates based on the refrigerant superheat, ensuring that the evaporator receives the correct amount of refrigerant corresponding to the cooling load. The external pressure equalizer compensates for pressure drops in the evaporator outlet line, which prevents flooding or starving in the evaporator coils and protects the compressor.

Additional Advantages:

• Energy efficient, reducing compressor workload
• Easy to install and maintain with standard flare fittings
• Compatible with a range of operating pressures and refrigerants
