Danfoss T 2 Thermostatic Expansion Valve | R22 / R407C | Internal Equalization | 068Z3281
Product Description:
The Danfoss T 2 (068Z3281) is the go-to choice for technicians in the UAE seeking a simplified and efficient expansion solution for small refrigeration and air conditioning units. As an “Internal Equalization” model, it eliminates the need for an external pressure line, making it easier and faster to install in compact cabinets or split AC units. This valve is dual-rated for both R22 and R407C, providing high flexibility for maintenance and retrofit projects across Dubai. Its modular design with an interchangeable orifice ensures that you can precisely match the cooling capacity to the evaporator’s needs, while the stainless steel power element guarantees a long, leak-free service life even in the high-ambient conditions of the Middle East.
Key Features & Benefits:
- Internal Equalization: Simplifies installation by removing the requirement for an external equalization connection, ideal for smaller UAE cooling systems.
- Dual-Refrigerant Compatibility: Optimized for both R22 and R407C, making it a versatile spare part for various AC and refrigeration brands.
- Modular Orifice System: Allows for easy cleaning and capacity adjustment by simply swapping the orifice assembly (sold separately).
- Robust Stainless Steel Build: Features a laser-welded power element for maximum durability against vibrations and thermal stress.
- Stable Superheat Control: Protects the compressor from liquid slugging while maximizing the cooling performance in Dubai’s heat.
