TCAE Element for Thermostatic Expansion Valve
Brand: DanfossThe TCAE is made of stainless steel and therefore is especially well-suited to refrigeration systems where aggressive environments exist.
The TCAE has been developed and designed especially for soldering into hermetic refrigeration systems.
The valves are offered in rated capacities up to 4.8 TR R407C (TU) / 7.5 TR R407C (TC).
Features- Interchangeable orifice assembly - For easier stocking, capacity matching and service
- Bi-Metal connections - Fast and easy soldering without the need for a wet cloth
- Refrigerants R22, R134a, R404A, R407A, R407C, R407F, R507, R410A (for other refrigerants, contact Danfoss)
- Compact design - Small dimensions and light weight for compact installation
- Stainless steel - High body strength, high corrosion resistance, highly vibration-resistant, flexible capillary tube
- Laser-welded power element insures diaphragm´s structural integrity and lengthens life
- Stainless steel capillary tube - Tolerates more bending for easier installation and longer life, greater resistance to vibration during operation
- Stainless steel bulb - Self-aligning for fast and easy installation; secures with a single strap or quick clip, more contact surface for better heat transfer
- Laser engraving - Durable positive valve identification; no labels to peel off over time
