The TR design incorporates a hot-pressed brass body with the entire power element, including the capillary tube and bulb, fabricated from stainless steel. These offer high corrosion resistance, high strength and vibration resistance fast installation and good thermal contact and transmission.
All valves are designed with balanced port which reduces the influence from varying condensing pressures.
Laser-welded power element: longer diaphragm life.
High pressure tolerance and working pressure.
The Danfoss TR6 thermostatic expansion valve helps OEMs meet energy challenges by enabling air-conditioning systems to match a cooling demand at any given time. In designs without a TXV, refrigerant flow is regulated by a fixed orifice. Because the size of the orifice remains constant, the flow of refrigerant remains the same regardless of the cooling demand on the system. The result: only average efficiency.
The TR6 design includes a number of features to ensure a long life of efficient service. The sensing bulb charge is carefully optimized for residential air-conditioning. The power element, containing the sensitive valve diaphragm that operates the valve, is laser welded. Because there is much less heat input with laser welding than with traditional plasma welding, the integrity of the diaphragm is not compromised. Danfoss is a pioneer in the use of laser welding, which is also a much cleaner process.
