Danfoss TEAT Series

Danfoss TEAT valves are thermostatic injection valves for ammonia (R717) systems, principally used as desuperheating valves: they inject liquid ammonia into hot discharge gas to control its temperature — for example, cooling compressor discharge gas ahead of oil separators, heat exchangers, or two-stage intercooling duty. The valve is controlled by a thermostatic element responding to the temperature at its sensor location.

The TEAT shares the ammonia parts platform with the TEA family — orifice assemblies are interchangeable across TEAQ / TEA / TEVA / TEAT within a frame size — simplifying stocking and service for industrial ammonia plants.

Types available: Danfoss TEAT 20 for smaller capacities and TEAT 85 for larger capacities, with high-temperature desuperheating elements in the 90 – 130 °C range. Orifice assemblies interchange with TEA, TEVA and TEAQ within the same frame. Send the discharge temperature you are controlling to and the capacity, and we will confirm the frame and orifice.

Fit a TEAT when ammonia discharge gas is running too hot into an oil separator, a heat exchanger or a two-stage intercooler — the classic symptom being oil carbonising or breaking down faster than it should.
