Built on a foundation of precise superheat control, the Danfoss TD1 thermostatic expansion valve now features a more sustainable stainless-steel capillary tube and sensing bulb.

The TD1 delivers up to 15 per cent more energy savings and up to 20 per cent reduction in pull-down time under actual operating conditions compared to capillary tubes.

Known for its high efficiency and quality, the TD1 thermostatic expansion valve is engineered to control liquid injection into small capacity evaporators for commercial refrigeration applications such as glass door merchandisers, commercial fridges and freezers, walk-in cold rooms, ice machines, ice cream cabinets, and refrigerated beverage dispensers.

The TD1 range now features a capillary tube and sensing bulb both made of stainless steel—which will be standard across all Danfoss TXVs with UL approval as of March 2022. In addition to being a more sustainable material than copper, stainless steel is also more adaptable to varying temperatures.

Compared with standard capillary tubes, thermostatic expansion valves have a huge advantage: namely, the ability to adapt to varying cooling conditions for efficient superheat control.
