DENMARK: Danfoss has introduced what it claims is the first thermostatic expansion valve for use with CO2 refrigerant.

This new solution is based on Danfoss’ established TE2 valve, which is well-known for its accurate and reliable superheat control, easy installation, and good temperature transfer due to their interchangeable orifice assembly and stainless-steel bulb.

Now qualified for CO2, the TE2 features a stainless steel capillary tube and bulb. It is said to be suitable for small to medium size remote refrigeration systems such as cold rooms and display cabinets as used in convenience stores, restaurants, and small supermarkets.
