Danfoss launches enhanced and new electric expansion valves for CO2
The upgraded valve handles 49 bar MWP and 42 bar MOPD bi-directionally across a temperature range of -40 °C to 80 °C, offering corrosion and vibration resistance for harsh environments.

The ETS 5T is the latest step in Danfoss’ ongoing efforts to support the refrigerant transition and provide HVAC&R professionals with the widest possible choice when designing CO2-based refrigeration systems.
"CO2 refrigeration systems have been our focus for over 15 years. During that time, we’ve seen how food retailers have embraced this natural refrigerant as an attractive alternative to HFCs, with as many as 10,000 supermarkets switching to CO2 refrigeration systems each year. And with this newest addition to our electric expansion valve portfolio, we support an even wider range of CO2 systems, from the small, transportation units to large, transcritical installations," said Mark Sever, Global Solutions Expert at Danfoss Climate Solutions.
A compact valve with a wide range of applications
The ETS 5T features the same compact design as Danfoss’ ETS 5M, which is the smallest electronic expansion valve (EEV) on the market. The 5T version is designed for CO2 applications from 4 to 19 kW, has a maximum working pressure (MWP) of 140 bar and a maximum operating pressure differential (MOPD) of 120 bar for transcritical CO2 systems. It supports a refrigerant temperature range from -40 to 80 degrees Celsius and an ambient temperature range of -40 to 80 degrees Celsius. The ETS 5T also supports bi-directional flow, operating at full performance in normal and reverse flow directions.
Upgraded ETS 5M well-suited for smaller capacity applications
Danfoss has also made enhancements to its existing ETS 5M valve, giving HVAC&R professionals more flexibility when designing systems. The upgraded valve supports a Max Working Pressure (MWP) of up to 49 bar, an MOPD of up to 42 bar, in both flow directions, and a temperature range of -40 to 80 degrees Celsius. It’s also corrosion and vibration resistant which makes it suitable for harsh environments. With its compact form and wide range of orifice sizes, the upgraded ETS 5M can work even with smaller systems.
Ensuring reliability and low applied costs
Common for both valves was Danfoss’ desire to create a reliable, versatile valve that customers could install quickly and easily.
Supporting HVAC&R professionals in the refrigerant transition
According to Mark Sever, these additions to Danfoss’ electric expansion valve portfolio, together with the rest of Danfoss broad portfolio of filter dyers, shutoff ball valves, regulating and solenoid valves, valve drivers, controllers, compressors, drives and other applications related Danfoss products, demonstrate the company’s continued commitment to supporting the refrigeration industry in the transition to low-GWP refrigerants.
