Danfoss Releases New Electric Expansion Valves Range, ETS 8M Series For Enhanced Efficiency In Heat Pumps And IT Cooling

Danfoss has announced further additions to its ETS range of electric expansion valves for heat pumps, close controls, and process chillers. The ETS 8M enables OEMs and end-users to benefit from greater efficiency and reliability, with low applied costs.

New ETS 8M series

To further strengthen and expand the choice available to OEMs, the new ETS 8M series offers additional options in the lower capacity end of the Danfoss EEV portfolio. With 4 sizes available from 12 to 40 HP (62 to 114 kW) with high bi-flow MOPD, application costs can be significantly reduced, by only using one valve in both flow directions.

The valves have been designed to deliver high accuracy, performance, and energy efficiency, and are ideal for use in applications, where round-the-clock temperature consistency is critical.

Key features include:

• Low Opening Degree (DO) and Stable Control
• High MOPD in normal and reverse flow
• Linear stable flow control
• Dedicated L and S flow curves for modular chillers and low ambient HPs, respectively

Supports shift towards low-GWP refrigerants

Danfoss has drawn on its expertise and experience to support customers, with the shift towards low-GWP refrigerants

Danfoss has drawn on its expertise and experience to support customers, with the shift towards low-GWP refrigerants. The ETS 8M series is compatible with R454B, as well as R32 refrigerants and can be complemented with an entire portfolio of Danfoss components, compressors and heat exchangers available with these refrigerants, including more low-GWP options. They are also compatible with existing 12V drivers.

Victor Marinich, Danfoss’ Global Marketing Director for Air Conditioning, said “Our ETS 5M valves have already shown the high levels of performance and efficiency possible in compact systems. They’ve been growing in popularity in the heat pump market and we will continue to broaden this development program.”

multiple advantages to system designers

Victor Marinich adds, “When developing ETS 8M, our goal was to develop a valve that brought significant advantages to system designers. With the ETS 8M range, we are closing the gap in capacity between the small, efficient ETS 5M and the innovative, fast-closing ETS Colibri.

He further said, “In our Advanced Development Center, the Danfoss ETS 8M achieved better performance, in terms of system efficiency and control stability versus the most common solutions available today.”
