Danfoss claims world’s smallest EEV for small A/C and IT cooling

05 May 2020

Danfoss has unveiled what is claimed to be the world’s smallest electronic expansion valve (EEV), a mini EEV for small A/C and computer room air conditioner (CRAC) units, allowing original equipment manufacturers (OEMs) to drive greater system efficiency, reliability and quieter operations.

Developed in response to market demand for quieter unit operation and greater reliability, the Danfoss ETS 5M is significantly smaller and lighter than the next best alternatives — giving OEMs the opportunity to create Source: DanfossSource: Danfosscompact system designs or replace in existing systems.

For comfort applications, the ETS 5M ensures low acoustic level, and offers full performance bi-flow capability — enabling quiet, precise performance for both cooling and heating.

In addition, the ETS 5M is ideal for high evaporating temperature CRACs with direct expansion. Its precise flow control and best-in-class protection against moisture and internal leakage improves system reliability in data centers where constant temperatures need to be maintained around the clock. The new valve is electrically compatible with existing 12 V drivers. It is a major addition to the portfolio for small A/C units and extends an already well-established portfolio of components for a wide capacity range of CRAC units, which include compressors, controls and sensors, system protectors like filter driers, ball and check valves and micro-plate heat exchangers in WC systems.

While the Danfoss ETS 5M is now available for small A/C units and CRAC applications, Danfoss intends to extend the component’s operating map initially to applications such as heat pumps, and later to semi-plugin cabinet, cold room and refrigerated transport applications.
