Le plus petit détendeur électronique du monde (en anglais)

Danfoss a récemment présenté un petit détendeur électronique, notamment utilisé pour les climatiseurs à débit de frigorigène variable.

Danfoss has unveiled what is believed to be the world’s smallest electronic expansion valve (EEV), a mini EEV for small air conditioners and Computer Room Air Conditioners (CRACs), allowing manufacturers 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 manufacturers the opportunity to create compact 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 valves is electrically compatible with existing 12V drivers. It is a major addition to the portfolio for small air conditioning 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.
