DENMARK: Danfoss has unveiled what it believes is the world’s smallest electronic expansion valve for small air conditioners with greater system efficiency, reliability and quieter operations benefits for OEMs.
The Danfoss ETS 5M is said to be significantly smaller and lighter than the next best alternatives, giving OEMs the opportunity to create compact system designs or replace in existing systems.
It offers full performance bi-flow capability, enabling quiet, precise performance for both cooling and heating.
The ETS 5M is also said to be ideal for high evaporating temperature DX computer room air conditioners (CRAC). Danfoss maintains that the mini EEV’s precise flow control and best-in-class protection against moisture and internal leakage improves system reliability in data centres where constant temperatures need to be maintained around the clock.
The new valve is electrically compatible with existing 12V drivers. It is compatible with low-GWP refrigerants, such as R32, and offers flexible system design potential. A large selection of brazing copper connectors is also offered for easy system design.
While the Danfoss ETS 5M is now available for small AC 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.
