: Manages condenser fans based on head pressure to maintain system stability.

The Eliwell EWCM 900 S is often used in various applications, such as: : Housed in a standard 72x144 mm front-panel

The physical layout of the EWCM 900/S is designed for straightforward integration into industrial electrical panels. Inputs and Outputs (I/O)

and 11 optoisolated alarm inputs Sensors

The controller also manages the condenser fans on a common header to maintain an optimal head pressure for your equipment. Fan staging can be configured for (e.g., a predetermined sequence like compressor 1 then compressor 2) or rotating/alternating , which is recommended for homogeneous fans. You can also program a minimum off-time for fans to prevent short cycling, reducing wear on the fan motors. Market Availability & Pricing Check system charge; inspect

: 11 configurable relay outputs (6(3)A 250V AC) for compressors and fans.

The Eliwell EWCM 900 S offers a range of advanced features that make it an ideal choice for commercial refrigeration applications. Some of the key features of the controller include:

The controller offers multiple sequencing modes, including (First-In, First-Out), LIFO (Last-In, First-Out), and Runtime Balancing . Runtime balancing ensures that all compressors accumulate equal operating hours, preventing premature failure of a single unit. 2. Condenser Control
