is a dedicated controller designed specifically for refrigeration machine rooms. It acts as the "brain" of the compressor rack, managing:
The "S" version often features . It handles "drip time" and post-drip fan delays more gracefully than standard models, preventing frost blow-back into cold rooms.
The EWCM 900 S is designed for industrial environments, ensuring durability and ease of installation.
: Controls both the compression and condensation phases by managing compressors and condenser fans simultaneously.
Supports homogeneous units (identical capacities), non-homogeneous units (different capacities), and partially staged systems. eliwell ewcm 900 s
Racks where compressors vary in size and power ratings, requiring asymmetric staging.
