HIGH-EFFICIENCY CONTROLLERS FOR PROFESSIONAL REFRIGERATION
The B-Series covers compact all-in-one (BR5), DIN-rail (BR1-27) and split-mount power-unit (BD1-28, BR1-28) refrigeration controllers, with dedicated outputs for Variable Capacity Compressors (VCC) or EC variable-speed fans and enhanced ECO energy-saving management.
