Cold Storage & Refrigeration
Compressor protection for cold rooms and refrigeration plant, where a voltage dip can mean lost stock.
A cold storage compressor under low voltage draws more current to do the same work, which is exactly the condition that overheats a motor and trips it out, and every trip is a stretch of time the room isn’t holding temperature. On a facility running multiple compressors off the same feeder, a brief dip or a power cut can also mean every unit restarts into the grid at the same moment, which is its own kind of stress on both the motors and the supply. Frozen and chilled stock doesn’t forgive a stopped compressor the way most other equipment forgives downtime, so the margin for a voltage-related fault here is smaller than in most industrial settings.
Compressor Overload Protection
Corrects low voltage before it forces a compressor to draw excess current and overheat.
Staggered Restart
Start delay on multi-compressor sites prevents every unit restarting into the grid at once after a power cut.
Three-Phase Correction
Corrects each phase independently on facilities running larger, three-phase refrigeration plant.
Continuous Duty Rated
Built for round-the-clock operation, matching how a cold room actually runs.
Wide Input Voltage Range
Handles the drops and surges common on the feeders serving industrial and warehouse sites.
Sized to Connected Load
Specified against the facility's total refrigeration load rather than a single compressor.
