The Guardian Controls Crankcase Heater Optimiser (CCH) has been specifically developed to reduce the energy consumed by compressor crankcase heaters.
Compressor crankcase heaters being on when they’re not required is a continual source of energy, especially for idle packs. The CCH continually assesses the pack pressures and plant room temperatures to determine if it’s safe to inhibit the crank case heater power. Further energy savings can be made by inhibiting the ventilation fans if conditions allow.
The CCH can monitor and optimise crankcase heaters for up to 10 compressors on a pack and 1 ventilation fan. Assessing the plant room temperatures and pack pressures is vital to avoid oil slugging and flood back.
Savings of up to 75% can be delivered.
- Annual Energy Savings of up to 75%
- Straight forward retrofit to existing packs as part of any energy saving programme.
- Compatible with existing control equipment.
