Replacing glycol pump / brine pump, water pump and compressor motors with new energy efficient motors helps save electrical energy through decreased usage and makes the refrigeration plant more efficient.

Install high-efficiency motors, soft start controllers:

Using motors with a high-efficiency rating will increase the total system efficiency. Arenas can install soft-start controllers on the compressor motors. Soft-start controllers reduces inrush current and the resulting peak demand loads and reduces the strain on the compressor during the high torque generated at start up.

Check with utility companies, as power bills can be reduced by using a soft-start controller and will depend on the method used to calculate the demand load.

Benefits: 

  • Reduced cost
  • Rebate programs they may offer to help pay for the greater efficiency

Savings: 

  • Electricity
  • CO2
