Electric Reefer Technology

The ER-230 and ER-460 are all-electric stationary refrigeration units for the cold storage industry. They are installed in remanufactured frame and coil set systems with all new electrical and refrigeration, and feature a scroll compressor, fan motor, and controls using three-phase power and R404A refrigerant for cooling and heating. The ER-230 runs on 230 VAC power; the ER-460 runs on 460 VAC power.

In short, the ER-230 and ER-460 are reliable, quiet, efficient, high-capacity, zero-emissions, low-maintenance cold storage solutions.


  • Starts and stops automatically to maintain temperature in the cargo area.
  • Temperature control is fully adjustable in cool, heat, and null cycle from -20°F to 90°F (temperature is selectable in Fahrenheit or Celsius).
  • Phase-detect module with indicator light monitors the compressor rotation and stops it if an error is detected.
  • Defrost automatically activated by pressure switch or timer.
  • Defrost by manual switch if preferred.
  • Overload protection for compressor and fans.
  • Designed to tolerate voltage variances.
  • Scroll compressor (hermetic) for highly efficient low power comsumption and smooth operation.
