Automatic refrigerant charge system

Automatic refrigerant charge system

Developing high-efficiency refrigeration systems requires accurate, repeatable, and flexible control of the refrigerant charge. Re/Gent’s Automatic Refrigerant Charge System is designed specifically for R&D laboratories and prototype development, enabling engineers to determine the optimal refrigerant mass quickly, safely, and with high precision providing the opportunity to automatically evaluate the performance for different refrigerant quantities.

Whether you are testing a refrigerator, freezer, display cooler, heat pump, or any other refrigeration system prototype, the unit allows fully automated charging with a wide range of refrigerants including R600a and R290.

The system eliminates the trial-and-error approach common in manual charging and provides consistent results essential for performance development:

Traditional prototype charging requires manual weighing, manual dosing, and manual valve operation, all sensitive to mistakes that affect system performance and test repeatability.

The Automatic Charge System solves these issues: 

  • No manual weighing
  • No manual valve control
  • No need to disconnect hoses between adjustments 

Charge mass is controlled digitally and delivered with high accuracy, ensuring the prototype is always charged with the intended amount.

The system allows rapid iteration during development: 

  • Automatically evacuate, charge, and adjust refrigerant mass
  • Test multiple charge levels
  • Identify the optimal charge for efficiency, capacity, and compressor operation
