What is the refrigerant used in the chiller and how much is used?

The refrigerant type and refrigerant charge are specific to the chiller model and configuration.

ATC chillers use different refrigerants depending on the product range and specification, so there is not one refrigerant type or charge that applies to all ATC equipment.

Where can I find the refrigerant information for my chiller?

The refrigerant type and charge for your chiller can be found on the rating plate attached to the unit.

The rating plate provides important information about the chiller’s specification, including:

  • Chiller model
  • Serial number
  • Refrigerant type
  • Refrigerant charge
  • Electrical information

The rating plate is typically located on the rear or side of the chiller depending on the model.

If you are contacting ATC about refrigerant information, a clear photograph of the complete rating plate is particularly useful.

Can I find the refrigerant information on the product specification?

Refrigerant information is also provided within the technical documentation for current ATC products.

However, if you need to identify the refrigerant in an existing chiller, particularly an older or legacy unit, always check the rating plate on the actual equipment.

This ensures that you are referring to the specification of your particular chiller rather than a different model or current equivalent.

Why does the refrigerant charge vary between chillers?

The required refrigerant charge depends on the design and specification of the refrigeration system.

Different chiller models and configurations can therefore use different refrigerants and refrigerant quantities.

For this reason, refrigerant charge should always be taken from the information provided for the specific unit rather than estimated from another chiller.

What if I can't find the rating plate?

If you cannot locate or read the rating plate, contact ATC.

Provide the model and serial number if available, along with photographs of the chiller and any other identification labels.

For older equipment, any original documentation or order information you have may also help us to identify the correct specification

Do I need the refrigerant information when requesting service?

It can be useful, particularly when requesting support for an older or third-party chiller.

If possible, send ATC a photograph of the complete rating plate rather than transcribing individual details. This helps our team to identify the equipment and its specification accurately.

See Where can I find my chiller serial number?and What information do I need when requesting technical support?” for further guidance.

If you are unsure which refrigerant or refrigerant charge applies to your equipment, contact ATC with the chiller model, serial number, and a photograph of the rating plate.
