Frequently Asked Questions

What size reservoir can this chill?

This unit is best suited to reservoirs sized to its rated pump flow range. Match your reservoir volume and ambient temperature to the chiller's capacity rating for best results.

How do I choose the right pump flow rate for this chiller?

Use a pump rated between 264 GPH minimum and 660 GPH maximum. Running a pump outside this range can reduce chilling efficiency.

Is R134a refrigerant environmentally safe?

Yes — R134a is a freon-free, environmentally safer alternative to older refrigerants with high ozone-depletion potential. It is widely used in modern consumer and commercial cooling equipment.

Does this chiller have overcurrent protection?

Yes — the overcurrent protection system and temperature memory protect the compressor and maintain your settings during power fluctuations. Your set temperature is retained even after a brief power interruption.
