Most holding tanks will require their food and beverage contents be kept to predetermined temperature thresholds.

Depending on your requirements, we can custom design heating or cooling pads in the base and sidewalls on large tanks.

Our refrigeration and heating expertise means, in addition to our tanks, we are able supply solutions to regulate and maintain production temperatures of your vat.
