Features
The internal design of our Direct-Expansion Chiller Barrels have been engineered for optimum heat transfer. The construction utilizes enhanced copper tubing for increased surface area and better heat transfer, without increasing the overall size. In addition, baffles are placed within our chillers to direct the water flow for maximum cooling effect. Externally, the entire chiller is wrapped in 3/4″ insulation for maximum temperature retention after being powder coated for enhanced corrosion resistance.
