Made with Breweries in Mind

Chase Cooling Systems’ brewery specific units have cooling capacities up to 4 tons based on glycol temperatures typically required for brewing processes. Larger capacities may be available upon request. The plug-and-play design comes preassembled with all necessary adjustments already made and is ready for installation & startup upon delivery. The package includes a standardized pump and compressor.

Standard construction on these glycol chillers includes a powder-coated galvanized steel cabinet, microprocessor temperature controller, and all necessary instrumentation and safety devices. An optional stainless-steel cabinet provides enhanced corrosion protection and cohesion with other common brewery equipment.

Brewery Specific Modifications

  • Fluid circuit configured with warm tank to minimize back pressure on brewing equipment
  • Insulated fluid hoses to minimize sweating
  • Controller programming adjustments for proper customizable temperature control
  • Low pressure safety switch selection for system protection
  • Thermal expansion valve (TXV) adjustment to maintain proper superheat
  • Can accommodate glycol concentrations up to 50%

Modifications make these units appropriate for low glycol temperatures and satisfy most brewery requirements. Further customization may be available. Contact a Chase Cooling Systems representative with your requirements for more information.
