HotCat Benefits


  • Water baths can weigh 4X to 5X more than a HotCat of equivalent capacity.
  • Less foundation is required for HotCat.
  • Initial glycol fill-up is costly: $8-10 per gallon.
  • HotCat uses less real estate - a major, recurring taxation expense.
  • HotCat can be installed in Class 1, Division 2 Group D areas; water baths must be outside
    classified areas.
Conditions HotCat Water Bath
Foundation Weighs a fraction of what's needed for a
water bath
Heavy foundation support
Visibility Under 11 ft. Tall stacks required; problems
in residential areas
Ethylene Glycol Chemical Charge No costly chemical fill-up needed Initial fill-up charge, delivery charge, maintenance
Hazardous Area Locations Approved for Class1, Divisions 2,
Group D areas
Must be installed outside
classified area
