Operational Benefits• Only heat to duty required• 4-16 zones• High turn-down ratio – 8:1 to 32:1, or more• Annual operating costs dramatically lower than water

baths thanks to superior heat transfer efficiency:

Conditions Hotcat Water Bath

Maintenance Benefits• HotCat requires minimal maintenance; just change the

fuel filter.• No moving parts• No corrosion• No tube bundle maintenance• No burner maintenance• No boil-off

Environmental Benefits• Virtually zero VOCs• Virtually zero NOx• Silent operation• No hazardous chemicals• No containment ring• No maintenance for chemical charge• No odor• No permitting necessary, except some states require

permits for units 1,000,000 BTUH and above.
