AnEconomicalSolutionToYourHotWaterHeatingNeeds...The design of the Thrush Hot-Pak® facilitates the semi-instantaneous heating of water, allowing for a constant supply of hot water to any commercial or industrial application. This pre-engineered system provides an economical solution to the expense of large storage tank systems. In addition, its space-saving vertical or horizontal design makes it ideal for tight installations.

• Steam to water design• ASME Sec. VIII Div. 1 construction• Copper tubing (single or

double wall)• Naval brass tube sheet• Brass tube bundle supports• Brass Baffles• 304 stainless steel shell with

anticipation plate• Shell insulation with sheet

metal jacket• 3 Speed Wet Rotor Circulator

with isolation valves – allows for adjustment to the de-stratification and anticipation level
