Challenge
• Need to heat 30 GPM from 60°F to 120°F, which requires 263
kW (900,000 BTU/h) of power
• Washdown cycle time can be reduced 50% by using hot water
• Hose station is at the far end of the plant
• Piping of natural gas is complex and costly
• Natural gas red boilers create explosion hazard
• Plant has steam but piping of steam and condensate would be
in excess of $60,000 in addition to the cost of the steam driven
water heater
• Need a low maintenance solution that is simple to operate
Solutions
Eemax application engineers were engaged to specify the system
based on customer requirements.
The Eemax tankless units provide high volume hot water on-
demand with little to no maintenance. Piping the heaters in parallel
equates to 10 GPM ow through each heater resulting in only 6
PSI total pressure drop. The heaters are piped to a hose station
150 ftaway. Simply opening a gate valve at the hose station
activates the heaters. Like most industrial facilities, this plant had
no issues locating adequate electric feeds.
