A large Midwest, USA, pet food processor needed to replace their large shell and tube heat exchanger that supplied hot water to a tank and then out to a large recirculation system. Scaling was a major issue on the heat exchanger as well as high energy usage. The plant also needed to make sure it had enough hot water at the right temperature for peak usage hours.

SOLUTION
A 4-inch EZ Heater® three-way valve was installed which now supplies hot water on demand for their processing floor. This system supplies hot water instantaneously for hose stations, spray bars, spray balls in tanks and general wash-down needs. The EZ Heater never clogs or fouls and only requires a once-a-year maintenance schedule. The company now saves energy and maintenance time. Their uptime has greatly increased and, as a result, so has their production.
GOAL
• Eliminate scaling
• Reduce energy usage
• Precise hot water on demand at peak usage hours
ACCOMPLISHMENTS
• Instantaneous hot water on demand
• No clogging or fouling
• Low maintenance
• Increased uptime and production
