Industrial environments demand rugged, deionized-water heaters—and this model meets the challenge. Built for tight spaces and tough conditions, the iQ251D is the most compact and only gas-fired deionized tankless water heater on the market. Count on this unit to deliver efficient, consistent, durable performance in diverse applications—industrial finishing/cleaning; electronic parts fabrications; food processing; water purification; reverse osmosis systems; as well as the aerospace, cosmetics, pharmaceutical and glass industries.
A Cascaded System with Independent Operation
LARGE CAPACITY, NO SINGLE-POINT FAILURE
The iQ251D units can be cascaded—up to 10 altogether—for a combined capacity of over 2,500,000 Btu/h. Best of all, these heaters do not require a master controller (the kind that can cause single-point system failure). With Intellihot’s patented design, each unit has enough internal logic to operate independently. In fact, if any one unit needs to be checked or serviced, the other units will continue to function smoothly to ensure continuous hot water.
