DRE – Electric Water Heater
The DRE electric water heater is a three-phase appliance for commercial applications. Cascade control of the elements provides more efficient and faster heating-up times.
Fitted with 3 to 9 Incoloy elements, DRE provides a maximum rating of 54 kW. Each element is independently controlled via its own control thermostat (adjustable: 49 – 82°C) and a manually reset-able high-limit thermostat. The DRE features a safety float switch and AO Smith’s PermaGlas Ultra Coat second-generation glass coating technology helps to prevent corrosion.
All elements and thermostats are fuse-protected
Magnesium anode is replaceable
Optional ancillaries include unvented kits, destratification pump kit and powered anodes
The DRE water heater stores and heats water for sanitary purposes. Cold water enters the tank through the water inlet. The heated water leaves the tank at the top through the hot water outlet. When hot water is used, the tank of the water heater is filled with the same amount of cold water. Each row of heating elements contains its own control thermostat for precise adjustment.
