Hatco MC-15 Mini-Compact Electric Booster Water Heater, 15 kW, 3.2 Gal., 208V 3-Ph
A small 15 kW electric heater that delivers 180°F water for hot water sanitizing from a 3.2-gallon tank that fits almost anywhere.
The Hatco MC-15 is a 15 kW Mini-Compact electric booster water heater. It stores 3.2 gallons in a stainless steel tank and recovers 151 gallons per hour at a 40°F temperature rise, or 86 gallons per hour at a 70°F rise. Hatco builds the Mini-Compact for hot water sanitizing and point-of-use hot water, on standard 6" legs. It runs on 208V 3-phase power.
Have the electrician confirm the circuit before the heater arrives: Hatco electric boosters are hard wired with no cord or plug.
At 15 kW the MC-15 heats 151 gallons per hour through a 40°F rise and 86 gallons per hour through a 70°F rise, for a 180°F final rinse.
The 3.2-gallon stainless steel tank is wrapped in fiberglass insulation, and the heater recovers fast for its size.
A low-water cut-off keeps the elements off when the tank is low, and a high-temperature limit switch adds a second safety.
It arrives pre-plumbed and pre-wired with an immersion thermostat, temperature/pressure relief valve, pressure reducing valve and two temperature/pressure gauges.
Size it by the gallons per hour your dishmachine rinse uses and your incoming water temperature. The MC-15 recovers 151 GPH at a 40°F rise (140°F in, 180°F out) and 86 GPH at a 70°F rise (110°F in). If your machine uses more, step up in kW.
208V 3-phase, 41.7 A, on a 60 A breaker or fused disconnect. Hatco's manual lists 6 AWG copper wire. The unit is hard wired by a licensed electrician.
No. Mini-Compact heaters are not field convertible, so the phase must be specified when ordering.
Yes, if it is hard. Water over 3.0 grains of hardness per gallon must be treated and softened before it reaches the booster. Failure from liming or sediment is not covered by the warranty.
Hatco covers the booster tank for 1 year parts and labor plus 9 more years parts only. Other parts carry Hatco's standard 18-month limited warranty. Register the unit with Hatco within 90 days of factory shipment to qualify for added coverage.
