Hatco MC-11 Mini-Compact Electric Booster Water Heater, 11.4 kW, 3.2 Gal., 240/480V
Description
A small 11.4 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-11 is an 11.4 kW Mini-Compact electric booster water heater. It stores 3.2 gallons in a stainless steel tank and recovers 114 gallons per hour at a 40°F temperature rise, or 65 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. Choose 240V 1-phase, 240V 3-phase or 480V 3-phase power when you order.
Will it fit · Will it hook up
- Outside size
- 11.72" W x 12.88" D x 18.5" H on the standard 6" legs; leave room to inspect and test the temperature/pressure relief valve
- Power
- 240V 1-phase 47.5 A, 60 A breaker; 240V 3-phase 27.5 A, 40 A breaker; 480V 3-phase 13.7 A, 20 A breaker. Hard wired: the electrician supplies the breaker or fused disconnect
- Water
- 3/4" NPT inlet and outlet; incoming water over 3.0 grains per gallon hardness must be softened
- Location
- Indoors, 70°F room or warmer, as close to the dishmachine as possible; recirculate if the run is over 5 ft. (NSF)
- Clearance
- Front access to the controls; Hatco recommends at least 2" at the sides
Have the electrician confirm the voltage, phase and circuit before the heater arrives: Hatco electric boosters are hard wired with no cord or plug.
114 GPH recovery
At 11.4 kW the MC-11 heats 114 gallons per hour through a 40°F rise and 65 gallons per hour through a 70°F rise, for a 180°F final rinse.
Stainless steel tank
The 3.2-gallon stainless steel tank is wrapped in fiberglass insulation, and the heater recovers fast for its size.
Low-water cut-off
A low-water cut-off keeps the elements off when the tank is low, and a high-temperature limit switch adds a second safety.
Factory plumbed and wired
It arrives pre-plumbed and pre-wired with an immersion thermostat, temperature/pressure relief valve, pressure reducing valve and two temperature/pressure gauges.
Delivery and setup
- Inspect the carton for damage before you sign, and note any damage on the delivery receipt. Approximate shipping weight is 48 lb.
- Installation must be done by qualified installers to local electrical and plumbing codes. Installation by unqualified personnel voids the Hatco warranty.
- Fill the tank with water before you turn on power: the elements burn out if they run dry.
- Set the pressure reducing valve to 20 psi flow pressure, and do not fit a check valve or anti-siphon valve in the supply line to the booster.
- Pipe the temperature/pressure relief valve discharge to a safe place of disposal, per local code.
Questions buyers ask
Is it big enough for my dishmachine?
Size it by the gallons per hour your dishmachine rinse uses and your incoming water temperature. The MC-11 recovers 114 GPH at a 40°F rise (140°F in, 180°F out) and 65 GPH at a 70°F rise (110°F in). If your machine uses more, step up in kW.
What electrical service does it need?
Pick the voltage and phase you have on site: 240V 1-phase draws 47.5 A on a 60 A breaker; 240V 3-phase draws 27.5 A on a 40 A breaker; 480V 3-phase draws 13.7 A on a 20 A breaker. It is hard wired by a licensed electrician.
Can the phase be changed later?
No. Mini-Compact heaters are not field convertible, so the phase must be specified when ordering.
Does my water need treatment?
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.
What warranty does it have?
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.
