The Hubbell Model JTX electric tankless booster heater contains high powered heating elements that heat water only
when there is demand from the dishmachine. When hot water is needed, a built in flow sensor measures the exact flow
rate and that data combined with temperature readings at the heater’s inlet and outlet are processed by the electronic
temperature controller. This data is continuously transmitted to the temperature controller, which constantly calculates
the precise amount of power (kW) needed to achieve the desired temperature. A zero cross over firing signal is sent to
the heater's fast acting triacs in order to modulate the heating elements to the precise level needed to meet demand. The
Hubbell tankless booster heater uses only as much power as is needed, while delivering accurate and consistent hot water
temperature.
How It Works
Hubbell Tankless Booster Features
Heater Overview - 3 Element Model Shown
By heating water more efficiently... over 98% efficient... and essentially eliminating standby heat
loss, the typical owner will save over 2300 KW·HRs per year! Add to that the reduced maintenance
costs of the Hubbell tankless booster compared to a tank type booster and the annual savings easily
add up to over $750 per year.
2300 KW·HRs x $0.16 per KWh = $368.00 Annual Energy Savings
Tankless Booster Saves Money
Free up floor space, improve the look and cleanliness of your kitchen, and improve the longevity of
your booster when you mount the Hubbell tankless on the wall.

Note: The Hubbell Model JTX is designed for use with conveyor and flight type dish machines only. This product may not
operate as expected if the dish machine is other than a conveyor or flight type.
