The Open Tank Design is ideal for two scenarios: bad supply water quality or no water supply. The small amount of water circulating in this closed loop system makes it easy to chemically treat.

The system is portable and operates with low water pressures.

Delta T Systems’ Open Tank Design (TCU) utilizes a new pump design that creates 50% to 100% greater flow at the same pressure point on the pump curve, as compared to other current designs. This new pump’s reduced energy consumption allows the series to be compliant with the Department of Energy’s (DOE) 2020 Conservation Standards that will take mandatory effect as of January 2020.

Open Tank Safety Features:

  • Bi-metal switch that prevents overheating
  • Circuit protection for the motor
  • High temperature pump seal
  • Dry run protection for the heater

Additional Open Tank Design Improvements:

Design improvements and material selections make the Eco Series temperature control units less susceptible to traditional maintenance problems, and easier to maintain.

  • Industrial strength frame and cabinetry
  • Lift-off panels for easy access
  • IEC and UL compliant components

Compact heater design allows higher capacity in a smaller footprint.
