The Eco Series water temperature control system is our most popular TCU. The new pump design is compliant with the DOE Energy Conservation Standards. These pumps produce higher outputs measured in flow and pressure compared to the existing design. In addition, the energy consumption is significantly reduced.
- ¾ to 7.5 HP Pump, 25 to 160 GPM
- 9 to 72KW Low Watt Density Heater
- 2 tank design
- Direct or indirect cooling
- 250°F (121°C) Fluid Operating Temperature
Delta T Systems Eco Series temperature control unit (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 Eco Series to be compliant with the Department of Energy’s (DOE) 2020 Conservation Standards that will take mandatory effect as of January 2020.
Eco Series Safety Features:
- Bi-metal switch that prevents overheating
- Circuit protection for the motor
- High temperature pump seal
- Dry run protection for the heater
Additional Eco Series 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.
