Heating/Cooling: Temperature Control Unit Meets New Energy Conservation Standards
New temperature control unit satisfies Department of Energy (DOE) 2020 conservation standards, with higher outputs from less energy consumption.
The new Eco Series temperature control units from Delta T Systems are compliant with the DOE Energy Conservation Standards, which, among other things, regulate industrial pumps and take effect on Jan. 27, 2020. Delta T says these pumps produce higher outputs measured in flow and pressure compared to the existing design. In addition, the energy consumption is significantly reduced. A company spokesperson told Plastics Technology that the Eco Series utilizes a completely new pump design.
The spokesperson said the new pump design creates 50% to 100% more flow at the same pressure point on the pump curve compared to the current design, with water temperatures up to 300F possible. The system also applies a 2-tank design, differing from the current single tank, and can go up to 24kw. A specially designed heat exchanger can be used in the second tank for indirect cooling.
In terms of output, the spokesperson said the first Eco release includes pumps from ¾ to 3 hp. The ¾-hp unit increases output from 50 to 90 GPM, while the 3-hp unit will increase from 75 to 130 GPM. “Due to this higher output, customers can select lower horsepower motors which in turn lowers the energy consumption,” the spokesperson said.
Built-in safety features include a bi-metal switch that protects the heater from overheating, circuit protection for the motor, high-temperature pump seal and a dry-run protection for the heater. Additional design improvements lift-off panels on the side for easy access, IEC compliant components, and a compact heater design, allowing higher capacity on a smaller footprint.Related Content
