Building off the 2019 release of the Tempro plus D M100 pressurized temperature control unit (TCU), Wittmann Battenfeld is introducing directly cooled, pressurized TCUs, including its first directly cooled dual-circuit unit. As part of a virtual roll out of products it would have launched at the cancelled Fakuma event, Wittmann Battenfeld introduced the directly cooled Tempro plus D M120 in single- and dual-circuit versions. The company said the product launch was based on market research that revealed strong interest in a directly cooled pressurized unit of the same size as the Tempro plus D M100.

Providing two independent temperature control circuits, the Tempro plus D M120 features a durable piston cooling valve to endure the high wear demands of direct cooling. The company says this valve can withstand the high number of switching cycles with less maintenance, providing longer service life than a conventional membrane cooling valve.

As standard, the Tempro plus D M120 supplies direct cooling capacity of 80 kW with an Delta T of 75C. In addition to the standard 9-kW heating capacity, models with capacities of 12 or 16 kW are also available. Wittmann notes that it only uses stainless steel pumps with wear-free magnetic couplings, which cover a range of maximum flow rates from 40 to 90 l/min. A frequency-controlled pump with 1.1 kW, 50 l/min, and 9 bar is also available.

Wittmann notes that the advantage of a frequency-controlled pump installed in the directly cooled Tempro model is flexibility in control parameters, with a choice of operations being dictated by motor speed, pressure or flow rate. The new Tempro comes with a Wittmann 4.0 interface as standard, enabling integration of the TCU into the work cell’s control system.
