Tempro basic E Wittmann has improved upon its 20-year-old Tempro basic C series of temperature-control units (TCUs) with this new series, which it intends to eventually offer in small, medium and large units. Units in the series feature a sealless peripheral impeller pump with a highly efficient asynchronous motor. Heat loss is prevented by direct heat transfer from the heating elements to the tempering fluid. The TCUs’ tubular cooling coil has an enlarged heat transfer area that ensures a higher cooling performance as well as a longer service life of the heat exchanger.
What’s new? The Tempro basic E S90 — the first and smallest unit planned in the Tempro basic E series. Wittmann plans to introduce two bigger sizes eventually, with the biggest in the series to come out next; the company expects that unit to offer a heating capacity of 36 kilowatts, with a maximum pump output of about 74 gallons a minute. Included with the Tempro basic E series is a completely redesigned, easier-to-use operating terminal and new 3.5-inch screen.
Benefits Ease of use, process reliability and competitive pricing. Compared to the Tempro basic C series, the Tempro basic E temperature controllers are more energy-efficient and more compact. The TCUs now are easier to install below IMMs and inside automation cells, and no longer take up any separate floor space. The Tempro basic E S90, for example, is about an inch narrower and 2 inches shorter than the Tempro basic C90. Also, the new TCUs are easier to maintain.
