Advanced System At A Company In Southern Germany Acts As A Model For The Entire Industry


In fact, the system exceeded the expectations of Willibald Hergeth, managing director of TRANSpofix GmbH: “I have to say that the savings up until now have truly been immense. All of the components of the CCHP system work flawlessly together, and we have had practically no downtime thus far.”

A 3,500-liter hot-water buffer tank is located in the same room as the three adsorption cooling units, and this tank holds the heat that is not directly fed into heating the building or to power the adsorption cooling units. The same applies to the cooling side: Here the company installed a 2,000-liter cold-water buffer tank to meet its needs in the event of a high demand for cold water. Both buffer tanks are controlled as needed, using pump regulation so that a shortage is virtually impossible.

Stephan Heizungsbau put the CHPs into operation in December 2012, with the adsorption cooling units being added in May 2013. Andreas Stephan is extremely satisfied with the entire system: “Installation was smooth, and the initial data confirmed the system’s incredible effectiveness. Since we make full use of the waste heat from the CHPs, the entire system’s amortization period was reduced by a significant amount. I am confident that we will be seeing much more of this kind of CCHP system in the injection molding industry in the future. Our collaboration with InvenSor GmbH was extremely professional, and we will continue to expand this relationship.” Stephan expects the three CHPs to have an annual operating time of approximately 7,500 hours.

In order to use the CCHP system in a new production hall as well, Andreas Stephan already installed a fourth CHP unit in November 2013 so that the company can also affordably generate its own electricity and heat here as well.

The InvenSor adsorption units are some of the most user-friendly on the market. For example, the target temperatures for cold water and the recirculation back into the driving cycle are extremely easy to set using the multilingual color-touch display. In addition, the unit is already set up for use in heat pump mode, which can be activated on the device. Using the hydraulic system already integrated into the unit, specialists and planners can implement their special solutions, such as the use of free cooling on cold days, without much increasing the entire system’s complexity and risk of malfunctions. The easy-to-operate start-up mode, automatic operating optimization, and the internet interface which is the included standard combine to make devices from InvenSor into plug-and-play devices that are easy to operate even without significant prior knowledge.
