The temperature control unit – A glimpse into the future
At K 2016 (hall 10, stand J39), gwk (gwk Gesellschaft Wärme Kältetechnik mbH of Meinerzhagen, Germany) will be presenting the design study for a new, universal temperature control unit. According to the manufacturer, the successor to the teco cs series is intended to meet the key criteria that globally surveyed fabricators demand of universal temperature control units for general-purpose applications. The aim is to provide sophisticated but affordable technology with a modern industrial design, which has good availability, is easy to use, is service-friendly and customisable, and is also adaptable in stages for the comprehensive process monitoring and requirements of Industry 4.0. When designing the future series, the first versions of which are to be available from mid-2017, the developers at the temperature control specialists in the Sauerland not only applied the positive experiences gained with the proven teco cs series, but also took into account the new production concepts that have been implemented following the company's move from Kierspe to Meinerzhagen. Even with the existing series the company has managed to double annual production within two years with the aid of a gps (gwk production system) developed specifically for the new plant.
As part of the "Temperature Control Unit" project, the first model of the new series to be produced is a 95°C water version, which can be used worldwide for 75 percent of all injection moulding applications with standard plastics, according to Helmut Gries, Director of Sales and Marketing. "We see the demand for the new generation of units primarily in the international growth markets, but also among thoroughly demanding but price-oriented customers in Europe. Furthermore, there are a large number of application areas outside the injection moulding industry. Mind you, the new temperature control unit will not be a cheap item, but a sophisticated, state-of-the- art temperature control unit incorporating our new 32-bit controller, which in the advanced version will be Industry 4.0-compatible. But even in the basic version, the unit will be the preferred solution for many applications, with an excellent price/performance ratio."
The fundamental features of the basic version include microprocessor control with the display of target and actual temperatures, automatic top-up, automatic mould draining, energy-saving heating control and much more. The customisation options include various interfaces, customised colours and labelling, roller-mounting, rubber buffers or rails and other useful items. The design study presented at K 2016 has a heating output of 9 kW, an indirect cooling system with a cooling output of 23 kW at 15/90 °C coolant/ambient temperature and a sealless submersible pump with a maximum throughput of 60 l/min.
