Directly cooled temperature controllers are suitable for all plastics processing applications where high cooling performance and high heating capacity (for a quick heating-up of the mould) are both required. Wittmann’s new models of the Tempro basic C120 series present much-reduced dimensions. This series offers many variants in regard to different pumps and different heating and cooling capacities. With the biggest version of this series, injection moulders are also able to heat up moulds weighing up to 10 tons to the desired operating temperature and within the shortest time period.
The smaller Tempro basic C120 unit has dimensions of just 230 × 690 × 630 mm. This particular unit can achieve a delivery rate of up to 200 l/min. It comes with a heating capacity of either 12 or 18 kW at a pump capacity of 0.75 or 1.5 kW. Furthermore, there are many options that can be chosen: serial interface, external sensor, alarm contact, internal bypass for relieving the pumps, and also manual mould purging.
The most powerful model of the series has dimensions of 340 × 776 × 700 mm. Thus far, the heating capacity of directly cooled units had been limited to18 kW. But now, this Tempro basic C120 model is available with either 18 or 24 kW of heating capacity, and can also be adapted to heating capacity of 46 kW – this feature being entirely new. The respective pump capacities range from 200 to 280 l/min.
