Innovations even in the range of standard temperature controllers
gwk temperature controllers teco

 

On the occasion of the Fakuma 2014 gwk Gesellschaft Wärme Kältetechnik, Meinerzhagen, presents for the first time its new distribution system with 4 respectively 8 circuits that can be adapted to temperature controllers of the teco series for the individual monitoring of flow quantities and return temperatures.

 

The multiple distribution system vtc has been designed for the attachment to temperature controllers to adjust and monitor individually the flow volume and the return temperature of parallel connected consumer circuits.

 

Thus the system ensures the hydraulic balance in the temperature control circuits with differ-ent pressure losses and ensures an economic and reliable distribution of the flow rate deliv-ered. The flow rate and the return temperature of each circuit is indicated on the central display of the temperature controller. The process monitoring is performed by the adjustment of minimum and maximum limit values for the flow rate, return temperature and differential temperature per circuit. In addition, process performances per distribution circuit are displayed. When the tolerance band is exceeded alarm functions are activated and displayed.

 

Besides the development of the multiple distribution system gwk Gesellschaft Wärme Kältetechnik mbH advanced the continuous extension and modernisation of their range of single temperature controllers and adapted these to the changing market requirements in close cooperation with customers.

 

Temperature controllers of the teco series are designed for the operation with water and are available with direct or indirect cooling up to 95 °C, 140 °C, 150 °C, 160 °C and 200 °C. Equipped with heating capacities up to 72 kW, cooling capacities up to 600 kW and flow rates up to 500 l/min this series in modular design is suitable for nearly all applications in the plastics processing industry. Higher capacity requirements are covered by the tecma series.

 

Temperature controllers of the teco series that are operated with thermal oil cover tempera-ture requirements up to 180 °C, 300 °C or 350 °C depending on the design.

 

All standard units are equipped with an energy efficient constant heating control. Depending on the product version a flow rate measurement and control, whose actual value is indicated simultaneously with the actual and nominal values on the colour screen, is installed as standard or is optionally available. Temperature profiles are graphically indicated after selec-tion of the corresponding menu function. By a simple touch on symbols on the start page useful functions like limit value monitoring, leak stop operation etc. can be selected. In order to supplement the operational safety maintenance intervals and advices are indicated as clear text on the service page.

 

The teco cd series was supplemented by a directly cooled temperature controller für the temperature range up to 140 °C.
