Plastic and textile industry

Heat for drying, dyeing and kneading

Coating systems for artificial leather production, stenter frames for drying textile fabrics, dyeing systems, calenders, washing and ironing machines, kneading and vulcanising machines: Many production steps in the plastic and textile industry require reliably linear process heating – and need to be fit for the future. That’s where we come in: with compact electrical heaters that guarantee low-CO2 processes even in confined production environments; with temperature control equipment that ensures sensitive synthetic materials do not overheat, burn or harden in the production process; and with powerful WTÖ systems suitable for seamless integration into your manufacturing processes. You benefit from solutions perfectly tailored to you from our in-house engineering department, offering stable, future-proof operation that will continue to run efficiently in 20 years’ time.

    We know the standards

    As a pioneer in the thermal oil industry, we helped develop the fundamental standard DIN 4754 and know it inside out.

Textile dyeing and drying

Process heat for fresh textiles

Having our own experienced engineering department always pays off when off-the-shelf goods don’t do the job. Accordingly, one of the world’s leading process system manufacturers for the textile industry benefited from the creativity of our engineers. Not least because the heat supply for their mangles and wash lines turned out to be a challenge due to space constrictions – right up our street! We managed to work with the customer to create a tailormade heater with WTÖ technology and the right dimensions. It’s been used in all their systems ever since – in presses, washing machines, ironing equipment and washing systems. The thermal oil heater can be used variably in an output range of 200–1,000 kW and reliably supplies temperatures around 300 °C.

Film production

Precise temperature control for calenders

When one of the world’s leading manufacturers of process systems for calender rolls commissioned us to design a temperature control solution, it soon became clear that this was no small task. The calender in question was intended for film production, which only achieves high-quality results when temperatures are precisely controlled. The challenge: The mechanical stress of the rolls also generates heat in addition to the process heat which must be offset immediately. We solved the problem using a CPS temperature control system that keeps the temperature firmly on track with 150 kW of cooling and 250 kW of heating output. The heat carriers used were thermal oil in heating and water for cooling.
