The company

Swiss made

As a pioneer in the manufacture of temperature control units for the plastics industry, HB‑Therm AG has been characterised by outstanding innovation, uncompromising quality and a strong commitment to sustainability since it was founded in 1967.

With a subsidiary in Siegburg, Germany, and 65 country representatives, HB‑Therm has a global presence and serves customers in the automotive, medical technology, consumer goods, optics and industrial sectors. With 140 employees, the company produces over 11 000 units annually and generates annual sales of around CHF 60 million, underlining its strong position as the largest manufacturer of temperature control units on the global market.

The secret of HB‑Therm's success lies in its corporate culture, which is practised on a daily basis and is based on deeply rooted values. As a Swiss family-owned company, HB‑Therm recognises the importance of long-term relationships, both with employees and with customers worldwide. Another key aspect is the commitment to sustainability, which is reflected in the continuous optimization of the carbon footprint. The high degree of in-house production and engineering under one roof at the St. Gallen site in Switzerland are key to HB‑Therm's pioneering role in developing the most energy‑efficient temperature control unit.

HB‑Therm has a clear mission to increase the efficiency of its customers. The latest generation of units, the Series 6, sets standards in terms of energy efficiency and guarantees optimum performance. Quality and durability are a matter of course for HB‑Therm, underpinned by the unique selling point of the lifetime guarantee on the core components of the heater and flow meter.
