Used HB-Therm Equipment Sold by Meadoworks

HB-Therm AG was founded in 1967 in St. Gallen, Switzerland, and has grown from a regional specialist into the world's largest manufacturer of temperature control units for the plastics industry. A Swiss family-owned business, the company produces exclusively at its St. Gallen facility and maintains a subsidiary in Siegburg, Germany, along with representatives in more than 60 countries. Its quality and environmental management systems are certified to ISO 9001 and ISO 14001, and the company has built its reputation on a philosophy of uncompromising Swiss-made quality.

HB-Therm's core product line centers on water and oil temperature control units for injection molding, spanning generations from the widely adopted Series 4 and Series 5 through the current Series 6. The flagship Thermo-5 water temperature control units handle temperatures from 100 °C up to 230 °C for water and 250 °C for oil, featuring sealless stainless-steel pumps, maintenance-free ultrasonic flow measurement, and a closed system that prevents oxygen contact and corrosion. The current-generation Thermo-6 builds on that proven platform with a speed-controlled Direct-Drive pump for greater energy efficiency, a standard Ethernet OPC UA interface for machine integration, and an expanded lifetime warranty covering both the heater and the ultrasonic flow meter. The Series 6 portfolio also includes the Flow-6 multi-circuit water flow measurement and control unit, variothermal switching units for dynamic mold temperature control, and mold cleaning units.

HB-Therm temperature control units serve manufacturers across the automotive, medical technology, consumer goods, optics, and general industrial sectors — anywhere that precise, repeatable mold temperature management is critical to part quality and cycle efficiency. The company's variothermal switching units are particularly valued in high-surface-quality applications such as automotive interior trim and optical components, where dynamic heating and cooling of the mold cavity directly affects the finished part.

Buyers seeking used HB-Therm water temperature controllers consistently cite the brand's exceptional build quality and longevity as primary reasons to source pre-owned units. The all-stainless hydraulic circuits, indirect-contact heating elements, and maintenance-free ultrasonic flow meters mean that well-maintained units retain reliable performance well beyond their initial service life. The company's lifetime warranty on heater elements — offered on both the Thermo-5 and Thermo-6 generations — signals a level of component confidence that translates directly into strong resale value. Parts availability and a global service network further support buyers who want the precision of Swiss-made temperature control technology at a used-equipment price point.
