Temperature control units

Temperature control units are frequently used in the plastics and rubber industries. In these applications, they preheat the tools to operating temperature and dissipate the heat generated by the material during series production, thus avoiding overheating of the tool and damage to the product. Further application areas are in the chemical and pharmaceutical industries, in the food and packaging industries, metalworking or wood processing.

A plastics machine frequently runs in continuous operation (24/7). The safe operation relies, in a large part, on the quality of the temperature control.

Temperature control units have an external connection to a circuit, such as in the temperature control of an injection moulding tool in the plastics industry, and they are available as immersion baths, such as those used in laboratories or for quality assurance. The designs stretch from standard series production instruments through to project-designed temperature control plants (frequently multi-circuit systems) for production processes, for which large volumes of heat are required and possibly large quantities of heat must be removed.

A temperature control unit consists of the following main components:

• Vessel with heater and heat exchanger
• Recirculation pump
• Temperature controllers
