Heating and cooling circulators

Huber offers two types of circulators, which are the CC models and KISS models. Both product ranges are classically constructed laboratory circulators with open baths. The company produces baths and circulators for heating applications of up to 300°C, as well as models for heating and cooling applications between -90 °C and 200°C.

Ministat is the smallest cooling and heating circulator in the world, and ideal for operation in fume hoods or system integration.

Bath and circulation thermostats are available for temperature control of externally connected operations with options such as samples and sensors for the thermostat bath, in addition to immersion and bridge circulators. Devices feature long-life bath vessels made out of high quality stainless steel with pump connections.

All models feature an over temperature and low level protection system, which meets safety class III/FL (DIN 12876) to ensure it is suitable for use with flammable fluids. It includes a powerful pressure suction pump for optimal heat transfer.

Hook-and bridge thermostats, polycarbonate or stainless steel baths and refrigeration and low refrigerated circulators are also available.

Recirculating and immersion coolers

Huber produces circulating chillers for environmentally friendly and economical cooling in laboratories. The company has more than 50 air and water cooled models with outputs ranging from 0.3kW to 50kW.

All chillers feature efficient energy management to maintain low operating costs and minimal water usage. The stainless steel chillers are a small, eco-friendly alternative to cooling with fresh water.

Controller technology for set temperatures

Huber provides the Pilot ONE and KISS/OLÉ controllers for a range of functionality to suit different temperature control requirements, budgets and applications. The KISS/OLÉ controllers are ideal for basic functionality, while Pilot ONE features more extensive features. Pilot ONE offer additional upgrades with e-grades, which allow software to be updated using a unit specific, upgrade code.

Huber provides flexible solutions for heating and cooling in test stands, machines, industrial and production plants, as well as analytical systems.

Customised temperature control system

Huber adapts temperature control solutions to clients’ needs and provides personalised advice. The company offers suitable solution approaches and show reference projects with comparable requirements. Other specialist areas for temperature control products include integration into the plant such as a heating and cooling plant in test stands, machines, industrial and production plants, as well as medical devices and analytical systems.
