Circulation baths

For each temperature range

Some applications need heating or cooling by circulation of an external liquid. 
A circulation bath is a closed or open container that contains a liquid that is conditioned to a specific temperature. This liquid is then circulated to an application to transfer heat. There are different types of circulation baths depending on the temperature range and the technology used.

A recirculating cooler is a kind of  compact semi-closed chiller/cryostat that contains a thermal liquid (mainly water or a water-glycol mixture). The aim is to circulate the liquid in a closed circuit and to remove heat out of the application by circulating the chilled liquid with the help of a circulation pump via a heat exchanger. They have been designed to replace tap water cooling solutions and to avoid spoiling it. They are available in different cooling power versions and optionally with an heater. Focus is on the cooling power and not on the accuracy-stability of the temperature. Typical applications:  Cooling down the condenser of rotary evaporators or Soxhlet extraction systems.

Heating circulators are open bath systems (eventually with cover) that contain a thermal liquid (mainly water or thermal oil). The heating circulator consist of a heater, a pump and a temperature sensor to allow a precise temperature control in a temperature range going from room temperature up to +300°C. They have been designed for internal bath applications or external applications (ex. temperature control of reactors). With an external temperature sensor the control precision in external application can be improved. Temperature profiles can be programmed to adjust the temperature automatically over time. Via an USB, RS232, RS485, Ethernet or Modbus port it is possible to connect the heating circulator to a logging software.

Refrigerated circulators are open bath systems (eventually with cover) that contain a thermal liquid (mainly water, water-glycol or thermal oil). The refrigerated circulators consist of a heater, a cooling coil cooled via environmentally friendly natural refrigerants, a pump and a temperature sensor to allow a precise temperature control from -95°C to +300°C. They have been designed for internal bath applications or external applications (ex. temperature control of reactors). With an external temperature sensor the control precision in external application can be improved. Temperature profiles can be programmed to adjust the temperature automatically over time. Via an USB, RS232, RS485, Ethernet or Modbus port it is possible to connect the heating circulator to a logging software.

Highly dynamic temperature control systems are very compact closed bath systems that contain a thermal liquid (mainly thermal oil). The highly dynamic temperature control systems consist of a heater, a cooling coil cooled via environmentally friendly natural refrigerants, a magnetic coupled motor-pump and a temperature sensor to allow a precise temperature control from -93 to +250°C. Equipped with a colour touchscreen a user friendly and intuitive control is possible. They have been designed for exclusive external applications (ex. temperature control of reactors). The closed bath system allows the control system to heat up the thermal liquid far above its flashpoint allowing to cover a very broad temperature range without the need to change the thermal liquid. No contact with the environment avoids also the fast oxidation and aging of the thermal oil. No oil fumes will fill the lab thanks to this design. The very small internal bath allows very quick reaction times. With an external temperature sensor the control precision in external application can be improved. Temperature profiles can be programmed to adjust the temperature automatically over time. Via an USB, RS232, RS485, Ethernet or Modbus port it is possible to connect the heating circulator to a logging software.
