Refrigerated Baths

These baths are a complete refrigerated circulating system for closed circuit applications for temperature ranges from -35 to 100°C.

Two bath capacities are available, 7 litres (RB-5A) or 12 litres (RB-12A). Temperature control is by the thermoregulator giving four different combinations.

* OTBSoft Software

OTBSoft has been designed for use with OTB-8 Oil/Water Baths and the TU-20D controller on the refrigerated baths. It is a windows based programme that connects via an RS232 connection to your computer. Programmes can be created, saved and recalled at any time as well as running in real time mode.

Time, temperature and ramp rates can all be set up. Temperature can be set to two decimal places. Temperatures within the range of -35°C to 250°C can be programmed. Refrigeration units are available for connection to the system and can be controlled via the software.

A Refrigeration Control Pack is needed to turn the refrigeration unit "on/off" when used with the software.
