Compact refrigeration circulating oil bath

The smallest refrigeration circulating oil bath. The utility model has the advantages of compact structure and small floor area, and can be placed in the fume hood of the laboratory. Although small in size, it has powerful functions. It is widely used in photometer, refractometer, viscometer, distiller, reactor, intermediate factory, etc.

Mainly used for external circulation – small volume containers can be placed in the open tank for

constant temperature. The flow rate of powerful pressure pump and absorption pump can be adjusted to ensure the best circulation. The optional pressure sensor can adjust the pressure to prevent damage to the reaction kettle or other fragile vessels caused by excessive pump pressure. Control panel, color TFT display, simple operation wizard. The analog interface conforms to NAMUR standard, and the optional module can realize the integration of remote control and automatic control system.

The new multi touch controller has a 5.7-inch touch screen, graphical user interface and navigation

menu, with 11 languages to choose from. All important operating parameters and temperature values are neatly displayed on the touch screen. The new Favorites menu, one click operation and technical terms make it very convenient for users to operate, just like using smart phones. Integrated USB and Ethernet ports can be connected with computers and networks, for example, for remote control and data transmission.
