Circulation chillers Variocool

Circulation chillers for variable use in laboratory, mini-plant and production for temperatures from -20 up to 40 °C

The LAUDA Variocool circulation chillers offer a broad performance spectrum for demanding temperature control tasks. The color TFT screen makes operation easy. A USB interface and an alarm contact are integrated as standard features. Additional interfaces are available as accessories. They are located in the front of the device, which means they are easy to access. The circulation chillers with their multitude of options are very well suited to a number of different applications. Optional pumps, for example, enable higher supply pressure. Optional heating units, which are adapted to the cooling capacity, enable the quick heating of the connected application when needed.
