Performance Characteristics

Cooling bath thermostats with insulated cooling baths are an economic solution for thermoregulation of objects directly in the thermostat bath. The units are therefore suitable for a number of typical heating and cooling tasks such as sample temperature control, materials testing, quality control, analyses, etc. Cooling circulator operates with natural refrigerants and are therefore offer an environmentally friendly solution to temperature control. In addition, cooling circulators are fitted with automatic refrigeration capacity adjustment, reducing energy consumption and waste heat down to the absolute essential. With low level protection and adjustable over heating protection the units fulfil the requirements of Safety Class III/FL according to DIN 12876. The thermostats can also be used for externally attached applications using the pump connections at the rear.

Please take further technical information as well as information about the scope of delivery, accessories and peripheral devices from the PDF data sheet. In cases of doubt the details given in there apply. If nothing to the contrary is quoted then the performance data referred is at an ambient temperature of 20°C.

Please observe the notes on installation and/or the space requirements of our products.

The following voltage and frequency tolerances apply based on EN60034-1:
Voltage +/- 5% for a frequency tolerance at the same time of +/- 2%

Examples to illustrate this: Not permissible, for example. is -5% on the voltage and +2% on the frequency. Permissible, on the other hand, are tolerances of -5% on the voltage and -2% on the frequency.

We reserve the right to make technical changes and correct errors. Illustrations can deviate from the original.
