Maximum cooling capacity is only obtained with completely immersed cooling coil. During operation the bending radius must not be smaller than 150mm ETK 50: Adjust the desired temperature. ETK 30 has no temperature control. Switch on the instrument at the mains switch (green lamp goes on).
By simple suspending of the cooling coil any bath contents can be cooled. In this way Thermostats or other baths to be tempered can be operated also below ambient temperature. It is possible to obtain operating temperatures to –30°C (ETK 30) and –50°C (ETK 50) depending on size and insulation of the baths concerned.
Use bath liquid with a lower freezing point (see leaflet "LAUDA bath liquids"). The bending radius of the flexible tube must not be smaller than 150mm. Otherwise the tube might break.
100°C. However it is possible that at higher temperatures the KLIXON switches of the compressor several times. Maintenance LAUDA Immersion Coolers are designed for coninuous operation and do not require maintenance routine. 8.1 Note on repair and disposal The refrigeration circuit is filled with a CFC-free refrigerant.
