General design

The immersion coolers ETK 30 und ETK 50 have air-cooled fully hermeticla encased
condensing units which are completely maintenance-free.
The cooling coil maide from stainless steel is connected with the condensing unit by an
insulated flexible metal tube of 1,5m length. The electronic temperature controller of
Immersion Cooler ETK 50 controls a solenoid valve in the cooling circuit. The temperature
probe (Pt 100) is mounted in the cooling coil.
ETK 30 has no temperature control.

Unpacking and Set-up

The careful packing largely protects from damages during transit. If, however, the
Immersion Coolers is damaged inform the forwarding agent or the post office.

Operating Instruction

4.1 Set-up

The condenser of the cooling unit is air-cooled. Fresh air is sucked at the front of the
instrument and the warmed air is removed at the back. In order to guarantee good air
circulation the venting slots must be free. Take care that no extremely warm air is sucked.
Do not place the instrument near a heater.
Increased ambient temperature results in reduced capacity. In case of an excessive
overloading of the compressor, caused by too high refrigerant pressure or too high ambient
temperature, the instrument is switched off automatically by a bimetyl switch (KLIXON). It is
switched on automatically as soon as the compressor has cooled down.

Cooling of Consuming Devices

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.
