Revision 1.0.7 October 2018
INTENDED USE OF THE
EQUIPMENT
Water vapor Cryochiller is a device that improves the performance of vacuum
pumping due to the efficient trapping of water vapor in the chamber.
Classically a Cryochiller is used with an evaporative surface (Meissner/cryo-
coil), which is located within the vacuum chamber. When in this configuration
a Telemark Cryochiller is an ultrahigh performance vacuum pump capable of
pumping water vapor and other condensable gases at speeds far in excess of
conventional vacuum pumps.
A Telemark Cryochiller couples speed with a sophisticated computer control
package which includes a simple and adaptable user interface with isolated
inputs/outputs and Ethernet comms package as standard. RS232 and RS485
serial communication options are available.
The ranges of tasks to which your Cryochiller can be applied are not limited to
pumping water vapor in vacuum. Many are used as substrate coolers (chuck
coolers) or other applications where a continuous level of high power cooling
in the range –100 to –150
o
c is required.
STANDARDS
The device is compatible in terms of electromagnetic compatibility and safety
standards. Applicable standards:
EMC: DIRECTIVE 2014/30/UE - STANDARD EN 61326-1:2013
LVD: DIRECTIVE 2014/35/EU - STANDARD EN 61010-1:2011
And applicable causes of the standard: EN 378-2:2008

2.2 System Pressure
The unit is shipped fully charged. See Tables 1 and 2 (Section 1
“Specifications”) above for shipping pressure range of each model. The exact
shipping pressure is noted on the packing list. A pressure gauge is mounted
behind the front panel or to the right hand side of the unit. The static pressure
may vary by up to +/- 16 psi due to changes in the ambient temperature.

2.3 Location
The unit should be placed and a clean level floor and positioned to minimise
the length of the refrigeration lines. It is also important that the lines are well
supported and are manufactured from annealed copper tubing allowing for
thermal expansion and vibration. The units should be placed at least 3”
(80mm) away from the nearest obstructions to allow for sufficient air flow to
the unit.

2.4 Panel Removal.
 Remove the front panel to gain access to “hand valve” gas box. Remove the
6 (or 8 screws depending upon model) and remove the front panel exposing
the hand valves. Remove the right hand side panel where the isolator handle
is located.

Note: the panel can only be removed with the isolator
switch in the “OFF” position

2.5 Water Connections
The advanced design of the unit means it is capable of operating over a
wide range of water temperatures. While Liquid Line temperature (LT on the
display) is preset to 40°C maximum, there is littl e loss of performance with
water (outlet – this is not displayed on the unit) temperatures as high as 35
°
C.
Higher water temperatures result in a slight loss of capacity while water colder
than 15°C will slow the systems response and lead to undue condensation on
water lines.
In-house re-circulating water-cooling system is required. Water must be free
from chlorides and sufficiently soft to prevent the build up of lime scale (0.1
M
 resistivity). Ensure that the water is clean and free from any clogging
debris. The Ph value should be between 6.5 and 8. The water inlet and
outlet pipe-work needs to have a minimum diameter of ¾ inch (15mm). The
use of a suitable biocide can be beneficial when used in closed loop water
systems.
Connect the water lines to the unit ensuring the correct orientation of the
water lines (see fig 3 above). Turn on water flow and ensure no leakage is
present at connectors. Open the cabinet and check visually for water
leaks inside the cabinet.
Water temperature below ambient temperature, may cause condensation.
Additional insulation of the internal water lines may be required if the cooling
water temperature is low and the ambient humidity is high.
The graph (fig 4) below indicates the cooling water flow required at varying
inlet temperatures. As a practical limit, a flow rate of 30 l/min is
approximately equivalent to a 15psi (1bar) pressure drop across the Unit.
