Diaphragm expansion vessel (MAG)
To avoid pressure fluctuations during standstill
because of temperature changes, diaphragm
expansion vessels filled with nitrogen (moisture
neutral) must be integrated in the system.
The preliminary pressure must be set on the
system; an increase in volume or, in the event of
the realisation of a cooling-heating system, the
installation of another diaphragm expansion vessel
may be necessary.
If there is already a diaphragm expansion vessel in
the unit, this is only designed for the medium
volume of the unit itself. An additional diaphragm
expansion vessel is always required for the
hydraulic system provided by the customer.
Fill and drain connection
A connection should be provided in an area safe
from frost for the draining of pipe lines (especially if
water is used as a medium). Applicable local dis-
posal ordinances must be observed if glycol is
used.
Dirt trap
A rinsable dirt trap must be installed upstream from
the unit intake. Shut-off valves should be installed
upstream and downstream of the dirt trap in order
to be able to isolate this during maintenance and
cleaning work. The mesh width of the sieve insert
shall not exceed 0.6 mm.
NOTICE!
Improperly installed or missing dirt traps can
cause fouling of the plate heat exchanger.
NOTICE!
The installation of a dirt trap in the unit's return
is necessary for the safety of the unit. If the
technical assistance commissioning of the
chiller is to be carried out by REMKO GmbH &
Co. KG or their partner company, the prior
installation of a dirt trap is essential.
Compensators
Compensators are used to connect lines to the unit
to prevent vibration in the chiller from transmitting
to other system components.

Safety valves
Safety valves limit excess operating pressure due
to excess warming or overfilling of the operating
medium. The valve outlet requires unobstructed
draining into a drain line. Applicable local disposal
ordinances must be observed if glycol is used. The
unit's standard equipment includes one safety
valve (for unit configuration with pump).
