CAUTION
Risk of injury due to pressurised liquid
If installation, removal or maintenance work is not carried out correctly, there is
a risk of burns and other injuries at the connection points, if pressurised hot
water or hot steam suddenly escapes.
• Ensure proper installation, removal or maintenance work.
• Ensure that the system is de-pressurised before performing installation,
removal or maintenance work at the connection points.
 Note!
Equipment parts with a safety function in respect of water-side pressure
limiting according to the Pressure Equipment Directive 2014/68/EU and
temperature limiting according to the Pressure Equipment Directive
2014/68/EU are not supplied.
The operator is responsible for on-site provision of water-side pressure
and temperature protection.
 Note!
When installing the on-site safety valve, the operator must ensure that
there is no danger during blow-off.
4 Description of the device
4.1 Description
The Reflexomat is a compressor-controlled pressure maintenance system. The
main applications are glycol circuits with up to 50% glycol fraction, heating circuits
and cooling circuits.
• Vessel size nominal volumes:
• 200l
• 300l
• 400l
• 500l
• 600l
• The control unit is factory-installed on the expansion vessel.
• All electric and air connections between control unit and primary vessel are
pre-installed.

1 Make-up with water e.g. using Servitec S
2 Control unit
3 Primary vessel as expansion vessel
WC Make-up line
PIS Pressure sensor
SV Safety valve
PV Solenoid valve with silencer
LIS Weight measuring cell for level measurement
EC Expansion line
Expansion vessel
A butyl bladder divides the interior of the vessel into an air space and a water
space. This prevents the ingress of atmospheric oxygen into the expansion water.
The primary vessel is connected to the air side control unit and connected
hydraulically to the system circuit. Pressure relief is provided on the air side by the
vessel's "SV" safety valve.
Control unit
The control unit comprises a compressor and the "Reflex Control Smart" controller.
Via the primary vessel, the pressure is measured using the "PIS" pressure sensor
and the water level using the "LIS" weight measuring cell and the values are then
displayed on the control unit and via the app,  9 "Controller",  27.
