• Wear protective gloves.
• Please place appropriate warning signs in the vicinity of the device.
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.

Description

The Servimat is a pump-controlled pressure maintaining, make-up and
degassing station for heating and cooling water systems. The Servimat is
essentially a control unit with pump, vacuum spray pipe and at least one
expansion vessel. The expansion vessel is fitted with a membrane to divide the
vessel into an air space and a water space. preventing the ingress of atmospheric
oxygen into the expansion water.
