Application
Heated M&C sample conditioning systems are
used where increased and constant operating
temperatures are necessary for the analysis of
gases or liquids.
The large M&C product range of heatable
components, in connection with the heated
PAS-... protective housing, allows you to solve
problems specific to your applications.
Description
The conditioning components are housed
in the protective cabinet (wall mounting)
made of stainless steel, which is heat
insulated on all sides. The front door with
its single-knob lock enables easy access
to the accommodated components.
An observation window made of triple safety
glass is available as an option.
The heating of the cabinet is selectable within
the range of 20 to 200 °C. An exact, electronic
control unit keeps the temperature
constant at ±1 °C. The temperature is displayed
digitally. Two monitoring devices (temperature
selection
control and temperature
limiter), which are fitted additionally, ensure
safe operation. In order to distribute the temperature,
a ventilator is fitted additionally
into
models of size PAS-400 and above.
Depending on individual requirements the
following components can be installed:
• Filters
• Solenoid valves
• Valves, manually or pneumatically operated
• Ball valves, manually or pneumatically
operated
• Flowmeters with a needle valve and a
monostable flow control
• Pumps (pump head inside heated part,
motor outside)
• Customized parts
Suitable bushings into the heated interior are
provided for the heated sample lines.
Designs with European standard explosionproof
heating up to 120 °C operating temperature
or with steam heating as well as larger
cabinets are available on request.
