Heated Filter

Heated filter

Primary conditions set to the stationary gas measurement systems are trouble-free operation and long maintenance intervals.
As the analysers very often work in harsh environments: toxic, caustic and much polluted, the proper conditioning of the gas sample is the top priority requirement.
For such applications madur's heated gas filter is an answer that provides proper preparation of the sample and protects fragile and sophisticated components of the gas analyser.
Heated filter was designed as a part of entire sampling system, to work with madur's stationary gas probe and heated hose. But, thanks to universal couplings and independent power supply filter can work stand-alone with equal success.

Main features

  • Water present in fumes + gaseous components react and create acids, very often caustic ones. To prevent water condensation and in consequence hindering creation of acids, the gas temperature must be kept above its dew point. Thanks to filter's heating this condition is met. Keeping the gas temperature above its dew point not only prevents creation of harmful acids, but most importantly, enables undisturbed measurement of gases that easily reacts with water.
  • Filter's casing allows easy access to its insert (that is washable, made of sintered stainless steel). Simultaneously with accessing the insert, maintenance crew has possibility to remove dust / soot residues that deposit inside it.
  • Cooperation with madur sampling system elements (heated hose, stationary probe pipe)
  • Cooperation with external systems - thanks to filter's universal connection ends - stainless steel pipe, OD=10mm - that can be clamped with e.g. Swagelok or DK-Lok couplers

Hereby tool helps to configure, in few simple steps, ready to measure analyser. It allows to select main structural components, like gas dryer, gas sensors, etc. Some elements, like probe pipes are to be selected separately. This mini-configurator, generates a list of madur codes that identifies the selected configuration. Customer may add own comments and requests. Device configuration has to be verified by pressing the Refresh button in the Order Summary section. Order summary can be send to our sale engineers for validation and in order to obtain price offer.
