For the most part Coned-housings are used where the local circumstances do not allow the usage of slide-in-housings or chambers.  
The cones are designed to achieve an ideal inflation and deflation. The pipe connections usually are flanged fittings so the entire catalyst can easily be removed for maintenance or exchange.
Generally the housings are available in every size with different gauge-connections and clamping elements.
The housings are suitable for all types of catalysts and designed in size and form to fit every individual space condition.
The Catalyst Matrix is on stock in the standard depth of 90, 120, and 150 mm. Other sizes are available on request.
