The super insulated exhaust, which allows the safe removal and extraction of hot exhaust fumes from an engine, will soon be withdrawn from Pyroban’s extensive line of explosion proof (ATEX) products.

Exhaust gases can often reach 600°C which could lead to the exhaust surface temperature becoming an ignition source. If a T3 (200°C) certified gas came into contact with the unprotected exhaust pipe it could be ignited and cause an explosion.

Removing the risk of explosion with Ex-SIT

In order to remove the risk of explosion, the innovative insulation technology ensures that the outer surface of the Ex-SIT pipe remains below the T3 (200°C) temperature threshold for the site, without the need to cool the internal exhaust gas temperature or application of traditional bulky lagging materials.

Pyroban insulation technology allows the exhaust gas to be transported with the external skin of the exhaust pipe remaining below the T3 temperature class. If a gas comes into contact with the exhaust pipe, the surface temperature is at a safe level and the gas will not be ignited.

Designed and constructed for any application

Pyroban Ex-SIT is a modular based system made up of standard length pipes and a range of fittings that enable you to construct a complete system to meet your specification. Ex-SIT is designed and constructed in a similar way to standard engine exhausts, making it easier for a user to design a system to fit their application.
