Cascade System

Waste gas systems of condensing boilers which are the heating devices of our era are made with PROTEK - PROALU - PROPAS - PROGAL chimney systems. The only difference between this system and the other systems is that it is designed with seal to operate with the P1 pressure condition. Thanks to the seal between the two modules, the impermeability of system is enabled under 200 Pa pressure within the limits stated in the CE declarations. 9 pieces of devices, whether wall or floor type, can be connected as a cascade chimney through a collector in line with regulations, and thus are free from multiple chimney images.
