TEC-LAS-PP
Pressure-tight, concentric exhaust system with exhaust gas-carrying inner tube made of polypropylene and an outer pipe made of high-quality stainless steel for condensing boilers or combined heat and power plants. This exhaust system uses the annular gap between the inner and outer pipes for the supply air and is suitable for flue gas temperatures up to 120 ° C . TEC-LAS-PP is available in diameters 60/100 mm, 80/125 mm, 100/150 mm and 110/160 mm.

TEC-LAS-PP-VL
Pressure-tight, concentric exhaust pipe for indoor installation. The annular gap between the exhaust-gas-conducting inner pipe made of polypropylene and an electrogalvanized outer pipe is used to supply air to condensing boilers or combined heat and power plants, suitable for flue gas temperatures up to 120 ° C. TEC-LAS-PP-VL is usually used as a connecting line in combination with the TEC-LAS-PP or TEC-PP (relining) or when using the fireplace as a roof heating center. Available diameter combinations are 60/100 mm, 80/125 mm, 100/150 mm and 110/160 mm.

TEC-LAS-DECO
A concentric exhaust system with stainless steel inner pipe and pressure-tight stainless steel outer pipe for the connection to modern decorative gas fireplaces, which draws the combustion air from outside through the annular gap between the inner and outer pipes. A silicon seal prevents possible mixing of room air with combustion air. The special affixing of the seal in the outer pipe allows high exhaust gas temperatures in the inner tube up to 600 ° C. TEC-LAS-DECO can be ordered in diameters 100/150 mm and 130/200 mm.
