TWIN WALL FLUE SYSTEM PLUS
The PLUS system is composed of twin wall elements with circular section suitable for outdoor use. It is supposed to be solely used for condensate boilers and its maximum operating temperature is 120°C.
The inner wall is manufactured in PPs, plastic polymer, while the outer wall is manufactured in stainless steel AISI 304 with BA shining finish and longitudinal plasma welding.
All PLUS elements have 10 mm of air insulation, a male-female socket and an EPDM seal. Locking bands (supplied on demand) ensure mechanical tightness. Their outer wall can be manufactured in copper or painted (R.A.L. range) stainless steel.
