Metaloterm® UP

The Metaloterm®UP system is a modular twin wall flue system, made of stainless with an air gap insulation and sealing ring. Metaloterm®UP is suitable for high and low temperatures, condensing and non-condensing applications with flue gasses in positive or
negative pressure and it is even chimney fire resistant. Due to the special inner wall of AISI 904 it is more corrosion resistant. There for it is suitable for biomass fuelled applictions where the fuels are not free from aggressive acids. For example pellet fired stoves or central heating devices.

· Gas fired stoves
· Oil-fired appliances
· Industrial ventilation systems
· Air inlet or ventilation system
· Condensing heaters and boilers
· Pellet fired stoves 

· Universal applicable flue system
· Compatible with Metaloterm® ME and Metaloterm® MF
· Pressure-tight up to 200 Pa
· Inner wall from AISI 904
· Stress free thermal expansion
· Extremely low heat mass maintains draught and allows longer runs of installed flue
