Construction

Single-Skin Deltavent sections/fittings are fabricated in a variety of diameters and lengths with a continuously welded vertical seam. The (coupler) characteristics consist of male and female connection sockets complete with a 10mm 90° right angled flange formed at either end of all components.
Single-Skin Deltavent joints shall be secured by clamping an externally fitted V-Band over the mating flanges of the adjoining components. Sealant, available from A1 Flue Systems, should be applied to the inside profile of the V-Band and to both flange faces before installation.

Combined Heat & Power

Combined heat and power (CHP), also known as cogeneration, is a highly efficient power plant that generates heat and power simultaneously.

Commercial Ventilation

A1 Flue Systems is a UK specialist in commercial ventilation systems for buildings of all sizes, from small office blocks to schools, hospitals and large skyscrapers.

Condensing Boilers

Condensing boilers capture the exhaust condensation of the burning gas that would otherwise be wasted through the flue.

Fan Dilution Systems

Fan dilution systems were originally developed in order to discharge the flue products from gas-fired appliances at a CO2 level of 1% or less.

Chimneys Liners

Most commercial chimneys were constructed without a liner system, although some were originally built better than others given time they all tend to breakdown over the years.
