Construction

Deltavent sectional lengths/fitting components are fabricated in a variety of diameters and lengths with continuously welded vertical seams. The Deltavent system also utilises four insulated/non-insulated annular variation options to provide a required minimum external case surface temperature. Inner liner coupler characteristics consist of male and female connection sockets complete with a 10mm 90° right angled flange formed at either end of all components. Deltavent joints shall be secured by clamping an externally fitted V-Band over the mating flanges of the adjoining components.

Diameter RANGE

This double-lined system is available as Deltavent 25 (with a 25mm insulating gap) or Deltavent 50 (with 50mm mineral wool insulation). There are also 75mm and 100mm annuli available on request.

Ovens & Bakery

Commercial bakery ovens are available in various types, each suited to specific production needs.

Biomass Heating System

Biomass heating systems generate heat from biomass. The systems may use direct combustion, gasification, combined heat and power (CHP), anaerobic digestion or aerobic digestion to produce heat.

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.

District Heating Systems

It used geothermal energy to provide heat for about 30 houses and started operation in the 14th century.

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.

Standby Generators

Automatic standby generator systems may be required by building codes for critical safety systems such as elevators in high-rise buildings, fire protection systems and standby lighting.

Diesel Generators

Some applications require the diesel generator to accept a high impact load, with minimal voltage and frequency deviations in the event of a power loss.

Chimney 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.
