DELTAVENT US

TWIN-WALL FLUE SYSTEMS

Deltavent US high pressure twin-wall flue system that is used in in both high and very low temperature installations where the reduction of heat / cold transfer from the emission of gases inside a flue to the external environment is required.

Construction

Ultraseal sectional lengths/fitting components are fabricated in a variety of diameters and lengths with continuously welded vertical seams. The Ultraseal system also utilises four insulated/non-insulated annular variation options to ensure the required maximum external case surface temperature is not exceeded. Inner liner coupler characteristics consist of male and female connection sockets complete with a 6mm x 30mm angled flange formed at either end of all components. Ultraseal joints shall be secured by a 30mm flange of the adjoining components.

Diameter RANGE

This double-lined system is available as Deltavent 50 (with a 50mm insulating gap)

There are also 75mm and 100mm annuli available on request.

Combined Heat & Power

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

Cryogen Quench Pipe

We have decades of experience in the design, manufacture and installation of flues, exhausts, flue dilution and extract systems. This also includes Quench pipes for MRI machines.

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.
