Ducting Smoke

Smoke from most Concept systems can be ducted if required, using the inherent velocity of smoke produced by the systems, or incorporating fan assistance if rapid distribution of smoke is required.

Generally a small amount of deposition should be expected in ducting systems as the smoke particles are being artificially restricted, and cannot separate and spread out as they would in free air. For best results the ducting should be as short and straight as possible, with as smooth a bore as practical, so that frictional losses within the duct are kept to a minimum.

Smoke can be ducted at very low output, (as illustrated) to highlight for example laminar flow, or at high output if smoke logging areas for the purpose of training or leak testing.

For larger volumes where dense smoke logging is required, we would normally recommend the use of fan assisted distribution systems. These allow ducting runs of typically 30 - 40m.

This allows for several rooms or compartments to be smoke logged simultaneously if required, distributing the smoke typically through smooth bore PVCu pipework into the respective areas.

Fan assistance can greatly improve the effectiveness of ducted systems.

Concept have considerable expertise in the application of ducted smoke, as calculating the pressure and flow performance of a proposed ducted system is critical in ensuring an effective result. Every application is different however, and the pressure required to overcome frictional resistances within the ducting system, and hence the fan specification, depends on many criteria.

If you have an application which calls for the ducting of smoke then please contact us. We would be pleased to assist you in specifying the correct ducting and fan combination.

Testimonials

Graham Law - Head of Technical Services

"With our Spirit 900 having been in heavy use for two years we found ourselves requiring a rapid full service to fulfill a critical last minute schedule.

With less than 24 hours notice I was invited to the factory workshop where Kerry who was waiting for my arrival & had dropped everything to assist me, stripped down and serviced the unit whilst providing hands on training for myself.

Customer care like this is well above and beyond the normal and a very rare thing these days. 

Well done chaps from a happy customer."
