Swimming Pool Ductwork — Built for the Harshest Room in the Building
A pool hall is one of the most aggressive environments ductwork ever faces: air at 28–30°C, humidity near 60%, and chloramines that attack ordinary steel wherever condensation forms. We manufacture swimming pool ductwork with that environment in mind — corrosion-aware material choices, fully sealed seams, and layouts that manage condensation rather than collect it.
Why pool halls destroy ordinary ductwork
Warm saturated air condenses on cooler duct surfaces, and that condensate carries chloramines — the aggressive by-products of pool water treatment — which attack zinc coatings at cut edges and joints first. The answer is specification, not luck: the right material or coating for each part of the system, sealed construction, and a layout that lets condensation drain.
What we supply for pool projects
- Supply and extract ductwork for pool hall air distribution
- Connections and plenums for pool dehumidification units
- Corrosion-resistant material and coating options to suit the specification
- Changing room, plant room and ancillary area ventilation ductwork
Getting the specification right first
The most expensive pool ductwork is the system you have to replace. Tell us about the pool, the water treatment regime and the air handling design, and we'll help confirm materials and construction before anything is fabricated — or call 07710 984 957.
Frequently asked questions
Can you use standard galvanised ductwork above a swimming pool?
It depends on the environment and the specification. In well-controlled halls with good humidity management, protected galvanised systems have been used, but chloraminated condensation attacks zinc coatings over time. Many pool projects specify additional coatings or alternative materials — we'll advise based on your project rather than a one-size-fits-all answer.
What makes pool hall air so corrosive?
Chloramines — compounds formed as pool chlorine reacts with organic matter — are carried in the warm, humid air and concentrate wherever condensation forms. On ductwork, that means cut edges, joints and any cold surface, which is why sealed construction and condensation management matter as much as the base material.
Do you work with pool dehumidification systems?
Yes — pool halls are usually served by dedicated dehumidification air handling plant, and we fabricate the connecting ductwork, plenums and distribution to suit the unit and the hall layout.
How do I price ductwork for a pool project?
Send your drawings and specification through the contact page, including anything you have on the pool type and air handling design, and we'll come back with a proposal — or call 07710 984 957 to discuss the project first.
