Leisure Centres & Aquatic Facilities
Ventilation solutions
for pool halls.
Leisure centre ventilation, and pool hall AHUs in particular, is a specialist application. The environment accelerates component failure, demands specific material selection, and requires correct humidity control to prevent structural damage.

The environment
Why Pool Halls Destroy
Standard HVAC Plant.
Pool hall air contains elevated chloramine concentrations, a by-product of chlorine disinfection and human contact. Chloramines are highly corrosive to steel, aluminium, copper, and most standard coatings. Standard commercial AHU components have a significantly shortened service life when exposed to this environment continuously.
Humidity control
Pool hall AHUs must maintain precise humidity, too high causes structural damage and user discomfort; too low increases evaporation and chemical cost. Both are an AHU performance issue.
Air volume and distribution
Correct air change rates prevent chloramine build-up at breathing level. Poor distribution creates dead zones, typically identified by persistent smell or patron discomfort in specific pool positions.
Heat recovery
Pool halls have significant heat recovery potential from warm exhaust air. Run-around coil and other heat recovery configurations can substantially reduce the heating energy required to condition pool hall supply air.
What we find on site
Common Failure Points
in Leisure Centre AHUs.
Pool hall AHU failure rarely presents suddenly. It is usually a progressive deterioration, components failing earlier than expected, performance dropping, energy costs rising. These are the most common findings when we survey leisure centre plant.
Corroded belt-driven fans
Belt-driven fans fail significantly faster in pool environments. Belt slip, bearing corrosion, and pulley damage are common, combined with high maintenance frequency and unplanned shutdowns.
Coil corrosion and fouling
Heating and heat recovery coils exposed to chloramine-laden air corrode progressively. Performance drops, energy cost rises, and eventual failure causes complete loss of humidity control.
Casing and panel corrosion
Standard galvanised steel AHU casings corrode in pool environments. Structural integrity degrades over time, a refurbishment must address the casing as well as the components.
No variable speed control
Pool hall AHUs should modulate speed based on humidity and occupancy. Fixed-speed operation wastes energy and is unable to respond to changing conditions, a significant operating cost issue.
Humidity control drift
Humidity setpoints drifting over time due to degraded sensors, failed actuators, or untuned controls, leading to humidity too high for structural safety or too low for operational economy.
No BMS visibility
Standalone controls with no fault logging mean problems go undetected until users complain or pool management observe structural symptoms, condensation, surface moisture, or persistent chloramine odour.
Energy opportunity
EC Fans Are Particularly
Suited to Pool Halls.
Leisure centre AHUs often run 16–24 hours a day. The energy consumed by fixed-speed belt-driven fans in this environment is substantial, and the energy saving from upgrading to EC direct-drive is among the most significant achievable in a building of this type.

Pool Hall AHU Troubleshooting & Survey, Marriott
Relevant if your project involves:
- Your pool hall AHU is failing to reach target temperature or humidity
- The unit was recently installed or maintained but is still underperforming
- You want an independent assessment before committing to replacement
AHU installed three years prior was only reaching 24°C against a 31°C target. Full survey identified ductwork leaks, diffuser inadequacy, and control issues. Rectification programme defined.

Relevant if your project involves:
- Belt-driven fans in a pool hall or humid environment have failed or are near failure
- Humidity and temperature control has been lost or is unreliable
- You want to extend AHU life without a full casing replacement
Two Ziehl-Abegg GR561 EC fans installed within the existing casing after catastrophic belt-drive failure. Humidity and temperature control restored. Belt maintenance eliminated.

Relevant if: You've been advised to replace AHUs that appear structurally sound, Controls are failing but the mechanical structure of the unit is in good condition, You want an independent assessment before committing to capital expenditure
Leisure · Ringwood
Controller Upgrade: £100k AHU Replacement Avoided
Relevant if your project involves:
- You've been advised to replace AHUs that appear structurally sound
- Controls are failing but the mechanical structure of the unit is in good condition
- You want an independent assessment before committing to capital expenditure
External consultants recommended full replacement at over £100k. Root cause was failing controls. Two Trend controllers installed. Both units now fully operational at a fraction of the cost.
Common questions
Frequently Asked Questions
Yes. Pool hall AHUs operate under specific humidity, temperature, and air volume requirements that differ significantly from standard commercial HVAC. We specify and install equipment appropriate to the environment, not standard commercial units adapted to cope.
Chloramine-laden air is highly corrosive to standard steel and aluminium components. Belt-driven fans with standard bearings fail significantly faster in pool halls than in commercial environments. Coils and casing panels are similarly at risk without appropriate material specification.
In most cases, yes. Pool halls have defined maintenance windows, typically overnight or early morning. We plan works to fit those windows and assess temporary ventilation requirements before any shutdown is agreed.
Yes, and they are particularly beneficial in leisure centres. EC fans operating at variable speed in humid environments outperform belt-driven fans on reliability and energy performance. The absence of belts removes a significant source of maintenance in a corrosive environment.
Yes. We source and specify epoxy-coated coils, stainless steel casings, and corrosion-resistant fan assemblies appropriate for pool environments. This is a standard part of our specification process for these buildings.
Yes. Many leisure centres are local authority operated or managed under PFI/FM contracts. We work within public sector procurement frameworks and understand the approval processes and documentation requirements involved.
