Indoor Pool Climate Control & Ductwork Design & Installation
Effective climate control is critical to the long-term success of any indoor swimming pool. Without correctly designed air handling and ductwork systems, excessive humidity, condensation and chloramine build-up will quickly lead to corrosion, structural damage, poor air quality and an uncomfortable environment for bathers.

At Brookforge Limited, we design, supply, install, service and refurbish complete indoor pool climate control systems for:
- Private residential pools
- School and academy pools
- Hotel and spa facilities
- Health clubs and leisure centres
- Therapy and hydrotherapy pools
We provide fully integrated solutions — from initial heat load calculations through to ductwork fabrication, installation, commissioning and ongoing servicing.
Independent Specialists – Not Tied to One Manufacturer
We are completely independent and not tied to any single manufacturer.
We can service, repair, refurbish or replace systems from most leading pool ventilation brands, including:
- Calorex
- Heatstar
- Dantherm
- Recotherm
This means:
- We can offer honest, unbiased advice
- We recommend the most suitable system for the project — not the one we are obligated to sell
- We can replace units like-for-like where required
- We can upgrade to more efficient alternatives where appropriate
For schools and commercial clients in particular, like-for-like replacement is often the fastest and most cost-effective solution where ductwork and services are already configured around an existing unit.
Replacement, Upgrade or Repair?
We frequently undertake:
Reactive Repairs
- Fan motor replacements
- Heat exchanger repairs
- Control panel faults
- Refrigerant circuit issues
- Corrosion remediation
Like-for-Like Replacement
Where an existing unit has reached end-of-life, we can often replace it with a direct equivalent model from the same manufacturer to minimise disruption.
System Upgrades
Where energy efficiency, corrosion damage or poor performance are issues, we can upgrade to modern high-efficiency systems.
Modern units offer:
- Integrated heat pump technology
- High-efficiency heat recovery
- EC fan motors
- Reduced running costs
- Improved corrosion resistance
Ductwork Design & Installation

Correct duct design is just as important as the air handling unit itself.
We ensure:
- Supply air washes across glazing to prevent condensation
- Extraction removes chloramines from the breathing zone
- Corrosion-resistant materials are specified
- Balanced airflow throughout the pool hall
- Integration with ceiling design and architectural finishes
We also regularly replace corroded or undersized ductwork as part of refurbishment projects.
