Indoor Pool Ventilation & Dehumidifier Upgrades – SPECS by ADWAY

​Indoor swimming pools need reliable humidity control and ventilation to protect the building and keep running costs under control.

SPECS by ADWAY is our specialist service for upgrading and rebuilding indoor pool environmental control systems. Our directors are former Calorex engineers with over 60 years of combined experience.

We regularly carry out rebuilds and upgrades on systems across Essex.

What is SPECS?

SPECS is our custom retrofit and rebuild service for indoor pool heating, ventilation and dehumidification systems.

Instead of replacing the entire unit, we improve the existing plant so it runs more efficiently and reliably. This is often more cost-effective than a full replacement while delivering better performance.

We commonly work on:

  • Calorex Delta systems

  • Calorex Variheat systems

  • Other indoor pool air handling and dehumidifier units
