Turning HVAC waste water into
cleaning solutions.
HygenLoop captures cooling tower blowdown water, treats it, and converts
it into controlled cleaning and disinfectant solutions for commercial buildings.
An untapped water resource.
Water-cooled HVAC systems routinely discharge "blowdown water" as waste to maintain efficiency. HygenLoop integrates with existing waste pipes to transform this clean, mineral-rich stream into a managed cleaning resource without interrupting your HVAC system or requiring plant shutdown.
The 5-step recovery process.
-
Blowdown Diversion
Water is diverted from the HVAC discharge pipe before entering the building drainage system.
-
Water Conditioning
Recovered water undergoes cooling, filtration, and mineral stabilisation to prepare it for safe operational use.
-
Building Distribution
Conditioned water is routed through riser infrastructure directly to cleaning cupboards and service areas.
-
System Integration
The supply connects to HygenLoop for controlled dosing or ozone-based disinfectant generation.
-
Controlled Dispensing
Cleaning teams access regulated volumes of solution, ensuring consistent dilution and reduced overuse.
Estimated blowdown recovery potential.
Water-cooled HVAC systems discharge substantial volumes of blowdown water during normal operation.
HygenLoop captures and conditions this water, converting it into reusable cleaning solutions that reduce water waste while supporting healthier buildings.
This table shows typical cooling capacities and the volumes of blowdown water that may be available for recovery. In many buildings, this supply alone can meet all daily cleaning water requirements.
