Police Authority HVAC System
How DosaFil®-Duo and solid paste chemicals saved a brand new system from near failure whilst preventing disruption, building shutdown, and high remediation costs.
Project Details
| Client: | Police headquarters |
| Project type: | DosaFil-Duo® + solid chemicals |
The Problem
Poor system performance
- Brand new police head quarters
- Harmful levels of contaminants found in the closed, low temperature heating system (incorrect pH, suspended solids, and more)
- System had not been cleaned, treated or maintained sufficiently between installation and handover
- Danger of accelerated corrosion, blocked valves, and system failure
- Powerflushing would have required the opening of every valve on the system, all of which were behind wall panels – an extremely expensive and disruptive endeavour, potentially requiring large parts of the building to be shut down

The Solution
DosaFil® system installed
- DosaFil-Duo® was installed in less than a day
- Solid paste stick chemicals were added to the system
2
The Results
A cleaner, more efficient system
- DosaFil® cleaned the system online
- Optimised energy efficiency, performance and longevity
- Easy online system clean avoided significant capital expenditure or costly chemical cleaning and flushing
- System operation significantly improved
- Maintenance requirements have reduced to a level expected in a system of this type
- Permanent switch to safer solid chemicals
- Reduced water usage
