Project and commissioning managers are still often asked to flush to drain by companies who are unaware of the newer and far superior way of cleaning and preparing closed water systems: Hydrosphere’s CPC.
So here’s five reasons you can give them to make the case for a method that is better for their purse and the planet:
1. Faster & More Cost-Effective
Traditional flushing involves multiple flushes to drain and chemical cycles, and introduces chemical and microbiological uncertainty. Hydrosphere’s CPC process uses pre-treated water, and systems are cleaned through high-efficiency filtration. This reduces the number of stages involved and means projects are completed 50% faster, labour costs are halved and certainty is delivered.
2. No Effluent Licence or Disposal Hassle
Hydrosphere’s process is effluent-free. No contaminated discharge, no licence requirements, and no disposal logistics. This means fewer compliance headaches and lower costs.
3. Better Performance, Longer Lifespan
By conditioning the system correctly from the first fill and removing debris and corrosion by high-flow filtration, Hydrosphere’s process delivers cleaner systems that perform better and last longer. This significantly reduces repair and maintenance costs.
4. Significantly Lower Environmental Impact
Flushing to drain uses up to 30 system volumes of water, which is discharged as chemical effluent. Hydrosphere’s process only uses the water that’s needed to fill the system and completely eliminates polluting discharge. This achieves a major sustainability advantage on all projects.
5. Simpler Set-Up, More Reliable Results
Hydrosphere’s closed-loop method keeps treated water within the system, providing consistent protection while contaminants are filtered. This delivers dependable, standards-compliant results.
If you’re still flushing to drain, it’s not just water you’re wasting.
Hydrosphere is the most environmentally responsible, easy to use and less damaging replacement for the traditional process of system pre-commission filling and chemical flushing of heating and cooling systems.
