Closed System Treatment
Precommission cleaning is carried out on new installments to remove millscale, light surface rust, and cement splashes that may have entered the system during construction. Dirt and debris will also be removed during this process. This procedure involves the use of a suitable solvent followed by high-velocity flushing. The system should be dosed with a suitable corrosion inhibitor immediately after the cleaning procedure is finished to prevent rapid corrosion of cleaned pipework surfaces. Precommission cleaning is carried out in accordance with BSRIA BG29/2020.
Corrosion inhibitors will reduce running costs and extend the working life of the equipment.
This is achieved by:
- Prevention of deposition of scale or other solids onto heat transfer surfaces.
- Protecting the metals from the corrosive effects of water.
- Reduced suspended solids in a system helps avoid system blockages and minimise erosion in susceptible areas such as pump seals and elbows in pipework.
A biocide will also be dosed to control bacteria levels in a system. Some bacteria that may grow in a system may cause health concerns.
Other bacteria may also affect the running efficiency of the system, have a corrosive effect or cause blockages in pipework.
Routine checks will be carried out by our staff to monitor the system and any action required will be taken. Treatment of heating and cooling systems is carried out in accordance with BSRIA BG50/2013.
Dosing equipment can also be supplied and installed to dose these chemicals directly into heating and chilled systems. This dosing will not effect the running of the systems in any way.
Dosing of closed chilled systems with glycol can be carried out to protect the system from pipe and equipment failure caused by sub-zero temperatures.
