Closed Systems
Closed systems are typically heating (LPHW or LTHW), chilled or condenser water systems
Water quality problems associated with closed systems are Scale, Corrosion and Microbiological fouling. Phase Technology has specialist knowledge in these areas and can design a complete treatment regime’s so that closed systems can operate trouble free.
Phase have significant experience in the sampling, monitoring and treatment of closed water systems working inline with BSRIA BG29 Pre commission cleaning, BgG50 Water Treatment, BSI BS8552 Closed Systems sampling.
Treatment and Analysis
The treatment of closed heating and cooling systems is often a combination of chemical and physical applications. Phase Technology has a range of chemical products suitable for different system components. Our chemical inhibitors, combined if necessary with filtration provide excellent protection to closed systems.
Analysis
Our technicians undertake onsite chemistry analysis for on the day results and reporting. For more technical System analysis we submit samples to our laboratory for testing and then provide sample certification with recommendations as required.
Remedial Works
Whether through inappropriate treatment or incorrect pre-commission cleaning Phase Technology can provide a solution to the problem
Chemical Cleaning and Flushing
The type of cleaning depends on the severity of the problem and other constraints such as an occupied building or the need to keep a system operational. Often chemical cleaning agents and flushing is used in conjunction with temporary filtration to achieve the bet results.
Pseudomonads Removal
Analysis and eradication of pseudomonads in closed systems is an area where Phase Technology has proven success using our biocide range.
Filtration
We are able to offer a range of cyclone and media filters to control and remove suspended solids from closed systems.
Descaling
Scale can cause significant problems for equipment such as condensers, plate heat exchangers and calorifiers. Phase Technology can provide a descaling service to restore plant to a safe condition and maximise operational efficiency.
