Closed Systems

Closed systems are typically low pressure hot water (LPHW or LTHW) and chilled or condenser water systems

The problems associated with closed systems are Scale, Corrosion and Microbiological fouling. Phase Technology has specialist knowledge in these areas and can provide complete treatment regimes so that closed systems can operate trouble free.

Treatment and Analysis

The treatment of closed heating and cooling systems is often a combination of chemical and physical means. 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
  • We can undertake on site analysis for instant results or more in depth System Audits provided by our laboratory.


 

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.

Pseudomonas Removal

Analysis and eradication o pseudomonas in closed systems is an area where Phase Technology has proven success using our biocide Phasechem 589+

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.
