EmiratesGreen offers complete maintenance services for Solar Water Heating System such as following
Depending on the condition of the existing fluid and solar power system (especially the pipework) there are a few options for flushing and filling these systems, such as
If the current fluid in the system is satisfactory with no deposits or degraded glycol attached to the walls of the pipework, then you can simply drain the existing glycol, flush the system with fresh water, drain the water and re-commission the circuit with new fluid. Options for concentrate (neat)
N.B. Particular attention should be paid to the condition of the pipe work itself even though the glycol looks in good condition
If your client is looking for a pre-commissioning biocidal flush prior to the fresh glycol commissioning to ensure no bacteria nor algae growth in the system, the system will need to be drained of the existing glycol, flushed with fresh water, drained and it is recommended to use biocidal-flush in mixed with water in certain proportion, follow the procedures on the technical data sheet, drain the biocidal flush, flush with water, then finally re-commission the circuit with fresh fluid.
If an existing solar power system has suffered a degradation of the glycol within it, below is recommended using the following product which will remove the degraded glycol from the walls of the pipework (brown deposits) and restore the system to a clean and efficient circuit. Another point to note is that possible the glycol may have degraded within the solar array but not within the rest of the circuit. Again, particular attention should be paid to this as the diameter of these tubes are generally significantly narrower and will have a greater effect on the efficiency of the system. It may be prudent to dose the solar panels with a cleaning agent as a preventative measure and as the volume of this would be lesser therefore the costs would be kept comparatively low.
EmiratesGreen offers and uses the solar heating system cleanser which dissolve severely degraded glycol deposits caused by panel stagnation overheating.
The specialized solar water heating system cleaner has been developed in Laboratories and contains a unique formulation of hybrid solvents, alkalis and dispersants. The cleanser product has been rigorously tested in the field by leading Solar Installers and has proved to be the most powerful and effective solar heating system cleaner available.
