Non Toxic Extreme Temperature Rated Heat Transfer Fluid with Antifreeze Function. Based on Propylene Glycol and Reversibly Evaporable Inhibitors to prevent corrosion, scaling and biological fouling.
Solaris PGC has been especially formulated for use Solar Thermal Heating Systems. It is able to operate efficiently at 170°C for prolonged periods and withstand temperatures of 200°C for short periods. It contains reversibly evaporable inhibitors that are capable of withstanding stagnation temperatures of 300°C whilst protecting all metals used in Solar Thermal Heating Systems.
Solaris PGC is miscible with water in all proportions and can protect Solar Thermal Heating Systems down to -50°C depending on concentration. Solaris PGC exhibits super-cooling characteristics and mixtures containing in excess of 50% by volume do not freeze solid, alleviating any concern over possible expansion and burst damage.
Solaris PGC has an LD50 toxicity rating (Oral Rat) of ≥15,000 mg/kg of body weight (bw) = “Relatively Harmless”. As confirmed by the Hodge & Sterner Scale.
Solaris PGC with reversibly Evaporable Inhibitors has been tested in accordance with BS5117 procedures and found to meet BS6580 and ASTM D1384 corrosion limits.
Solaris PGC also contains a high temperature rated polyacrylate, formulated to prevent sludge precipitation and scale formation. Thus promoting long operational life and high thermal efficiency.
Solaris PGC mixtures are readily biodegradable (90% over ten days) and will not remain in the environment or bio-accumulate.
All Hydratech products are manufactured in accordance with certified ISO9001-2008 procedures
As per BSRIA guide BG 29/2012 all pipe-work systems should be clean and free from biological contamination and debris prior to commissioning.
To minimise corrosion air ingress should be minimized. A pressurised system is best.
Solaris PGC is a concentrate Heat Transfer Fluid that can be diluted with a demineralised or UltraPure™ water, to achieve various freeze protection temperatures. In order to maintain system integrity only top-up with Solaris PGC.
