BIOCIDE
DHS 3700 is a stabilised biocide for low temperature heating and renewable energy systems to prevent the growth of bacteria and fungi. DHS 3700 eliminates problems caused by micro-organisms such as blockages of the pipe work, manifolds, valves and heat exchangers, and it is very effective in sanitising the ground loop in GSHP systems.
FLUSHING FLUID
GHS 5800 is a mildly alkaline solution containing special dispersants and designed for use as a cleaner in ground source heat pump loops. Glycol-based thermal fluids can degrade over time because of the stresses of cycling temperatures, and they are often accompanied by bacterial attack. GHS 5800 will effectively remove any sludge, deposits or blockages caused by degraded thermal fluid.
