This is a question we are frequently asked when dosing chemicals in parts per million (ppm). In an attempt to help our readers we have provided the following.  Calculation assumes SG is 1:1 100ppm = 100mg/L = 0.1L/m3 500ppm = 500mg/L = 0.5L/m3 1000ppm = 1000mg/L = 1L/m3  

Which one to choose? With winter upon us, we thought we would try to shed some light on the options available for antifreeze agents.  When we think of antifreeze agents for closed systems we generally associate these with Mono Ethylene Glycol (MEG) or Mono Propylene Glycol (MPG).  MEG for use in non food contact and MPG for use in incidental […]

Using two REACH and BPR compliant chemistries we are now pleased to be able to offer a fully automated alternating non-oxidising biocide regime for solid chemicals! Formulated solid products have been in use for a number of years with great success in cooling towers and evaporative condensers. However, solid biocides have so far been limited to oxidising biocide technologies either used […]

It is important to complete a thorough survey of a closed system. You will need to know the volume (or at least a good approximation), the metallurgy, any known problems eg: leaks, corrosion, scale etc. Usually a closed system will be one of the following – LTHW (low temperature hot water), HTHW (high temperature hot water) or some sort of […]
