Twin inhibitor and biocide dosing equipment
The inhibitor and biocide dosing pumps are set to the required dosage ratio – normally biocide dosage is 20% of inhibitor dosage.
The digital control timer is set up to run the dosing pumps for the desired duration on a daily or weekly basis. This can readily be adjusted to suit system parameters and routine monitoring of inhibitor levels.
Glycol blending unit
Fully automatic blending unit for make-up supply to glycol treated water systems. Fitted into the make-up water supply to one or more pressurisation units the G520 unit will maintain the pre-set blend ratio in all make-water or top up water supplied. The unit is powered by the water flow and produces the blended glycol solution on demand over a flow range of 10ltr/hr to 2,000 ltr/hr.
Glycol is drawn direct from the supply container or chemical storage tank. Blended water solution is supplied at the same pressure as the incoming water supply.
Stainless steel chemical dosing pots
Dosing pots are required in order to feed liquid chemicals such as corrosion inhibitors into closed systems.
The dosing pots consist of a stainless steel vessel with inlet (return) and outlet (flow) valves, a drain valve and a filling valve. A stainless steel tundish, air release valve, wall mounting brackets and a non-return valve.
Dosing Pots are supplied complete with all valves
Closed re-circulating water systems (chilled or hot water can be simply dosed on a regular / manual basis by use of these dosing pots. Fitted across flow and return lines, they provide a means to annex a portion of the system water which can be drained away and replaced with the chemical to be dosed. When reconnected to the system, the chemical is flushed through.
The dosing pots are fitted with large 1” valves, which ensure quick and easy action of the pot even in low flow/pressure conditions. An air vent valve enables the pot to be purged during filling thus eliminating undesirable air ingress to the system. A NRV check valve is fitted into the fill line below the tundish.
