CLOSED SYSTEM TREATMENTS
Chemiteq supply a range of cleaners and inhibitors for closed systems, some of which are NSF approved (formerly BuildCert).
It is recommended that a suitable treatment programme is in place according to the Approved Code of Practice and Guidance (ACoP L8), HSG 274 and the latest BSRIA Guide.
We can also offer products which meet VDI 2035 standards. VDI theory is based on low conductivity, low dissolved oxygen and controlled pH.
All our products are tried and tested formulations. We offer a range of concentrated products which means lower dose rates, less plastic waste and a potential saving on transport. We also offer non-chemical options.
SYSTEM CLEANERS
Our system cleaners have a recommended dose rate. This is proven to work in the majority of cases. However if the system is particularly dirty, more product may be required or multiple cleans may be needed. Please see separate data sheets for further information. CQ6015 is a low dose rate product.
CQ6015 – Low dose rate
Iron & scale removal and pre-commissioning cleaning.
Recommended dose rate = 0.25% (2.5L/m3)
pH as supplied = 7
CQ6012
Good for iron and scale removal and pre-commission cleaning.
Recommended dose rate = 1% (10L/m3)
pH as supplied = 4-5; neutral in reaction
CQ6020
Polymer cleaner. Good for renovation of older systems. Can be used as an online cleaner. Compatible with most water treatment products.
Recommended dose rate = 1% (10L/m3)
pH as supplied = 7
SYSTEM INHIBITORS
Our inhibitors are designed to work in multimetal systems. CQ4516 and CQ4517 are for use in systems containing aluminium, whereas CQ4518 is for multimetal systems without aluminium. All our inhibitors have low dose rates.
CQ4516 – Low dose molybdate
Suitable for multi-metal systems including aluminium.
NSF certified.
Recommended dose rate: 0.25% (2.5L/m3)
pH as supplied: 7
Measurement: 100-120ppm as MoO4
CQ4518 – Low dose nitrite
Suitable for multi-metal systems without aluminium
Recommended dose rate: 0.33% (3.3L/m3)
pH as supplied: 12-13
Measurement: 800-1200ppm as NaNO2
CQ4110 – Low dose synergised nitrite
Suitable for multi-metal systems without aluminium
Recommended dose rate: 0.2% (2L/m3)
pH as supplied: 12-13
Measurement 200ppm as NaNO2
CQ4517 – Low dose molybdate/ nitrite blend
Suitable for multi-metal systems including aluminium
Recommended dose rate: 0.43% (4.3L/m3)
pH as supplied: 7
Measurement: 300ppm as MoO4 and 300ppm as NaNO2
It is highly recommended to test on both MoO4 and NaNO2
to ensure the system is functioning correctly.
