| Techquest 421M - is a blend of organic & inorganic inhibitors and dispersants. It is designed for application in chilled water, LPHW & MPHW systems. Protection is afforded to both ferrous & 'yellow' metals. The product exhibits no detrimental effects towards boilers fabricated with aluminium heat exchange modules. | Techquest 424 - is designed for use as a corrosion inhibitor in closed hot water & chilled water recirculating loops. The product contains neither nitrite nor phosphate. | Techquest 427 - is a selected blend of inorganic and organic corrosion inhibitors combined with dispersants for application in Chilled water, LPHW & MPHW systems. Protection is afforded to both ferrous and 'yellow' metals. Note this inhibitor is not suitable for boilers with aluminium heat exchangers (see Tq 421M or 438). | Techquest 429 - is a blended corrosion inhibitor for use in LPHW & MPHW systems. It is based on a blend of sodium nitrite & sodium molybdate. Together with an azole compound this synergistic blended formulation offers good corrosion protection to the ferrous, copper and yellow metal alloys found in heating systems. |
| Techquest 432 - is a well established corrosion inhibitor that combines the ferrous metal passivating properties of sodium nitrite with the anodic inhibiting benefits of silicate. The product also offers protection to copper & copper alloys. | Techquest 434 - is a synergistic blend of corrosion inhibitors designed for the specific protection of both ferrous & 'yellow' metals. It is ideally suited for use in softened water and finds wide application in closed recirculating chilled water loops. | Techquest 436 - is a synergistic blend of corrosion inhibitors designed for the specific protection of ferrous and yellow metal alloys. It is ideally suited for use in softened and chilled water circuits. | Techquest 438 - is a 'total organic' formulation of corrosion inhibitors for industrial closed circuit LPHW & MPHW systems. It can also be used in systems containing aluminium. |
| Techquest 442 - is a NON TOXIC formulation of inorganic inhibitors for use as a scale & corrosion inhibitor in domestic hot & cold water circuits. | Techquest 472 - is a cleaning agent based upon a blend of organic chelants, dispersant & surface active agents. The formulation is designed to remove inorganic deposits from all types of heat transfer equipment. Techquest 472 works in neutral solution and will remove both iron and copper oxides & salts. | Techquest 482 - is for use in closed hot & chilled recirculating water systems. It is based on a blend of organic and inorganic additives for the inhibition of scale, corrosion & deposit control. Techquest 482 utilises a selection of tannins to inhibit corrosion. Overall the product is suitable for use in a wide spectrum of water qualities. | - |
