Helamin HS 190 H


HELAMIN HS 190-H is a scale and corrosion inhibitor for complete protection of
both closed recirculation hot water plants and chilled water systems. Water
treated by HELAMIN HS 190-H should not be used as drinking or washing
water. HELAMIN HS 190-H forms an adsorbed molecular film onto surfaces,
protecting them against the corrosive attacks by water and dissolved gases and
preventing the adhesion of any deposits.
HELAMIN HS 190-H is able to control pH of generator water and heated or
super-heated water lines. In addition, HELAMIN HS 190-H also assures the
complete protection of chilled water systems.
Physical properties:
- Composition: mixture of polyamines & polycarboxylates in aqueous
- Appearance: a slightly yellow solution fully soluble in water.
- Specific gravity/ density: 1.05 ± 0.05 at 20° C
- pH-value: 11.5 ± 1.0 at 20° C
- Thermal stability: 550° C
- Freezing point: -3° C
- Freeze-thaw stability: excellent
Single product, in ready-to-use liquid form, simply dosed to the system:
· prevent corrosion on iron, steel and copper (and its alloys)
· improves heat exchange by keeping heat transfer surfaces free from
deposits of any origin
· does not increase salinity of water
· simplifies control tests requirements
Meets and exceeds Recommendations R54/CEOC/CP 84 DEF requirements for
boiler water and boiler feed water (CEOC: Association of European Control
HELAMIN HS 190-H can be introduced at any point of the plant by automatic
dosing pump. The normal dosage is 500 - 1000 g / m3 (per cubic meter of
heating system water volume).
In heating or chilled water system, the residual polyamine excess measured by
HELAMIN Test Kit should be within range of 10 - 30 g / m3.
Please note that in certain cases, the amine loss by adsorption is not directly
proportional to the decrease of the pH value which should be maintained near 9
Important note:
· HELAMIN HS 190-H should not be mixed with common water additives (such
as phosphates, tannins, de-foaming or dispersing agents) which will destroy the
advantageous effects of the inhibitor.
· Before use in new carry-out system, a chemical cleaning is required to remove
natural or corrosion oxides and deposits (greases, sand, cement) prior to
introducing HELAMIN HS 190-H into the system.
HELAMIN HS 190-H is supplied in non-returnable 30, 60, 210, 800 and 1000 Kg
