Cleaning and protection


DESCALING PUMPS:


DOS 25 V4V
serves for removing scale from sanitary water heat exchangers, heating circuits, storage water heaters, boilers etc. The pump is equipped with a 4-way valve enabling reverse flow of the descaling liquid and thus better results in cleaning.

TARTARUGA V4V
is a lighter and easily portable pump for less demanding applications. It is also equipped with a 4-way valve enabling reverse flow of the descaling liquid.

CHEMICALS FOR DISCALING PUMPS

CLEANING AGENTS: Code
DETEX - intended for cleaning copper and steel parts. Solution: 1 kg Detex for 6-10 l of water. 649
MANTEX SP - for cleaning components in stainless-steel, copper and tin. Dissolve 1 kg Mantex in 6 l water. 650
MANTEX SNO - for cleaning aluminum or light alloy parts. 2134
NEUTRALIZATION AGENTS: Code
N105 - liquid for neutralization of residual acidity after cleaning. 4006
pH METR - a digital tester helps in checking the acidity of descaling solutions, range 0-14 pH, accuracy ±0.2 pH, suitable for all current measurements of acid solutions. The measured value is shown within seconds, the battery will last for some 700 hours of continuous measurement. 652

FIRE-SIDE BOILER CLEANING PRODUCTS

GAS-FIRED BOILERS: Code
METANOTHERM - liquid combustion deposit remover. Its chemical reaction will clean heat transfer surfaces that cannot be reached by manual cleaning methods. It is especially suitable for cleaning gas-to-water heat exchangers in wall-hung boilers. Supplied as a spray or in 10-l plastic cans. spray: 1977
10-l plastic can: 424
OIL-FIRED BOILERS: Code
EC-MIX - non-toxic powder combustion deposit remover for oil-fired boilers. It is introduced into the combustion chamberand after the boiler is fired, the combustion chamber and all the heat transfer surfaces will be cleaned. 1368

LIQUIDS FOR CLEANING AND PROTECTION

HEATING SYSTEMS: Code
MR 501/R - concentrated alkalic scale dissolving corrosion inhibitor for heating systems. The dislodged scale and other impurities are purged by flushing the system 2 to 3 weeks after its application. Concentration: 2 kg M501/R for 80-100 l water. 433
MR 501/F and MR 501/96P - give preventive corrosion protection by forming a protective film on the surface. They are mixable with anti-freeze liquids (e.g. for solar systems). Older heating systems should be cleansed prior to the application by using MR 501/R liquid first.
MR 501/F - gives preventive corrosion protection to metal materials (iron, copper, aluminum etc.) and their alloys. 1 kg M501/F shall be diluted in 100 l water.
MR 501/96P - is intended esp. for heating systems containing plastic components (e.g. underfloor heating). It prevents algae growth and gas formation. 1 kg M501/96P shall be diluted in 100 l water.
M 501/F:   434
MR - 501/96P 4402
CORROSION PREVENTION: Code
ZINCOL spray for cold zinc spraying. An excellent surface finish and corrosion protection. Thanks to high
zinc content (95%) the coating never peels off, and the surface can be sprayed without any special pretreatment
