Product information

DEMKOR

DEMKOR 41 is a highly effective corrosion inhibitor, hardness stabiliser and oxygen scavenger for all steam systems with an operating pressure of max. 68 bar.

DEMKOR 41 has proven itself over decades of use at renowned companies and is also described in professional publications as an efficient and sustainable solution.

The DEMKOR 41 and DEMKOR 81 product lines are used according to the respective operating issues and conditions for oxygen scavenging, corrosion inhibition, and hardness stabilization in steam boilers, warm and hot water systems, and district heating systems. The use of these products opens up great savings potential in terms of water, energy and chemical consumption.

The basis is a specially selected and environmentally friendly tannin-lignin compound that is neither steam-volatile nor salt content-increasing.

The inside of the steam boiler and the pipe system are coated with an iron-tannate layer, which serves as extremely effective corrosion protection and has a neutral effect on heat transfer. At the same time, the stabilisation of the residual hardness prevents the dreaded formation of limescale.

The DEMKOR product range is physiologically and toxicologically harmless in its composition and is listed as a substitute for hydrazine in the current Technical Rules for Hazardous Substances 608 (TRGS 608). The waste water may be disposed of into the sewage system if the required pH thresholds are not exceeded. DEMKOR 41 is currently rated as Water Hazard Class 1 (low hazard).

DEMKOR products are VdTÜV-approved (VdTÜV approval KG 05/41).

Guaranteed savings potential

thanks to DEMKOR

The use of DEMKOR in steam boiler systems offers significant savings potential.

When boilers are converted from conventional phosphate/sulphite to the sustainable and low-salt DEMKOR, the boiler can be operated with higher thickening and lower blowdown requirements. This leads to significantly lower desalting and energy losses. Advantages you can count on:

5 to 10 % savings on water and energy over conventional phosphate- and sulfite-based boiler water conditioning products

10/100

Up to 20 % feed water reduction

20/100

50 to 80 % less blowdown

80/100

Up to 5 % reduction in greenhouse gases during production process

5/100

DEMKOR guarantee

  • Ecological and sustainable boiler conditioning with excellent biodegradable ingredients
  • Prevention of deposits with stabilization of residual hardness that cleans the boiler as it operates
  • DEMKOR tannins guarantee additional corrosion protection through the formation of iron-tannate layers that do not inhibit heat transfer
  • DEMKOR offers extended corrosion protection through rapid absorption of residual oxygen

Case study on DEMKOR

The use of DEMKOR as a boiler water conditioning agent pays off twice over – economically and ecologically. Current results from research and development and from daily use in practice clearly prove this.
