DK CHEMO - Cleaning-In-Process Specialist
Heating as well as cooling causes gradual depositing in water and heating systems of mineral and organic substances always contained in input water. In systems operating over long periods of time, there is always the formation of solid depositions (incrusts formed mainly from calcium and magnesium carbonates, sulphates and iron compounds) and deposits on heat transfer surfaces in spite of the dosage of corrosion inhibitors and substances against the formation of deposits. The discharged substances can additionally cause the obstruction of the systems (heating system distribution lines, fittings, exchangers, etc.).In places with reduced circulation (e.g. radiators, hot water tanks) there are additionally deposits in the form of dregs which comprise organic sediments and released particles of solid incrusts.These are formed not only on metal pipelines and fittings but also on the surfaces of plastic pipelines and fittings. The assets of chemical cleaning can be summarized as follows: A quick and a truly effective way to remove the unwanted effects caused by sediments (increase heat loss, increase consumption of circulation and circulating pumps, insufficient heating of buildings, insufficient pressure in the distribution system, etc.) The chemical bath operates in the application instantly and immediately after chemical cleaning positive results can be recorded. Immediate savings in energy (heat, gas, electricity). Annually the savings can amount to 15-30 % of the total costs for heat depending on the system and equipment. It extends the life of purified systems and their elements through preventing corrosion. It maximizes the efficiency of heat transfer and increases thermal comfort. No need for complex logistics, as it can be performed with on-site cleaning equipment. The amount expended on chemical treatment is significantly lower than the reconstruction of the systems, which also require significant intervention in the operation of buildings. A return on the investment in Cleaning-In-Process takes place in the range of 1-3 years, depending on the system and equipment.
continueAs to the renovation of systems by means of chemical cleaning, the servicing activities of DK CHEMO Ltd at present particularly focus on the following systems and facilities: Heating systems (vertical as well as horizontal mains + central heating bodies). Hot water distribution systems. Plate heat exchangers / with a special focus SWEP and Alfa Laval products. Tube-type exchangers / with a special focus on SECESPOL products. Cooling systems / with focus on TRANE, York, Carrier products. Industrial gas boilers / with focus on Viessmann, Viadrus, Buderus products. Boilers and water tanks for hot water and drinking water (including the application of anti-rust paint). Stationary compressors / with focus on Atlas Copco, Kaeser products. Point or pitting are the most common causes of deterioration of metal materials, so anti-rusting paint on the walls of tanks and storage water heaters after chemical cleaning, which penetrates to places affected by corrosion and stops its further progression is also offered to customers.The organically-based porous coating of the paint prevents the aggressive actions of salt and with its minimum life of 5-7 years, the customer can continue to use existing facilities rather than to immediately invest in the acquisition of several new and more expensive ones. The paint is tested for contact with drinking water and meets the safety regulations applicable by the Ministry of Health. No. 409/2005 Coll. and No. 252/2004 Coll.
continueIn the chemical cleaning field the company DK CHEMO Ltd. is a pioneer in applying modern technology which transparently illustrates the results of cleanup. We have industrial design monitoring systems for use in extreme conditions and we can show the status of the equipment and complete systems to the customer before the chemical cleaning, during it, and in the final stage of the purification.We can also provide a thermal imaging and visualization camera as a side business service and the customer can use this option only in preventive control that can detect hidden defects especially in hard-to-reach places and so fundamentally assist in determining the subsequent corrective actions. To maintain efficiency in terms of the life of heat and hot water equipment, it is necessary to monitor the characteristics of energy waters, which are the main cause of the creation of sediments, therefore a part of our monitoring services is also the chemical analysis of water, whose parameters according to ČSN 07 7401 we include in the output report of the contract.

continueThe Czech company originated in 1984 while an originally associated entity developed into an independent company. It has become familiar with the heating and gas industry over the years as regards the chemical cleaning of energy facilities focusing on water and heating systems.In 2009, the final changes took place in the organization and the current name was changed to DK CHEMO Ltd. The company applies an integrated management approach to ISO 9001:2008 (quality management system) and ISO 14001:2004 (environmental management system), which have officially certified company procedures and skills for which it is requested by its customers in the Czech Republic and abroad: 30 years of experience in the field. The optimum combination of active agents in the cleaning compositions ensuring the complete removal of silt is part of the longstanding "know-how" of the company. Chemical products are fully respectful towards the construction materials of the purified systems and towards the environment. Using the CIP method (cleaning-in-place). With the help of mobile devices time delays with downtime are minimized and it can also often work well with full operation of the system without having to disconnect (heating system). Adequate technical facilities for cleaning systems on a smaller scale (small reservoirs of warm water, water heaters, etc.) as well as for extensive activities (heating systems and cooling systems). Continuous investment in new technological resources in order to optimize the cleaning process and diagnostic systems. Own car fleet. Processing expertise for a specific contract. It includes specifications of the problematic, including a description of methods and procedures used in the evaluation of the project in terms of reliability, durability and in particular, energy savings. Energy audits are elaborated in accordance with the wording of Act 406/2000 Coll. (§ 9) and regulation 213/2001 Coll. Cooperation with leading Czech research institutes and higher education institutions in the field of water analysis, chemical and structural materials analysis.
