Systems cleaned

GOTAR Technologies customers often need maintenance of systems such as water and glycol cooling systems, lubrication systems, hydraulic systems, and process systems.

Water, air, and glycol cooling systems (heat exchange)

Since it first began its industrial activities, GOTAR Technologies has specialized in cleaning heat exchange systems. Regardless of the contamination found in these systems—limescale, organic matter, oil, or degraded glycol—Gotar procedures and cleaning products provide impeccable results that reduce energy use, improve performance, and save on capital costs. 

Lubrication systems

Lubrication system cleaning is another Gotar specialty. Numerous solutions developed over the years ensure impeccable results to restore equipment to its original performance level. Regardless of the degradation or condition of the oil and grease, Gotar products will turn the situation around. From oil varnish to carbonization, even the most difficult problems have a solution.

Hydraulic systems

The cleaning of hydraulic systems is tricky work. GOTAR Technologies has acquired the necessary know-how to clean the biggest hydraulic systems in the world, and to handle oil filtering in accordance with the required ISO standards. The company’s know-how allows customers to rapidly recover their investment in maintenance operations and almost immediately re-establish the equipment’s original performance.

Process systems

At the customer’s request, Gotar solutions can be used to clean process systems. Personalized solutions can also be developed if the available methods are insufficient. GOTAR Technologies has successfully carried out R&D projects to resolve some of the most stubborn problems, while at the same time yielding an excellent return on customer investment.

Surface treatment

Surface treatment is a wide-ranging speciality that encompasses several different areas, including the cleaning of equipment parts, the decontamination and preparation of surfaces prior to painting, the decontamination of painted surfaces, and the pre-operational preparation of industrial systems. GOTAR offers effective solutions adapted to the challenges of surface treatment and suitable for a wide variety of contamination types. Adapted for different metallurgies and to meet customer requirements, these solutions yield excellent results for the elimination of oxides, scale, organic matter, oil and grease, and other contaminants.
