Dosing device for the oil and petrochemical industry

Although reagent dosing plants in the petroleum and petrochemical industries do not directly produce products, they are an indispensable “guardian” and “lubricant” in the entire production chain.

Integrated three-chamber device for preparing flocculant

Integrated three-chamber device for preparing flocculant

The three-chamber solution preparation unit is designed specifically for dissolving and preparing solutions of high molecular weight polymer – polyacrylamide (PAM). Mainly used for flocculation treatment of industrial wastewater, flocculation in sludge dewatering, drinking water treatment, and wastewater treatment in chemical, pulp and paper and other industries.

Dosing device for source water

Dosing device for source water

An automated system of equipment for accurately dosing certain chemical reagents into the water being treated (“source water”). The main task is “accurate, continuous, automatic” dosing of reagents, replacing the unstable and ineffective manual method.

Dosing device for circulating water

Dosing device for circulating water

Equipment for automatic and precise dosing of chemical reagents into circulating cooling water systems, boiler plants or other water systems. Its main purpose is to prevent scale formation, corrosion and biological fouling (algae, bacteria) in the system by dosing certain chemicals, thereby ensuring its safe, stable and efficient operation.

Phosphate dosing device

Phosphate dosing device

Hardness ions (calcium, magnesium) in the boiler feed water enter into a chemical reaction at high temperatures or crystallize when the saturation concentration is reached, forming an insoluble scale that adheres tightly to the heated surfaces of the boiler.

Hydrazine dosing plant

Hydrazine dosing plant

Equipment for water-chemical treatment, which is critical in the steam-water cycle of thermal power plants, industrial boilers, etc. Adding microdoses of hydrazine solution to the boiler feedwater reacts chemically with the dissolved oxygen (O₂) in the feedwater to form nitrogen and water.

Dosing unit for injection of ammonia into feed water

Dosing unit for injection of ammonia into feed water

Equipment for water-chemical treatment, which is critical in the steam-water cycle of thermal power plants, industrial boilers, etc. Adding microdoses of ammonia water (NH₂OH) or liquid ammonia (NH₃) to the boiler feed water to increase the pH of the feed water (usually maintained in the range of 8.8–9.3 or depending on specific conditions) allows the formation of a stable protective film of magnetite (Fe₃O₄) on the surface of the metal (for example, carbon steel).

Simple dosing block-modular unit

Simple dosing block-modular unit

The simple modular dosing unit is a complete plug-and-play dosing device. It is designed, manufactured, assembled and tested at the manufacturing plant in accordance with the customer's technological requirements, and then completely delivered to the site.

Dosing device for waste and sewage water treatment

Dosing device for waste and sewage water treatment

The dosing device, specifically designed for wastewater and sewage treatment, is a critical component of the “accurate dosing and mixing of reagents” in the entire water treatment system. It automatically dispenses specific chemicals into wastewater to achieve physical, chemical or biological treatment goals.
