Self-supporting drift eliminator and fill structures have no domestic equivalents and do not require additional supporting frameworks during installation or modernization of cooling towers.
The blocks are manufactured in full compliance with construction standards and are designed for efficient installation. Two technicians can assemble a 144 m² section within one working day.
The design is suitable for all types of mechanical draft cooling towers with section areas from 2 m² to 192 m², as well as natural draft towers with areas up to 10,000 m².

The fill is made of polypropylene (PP) or low-density polyethylene (LDPE) and is used in both mechanical draft and natural draft cooling towers.
The elements are arranged at a 60° angle. The trapezoidal corrugation has a rib height of approximately 20 mm and a pitch of about 46 mm.
The mesh filament diameter is 1–2 mm, providing a high contact surface between water and air (over 125 m²/m³). Combined with low aerodynamic resistance, this ensures high cooling efficiency.
The fill is designed for circulating water cooling.

The company supplies components for cooling towers, including nozzles and spray systems.
Water nozzles are designed for liquid distribution in cooling equipment, including cooling towers. The efficiency of cooling largely depends on the uniformity of water distribution over the fill and the degree of atomization. The nozzle design ensures the formation of a spray pattern that provides uniform irrigation density.
A well-developed spray pattern ensures high distribution efficiency (flow coefficient – 0.96, hydraulic head – less than 3 m of water column). Uniform water distribution across the nozzle cross-section and effective atomization provide stable cooling performance, while the конструкция ensures high mechanical strength.
The presence of a swirl insert in the central orifice prevents direct water jet impact on the drift eliminator during startup conditions, improving operational reliability.
In addition, VODEH equipment offers a competitive cost level combined with guaranteed quality and durability.

2.00 | 11.0 | 1.70 | 1.70 |
The operating temperature range is from −60°C to +80°C. The nozzle operates at a pressure range from 0.5 to 50.0 m H₂O, with water flow rates varying from 3.5 to 9.4 m³/h. At a pressure of 2.4 m H₂O, the flow rate reaches 9.4 m³/h and remains stable with further pressure increase.
The nozzle can operate in contaminated circulating water systems with solid particles up to 20 mm in size.
The impact nozzle “VODEH” is manufactured in accordance with TU 3672-08-64564585-2013.

Installation of hydrolocks is carried out during positioning of formwork panels. Metal tie rods are installed between the panels at a specified spacing, with length corresponding to the wall thickness of the structure. At the initial stage, the rods pass through the hydrolock and then through the connecting tube.
After concrete placement and curing, the formwork panels are removed and installed at the next level. Hydrolocks remain embedded in the concrete, and the openings are sealed with special plugs.
The company is ready to supply any quantity of products with delivery across Russia.
