/ÁÂÃ-400 “DUET” Ì1 – name up to 2011/
Block fan cloning towers 2ÁÂÃ-36 “VIRTUOS” are protected with patent and trade mark.
Thermal design of cooling towers, structural design, choice of materials and components are made in accordance with the technical requirements. Only materials of premium class and mechanical equipment, the work reliability of which was time-tested, are used in structure of the cooling tower. The final optimal design solutions represent a combination of modern methods based on computer technologies with long-term operational practices proposed

The frame of block cooling tower is made of metal framework, mounted at the installation site. All interior and exterior metal frameworks of the tower are treated with special high efficient anti-corrosion coating. The covering of the cooling tower consists of profile sheets fiberglass reinforced polyester. The roof of this cooling tower consists of four segments, which are made of polyester reinforced with fiberglass and are installed at an angle, thus forming the confuser.
Polymer irrigator provides high water cooling effect at low aerodynamic resistance, cannot be contaminated, resistant to low air temperatures.
The fan installation, which provides air flow, is situated at the top part of block cooling tower. The fan installation consists of an impeller with plastic blades, diffuser and 9 or 13 kW (depending on the required cooling capacity) electromotor.
To ensure optimal operation mode of the electromotor and the fan installation, depending on the atmospheric parameters and the cooled water temperature, the cooling tower is equipped with a control and monitor system with frequency-regulated drive, which significantly reduces the power consumption. The water distribution system of the cooling tower is made of plastic.
The tower is supplied in ready-to-operate unassembled (separate mounting units) form by road transport. It is installed on a pre-prepared pool or attached to already existing one. The time of installation of the cooling tower on the prepared pool is 4÷7 days.
