Block fan cooling tower -42 MAXI


/-300 BASIS1 -- name of the cooling tower up to 2011/


Block fan cooling towers -42 MAXI are produced protected with patent and trade mark.

Efficient cooling of circulating water is guaranteed even under the most unfavorable external conditions due to the usage of the latest developments of world level in cooling towers of BROTEP production.

The frame of block cooling towerThe frame of block cooling tower is made of metal framework, mounted at the installation site.

The roof of this cooling tower consists of four segments, which are made of fiberglass reinforced polyester and installed at an angle, thus forming the confuser.

The confuser at the top part of the cooling tower furthers the improvement of air flow aerodynamics, prevents the formation of air blanketing and thereby increases the cooling capacity of the cooling tower as a whole. The use of fiberglass reinforced polyester in the roof structure guarantees high corrosion resistance.

Fan installation with diffuser, impeller and the electromotor is mounted directly on the supporting frame, made of galvanized steel. 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 cooling towers are installed on a pre-prepared pool or attached to already existing one. The time of installation of the cooling tower -42 on the prepared pool is 3 ÷ 5 days. The covering of the cooling tower is made of profile galvanized sheets with a polymeric covering or PVC of sheets.

Polymer irrigator provides high water cooling effect at low aerodynamic resistance, cannot be contaminated, is resistant to low air temperatures.

The tower in ready-to-operate unassembled (separate mounting units) form by road transport.
