Cooling tower BMG

Production

A block type BMG-210M micro-cooling tower of the new generation consists of the modular metal carcass. It has sheeting, a water-distribution system, a plastic drain pan, and highly effective polymeric sprinklers and drift eliminators. Slow-go, two- speed motor fan with a noise absorbing body and with improved aerodynamics. The ventilating fan is equipped with high-profile polished blades made of the multilayer fiberglass, manufactured per aviation technology. It is a low noise fan. The air is supplied by the ventilating fan in a mode of regulating of turns that allows minimizing electric energy consumption. The electric motor is three-phase, slow-go, sizing is selected as per the calculations of power required, it has a full protection from corrosion and moisture penetration inside the motor, it is cooled by the outdoor air, windings and bearings have protection against high temperature, vibration monitoring is provided as well. A special mode for windings heating and drying is foreseen to preserve insulation in safe condition at lengthy downtime.

Replacement of СК-400 cooling tower for BMG-210М (ОАО Acrylat, City of Dzerzhinsk )

Replacement of СК-400 cooling tower for BMG-210М (ОАО Acrylat, City of Dzerzhinsk ) of 3500 m³/hr capacity, on the site of D = 22m2 (installation was done on the same place on top of the old basin without its capital repairs, cost of revamping 2÷3 million rubles, power consumption goes down from 250 KW to 110 KW).
In this particular case the design solution excluded: expensive concrete basins typical for standard cooling towers, the cooling towers proper, pumping house with in ground machine room and concrete inlet chambers with obsolete pumps.

Автоматическое регулирование температуры воды, электронная система антиобледенения, полный мониторинг.

Examples of BMG-210М cooling towers use in closed-circuit water systems.

City of Revda, Nizhneserginsk ММZ. Water block capacity on the bases of BMG-210М mounted on the roof is W = 57Мegawatts. Floor space F=140m2 Q=2450m3/hr.
