Ventilatory coolers of the VG series are intended for cooling of reverse water in the closed water reverse cycles with a consumption of water from 3000 to 30000 m3/hour and specially developed for the giant enterprises of the metallurgical, petrochemical industry, and also combined heat and power plant and nuclear power plants.
Coolers of the VG series belong to open counterflow coolers and work by the principle of a countercurrent of water and air streams. Air arrives through entrance windows the coolers located below, passes through a sprinkler towards to a water stream, and at a high speed is released into the atmosphere.
Coolers VG I am, as a rule, blocked in one case with quantity of sections from 2 to 4. (According to standard requirements for the enterprises of this sector of the industry of regarding obligatory reservation the equipment: "Quantity of units of equipment not less than 2 pieces"). As each section of the cooler has the ventilatory installation and is capable to work independently, sectioning by addition of reserve section allows to provide reservation of work of the cooling equipment. Reservation allows to carry out scheduled-preventive repair work without stopping of all processing equipment.
When blocking several sections of coolers specify an index in the name of the cooler corresponding to quantity of the blocked sections. Also specify the area of one section of the cooler in the name of the cooler. For example, 4VG-144 - 4th the section ventilatory cooler the area of section is 144 sq.m (the section 12kh12m size, the general size of the cooler 12kh48m).
