Cooling towers BMG-2000
The detailed characteristic cooling towers BMG – 2000
- You receive the new and import equipment with service life more than 15 years !!!
- You receive power saving up equipment, power consumption decreases in 1,5÷2 time!!!
- You receive the fan with protection against a moisture IP-65, soft start-up, the control and drying of isolation of the electro-engine that excludes annual dismantle and the fan installation, which resource more than 70000 hours.
- You receive градирню with electronic system of an antiicing in a power saving up mode (a backspacing on 30 % of capacity of the fan)
- You receive cooling tower with thermal capacity twice above than under the thermal project т.е you receive two градирни, and the second is free. For example at modernisation градирни BG-900 building new at the price of 70 million руб from modernisation 2 BG-900 is excluded. On Magnitogorsk Metallurgical industrial complex the economy - 120 million rbl. is received.
