Wind chassis htfc cabinet centrifugal wind chassis dfx series of low-noise wind chassis Lu Sheng HVAC

1. The series are constructed of DGT -1 type axial air box and DGT -2 type centrifugal wind chassis in two versions: DGT-1 type axial air enclosures for civil fire smoke or exhaust ventilation , is a low-noise high-efficiency fan with compact structure, good performance, easy installation, etc. can be used for high-rise buildings, underground civil air defense projects, underground garage, culverts and other mines of smoke and exhaust, especially in high-rise buildings on the roof platform use, its more prominent features of the product reduces equipment noise, in line with environmental requirements. DGT-2 centrifugal wind chassis host using air-conditioning fan, before the choice of the multi-blade impeller with flow, high pressure, low noise, light weight and other characteristics. 2. DGT series of low-noise wind chassis according to the different requirements of senior civil ventilation, the use of multi-speed three-phase asynchronous electric drive, with speed adjustable fans and air pressure can be varied over a wide range, suitable for a wide range of features , one machine can reduce the engine room area, save investment and operating costs. Gas transport wind chassis 3. This should air or other combustion of non-corrosive steel material gas. It must not contain in the gas viscous material, and the content of dust and hard particles should not be a big 150mg / m3. 4. DGT series Wind chassis has A and B are two types for users to choose the motor with a cooling system for the A-type device, the motor does not have a cooling system for the B-type devices. A wind-chassis exhaust fan fire to do with the wind chassis more than 40 minutes of continuous operation at 280 ℃ under the temperature conditions at 150 ℃ temperature conditions can be run for a long time. Exhaust wind chassis specifically designed for the high-temperature exhaust fan equipped with hot motor, totally enclosed motor built, and a special motor cooling system to ensure safe use of the electric motors at high temperatures. After optimization design goal, the company produces high-temperature exhaust fan, high temperature performance, high efficiency, low noise, reasonable structure, small size, easy installation, etc., installed on horizontal, vertical, lifting can be. After the exhaust wind chassis efficiency is close curved airfoil centrifugal fan. Changing conditions, especially at low load area, whether it is adjustable vanes or rotor blades adjustable hood fan, than using an axial inlet centrifugal fan adjustable deflector economy is high. Centrifugal fan and exhaust duct chassis with different adjustment method, more power consumption. Blade-adjustable hood fan is in operation the lowest power consumption, especially in the low-load power consumption of less merit more prominent. Centrifugal fan inlet deflector adjustable maximum power consumption. Even the entrance deflector adjustable hood fan power consumption is also significantly lower than the centrifugal fan. But centrifugal fan inlet deflector adjustment, re-use two-speed motor drive, at the low load operation, also significantly reduces power consumption.
