Use; 1.MHL3-2A, MPYH-14A (MHTFL-14A) Francis two-speed high-temperature exhaust fan for tunnels, underground garage, metallurgy and other high-temperature exhaust, in the case of fire, smoke can quickly cool down, row Smoke fan prices to help firefighters to enter the disaster area fire, fire safety is an essential facility. 2, the type of gas transportation: air and other non-natural, harmless, non-corrosive gases for just, in special circumstances, the choice of explosion-proof Francis fan. 3, impurity gases inside: adhesive materials are allowed within the gas contained in the dust and hard particles is not greater than 150mg / m3. 4, the temperature of the gas: MHL3-2A, MPYH-14A (MHTFL HTF (A) fire temperature exhaust axial fans using advanced CAD-aided design systems, exhaust fan maintenance, is the more optimized design developed new products with high efficiency characteristics curve flat, conducive to energy conservation. Optional molded axial flow impeller, built high temperature motor, arranged a special motor cooling system use two-speed motor direct-drive, to one machine (that usually send row ventilation and fire when using high-temperature exhaust), arranged after the electrical control box can remote automatic control with a high temperature performance, high efficiency, small size, ease of installation (horizontal, vertical, lifting can be), etc., are widely used high-rise building, drying room, underground garage, subway, tunnels and other occasions to send fire smoke and exhaust ventilation Press GA211-1999 Fire fan high temperature test methods, can run continuously at 400 ℃ high temperature more than 100 minutes, the medium temperature 100 ℃ under conditions of continuous operation 20 hours / time is not damaged, has been approved for use by fire departments in major cities nationwide. Fans of the series may use the occasion of the installation requirements, peripherals silencer box, Chuxiong exhaust fan, made HTF (A) -X box-shaped exhaust fan fire works: usually two-speed high-temperature exhaust fan at low speed in order to meet the exhaust air flow, when a fire occurs, the temperature exhaust fan in the cabinet under the joint control of the role of automatic high-speed operation, in order to meet discharge Tobacco needs, while fire smoke partition exhaust pipe smoke damper and smoke damper makeup air duct smoke and make no operation of wind, automatic smoke damper smoke partition in other linkage control the role of the cabinet automatically turn off when the flue gas temperature reaches 280 ℃, automatic smoke damper will automatically close, exhaust fan and make the fan automatically stop. storey 3.5 m, a total of five smoke partitions, fire protection design using the air conditioning and ventilation systems and smoke exhaust system combined approach. selected two-speed high-temperature exhaust fan, high speed exhaust volume of 63500 m3 / h, low exhaust volume of 35400 m3 / h, sending fresh air and makeup air unit air volume of 32000 m3 / h, all with automatic smoke damper fire damper smoke exhaust fan use |. Chenyu air conditioning (certified) | Chuxiong exhaust fan by Wu Cheng Wu Chen-yu air-conditioning Limited. City Chenyu Air Conditioning Equipment Co., Ltd.
