Energy-Efficient Exhaust Air Filtration 节能型废气过滤设备
Awareness of environmental protection and clean air
quality is increasing, along with strict regulations for diecast- ing facilities. Tis is increasing demand for KMA exhaust air filtration systems worldwide. KMA Umwelttechnik, Koenigswinter, Germany, special-
izes in energy-efficient exhaust air purification systems for diecasting machines. Te KMA exhaust air filters use little energy to ensure an effective separation of emissions such as greasy, oily and paste-like smoke, dust and fine mist. Aerosols can clog some filter types quickly, rendering them
ineffective and leading to replacement and disposal costs. Chang- ing electrostatic filter cells is not necessary, and they reportedly never obstruct the air flow through the exhaust system. Due to the high filtration efficiency of electrostatic filter
units, the purified air is led back into the production hall. By capturing and filtering the fumes directly at the source, no exhaust air blowers or ducts are needed. In winter, cold fresh air from outdoors must be heated to room
temperature before it is led inside. Tis heating incurs operation costs and adds pollution concerns due to carbon dioxide emis- sions generated in the heating process. Recirculation ensures no heat is lost due to exhaust air replacement from outdoors. Recirculating air saves facilities up to 80% of their annual
operation costs compared to conventional exhaust ventilation systems, achieving a short-term return on the one-time invest-
ment. Tis is accompanied by a significant reduction of CO2 emissions. KMA filter systems help foundries achieve ISO 9,000 and ISO 14,000 certifications. In addition, by not allowing exhaust air to disperse into the
production hall without being purified first, casting machines, peripheral devices, the building itself and its employees will not suffer from the effects of dirty air.
环保意识和对清洁的空气质量要求的不断增加，以及 压铸厂的严格规定。增加了KMA公司废气过滤系统的全 球需求。
KMA Umwelttechnik公司位于德国Koenigswinter 市，专注于节能高效的压铸机废气净化系统。 KMA废 气过滤器能耗低，能确保如油腻，油性和浆糊状烟雾， 粉尘和粉尘雾的有效分离。
空气中的浮粒能迅速堵塞某类型的过滤器，使它们 失效，导致更换和处理成本。更换静电过滤单元是没有 必要的，据报道，他们从来不阻碍废气排出系统的气流 通过
由于静电过滤单元的过滤效率高，净化后的空气被引 回到生产车间。在源头直接过滤烟雾，没有废气排出， 不需要鼓风机或管道。
在冬季，新鲜的冷空气从室外引入室内前，必须加热 至室温。加热产生了操作成本，并由于在加热过程中产 生的二氧化碳的排放，增加了污染问题。再循环用净化 过的废气取代从室外换气，确保没有热量损失。 空气循环设备与传统的排气通风系统比较，每年的运 营成本节省高达80％，实现了一次性投资的短期回报。 同时伴随着二氧化碳排放量显着减少。 KMA公司过滤 系统帮助铸造工厂取得ISO9000和ISO14000认证。 此外，通过不使未初次净化的废气排入生产车间，让 压铸机，周边设备，车间本身及操作者不会受到污浊空 气的影响。
Users can reduce their system’s energy consump- tion by up to 80% in recirculating air mode.
空气在再循环模式，用 户最多可以减少80％ 系统的能量消耗。
