product description
The frame of Dongfulong Dehui combined air-conditioning unit adopts high-strength aluminum alloy frame with closed cavity, and the surface is spray-treated, which is firm, beautiful and corrosion-resistant.
 
We commissioned Tofflon Airex to conduct dozens of experiments on the corrosion resistance of the nine insulating materials we selected, and finally chose ABS plastic as the material for the heat transfer in the partition box, except for the material itself. In addition to the physical properties of the clean room, this material has good compatibility with hydrogen peroxide gas, and the process of disabling in the sterilization cycle is also ideal.
 
The box body adopts the sandwich panel structure, and the ABS plastic frame is used to completely separate the inner and outer panels of the air conditioner box, realizing a true "broken" cold bridge.
The overall fully welded filter frame is a professional manufacturer of purification equipment. It is very clear that 95% of the reasons for the unqualified cleanliness detection come from the filter installation frame. We refrain from using the assembled filter mounting box because we know that creating a leak is only a matter of time. We have designed a filter quick-release buckle for you, and continuous improvement makes it more reasonable. A small part, we have now optimized several versions. The primary filter is a G-class (EN779) bag filter, the frame is made of aluminum alloy frame, no seam seal is sealed, the filter material is ultra-fine synthetic fiber hot-melt forming, the dust holding capacity is large, and the filtration efficiency is 95%. Above (weighting method efficiency. It is equipped with a disc type differential pressure gauge with a stainless steel frame. The spring type compaction device facilitates filter replacement.
The wind speed of the wind cooler on the windward surface is ≤2.2m/s, which greatly reduces the energy consumption of the operation; (10,000 air-conditioning units, saving 6650 degrees of electricity per year) patented cooler structure, eliminating the traditional component water retaining plate, this The design can greatly reduce the running resistance (about 150Pa) and the running energy consumption, which is more energy efficient. Our patent number is: L01246496.1
 
The fan adopts international brand, high intensity and low noise. The fan impeller and the air collection port are sprayed with anti-corrosion coating to enhance the corrosion resistance of the fan. The damping spring is used to reduce vibration, and the vibration damping efficiency is up to 95%. The motor adopts variable frequency motor and imported bearings. The protection grade is IP55 and Class F insulation.
 
The medium efficiency filter is a bag filter of Class F (EN779), the frame is made of aluminum alloy frame, and the joint seal is sealed. The filter material is hot-melt formed by ultra-fine synthetic fiber, which has a large dust holding capacity and a filtration efficiency of 90%. Above (colorimetric efficiency). Brand: Dong Fu Long Dehui
 
Dongfulong Dehui Certification Department has 12 GMP verification engineers from major pharmaceutical companies with 6 years of work experience per person. So far, we have provided verification and debugging services for hundreds of customers, and passed FDA, EUGMP, WHO, China 2010 GMP.
