7. Complete functions: any combination of 18 functional segments. Can meet the different working conditions of all industrial enterprises
8. The distance between surface cooler and heater can be adjusted arbitrarily from 2.5mm to 5.0mm;
9. The unit can realize constant temperature and humidity control (equipped with automatic control system); its control accuracy is: temperature: ±0.1℃; humidity ±2%
10. Equipped with high-efficiency wheel-type energy recovery device, its heat recovery efficiency is over 70%.

2. Main features:
Reasonable design, beautiful appearance, convenient maintenance, straight lines, small volume, high strength, no cold bridge; modular design of siding, each siding can be folded arbitrarily, and high-pressure foaming of siding to ensure thermal insulation and strength;
Thermal insulation frame (patented technology)
The double-layer anti-cold bridge skeleton has excellent thermal insulation performance and high strength; the inner cavity of the skeleton is foamed at high pressure, which fundamentally eliminates the cold bridge around the skeleton.
High Efficiency Heat Exchanger
All the heat exchangers of our company are produced by OAK equipment in the United States. The unique equipment and unique process have created unique products!
The heat exchanger fin design and secondary flanging are OAK's housekeeping technology. On the one hand, it can increase the effective heat dissipation area, and on the other hand, the contact between the copper tube and the aluminum sheet is in the best state.
Composite filtration: (patented technology)
The use of primary effect plate type + medium effect bag type is called composite filter. The plate filter is made of imported nylon high polyester fiber and a unique process. The filtration efficiency of the composite filter is over 75%, second only to the high-efficiency filter. Second, the plate filter plays a role in filtration, which can effectively reduce the burden of the medium-efficiency filter, so that the service life of the medium-efficiency filter can be increased by more than five times. Third, the plate filter adopts the magnet "self-priming" fixing method, which makes the disassembly and assembly easy. Fourth, the plate filter is easy to clean and can be washed with high-pressure water guns and beaten with sticks; fifth, it has a wide range of adaptability and can resist the erosion of various harmful substances; sixth, it has strong reusability and can be cleaned more than 30 times.
Plate self-cleaning filter: (patented technology)
The automatic plate-type air filter unit is composed of a plate-type dust filter, a dust collector, a dust compactor, a dust-collecting fan and a PLC electric control system. The unit can be directly used as air-conditioning unit return air filter, without manual operation, fully automatic operation, saving a lot of labor, reducing the workload of operators. The unit is widely used in the threshing and redrying line, silk making line, coiling and bag workshop, and air-conditioning system in the process of wind wire feeding system in the tobacco processing industry. Filter and collect the dust of the air conditioning system to achieve the purpose of purifying the air.
Cartridge Filtration
The filter is widely used in the tobacco industry's silk production line, coiling and bag workshop. Donaldson Pulse Cleaning Cartridge Filters This cartridge provides excellent filtration performance. Especially adding a layer of ultra-fine PTFE fiber layer on the surface of ordinary filter material, the filtration efficiency can be increased by 10 times, and the efficiency of dust ≥ 0.5μm can reach 99.99%, and in the filtration of normal pulse cleaning, The resistance does not increase, so as to achieve the effect of energy saving
Wheel type full heat energy recovery device:
The surface of the rotary heat exchanger is honeycomb, and is coated with a layer of adsorbent material as a desiccant. Place the runner between the air conditioner boxes so that it divides into two parts. Exhaust air from an air-conditioned room exits from one side, and outdoor air enters from the other side in the opposite direction. In order to increase the heat exchange area, the wheel rotates slowly (10~12 rpm). One half of the wheel absorbs stored heat from the hotter air, and when it spins to the other side, it releases heat and transfers energy. The desiccant attached to the surface condenses the moisture from the high-humidity air, absorbs it through the desiccant, and when it rotates to the other side, releases the moisture into the low-humidity airflow. This process transfers latent heat.
Rotary wheel type total heat recovery device, its heat recovery efficiency is as high as 70% or more.
