AHU Features
Humidification section
- ● Dry steam humidifier: isothermal humidification, made of stainless steel, corrosion resistance, small size, easy installation, clean humidification, high humidification efficiency, electric and manual are available. Suitable for humidification situations with steam source.
- ● Electrode humidifier: Use AC power to process tap water to produce clean steam, microcomputer control, it has two control methods: proportional adjustment and switch adjustment. Suitable for process humidification situations without steam source.
- ● Vaporizing (wet film) humidifier: Use wet film material to absorb water, air flow through the wet film to evaporate and vaporize, can wash and filter the air at the same time, also can be used as water baffle. It can use direct water supply or circulating water.
- ● High-pressure spray humidifier: Tap water is pressurized and finely atomized through the nozzle, fine droplets evaporate and humidify in the air. When choosing high-pressure spray humidifier, humidification efficiency should be considered, generally is 40-50%.
Plate heat recovery device
- ● Fresh, exhaust air are heat exchanged in the plate-fin heat exchanger, according to different heat exchanger materials, can be divided into sensible heat exchanger and total heat exchanger, heat recovery efficiency＞60%.
- ● Plate-fin heat exchanger static installation, easy to arrange the air flow channel in AHU, to reduce AHU volume.
- ● Indoor and outdoor two-way ventilation, fresh and polluted air equal replacement, can achieve positive and negative pressure operation according to customer requirements. Fresh and exhaust air are completely separated to completely avoid cross contamination.
Intermediate media heat recovery device
● Intermediate media (usually water or glycol solution) flows in the intermediate
heat exchanger located in fresh, exhaust air system, is brought into fresh air through
exhaust air. It is used in air conditioning system with small temperature differences.
Can recovery sensible heat, heat recovery efficiency is about 50%.
Heat pipe heat recovery device
● Heat pipe heat recovery device is a kind of heat exchange element that use
phase change of working medium (such as ammonia, freon, etc.) to exchange
heat. Heat pipe heat recovery device has compact structure, adopts fully enclosed
design, high heat recovery efficiency and no loss.
Heater
● Optional steam coil, hot water coil, heat recovery coil, finned electric heating
pipe, burner or PTC electric heating pipe.
Fan system

- strict static & dynamic balance test, balance accuracy is not lower than IS01940-G4.0 standard.
- ·Fan uses tapered sleeve bearing to reduce vibration problem caused by eccentric lock bearing.
- All are imported brand bearings, service life is more than 75,000 hours under design condition.
- ·All fans have passed AMCA product performance certification to ensure high reliability.
- ·Low operating noise, high efficiency, solid structure and stable performance.
- ·Use professional CAD selection software to optimize design.
- ·Various specifications are available, can meet different air flow and pressure requirements.
- ·Fan can be volute free fan, EC fan, wing fan, direct connection fan, and single inlet fan.
Electronic purification
Dust removal and purification
·Ionize the suspended particles in the air through the purification electric field, use high
voltage electrostatic field to make all suspended particles in the air (minimum to 0.01
microns) attach positive charges, then quickly adsorbed by dust collecting plate to achieve
high efficiency dust removal and purification. Dust removal efficiency＞98.9%.
Sterilization and purification
·Discharge electrode produces plasma under high pressure, plasma will quickly destroy
and completely kill the cell nucleus of microorganisms such as bacteria, viruses and dust
mites in the air, residual materials will be sintered and adsorbed by the dust collecting
plate at the same time, sterilization efficiency＞99%, completely eliminate the reproduction
and spread of bacteria, viruses and infectious viruses, completely eliminate cross-infection.
Sterilization efficiency＞95%.
Rotary heat recovery device
- ·Overall winding+fixed spoke structure, solid and stable structure, can safely
- run in the range of -40C~ 120C, service life can reach more than 15 years,
- can be cleaned by high pressure air, water, steam, solution, etc.
- ·Heat recovery rate＞80%, small pressure loss.
- ·Total heat recovery & sensible heat recovery can be selected according to needs.
- ·Rotary heat exchanger speed is controlled at 10~12 RPM.
- ·Wheel core material is made of special alloy aluminum, high heat exchange
- coefficient, chlorine resistance, corrosion resistance and long service life.
- ·Adopt thickened aluminum foil, corrugated height is available in various
- specifications, wheel core honeycomb is triangle.
- ·High seal performance. Adopt double wear-resistant waterproof brush
- and rubber & plastic structure, high surface smoothness, tight seal, low air
- leakage rate. After adding double cleaning fan, mixing air rate can be
- controlled within 1%.
- ·Drive motor, lifelong lubrication, maintenance free, no need to add lubricating
- oil, insulation class F, protection class IP54.
- ·Drive belt has self-tensioning device, no need to adjust the belt length frequently.
