AHU-VAQ Series

Introduction
The VAQ series air handling units have been developed and manufactured for years with advanced Italian technology to meet the requirements of clients. The unit features novel structure, attractive appearance, flexible assembly, stable operation, complete function, and easy installation and maintenance. The parts all utilize famous brands. The molds and equipment are all exported from Italy.

Application
The air handling units have many functional sections: air supply, cooling, heating, humidify, dehumidify, air purify and silencing. The units are used in the air systems of many industries like mechanical, electronic, textile, medical,

metallurgy, chemical, energy and food, etc. The units are ideal for restaurants, office buildings, hospitals, theaters, supermarkets etc. The user can choose the most economic and optimized functions with software according to client requirements.
Selection by Software

Various Functional Sections
The air handling unit has the following sections: mixing section, preliminary filter section, medium filter section, sub HEPA filter section, HEPA filter section, cooling coil section, humidifier section, heating section, sterilization section, sound attenuator section, heat recovery section, air return section, air supply section, air discharge section, and so on.

Low Noise
The air handling unit uses a double inlets forward curved centrifugal fan motor, strict static and dynamic testing has proved its stable and low noise operation. The world brand fan bearings used are hermetic style, so there is no need for charging lubrication oils and any other maintenance since it can auto-lubricate, auto-adjust core, auto-lock, anti-shuttle, etc.

Quality Components Selection
1. It has a famous fan, high efficiency and low noise.
2. It offers a 3Phase asynchronous (induction) motor with protection level IP 55 and insulation level F.
3. A drop eliminator will be used when face velocity is higher than 2.5m/s. and it can be galvanized steel, aluminum alloy, stainless steel, ABS material, FRP and wet film, according to client's requirement.
4. It has a preliminary panel filter at G4 class, or low velocity preliminary bag filter at class G4, medium bag filter made of melt-blown non-woven web or import glass fiber, small resistance, filtering class up to F5, F6, F7, F8, dense fold style sub HEPA filter, filtering class up to F9, F10.

Optional Accessories/Function
Optional Devices
Several automatic control items are optional for the air handling unit according the client's requirement, such as temperature and humidity controller at air supply and air return section, anti-freezing control, filter blocking control, fresh air damper and fan motor simultaneous control, indoor/outdoor temperature difference compensation energy saving control, building management system control, etc.
Optional Variable Air Flow Function
VICOT uses an asynchronous three phase motor with characteristic pressure adjustment and speed change, then the AHU changes its air flow and saves energy by the inverter speed adjuster. It can be a constant air flow AHU without pressure adjuster. The inverter speed regulation structure is simple and practical; it has its own soft starter, less impact to electricity facility when the motor starts. The inverter speed adjuster can change the speed steplessly to change air flow and save energy according to the temperature/humidity detected at indoor temp. and humidity sensor. We use an inverter from DANFOSS, ABB, SIEMENS, etc. According to the design, a relative control-box can be equipped which has the following functions: total pressure and star triangle start and stop, phase missing, overload, uneven phases, electrical protection, motor over heat, over current, and malfunction alarm ,etc.
