Introduction
Lark Air Handling Units(AHU) are designed with high quality and efficiency to meet the most demanding requirements. They provide cooling, heating and ventilation to conditioned space. These units are suitable for hotels, hospitals, large halls, banks, super markets and other applications.
The advantage of modular design
Lark Air handling unit are manufactured in modular sections, where each module contains one or more components. Several modules compose a unit.
The whole air handling unit is shipped completely assembled as standard but partially assembled units can be shipped as an option.
The flexible modular design allows various section arrangements according to the task requirement.
1) Wide capacity range (1500m3/h to 40000m3/h). Larger capacities can be made as special units.
2) Ideal selection for controlling the indoor air quality so that the right degree of filtration, humidification, cooling, heating and also noise level can be achieved.
3) High efficiency centrifugal fans, excellent vibration absorption and high efficient heat exchangers are integrated to ensure reliable performance of the unit.
4) Air tight construction.
5) Rugged base frame adds strengths to the unit rigged construction.
6) High efficiency with high quality materials and components.
7) Long life with easy inspection and maintenance through access doors and access panels.
8) Different kinds of accessories and options can be selected and added to this modular design.
9) Modular design unit is suited to match application requirements.
10) 30mm to 50 mm thickness foaming material, strong boday and well heating insulation
Outstanding features
Design Versatility
Unit capacities in AHU have a wide range depending on the design requirements, also units can be constructed almost in any shape and dimensions to meet client's restricted spaces in mechanical room, roof...etc.
Structure quality
All frames are made of high quality extruded metal profile, and the frame rigidity is achieved through the use of a special construction.
This rigid structure supports the whole unit to prevent bends due to external loads.
Service ability
The unit construction facilitates easy accessibility for operators to maintain and service. This accessibility is reflected in the number of doors provided for the unit and easy removing panels.
This serviceability will positively affect the unit expected life.
Options diversity
There is a vast variety of filtration, cooling, heating fan, and controls options that can be provided for AHU series, which enhance our unit's performance.
Plese contact us for more detailed technical specification or send us your detailed requirement. Besides water system, we also can do DX type AHUs, please feel us know your project information, we will try our best to support.
