FEATURES

Instruction

Patented StructuralExcellent Quality

Air handling compartment applied patent design structure with the 0.19% super low air leakage ratio. The unit uses panel’s direct fixing structure and the internal of the panel comprise of high density of injected rigid polyurethane foam that ensure the strength of the panel.

Patented structural combination type air handing unit applies  standard module design. Every module is 310mm length. unit assembly’s height and width can be adjusted accordingly with a module ratio to suit the design condition requirement. Outdoor unit are using double system or multi-systems to execute multi steps capacity regulation in order to cut down the operation cost. Multi-systems are all individual independent systems, units still operating without breaking down although one of the systems failed.

Flat internal, clean room application

 Again patented structure provides our AHU product with a good smooth surface of the unit which makes dust collection hard and not easy to be polluted. Thus it is suitable for clean room application.

Aesthetic Outlook and Fission Design

Unit panel uses high strength pre-painted steel as its external skin. The pre-painted steel has an antirust properties and is covered with a protection plastic layer to prevent any scratcher during assemble and transportation. After the panel is constructed, the corner becomes an arc structure thus providing an aesthetic outlook.

Site Installation Easy and Fast Handling

The entire panel of the unit is constructed using bolt and nut fastening, it permits the equipment to be easily assembled or dismantle on the job site. Frequent assemble and dismantle will not affect the effectiveness of air tight and structural integrity of the unit. The equipment can be delivered according to customer requirement

Super Silent, Quiet Operation

Utilization of latest technology full/semi closed hermetic screw compressor, resulted in a consistent reliable operation performance with low vibration and noise.

The unit utilizes low speed fan and semi hermetic compressor enveloped with a layer of sound absorption sponge for noise isolation.

The high performance low noise propeller fan blade with high efficiency fan motor has been selected to prove an effective air dynamic performance.

High quality, Reliable Performance

All System components are using world branded HVAC components such as ALCO, DANFOSS, SANYO, etc which are of high quality and reliability, while the electrical control components are of PUMP,SIEMENS and etc manufacturer supplies parts.
