Polyurethane panel

Frame structure

The frame structure adopts the concept of cold bridge design.

The internal surface of the unit is smooth and smooth, and it is not easy to accumulate dust, which is suitable for the use of purification system.

The unit adopts modular design, the size modulus is 100mm, and the overall size of the unit is increased or decreased by a multiple of 100mm.

Panel

The panel adopts a double-layer sandwich sandwich structure, the panel is surrounded by special aluminum profiles, excellent heat insulation performance, and makes the panel have excellent strength.

The interior of the panel is made of polyurethane foam material with a foam density of 48kg/m³, which can effectively prevent the transfer of cold energy.

The standard configuration of the panel is double steel plate inside and outside, and stainless steel plate and other materials can be selected according to the requirements.

Panel thickness of 25mm, 50mm two options are available.

Good sealing, low air leakage rate

The skeleton and the panel are double sealed, and the sealing material is rubber, which has good elasticity and anti-aging properties.

Seal rubber is hollow design, with positive and negative pressure follow-up, both positive and negative pressure have self-compression function.

The panel is made of special aluminum alloy and is fixed on the frame by screws, which is firm and reliable.

Unit box under 1000Pa standard working conditions, the air leakage rate is less than 1%.

High heat transfer efficiency

The heat exchange coil is made of seamless copper tube and aluminum fin, tightly combined with the expanded tube.

Coil standard is available in 2-12 rows, aluminum fin standard is 2.5mm, other pitch specifications are also available.

The selection calculation program can optimize the parameters such as the number of rows, sheet spacing and circuit number of coils under the required working conditions to ensure that the actual use needs are met.

The unique coil layout design ensures thorough drainage and prevents coil freezing cracks to the maximum extent possible.

Water tray

The surface cold coil is equipped with a condensate pan, dry V-shaped design, with drainage slope, to ensure the smooth discharge of condensate water. External insulation is applied to prevent condensation.

Smooth running. Low noise

Fan selection of domestic or international famous brand products.

DIDW double intake, double wide distance high efficiency low noise centrifugal fan.

Fan bearing selection of famous brand products, with self-aligning and self-locking function. The wind balancing accuracy reaches G4.0, greatly extending the service life of the bearing.

Fan selection software can select high-efficiency fans according to actual operating conditions. Ensure that the fan is operating at an energy-efficient "operating condition" point.

Fan drive

Standard V-belt transmission structure, and the use of Taper Lock tight hoop bushing pulley and import narrow V-belt, narrow V-belt wide bevel structure makes it have higher transmission efficiency and service life.

Electric machine

Selection of famous brand three-phase squirrel-cage type influenza motor, IP54 protection grade, F class insulation. The motor is placed inside the fan section and is jointly installed on the shock absorber bracket with the fan. The motor is equipped with an adjusting device to adjust the tightness of the belt.
