Central Air Conditioning Terminal Products

Description

The ZK series air handling units are air treatment equipment developed by our company based on years of experience in producing central air conditioning systems, incorporating both domestic and international advanced technologies. These units can perform various functions such as mixing, filtering, cooling, dehumidifying, and heating the air. The units are available in various specifications to meet different capacity requirements, with air volumes ranging from 3000 to 250,000 m³/h and external static pressures up to 2000 Pa. They can also be custom-made according to project design requirements. The modular air handling unit profile uses patented high-strength dual-chamber cold bridge design profiles, high-density rigid polyurethane panels with a thermal conductivity of U = 1.4W/m²·K. The thermal performance meets the European EN1886:2007 T3 standard. High-strength insulation materials form a thermal bridge to prevent condensation under high temperature and humidity environments.
The unit frame and panels, as well as the seams between panels, adopt a double-S sealing design, increasing air duct turns and wind resistance to effectively eliminate air leakage. According to the National Air Conditioning Equipment Quality Supervision and Inspection Center, the actual air leakage rate is 0.1%, far below the national standard value.
The cooling coil uses high-quality deoxidized phosphor bronze tubes with aluminum fins. The copper tube ends are mechanically expanded using dedicated mold tools, and the aluminum fins are mechanically stamped, using a secondary flanging process. The mechanical expansion and copper tubes tightly bond to significantly improve heat transfer while preventing dust accumulation and making cleaning easier, thus preventing bacterial growth on the fins.
The unit is equipped with high-efficiency, low-noise, dual-inlet, multi-blade centrifugal fans specifically designed for air conditioning systems. These fans offer high efficiency, low noise, and stable operation.
The internal functional components are quality-assured, with long-term supply agreements with suppliers to ensure stable product performance.
The design, production, and sales of the product are strictly conducted according to the ISO9001 quality assurance system.
The modular design of the unit makes selection easy, and the flexible combination of functional segments allows for convenient transportation, assembly, and maintenance.
For different types of air conditioning systems and heat-humidity treatment solutions, the most optimal control schemes can be flexibly adopted based on customer requirements.
