As air-conditioner manufacturing lines grow more automated, end-of-line performance testing has become a critical control point for product quality, cooling and heating verification, and inverter stability. The ZDJ-2 semi-automatic performance test unit is designed for that stage of assembly. Its specifications and integration requirements illustrate the trade-offs factories weigh between throughput and measurement precision.
The ZDJ-2 is a specialized unit intended for end-of-line quality control on air-conditioner assembly lines. It simulates operating conditions to evaluate cooling, heating and inverter performance after assembly, allowing manufacturers to verify that finished units meet technical standards before shipment.
The system is positioned for factories that need to test multiple models on a single line. Its rated power is 0.5 kW, and it draws 380V AC at 50 Hz. The table below summarizes the published specifications.
| Parameter | Specification |
|---|---|
| Model | ZDJ-2 |
| Rated power | 0.5 kW |
| Input power | 380V AC / 50 Hz |
| Core functions | Cooling, heating and inverter performance testing |
| Application | Air-conditioner assembly lines |
Foshan Dongliu Automation Technology, which has worked in air-conditioner assembly lines and auxiliary equipment for more than eight years, supplies the ZDJ-2 alongside a broader equipment set. That lineup includes roller, chain-plate and belt conveyors, vacuum pump units, leak detectors and refrigerant charging machines, allowing a factory to source assembly and test equipment from one supplier.
The supplier provides factory acceptance materials including equipment test reports and video inspection. Warranty coverage of one year applies to core components such as the PLC, transmission gears and pumps. OEM and customized designs are available, and the supplier offers on-site installation, commissioning and operator training so the unit can be absorbed into an existing production rhythm.
Because industrial test equipment is delicate and heavy, the ZDJ-2 is packed in export-standard wooden cases. Shipments currently leave through the ports of Shenzhen or Guangzhou.
Factories receiving the unit should confirm that the installation area has a stable 380V AC supply and enough space for commissioning. Those site conditions are typically checked before delivery to avoid delays when the equipment arrives.
