Outdoor Electrical Cabinet Air Conditioner

Product Range and Application Fit

As a Wholesale Outdoor Electrical Cabinet Air Conditioner Suppliers, Company, Exporter, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.

The standard SAD series is arranged by cooling capacity at 35 °C ambient and 35 °C cabinet temperature. All models operate from -40 °C to +55 °C ambient, which is the operating window we design around for outdoor installations.

Engineering Value and Configuration Approach

Our engineering team matches the cooling capacity to the real cabinet heat load, not just enclosure volume. For outdoor projects we also review solar gain, night-time temperature drop, condensation risk and the available mounting surface. The result is a configuration that keeps electronics inside the specified temperature band while avoiding short-cycling and over-cooling.

• Closed-loop air paths prevent dust, moisture and insects from entering the cabinet.
• Self-draining condensate evaporation eliminates external drain piping.
• Optional internal heater prevents coil freezing below 0 °C.
• Concealed mounting screws improve field security and theft deterrence.
• Powder-coated steel with stainless steel fasteners for long outdoor life.

Critical Specifications and Performance Data

Standard models are rated per ISO 5151 at 35 °C dry-bulb inside and outside the cabinet. Capacity tolerance is ±5%. Cabinet protection is IP54 for the electrical connections and IP55 for the whole unit, tested against water jets and dust ingress per IEC 60529.

Controls, Monitoring and Automation Integration

Every unit includes dual temperature sensors on the inlet and return air paths. Select models use inverter-driven compressor modulation to match cabinet load and reduce energy consumption. For site monitoring integration, the unit provides potential-free alarm contacts and an RS485 Modbus RTU interface for real-time status and fault diagnosis.

We can configure the control logic to work with your BMS, SCADA system or remote telemetry unit. Alarm thresholds, sensor positions and communication settings are defined during the proposal phase so the unit arrives ready for site integration.

Installation, Maintenance and Acceptance

Correct installation is critical for outdoor performance. We support the mounting layout with clear clearance requirements and electrical guidance for AC and DC installations.

• Mount within ±5° vertical on the cabinet side or roof; condensate drain plug faces downward.
• Keep 300 mm clearance at the condenser intake and 500 mm at the hot air exhaust.
• Size power cables per NEC or local code; use copper conductors with 90 °C-rated insulation.
• For DC units, connect the battery bank with a fuse rated at 1.5× running current within 500 mm of the unit.
• Clean evaporator and condenser coils every 3 months with a soft brush or vacuum, never high-pressure water.
• Replace the desiccant filter-dryer every 2 years or when pressure drop exceeds 0.5 bar across the liquid line.

All service work must be performed by certified refrigeration technicians with refrigerant recovery per local environmental regulations. Our quality process includes inspection after each production stage and full inspection of finished products according to customer requirements and international standards.

Information We Use to Configure Your Solution

To prepare a precise quotation and technical proposal, we need the operational context of the enclosure, not just a model number. The following inputs define the configuration we supply:

• Enclosure dimensions, mounting side or roof, material and existing cut-out constraints.
• Installed equipment heat load, including future expansion or seasonal load variation.
• Site ambient temperature range, solar exposure, wind-driven rain and salt spray risk.
• Required power supply: 24 V DC, 48 V DC or 110–230 V AC with frequency.
• Control and monitoring interface: potential-free alarms, RS485 Modbus RTU or custom protocol.
• Cabinet target temperature setpoint and allowable temperature band.
• Special requirements such as low noise, anti-corrosion coating, heater option or custom dimensions.

For quantities above standard wholesale volumes, we coordinate the production plan, packaging and delivery schedule directly with your project team. Our nearly 20 years of experience in overseas projects supports B2B customers with one-stop solutions from design to after-sales service.
