Roof-Mounted Air Conditioner for Electrical Enclosures (Indoor Use) | JXCooling
JXCooling roof-mounted enclosure air conditioners are designed for indoor electrical cabinets and PLC control panels on production lines. Installed on the top of the enclosure, the unit delivers stable, sealed-loop cooling while saving cabinet interior space—ideal for compact cabinets with dense wiring, terminal blocks, and high component loading.
With reliable cooling capacities of 1.0kW / 1.5kW / 2.0kW, standard RS485 communication, and IP54 protection, JXCooling roof-mounted units help prevent overheating trips, reduce thermal stress, and extend the life of PLCs, power supplies, drives, and communication modules in continuous-duty industrial environments.
Key Advantages
Top-Mounted Design — No Cabinet Space Occupied
Roof installation keeps side panels and cabinet interior clear, improving wiring layout and service access.
Stable Cooling for Production Lines
Efficient refrigeration maintains a consistent cabinet temperature to protect sensitive electronics and improve uptime.
Monitoring-Ready (Standard RS485)
RS485 communication is standard for remote status monitoring, alarms, and maintenance efficiency.
Typical Indoor Applications
PLC control cabinets on automated production lines
Electrical control panels for conveyors, packaging lines, and robotic cells
Drive cabinets (VFD/servo) for machinery and assembly equipment
Process control cabinets in food & beverage plants
Textile machinery control cabinets and automation enclosures
Industries: automotive, food processing, textile manufacturing, machinery & automation.

How to Choose the Right Capacity
To select the best model, please provide:
Cabinet size (W×H×D) and installation space on the roof
Heat load (W) or equipment list (PLC, drives, PSUs, etc.)
Workshop ambient temperature range
Target cabinet internal temperature
Drain requirement (standard drain or waterless option)
RS485 integration needs (addressing/protocol requirements)
Quick guidance:
1.0kW: small PLC cabinets, moderate heat load
1.5kW: standard production-line control cabinets
2.0kW: higher heat load cabinets with drives/servo systems
Installation Notes (Indoor)
Ensure roof rigidity and sufficient clearance above the unit for condenser airflow
Seal the cut-out properly to maintain cabinet protection and reduce air leakage
Route power and RS485 cables separately from high-noise power lines
If using the waterless device, follow recommended airflow and clearance guidance for best evaporation performance
Maintenance
Clean condenser fins / dust screens periodically (based on workshop dust level)
Check RS485 status and alarms during planned maintenance
Inspect condensate handling path (or waterless module condition) regularly
