1300 W
Cooling capacityIP54
Enclosure rating45 dB
Sound level20 kg
Unit weightThis air conditioner is specifically designed for PLC cabinets housing programmable logic controllers, industrial computers, and automation components. The unit delivers 1300W of cooling at 35°C ambient with a sealed rotary compressor and efficient microchannel condenser. The compact 160mm depth allows installation in standard PLC enclosures.
The IP54-rated steel enclosure protects against dust and water splashes common in factory environments. The integrated digital controller features an LCD display, alarm outputs, and Modbus RTU communication for seamless integration with automation systems. The unit includes a condensate evaporation system that eliminates external drainage in most installations.

PLC-Focused Advantages
PLC Integration Ready Modbus RTU communication standard. Dry-contact alarm outputs. Compatible with Siemens, Allen-Bradley, Schneider Electric, and other major PLC platforms.
Precise Temperature Stability Maintains cabinet temperature within ±1°C of setpoint. PID controller with ambient feed-forward compensation ensures stable PLC operation.
Factory Floor Ready IP54 protection against dust and water splashes. Vibration-resistant construction. Operates in ambient temperatures up to 50°C.
Ultra-Quiet Operation 45 dB(A) sound pressure at 1m. EC fans with variable speed control reduce noise during low-load conditions in production areas.
Product Features
Rotary Compressor Hermetically sealed with built-in overload protection. Vibration-isolated mounting reduces noise transmission to the PLC cabinet.
Microchannel Condenser Aluminum microchannel coil with hydrophilic coating. Dual-speed fan with automatic pressure control for consistent performance.
Digital Controller LCD display with keypad. Supports setpoint 10-45°C. Alarm history stores last 30 events. Modbus RTU communication standard.
IP54 Enclosure Galvanized steel with powder coating. Sealed cable glands. Suitable for factory floor and industrial environments.

Frequently Asked Questions
The unit integrates with all major PLC platforms via Modbus RTU. Compatible with Siemens SIMATIC, Allen-Bradley ControlLogix, Schneider Electric Modicon, Mitsubishi, and others. The dry-contact alarm outputs provide simple integration with legacy systems.
The unit maintains cabinet temperature within ±1°C of setpoint using a PID controller with ambient feed-forward compensation. This ensures stable operating conditions for sensitive PLC and automation components.
Condensate collects in a tray above the condenser. Heat from the condenser evaporates the moisture, eliminating external drainage in most installations. Optional drain kit available for high humidity environments.
Clean air filters every 2-3 months in factory environments. Inspect condenser coil quarterly for dust accumulation. Check refrigerant charge annually. All service points are front-accessible for easy maintenance.
Yes. The compact 160mm depth and universal mounting brackets are designed for retrofit installation. A mounting template is provided for accurate cutout positioning on existing PLC cabinets.
The unit operates from -10°C to +50°C ambient. The crankcase heater ensures reliable startup in low temperatures. Above 40°C, the controller modulates compressor speed to maintain cooling performance.
