2200 W Cooling @ 35°C
IP66 Dust / water ingress
316L Stainless steel
R454B Low-GWP refrigerant
This air conditioner is purpose-built for outdoor cabinets deployed in harsh environmental conditions including coastal areas, desert climates, and heavy industrial zones. The unit delivers 2200W of cooling capacity at 35°C ambient, with a hermetically sealed scroll compressor and corrosion-resistant microchannel condenser coil.
The IP66-rated enclosure provides complete protection against dust ingress and high-pressure water jets, making it suitable for locations exposed to heavy rain, washdown procedures, and salt spray. The 316L stainless steel construction with epoxy coating ensures long-term durability in corrosive atmospheres. The system operates reliably from -40°C to +60°C ambient, with integrated crankcase heaters and low-ambient control logic.

Deployment Scenarios
01
Coastal & Marine - Equipment cabinets at port facilities, offshore platforms, and coastal monitoring stations exposed to salt spray and high humidity.
02
Desert Environments - Telecom and control cabinets in arid regions with extreme temperature swings, sandstorms, and high UV exposure.
03
Industrial Processing - Facilities with chemical exposure, washdown requirements, and airborne particulates from manufacturing operations.
04
Remote Infrastructure - Unattended sites in mountainous or arctic regions where equipment reliability is critical and maintenance access is limited.
Frequently Asked Questions
Q: Why is 316L stainless steel used for the enclosure?
316L stainless steel provides superior corrosion resistance in saline and chemically aggressive environments compared to 304 or galvanized steel. The low carbon content (L grade) reduces susceptibility to intergranular corrosion after welding.
Q: What is the difference between IP66 and IP55?
IP66 provides complete dust-tight protection and resistance to high-pressure water jets (100 L/min at 100 kPa). IP55 offers protection against dust ingress and low-pressure water jets. IP66 is specified for harsh environments with washdown or heavy rain.
Q: Can the unit withstand salt spray exposure?
Yes. The unit has been tested to 1500 hours of salt spray per ISO 9227. The 316L stainless steel, epoxy coating, and corrosion-resistant condenser coil provide protection against marine environment corrosion.
Q: What is the maximum ambient temperature for operation?
The unit operates continuously up to 60°C ambient. Above 55°C, the compressor speed is modulated to maintain safe operating conditions. Capacity is derated by approximately 8% per 5°C above 45°C.
Q: How is the unit protected against power surges?
The unit includes a Type 2 surge arrester on the power input. For lightning-prone installations, an external Type 1+2 surge suppressor is recommended at the main distribution panel.
Q: What maintenance is required in harsh environments?
Inspect condenser coil monthly in dusty or coastal areas. Clean with compressed air or low-pressure water. Check cable glands and enclosure seals quarterly. Replace air filters every 3-6 months depending on particulate load.
