The Winnex Air rooftop explosion-proof air conditioner is designed and manufactured in strict accordance with ATEX Directive 2014/34/EU and the EN 60079 series, and holds an explosion-proof certificate issued by an authorized explosion-proof electrical product inspection body. Explosion-proof marking: Ex db ib mb IIC T4 Gb. The unit serves explosive hazardous locations in the petroleum, chemical, electric power, military and pharmaceutical industries, suitable for Zone 1 and Zone 2 areas where explosive atmospheres formed by Group ⅡA, ⅡB, ⅡC flammable gases or vapours and temperature classes T1–T4 mixed with air may exist. Engineered specifically for outdoor rooftop duty, the unit requires no dedicated machine room and occupies no indoor floor area, making it a rooftop explosion-proof air conditioning solution for centralized air treatment in hazardous-area plants, process units and supporting workshops.

Key Features

●        Outdoor rooftop installation frees up indoor space. Designed for outdoor duty, the unit can be installed directly on the plant roof without a dedicated explosion-proof machine room, occupying no usable indoor floor area. Packaged or split configurations are available according to project conditions, allowing flexible equipment layout and duct routing for both new-build projects and rooftop retrofits of existing plants.

●        Free combination of functional sections for centralized air treatment. Cooling, heating, dehumidification, humidification and purification sections can be combined as required to deliver centralized air conditioning for hazardous-area plants, reducing the crossed piping and multiple maintenance points associated with dispersed equipment.

●        Return-air and full-fresh-air configurations. The series includes return-air and full-fresh-air models in multiple specifications, allowing selection based on site conditions and air-change requirements. For locations with accumulation risk of harmful gases or high air-change requirements, full-fresh-air models support explosion-proof compliance while maintaining indoor air quality.

●        Internationally recognized core components for efficient, stable operation. Brand-name scroll or screw compressors, low-noise explosion-proof fans and Danfoss expansion valves are specified to ensure reliable performance, stable operation and favorable energy efficiency under continuous industrial duty.

●        Microcomputer intelligent control with simple human-machine interaction. A user-friendly microcomputer control system with an intuitive interface enables precise management of temperature, humidity, operating mode and unit status. Built-in fault self-diagnosis and alarm functions help maintenance personnel locate abnormalities quickly and shorten troubleshooting downtime.

●        Comprehensive multi-layer safety protection. Power protection, delayed start, high/low pressure protection, overheat protection, overload protection and short-circuit protection work together to mitigate equipment fault risks and support long-term continuous operation in hazardous areas.

●        Strong overall performance and easy maintenance. The unit combines energy efficiency, low noise, rich functionality, dependable quality, stable performance and simple operation, reducing later maintenance workload for continuous industrial operation.

Engineering Considerations for Rooftop Installation

Selecting a rooftop explosion-proof air conditioner involves more than matching cooling capacity; installation and maintenance conditions must be confirmed at the same time. Roof load capacity and base design should be verified during the structural design stage, and vibration isolation measures between the unit and its base should be provided to reduce transmission of operating vibration into the building structure. Duct penetrations through the roof require proper waterproofing and fire-stop sealing, and the relationship between penetration locations and hazardous-area boundaries should be confirmed. The maintenance access side of the unit should face a safe area or be provided with a service walkway, so that filter replacement, electrical inspection and refrigerant connection work involve as little time as possible inside classified areas. For rooftop retrofits of existing plants, roof load margin, lifting access and power supply routing should be checked during selection to avoid rework later.
