CNWINNEX Atex Certified Hazardous Area Zone 1 & Zone 2 Explosion-Proof Ducted Air Conditioning Unit | Concealed Ducted Explosion Proof AC for Hazardous Areas
CNWINNEX Atex Certified Hazardous Area Zone 1 & Zone 2 explosion-proof ducted air conditioning unit is engineered and manufactured with advanced explosion protection technology, in strict compliance with ATEX Directive 2014/34/EU and the EN 60079 series explosion protection standards. Explosion-proof marking: Ex db mb IIC T4 Gb. It delivers high cooling and heating capacity with fast temperature response, acting as an intelligent industrial HVAC solution. The unit is suitable for Zone 1 and Zone 2 hazardous locations where flammable gas and vapour mixtures of Group ⅡA, ⅡB, ⅡC and temperature classes T1~T4 may exist.
The indoor unit adopts a framed structure with an LCD display panel and ultra-low noise design for quiet operation. It supports fully automatic operation, automatic fault diagnosis and programmable on/off settings for easy maintenance. The indoor unit can be concealed and hoisted inside the ceiling space, saving installation space without occupying floor area and preserving the overall indoor appearance. Connected with supply air ducts, the unit allows multiple air outlets within the room. A high static pressure version is available for long-distance air delivery. The outdoor unit can be flexibly mounted on rooftops, balconies or external support frames.
Equipped with a branded expansion valve, the unit flexibly adjusts refrigerant flow according to thermal load for reasonable and efficient operation. The heat exchanger uses inner grooved copper tubes and hydrophilic aluminium fins to achieve high heat transfer efficiency. The unit features rapid temperature sensing and accurate temperature regulation with well-distributed airflow. Fresh air intake is supported to improve indoor air quality and maintain a healthy, stable working environment.
Key Product Advantages
● Concealed ceiling mounting saves space and keeps indoor appearance neat; multi-outlet air distribution via ducts, with high static pressure option for long-distance air supply
● Manufactured in compliance with ATEX Directive 2014/34/EU and EN 60079 series standards, marked Ex db mb IIC T4 Gb, qualified for Zone 1 and Zone 2 explosive hazardous areas
● Microprocessor full automatic control, auto fault check, multi-layer safety protection for stable, safe and simple operation
● High-efficiency heat exchange components, fast cooling and heating, optional fresh air intake to enhance indoor air quality
● Waterless system, simpler site construction and lower installation investment
Typical Applications
Chemical workshops, oil & gas control rooms, pharmaceutical explosion-proof clean rooms, hazardous goods warehouses, explosion-proof laboratories and other hazardous areas containing flammable gas or vapour explosive mixtures.
A low-noise explosion-proof centrifugal fan is fitted on the indoor unit, featuring reliable explosion-proof performance, large air volume and low sound level. Controlled by a microprocessor, the unit automatically adjusts operating status with all parameters pre-set before delivery for immediate commissioning. It integrates multiple protections including overload, overcurrent, high/low pressure, phase sequence, phase loss and time delay protection, as well as temperature readout, fault indication, anti-cold-air and overheat protection for simple and safe operation. No water system or terminal equipment is required, which effectively reduces installation cost.
