Flame Proof Split AC in Abu Dhabi | Split Air Conditioner Suppliers
The ATEX Split Air Conditioners for Zone 2 and Zone 22 Hazardous Areas provide reliable cooling and heating for industrial rooms exposed to flammable gases, vapours, or combustible dust. As a dependable Flame Proof Split AC in Abu Dhabi, the system supports technical rooms, analyser shelters, battery rooms, laboratories, production areas, control centres, and modular industrial buildings.
The complete system consists of an indoor evaporator unit and an outdoor condensing unit connected through refrigerant piping and electrical controls. Depending on the area classification, only the indoor unit, only the outdoor unit, or both sections can be supplied in an explosion-protected configuration.
Available systems cover cooling capacities from approximately 2.0 kW to 25.0 kW. Wall-mounted, ceiling-suspended, cassette, and ducted indoor units allow the system to suit both compact technical rooms and larger industrial buildings. Special high-ambient models can continue operating in outdoor temperatures up to approximately +52°C, making them suitable for Abu Dhabi and other hot-climate locations.
Atex Hub supplies these ATEX split air conditioners across Abu Dhabi, Dubai, Sharjah, the UAE, Saudi Arabia, Qatar, Kuwait, Bahrain, Oman, Europe, Africa, and worldwide for hazardous-area HVAC and industrial climate-control projects.
What Is an ATEX Split Air Conditioner?
An ATEX Split Air Conditioner is an explosion-protected cooling and heating system developed for rooms located in classified gas or combustible-dust environments.
The indoor section draws warm room air across an evaporator coil and returns conditioned air to the space. The outdoor unit contains the compressor and condenser, which transfer the absorbed heat to the outside environment.
Standard air conditioners include relays, motors, electrical contacts, printed circuit boards, switching devices, capacitors, and other parts that may create sparks or hot surfaces. An Explosion Proof Split AC Unit includes suitable protection measures to control these potential ignition sources.
These systems can support Zone 2 gas environments and Zone 22 combustible-dust environments, depending on the selected certification and indoor/outdoor unit arrangement.
Key Features of the Flame Proof Split AC
The Flame Proof Split AC combines hazardous-area protection with flexible indoor-unit designs, broad cooling capacities, and high-ambient operation.
- Zone 2 gas protection: Suitable configurations support industrial spaces where explosive gases or vapours are unlikely during normal operation.
- Zone 22 dust protection: Selected systems support areas where combustible dust clouds may occur only occasionally and for short periods.
- Wide cooling range: Available capacities extend from approximately 2.0 kW to 25.0 kW.
- Four indoor-unit styles: Choose wall-mounted, ceiling-suspended, cassette, or ducted arrangements.
- High-ambient option: Special configurations can operate in outdoor temperatures up to approximately +52°C.
- Cooling and heating: Heat-pump operation provides year-round room-temperature control.
- Flexible ATEX arrangement: The indoor unit, outdoor unit, or complete system can receive hazardous-area protection.
- Long refrigerant piping: Selected models support pipe runs up to approximately 85 metres.
- Large vertical separation: Suitable systems allow height differences up to approximately 30 metres between indoor and outdoor units.
- Inverter control: Selected series adjust compressor output according to room cooling demand.
- Technical cooling capability: Continuous-duty models support rooms containing heat-generating instruments and electrical equipment.
- Corrosion-protection options: Coated heat exchangers and durable finishes suit coastal, offshore, and industrial locations.
How the ATEX Split AC System Works
The indoor fan draws warm air through a return filter and directs it across the evaporator coil. Refrigerant inside the coil absorbs heat, while the indoor fan distributes cooler air back into the room.
The heated refrigerant moves through copper piping to the outdoor unit. The compressor increases its pressure, and the condenser releases the collected heat into the external air.
During heating mode, the refrigeration cycle reverses. The indoor coil releases heat into the room, while the outdoor section absorbs heat from outside.
The indoor and outdoor sections can be configured according to the actual hazardous-area layout. For example, an explosion-protected indoor unit may operate inside a classified room while the standard outdoor unit remains in a safe area. Where both locations are classified, both sections can receive the required protection.
Available ATEX System Configurations
The complete split system can be arranged according to the classification of the indoor and outdoor installation areas.
- ATEX indoor unit with standard outdoor unit: Suitable where the conditioned room is classified but the condenser sits in a non-hazardous outdoor area.
- Standard indoor unit with ATEX outdoor unit: Used where the indoor space is safe but the outdoor condenser location falls inside a classified area.
- ATEX indoor and outdoor units: Provides a complete hazardous-area system when both locations require explosion protection.
This flexibility helps reduce project cost because only the equipment installed in the classified area requires the relevant ATEX modification.
