Explosion Proof Split AC in Sharjah | Split Air Conditioner Suppliers
The Explosion Proof AC Split Systems Ex ic nAC IIB T3 Gc provide dependable cooling and heating for technical rooms, process shelters, battery rooms, laboratories, and occupied spaces located in hazardous industrial environments. As a reliable Explosion Proof Split AC in Sharjah, the system combines an explosion-protected indoor unit, outdoor condensing unit, compatible controller, and certified electrical protection measures.
The wall-mounted split configuration supports Zone 2 gas and vapour environments under the equipment marking II 3G Ex ic nAC IIB T3 Gc. Standard systems operate from a 230 V, 50 Hz electrical supply, while 60 Hz configurations can support selected international projects. Cooling capacities are available for compact equipment rooms as well as larger industrial shelters.
The split design places the compressor and condenser outside the conditioned room. This reduces indoor noise, saves floor space, and simplifies independent temperature control. Atex Hub supplies these explosion proof split AC systems across Sharjah, Dubai, Abu Dhabi, the UAE, Saudi Arabia, Qatar, Kuwait, Bahrain, Oman, Europe, Africa, and worldwide for hazardous-area HVAC projects.
What Is an Explosion Proof AC Split System?
An Explosion Proof AC Split System is an air-conditioning arrangement modified and protected for use in classified environments where flammable gases or vapours may occasionally occur.
The system consists of an indoor evaporator and an outdoor condensing unit. Refrigerant pipes, electrical cables, controls, and condensate drainage connect the two sections. During cooling, the indoor coil absorbs heat from the room, while the outdoor unit releases that heat into the surrounding air.
A conventional split air conditioner contains electrical contacts, motors, relays, capacitors, circuit boards, and switching components that may create sparks or hot surfaces. An ATEX Split AC Unit uses approved protection measures to control these potential ignition sources.
The protection marking Ex ic nAC IIB T3 Gc identifies the system’s hazardous-area design. It combines intrinsic-safety measures with non-sparking or enclosed electrical protection suitable for equipment used in Zone 2 gas atmospheres.
Key Features of the Ex Proof Split AC
These systems combine effective room cooling with practical hazardous-area protection.
- Zone 2 suitability: Designed for locations where an explosive gas atmosphere is unlikely during normal operation and, if it occurs, remains present only briefly.
- ATEX equipment category: The II 3G marking identifies equipment intended for industrial gas environments requiring Category 3 protection.
- Ex ic protection: Selected low-energy electrical circuits use intrinsic-safety principles appropriate for Equipment Protection Level Gc.
- nAC protection concept: Relevant electrical components use non-sparking or enclosed protection methods for Zone 2 operation.
- IIB gas-group compatibility: Suitable for industrial gases and vapours included within the approved IIB classification.
- T3 temperature classification: The certified configuration limits the permitted equipment surface temperature according to the T3 requirement.
- Cooling and heating operation: Heat-pump configurations provide year-round temperature control.
- Wall-mounted indoor unit: The compact evaporator saves floor space and distributes conditioned air throughout the room.
- Cassette option: Ceiling-mounted arrangements can support projects that require four-way air distribution.
- Industrial electrical options: Standard systems use 230 V and 50 Hz, with 60 Hz configurations available for selected requirements.
- Corrosion-protection options: Outdoor sections can use coated heat exchangers and suitable finishes for coastal and industrial conditions.
- Independent room control: Each system maintains the temperature of a dedicated room without requiring a large central HVAC installation.
Understanding the Ex ic nAC IIB T3 Gc Marking
The equipment marking provides important information about the intended operating environment.
- II: Equipment intended for surface industries rather than underground mining.
- 3G: Category 3 equipment designed for gas and vapour environments with the protection level normally required in Zone 2.
- Ex: Equipment includes explosion-protection measures.
- ic: Intrinsic-safety level suitable for Equipment Protection Level Gc circuits.
- nAC: Protection measures intended to prevent ignition during normal Zone 2 operation.
- IIB: Gas group covering many industrial gases and vapours with greater ignition sensitivity than IIA substances.
- T3: Temperature classification for the approved maximum equipment surface temperature.
- Gc: Equipment Protection Level normally associated with Zone 2 gas environments.
How the ATEX Split AC System Works
The indoor fan draws warm room air through a return-air filter and across the evaporator coil. Refrigerant inside the coil absorbs heat, allowing the unit to return cooler air to the room.
The heated refrigerant travels through insulated copper pipes to the outdoor unit. The compressor raises the refrigerant pressure, and the condenser releases the collected heat outdoors. The refrigerant then returns to the indoor unit to repeat the cycle.
During heat-pump operation, a reversing valve changes the refrigerant direction. The indoor coil then releases heat into the room while the outdoor coil absorbs available heat from the external air.
Explosion-protection measures apply to the relevant electrical and mechanical parts. The final installation must retain the approved wiring, glands, isolators, enclosures, controls, and equipment markings.
