Chemical and petroleum plants operate in some of the most dangerous environments on earth. Flammable gases, explosive vapors, and combustible dust make traditional air conditioning systems a serious liability.
A single spark from a conventional AC can trigger catastrophic explosions, leading to:
✔ Safety violations & regulatory fines
✔ Costly downtime from equipment failure
✔ Life-threatening accidents
Flameproof split ACs are the only safe solution—but choosing the right one requires careful planning. This guide breaks down the 5 critical factors to consider before buying.

Flameproof ACs are rated for specific risk levels:
Zone Type | Risk Level | Gas Presence |
Zone 1 | High Risk | Flammable gases likely (e.g., refineries, chemical reactors) |
Zone 2 | Moderate Risk | Gases are rare (e.g., storage areas, ventilation zones) |
❌ Never install an AC without the proper certification for your plant’s zone.
Capacity | Best For |
1.5 Ton | Small control rooms (<150 sq. ft) |
2 Ton | Medium processing areas (150-250 sq. ft) |
2.5 Ton | Large production halls (>250 sq. ft) |
✔ Calculate heat load from equipment, occupancy, and insulation.
✔ Consult an HVAC expert for precision sizing.
Flameproof enclosure (prevents internal sparks from escaping)
Corrosion-resistant housing (stainless steel or coated)
Sealed electrical wiring (no exposed connections)
Type | How It Works | Best For |
Ex d (Flameproof) | Contains explosions inside | Zone 1 high-risk areas |
Ex e (Increased Safety) | Prevents sparks | Zone 2 moderate risk |
Ex p (Pressurized) | Blocks gas entry | Labs, control rooms |
