Category: Atex Air Conditionning, Explosion Proof Products
Keeping people and equipment safe in hot, hazardous environments isn’t optional—it’s essential. The ATEX Air Conditioner delivers reliable cooling (and optional heating) for areas where flammable gas or combustible dust may be present. It uses explosion-protected components, controlled surface temperatures, and rugged enclosures so you can stabilize temperature and humidity without adding risk. In simple words: cool, safe, and built to last.
What is ATEX Air Conditioner
An ATEX Air Conditioner is a climate-control system designed for ATEX-classified zones. It’s engineered to prevent sparks or hot surfaces from becoming an ignition source. Unlike standard ACs, it features certified electrical parts, sealed control panels, Ex-rated cable glands, strict temperature-class control, and markings that match your zone and gas/dust group. You can use it in Zone 1/2 (gas) and Zone21/22 (dust) locations when the correct model and certification are selected. It’s a proven way to protect people, electronics, and processes in oil & gas, chemicals, batteries, marine, food, and more.
Key uses of ATEX Air Conditioner
Protects people: Keeps workspaces comfortable so teams stay alert and productive.
Protects electronics: Stabilizes temperature in analyzer shelters, MCC rooms, and PLC cabinets.
Reduces risk: Ex designs limit ignition sources in classified areas.
Improves quality: Consistent climate supports paint mixing, batching, and precision work.
Boosts uptime: Rugged parts, better filtration, and smart alarms cut unplanned stops.
Key applications

FAQs
1) Which zones does this unit cover?
Models are available for Zone 1/2 (gas) and Zone 21/22 (dust). We match the Ex marking to your dossier.
2) How do I choose the right temperature class (T-class)?
T-class limits surface temperature. It’s set by your gas/dust properties and risk study. T4 is common; we’ll confirm during selection.
3) Can it connect to our BMS/DCS?
Yes. You can monitor alarms and status via dry contacts or Modbus RTU (with certified barriers where needed).
4) What about refrigerant safety?
We select A1-class (non-flammable) refrigerants such as R134a, R407C, or R410A, aligned with your risk assessment and local rules.
5) Do I need stainless steel outdoors or offshore?
For marine or corrosive sites, 304/316L housings and coated coils (C5) extend service life.
6) How is maintenance different from a normal AC?
Intervals are similar, but procedures follow Ex rules. Use certified parts and keep records for audits.
7) Can you supply packaged or split systems?
Yes—split, ducted, rooftop, and precision variants are available so we can fit the space and duty.
