Configuration Options
Choose the ATEX configuration that matches your facility's hazardous area classification:
1 Indoor Unit for ATEX Zone 2 + Outdoor Unit for Safe Area
Most Cost-Effective Option
ATEX-certified indoor unit operates safely inside your hazardous classified space while the standard outdoor unit is installed in a non-classified zone. Ideal for control rooms, operator shelters, and indoor storage areas.
2 Indoor Unit for Safe Area + Outdoor Unit for ATEX Zone 2
For Outdoor Hazardous Zones
Standard indoor unit in safe space with ATEX-certified outdoor unit in classified outdoor area. Common for offshore platforms and facilities where outdoor areas are hazardous but indoor spaces are not.
3 Both Indoor and Outdoor Units for ATEX Zone 2
Complete Explosion-Proof System
Both units ATEX-certified when both indoor and outdoor locations fall within classified zones. Maximum flexibility for fully classified facilities.
