Hazardous Environments
Facilities with flammable gases, vapors, or combustible dust require HVAC equipment that is specifically designed and certified for hazardous locations. Standard equipment is not just inefficient in these environments — it is prohibited by code.
What Hazardous Environments Facilities Face
Explosion Risk
Standard HVAC equipment can ignite flammable atmospheres, creating catastrophic explosion risk.
Code Compliance
NEC, ATEX, and IECEx standards require specifically certified equipment in classified locations.
Custom Requirements
Hazardous location HVAC often requires custom engineering for specific applications and environments.
Specialized Support
Specifying and installing hazardous location HVAC requires specialized expertise that most contractors lack.
