Explosion-Proof HVAC

Oil & Drilling ApplicationEnvironmental control applications involving or exposed to combustible substances demand the use of specialized equipment to ensure operator safety and prevent explosions. For these scenarios, explosion-proof HVAC systems serve as an ideal solution. These systems find use in a wide range of industries, including aerospace, military, oil and gas, and pharmaceutical manufacturing.

At Air Innovations, we design and manufacture custom explosion-proof HVAC systems that provide full temperature and humidity control. Our solutions are suitable for use in volatile ambient conditions and meet Class I, Division I and Class I, Division II standards.

 

What Are Explosion-Proof HVAC Systems?

The National Electrical Code (NEC), produced by the National Fire Protection Association (NFPA) since 1897, provides the working definition for several equipment classifications, including explosion-proof. For equipment—including HVAC systems—to receive this rating, they must be able to contain any explosions that originate within their enclosure, effectively preventing them from causing a larger explosion.

Additional criteria include

• Meeting the temperature requirements of the operating environment (regarding combustible substances)
• Completing testing that verifies they meet all other requirements (with the verified classification indicated on the nameplate)

 

Our Explosion-Proof HVAC Solutions

The vast majority of companies—about 90%—that produce explosion-proof HVAC systems focus their efforts on standard, off-the-shelf products. At Air Innovations, we cater to the other 10%.

We design and manufacture custom systems for customers with unique needs that are not met by standard products. If a customer can’t find an adequate solution off-the-shelf, we have the experience and equipment necessary to provide them with an ideal HVAC system solution.

Our custom explosion-proof HVAC systems are designed to meet precise performance and packaging specifications, which include

• Temperature control: from -18° C to 38° C with tolerances as precise as +/- 0.02° C
• Humidity and dew point control: from 0.1% RH to 95% RH with control tolerances to +/- 0.5%
Filtration: HEPA, ULPA, molecular

Air Innovations explosion-proof HVAC systems can be designed to regulate temperature to tolerances as tight as ±0.02°C and humidity to 0.1% RH from very low humidity levels to 95%RH. Additionally, our conditioning systems can provide filtration HEPA, ULPA, molecular levels and more. View our full environmental control capabilities.

 

Benefits of a Custom HVAC System From Air Innovations

While standard, off-the-shelf solutions can often meet most HVAC system needs, there are several advantages of investing in one of our custom solutions. These include

• More innovative concept design and development
• Multi-disciplined engineering team approach
• Better quality guaranteed through prototyping and testing
• Greater flexibility in production quantities (from small to large runs)
• Regulatory submissions to proper authorities
• Broader warranty and serving support
• Capacity for global distribution
