HVAC in Oil and Gas Industry

Premium ventilation and air handling systems engineered specifically for the demanding environments of oil, gas, and petroleum facilities. Our solutions deliver uncompromising reliability in high-stakes industrial settings where standard HVAC systems fall short.

Why Specialized HVAC Matters in Oil & Gas

Oil and gas facilities operate in some of the most demanding industrial environments on earth. Standard ventilation systems simply cannot handle the extreme conditions these facilities face daily, from corrosive atmospheres to volatile compounds.

Key challenges we address:

  • Extreme heat and corrosive materials requiring specialized equipment
  • Hazardous fumes demanding precise air handling systems
  • Critical safety compliance for high-risk environments

HVAC Design for Oil and Gas Facilities

These are just a few ventilation equipment that are provided, as well as an array of other fans to meet the criteria to move air required by the gas and oil industry.

There are generally 5 types of main oil and gas facilities that have a unique production process. Each oil & gas facility requires a unique HVAC equipment.

Exploration Facilities

Drilling ventures where crude oil, petroleum and gas is searched for and extracted.

Upstream Facilities

Handle the production of the oil. Upstream facilities also are responsible for stabilizing the gas products.

Midstream Facilities

Liquified natural gas (LNG) production, gas, petroleum and oil are treated in midstream facilities. They are then run through a pipeline network system.

Refining Facility

Processing oil and its condensates into products that are marketed. Within the oil refinery there are 5 major processes:

Each of their processes produce a product such as diesel, feedstock, gasoline and other gases for the petrochemical industry.

Ventilating Oil Exploration & Extraction Facilities

The various facilities for gas and oil, especially American shale, has forced regulators to implement tougher emission standards. In order to remain compliant, proper ventilation equipment, is paramount.

Combustible dust and volatile flammable liquids need to be properly controlled. As a result, ducting and industrial grade air filters are required that meet OSHA requirements.

Air pollution control to protect not only the site, process and employees, but also the people it serves and the surrounding community.

Oil and Gas Upstream Facilities Ventilation Systems

A common issue with upstream facilities, due to the environment of producing the oil and stabilizing the gas products, is poor indoor air quality issues. Upstream production facilities can be difficult environments for employees due to poor ventilation.

Again, due to tightening compliance in the US, it’s important to provide a safe environment for oil facility’s staff. Therefore, an air filtration system of the highest quality is required.

Petrochemical Plant Exhaust Fan

Exhaust fans are necessary in all stages of oil and gas processing. Whether it’s cooling spark resistant fans or keeping employees cool, exhaust fans with sensors are available to reduce machine downtime. When dealing with volatile flammable liquids and gas, explosion rated fans are essential.

Make-up Air Units for Oil Facilities

Upstream facilities also are responsible for stabilizing the gas products. Industrial make-up air units for oil facilities is another option that can accomplish this. Make-up air units play a vital role in properly maintaining pressure inside upstream oil production facilities.

Corrosive Duty Fans for Midstream Facilities

Although there has been negative feedback, crude oil, petroleum and liquified natural gas (LNG) pipelines are consistently being approved and prior facilities require proper ventilation.

Midstream facilities implement variable frequency drive shelters (VFDs) and remote instrument enclosures. Variable frequency drives produce large amounts of heat that must be dispelled according to proper compliance code.

Failure to dissipate the immense amount of heat causes the midstream equipment to fail. Therefore, cooling and exhausting heat for these high sensible load applications is vital (source).

Ventilation equipment to reduce noise in VFD’s

Another factor to consider with VFD is noise control. Acoustic building systems are a solution to reduce noise generated from the gas and oil equipment.
There are several common factors that increase the noise level in VFD’s. To combat the noise there is ventilation equipment to reduce the decibel level to meet standards.

Oil Refinery Ventilation Systems

Oil refineries from the outside look like a small city. A city made up of tanks, pipes, building structures and towers.

Oil refineries process and refine crude oil into fuels, gas, lubricants and other high grade oil products. The refined oil and gas products are provided to consumers.

Heat removal and ventilation equipment of oil refineries must adhere to the American Petroleum Institutes (API) and Occupational Safety and Health Administration (OSHA) standards using temperature controlling equipment that adheres to their regulations.

Air filtration systems are implemented throughout the refinery. All industrial fans, blowers, make-up air units are explosion resistant that meet National Electrical Code (NEC) that is suitable for oil and gas systems.

Corrosive Duty Fans and Blowers

Due to the high temperatures and corrosive atmospheres where blowers and fans are required to exhaust gases; corrosive fans and blowers are compulsory.

The materials used to construct the fan, as well as the fan design, must be carefully considered to achieve optimal performance while also being extremely durable.

Gas and oil generate corrosive byproducts and condensates that must be exhausted. These corrosives introduced to the environments must be taken into account when selecting materials and design of heavy duty industrial fans and blowers in order to maximize performance.

Oil and Gas Electrical Equipment for Class 1, Div. 1

All electrical equipment, such as ventilation equipment, is required to meet class 1 div 1 guidelines. Such equipment is necessary in areas where explosives, gases and asphyxiation is possible. Class 1 Div 1 exhaust fans are required most oil facilities.

Explosion rated controls, fans, and components suitable for a Class 1 Division 1 are required and applied accordingly.

The equipment needed must check all of the boxes, suitable for heavy duty applications such as oil and gas, explosive duty, corrosive duty and moisture laden applications that create condensates.

Any company that operates work sites that include hazardous materials require products that are certified to ensure staff safety.

Certified Exhaust Fans for the Oil Industry

Only testing from an accredited laboratory can certify ventilation equipment. The Occupational Safety and Health Administration (OSHA) recognizes qualified firms, such as a Nationally Recognized Testing Laboratory (NRTL).

The NRTL is able to evaluate hazardous location equipment and certifies them when they meet ventilation requirements.When electrical equipment passes the specification and design requirements that are critical for safety they are then certified. A few of the main assessment parameters include:
