Everest Sciences

Everest Sciences

Everest Sciences was founded in 2008 in Tulsa, Oklahoma. We developed the first-of-its-kind inlet cooling process known as the Everest Cycle, a patented hybrid indirect evaporative–chilling cycle. This process is fundamentally more efficient than traditional cooling methods. It provides cooler, denser air with fewer parasitics than any competing system. We have achieved success in the oil and gas industry and the chemical processing industry. With installations at leading interstate pipelines, midstream pipelines, processing plants and syngas plants in the United States and overseas, Everest Sciences has a proven record of helping you increase your flow and revenue. We try to partner with international organisations but it’s not quite our focus yet.

Year Founded:

The company has both improved and commercialized this process to create a line of modular cooling solutions that provide consistent operating conditions all year round. The Everest Sciences ECOCool™ and ECOChill™ systems utilize the Everest Cycle to provide consistent cool, dry air for our customer applications. Recent applications have given midstream natural gas operators the ability to meet contractual requirements for gas processing and transmission, and allowed ammonia producers to increase output at in a timely manner. Everest Sciences has achieved significant market acceptance of its products, with installations or contracts to install throughout North America, Mexico and the Caribbean in leading natural gas gathering, separation and fractionation facilities and chemical manufacturing installations.

Everest Sciences is a private held company headquartered in Tulsa, Oklahoma. Tulsa is home to many world class manufacturing companies and boasts some of the top experts in field of heat exchangers.

Proprietary Everest Sciences™ technology can increase gas turbine hot day available power by up to 30%, while reducing heat rate by up to 10% compared to un-cooled gas turbines. With today's power requirements, rising fuel costs, and increased awareness of emissions, the Everest Sciences solution has clear benefits for gas turbine users.

Unlike conventional solutions, Everest Sciences indirect evaporative cooling does not introduce evaporated water into the gas turbine's primary airflow. Instead, evaporation occurs in a secondary air stream, which in turn cools the primary air without the density reduction associated with increased moisture content. The Everest Cycle™ achieves equivalent cooling to refrigeration using substantially less power, in a compact modularized system.

Turbine Inlet Cooling Historical Solutions

Direct Evaporative Cooling

  • Direct Evaporative Cooling works by allowing inlet air to pass through wetted media.
  • In this process, moisture evaporates and cools in the inlet air.
  • Consequently, the direct evaporative process introduces moisture into the inlet air.
  • The moisture limits the density reduction of the inlet air, reducing mass flow into the gas turbine, reducing overall output.


  • Fogging cools air by injecting a fine mist of de-ionized water into the inlet air stream.
  • Evaporation of the water cools the inlet air temperature.
  • Similar in concept to direct evaporative cooling, fogging introduces moisture limiting the density reduction of the inlet air, reducing mass flow into the gas turbine, reducing its overall output.
  • Fogging can introduce non-evaporated water droplets into the turbine inlet, with the potential to damage the compressor.
  • Special de-ionized water treatment is required in fogging systems to prevent mineral carryover.
  • It is well known that de-ionized water is aggressive on equipment.
  • Compressor degradation and failure associated with over-fogging can limit its application with many combustion turbine manufacturers.


  • Refrigeration achieves greater inlet air cooling than direct evaporative and fogging techniques.
  • Refrigeration cools without introducing moisture into the air stream, allowing for denser inlet air.
  • However, it requires high power off-takes, or parasitic loads, that lead to higher overall heat rates.
  • Direct refrigeration is a complex system that needs cooling towers, multiple pumps and piping, constant water conditioning, and often results in higher maintenance costs.
  • A cooling coil required for direct refrigeration systems results in higher pressure drops.

The Everest Sciences solution brings a proprietary combination of indirect evaporative cooling combined with our h3 technology.

Indirect Evaporative Cooling

  • Water evaporative cooling in a secondary air stream that does not enter into the turbine
  • Technique does will not add moisture to primary turbine inlet air stream

Everest Sciences h3 Technology

  • Introduction of small amounts of refrigeration in order to further cool our Everest Cycle
  • Chilled indirect evaporative technology brings the refrigerated inlet air to the gas turbine resulting in lower heat rates

Over the years Everest Sciences has explored the best ways to create solutions without the side effects associated with traditional inlet cooling approaches. We have assembled a team of industry experts focused on delivering superior product performance and outstanding customer service. Our patented proprietary Everest Cycle is the most efficient answer to turbine inlet cooling.
