Quickly Dissipates Heat To Gain Efficiency In Your Production

Cooling natural gas has numerous benefits for equipment operations such as:

  • reducing the water content of the gas which reduces work on dehydrators
  • recovery of NGL’s which increases oil production

Our powered and non-powered Ambient Coolers are new or refurbished units with proven reliability at very competitive rates. Both systems are available for lease or sale.

Non-Powered Ambient Cooling Systems

Our non-powered Ambient Cooling Systems (ACS) passively cools the gas through a multi-pass, fin tube cooler section and can be equipped with optional after-cooling separation for condensed liquid removal. Cooler sections can be linked together to increase cooling effectiveness.


The Ambient Cooling System uses a roof to reflect the sun's rays and dispel heat from above. The open structure allows for prevailing winds to lower the temperature of hot gas that is entering the system so that a cool gas stream can flow out of the equipment.

Powered Ambient Cooling Systems

Our powered Ambient Cooling Systems (ACS) actively cool the gas using a motor-driven fan to force air through a fin tube cooler bundle. Our fans are either electrically powered or utilize a reliable, natural gas-powered engine.


  • Flexible leasing and rental contracts
  • No moving parts
  • No emissions
  • Safely and easily decreases temperature
  • Industry leading design and construction
  • Maximizes temperature drop
  • Increases dehydrator efficiency
  • Reduces enviroDRI usage when combined with a CROFT Passive Dehydration System


Forced Air Coolers



Utilizing Fresco Thermal's patent-pending cooling technology allows the Aeris Cooler line to have maximum modularity and fit most any natural gas cooling application.

Size Options

4x24 (most popular), 3x18, 2x12. The sizes are dependent on the number of cells x volume. Each individual cell and rack is rated for a volume of 6 MMScfd and can be added and subtracted from the package with ease. This level of modularity coupled with the state of the art cooling technology puts this gas cooler at the forefront of the oilfield technology.

  • On demand cooling
  • Programmable cells-auto/ manual option
  • Modular design
  • Transportation Friendly
  • Zero emissions
  • Monitoring option
  • Energy-Efficient
  • Pressure and temperature monitoring in/out of each cell.


The patent-pending design of the Aeris Cooling Systems creates maximum flexibility that allows up to four individual cells to be operated independently in either automatic or manual mode so that it can run in any combination of parallel, series, or separate process flows. Each cell is fitted with 2" NPT connections to allow for individual relief valves based upon conditions and preferences.



Aeris Cooling Systems are designed to fit into any standard shipping container and not be a permit load. This can save money on transportation costs. The standard size of the Aeris 4 X 24 is 7' tall, 20' long and 8' wide and weighs around 11,750 lbs. This can be lifted by crane or rolling tailboard, but there is an added option of using a roll-off truck for added precision and cost reduction.
