Solutions for Cooling Natural Gas
Why Cool Natural Gas?
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 cool 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.
How It Works
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.
Forced Air Coolers
Utilizing Fresco Thermal's patent-pending cooling technology allows the Aeris Cooler line to have maximum modularity and fit most natural gas cooling applications.
Technology
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 on conditions and preferences.

Mobility
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.
