A compressor is a mechanical device that increases the pressure of a gas by reducing its volume, and is widely used across industrial, commercial, and portable applications.
Efficient thermal management is critical to compressor performance — during operation, compressors generate significant heat that must be dissipated to prevent overheating, reduce wear, and extend equipment life. This includes air cooling to manage discharge temperatures, oil cooling to maintain lubrication integrity under load, and air drying to remove moisture from compressed air streams, which is essential for protecting downstream equipment and ensuring air quality.
General ThermoDynamics & Airtech offers a comprehensive range of high-performance thermal solutions designed to meet these demands for both portable and stationary compressors. Whether you require aftercoolers, oil coolers, or combination units, we have the expertise and product lineup to deliver reliable, application-matched solutions that keep your compressor running at peak efficiency.
Industry-leading innovation.
Our Airtech FinSep® Aftercoolers utilize a unique design that combines cooling and moisture-separating technologies into one comprehensive unit. They deliver proven performance in compressor packages worldwide.
Our shell and tube heat exchangers and our plate heat exchangers have been tirelessly engineered to provide optimal cooling for liquid cooled applications.
The applications we serve include portable, stationary and oil-free compressors:
Reciprocating (Piston) Compressor – Uses a piston driven by a crankshaft to compress gas within a cylinder.
Rotary Screw Compressor – Employs two meshing helical screws to compress air continuously.
Centrifugal Compressor – Uses a high-speed rotating impeller to accelerate and then decelerate gas, converting velocity into pressure.
Rotary Vane Compressor – Relies on a slotted rotor with sliding vanes that create variable-volume chambers to compress air.
Scroll Compressor – Uses two interleaved spiral-shaped scrolls to trap and compress gas.
Diaphragm Compressor – Compresses gas using a flexible diaphragm rather than a piston.
Turbo Compressor – A type of dynamic compressor that uses high-speed rotating components to transfer kinetic energy to the gas.
Oil-Free Compressor – A design variant (applied across multiple compressor types) that eliminates oil from the compression chamber, critical for applications requiring clean, uncontaminated air such as food, medical, and electronics industries.
Portable Air Compressor – A compact, mobile compressor unit typically based on reciprocating or rotary screw technology, used on job sites and in applications where a fixed compressed air supply is not available.
