Isothermal compressors FAQs

An isothermal compressor works by compressing gas while maintaining a constant temperature throughout the entire compression process. This is achieved by continuously removing the heat generated during compression, typically through effective heat exchange systems such as water jackets, cooling coils, or external cooling mechanisms. Unlike adiabatic or polytropic compression, where temperature rises as pressure increases, an isothermal process ensures that the gas remains at the same temperature, resulting in greater energy efficiency. This is because less work is required to compress a gas when its temperature is kept constant. Isothermal compressors are commonly used in applications where energy efficiency is critical and the process allows for slow, controlled compression with effective heat dissipation.
Isothermal compression is a process in which a gas is compressed while maintaining a constant temperature. This minimizes energy losses and improves efficiency. Unlike adiabatic compression, which causes heat buildup, isothermal compression requires continuous cooling to maintain stability. 

Everllence isothermal compressors achieve this through integrated cooling systems, ensuring reliable, energy-efficient performance. By preventing excessive heat, they optimize gas density, enhance isothermal compression efficiency, and reduce mechanical strain. These compressors are ideal for air separation units and industrial gas processing, where large-scale air, oxygen, or nitrogen compression is essential.
