At the heart of the HotStack 300 is the IsoStack compressor
At the heart of the HotStack 300 is the IsoStack compressor
Isothermal compression cycle creates ultra-high efficiency
Single stage compression for the full 110˚C temperature lift lowers capex cost
10-to-100% turndown capacity that flexes to your manufacturing schedule
Infinitely variable compression ratios that enable flexibility on temperature lift both pre and post installation
Modular, stackable system adjustable for small to large scale processes
