E14H027A-SH-CI Semi-Hermetic Cast Iron Scroll Expander

With durable cast iron construction, the E14H027A-SH-CI can be used with many different working fluids, and at pressures and temperatures higher than most expanders. It has a maximum inlet pressure of 25 bara and a maximum inlet temperature of 200 ºC.

Designed for waste heat recovery on a semi-truck, the expander is very robust. The unit was designed for 3,600 RPM, offering a compact design for space-constrained applications. The expander utilizes Air Squared’s patented magnetic coupling design and features oil injection access for lubricated operation.
