Detandreny unit DPV2 UKE is designed for low temperature by expansion of compressed air. Each unit consists of the expander and a brake motor, mounted on a common base frame provided with a control flap that provides electrical power expander.
The design of the expander used DPA intake valve solenoid actuator, the principle of forward flow in production, oil-free piston seal, provides for protection of the expander "separation."
