Design and Operation:

The scroll expander features a rotary scroll design that provides quiet, balanced, and pulse-free operation with a noise level of 50 dB(A).
It uses two identical involutes to form right- and left-hand components, creating crescent-shaped gas pockets for gas expansion.
The device operates with one fixed scroll and one moving scroll attached to an eccentric that drives a generator shaft.
The expander inlet is at the center, and gas expands as it moves toward the periphery, eliminating the need for valves and reducing noise.
Dynamic balancing allows for nearly vibration-free operation, and the absence of valves enhances reliability.

Performance:

Rated up to 1 kW with a maximum inlet pressure of 13.5 bar/200 psig.
Magnetic coupling prevents leakage, allowing use with various refrigerant gases.
Oil-free version operates at 70% efficiency, while the lubricated version operates at 80% efficiency.
