Blade Compressors for Refrigerants
Although, up to now, Lontra has concentrated on air compressors, the underlying technology is very similar to that in refrigeration compressors and similar gains in efficiency and reliability are expected using the Blade Compressor technology to compress modern refrigerants such as R32.
Getting Ready for the Air Conditioning and Refrigeration Industry

Lontra’s Blade Compressor is a positive displacement design, already competing with reciprocating, scroll and screw type compressors in other markets, but unlike any of them.
It is best imagined as a piston and cylinder “wrapped around”, where the single piston or “blade” continuously rotates, simultaneously inducing refrigerant behind and compressing refrigerant against a rotating disc in front.
There is a BBC video on YouTube that explains the principle much more clearly:
With efficiency a key driver for many in the ACR industry and with the challenges around new low GWP refrigerants, we think that Lontra and its Blade Compressor is definitely “one to watch”
