CO2 laser recirculation compressors and coolers

[rppearso]

Does anyone know what the best recirculation compressors are for a high power CO2 laser. I would like a small foot print low flow positive displacement compressor (rotary vane or diaphragm maybe?) that is not an expensive noisy monstrosity for maybe a $100 or so. Also does anyone know of a good cooler unit that takes regular automotive refrigerant or other commonly available refrigerants that is also small and low profile also that is not terribly expensive.

I have been finding through reading that it will be impossible to achieve a 20 Kw or higher IR laser without recirculation.

Thank you,
Ron

For recirculating compressors, I would recommend the rotary vane compressor. It is a reliable and cost effective option for powering a high power CO2 laser. These compressors are typically small in size and can be mounted on to a wall or ceiling. As far as coolers are concerned, you might consider an air cooled unit that uses a condenser and evaporator to cool the CO2. These units are generally low profile and can be mounted on a wall or ceiling. They use a refrigerant such as R134a, which is commonly available.
