high efficient concentrators working principle

  • Oxygen Concentrator

    The oxygen delivery systems available for home use are as follows: compressed gas in high-pressure cylinders; liquid gas in lightweight canisters; and stationary oxygen concentrators. Large compressed gas cylinders are fixed in place, but patients can move short distances while using long (50-ft) tubing; smaller cylinders can be attached to wheelchairs or installed in automobiles to allow journeys out of the home.

  • Concentrating Solar Power (CSP) Technology

    CSP plants generate electric power by using mirrors to concentrate (focus) the sun's energy and convert it into high-temperature heat. That heat is then channeled through a conventional generator. The plants consist of two parts: one that collects solar energy and converts it to heat, and another that converts the heat energy to electricity.
