Abstract

A condensate removal system is provided for use in association or connection with equipment that produces a liquid or condensate during operation. The condensate removal system is configured to receive a liquid or condensate produced by equipment and is configured to induce the liquid or condensate to flow from the system as liquid or condensate droplets and/or liquid or condensate vapor. The system is configured to contain and to vibrate a liquid or condensate received from equipment in an ultrasonic frequency zone to induce the liquid or condensate to form into droplets and/or vapors. The system is configured and arranged to force the droplets and vapors from the system and can be further configured to expel the droplets and vapors to an area external to the system and/or into a duct, for instance, to exhaust the droplets and vapors or to recirculate the droplets and vapor to equipment to provide cooling to the equipment and/or components of the equipment.
