  • Patent number: 10539381
    Abstract: An apparatus for cleaning HVAC cooling coils comprises a supply and collection assembly having a housing defining an interior space for containing a quantity of cleaning solution. A pump has a pump inlet positioned to be in fluid communication with the cleaning solution and is operative to deliver the cleaning solution to a supply outlet of the supply and collection assembly. A vacuum source has a vacuum inlet positioned to be in fluid communication with an ullage space above the quantity of cleaning solution such that the vacuum source creates negative pressure in the ullage space during operation. A collection inlet is in fluid communication with the ullage space such that the cleaning solution is returned to the interior space through the collection inlet during operation of the vacuum source. A nozzle device is in fluid communication with the supply outlet via outlet piping so as to deliver the cleaning solution to a surface of an HVAC coil unit.

  • Patent number: 10247494
    Abstract: A method for preventing fouling of an operating heat exchanger is disclosed. A carrier liquid is provided to the heat exchanger. The carrier liquid contains a potential fouling agent. The potential fouling agent is entrained in the carrier liquid, dissolved in the carrier liquid, or a combination thereof. The potential fouling agent fouls the heat exchanger by condensation, crystallization, solidification, desublimation, reaction, deposition, or combinations thereof. A gas-injection device is provided on the inlet of the heat exchanger. A non-reactive gas is injected into the carrier liquid through the gas-injection device. The non-reactive gas will not foul the heat exchanger surface and will not condense into the carrier liquid. The non-reactive gas creates a disturbance by increasing flow velocity and creating a shear discontinuity, thereby breaking up crystallization and nucleation sites on the surface of the heat exchanger. In this manner, fouling of the operating heat exchanger is prevented.

  • Patent number: 8652265
    Abstract: An improved method for cleaning heat exchange tube bundles, fin-fans, and other elongated components, using a portable cleaning system comprising a cleaning unit having a cleaning enclosure that receives and cleans the component and a control unit that controls the operation of the system. The cleaning unit has a cleaning enclosure defining a chamber sized and configured to receive the component through a sealable lid. A roller assembly rotates the component while a spray assembly sprays cleaning fluid over and into the rotating component. The cleaning fluid is heated in the chamber using surface heating elements attached to heat transfer plates along sections of the chamber walls. A vapor recovery system captures and treats toxic vapors. In use, the cleaning system is transported to a facility to clean the components on-site using cleaning fluid supplied by the facility and discharging waste to the facility.

    Abstract: An apparatus for cleaning a surface, such as the surface of a rotating disk, the apparatus comprising an articulating arm associated via a linkage to a rotating member driven by a motor. Rotation of the rotating member causes linkage to move the articulating arm in an oscillating pattern. A nozzle associated with the distal end of the articulating arm can convey pressurized air or liquid from a source to a surface in an oscillating pattern based on the construction of the arm, linkage, the rotating member and the speed of rotation.

  • Patent number: 8603336
    Abstract: A method for transferring heat includes flowing a wastewater through a tank and flowing a fluid through a heat exchanger having an outer surface. The method further includes aerating the wastewater to produce a convective flow, contacting the outer surface of the heat exchanger with the convective flow to exchange heat, and cleaning the outer surface of the heat exchanger with the convective flow. A system for transferring heat includes a tank, a heat exchanger with an outer surface disposed in the tank, and a fluid flowing through the heat exchanger. Wastewater located in the tank flows over the outer surface of the heat exchanger, and a diffusion pipe disposed in the tank provides air into the tank to produce a convective flow in the wastewater.
