An air transfer apparatus being an integral or a monolithic structure or enclosure including an integral cavity and other cavities formed from a single piece of material. The integrated cavity includes a plurality of individual dividers forming a plurality of integral segmented cavities where pumps and motors are installed, and a controller which controls the operation of the pump motor such as turns on and off the pump motor and adjusts the speed of the pump motor. The air transfer apparatus is adapted to have at least one heat exchanger pad installed in at least of the sides of the walls and at least one fan installed in the air transfer apparatus.

A system for cleaning a tube is provided. The system includes an enclosure, a laser, and an actuator. The enclosure receives the tube. The laser is disposed within the enclosure and operative to ablate a substance disposed on a surface of the tube. The actuator is operative to move the tube relative to the laser.

A process for removing or reducing the accumulation of foulant within furnaces and heat exchangers in industrial systems such as an oil refinery by introducing a periodic steam blast. The steam blast is directed into the fluid stream from which the foulants form on to the heat exchanger surfaces. The steam blast increases the flow rates, creates turbulence and increases the temperature within the heat exchanger to dislodge foulant in both a soft and hardened states from internal surfaces upon which foulants have adhered and accumulated.

An apparatus for the maintenance and operation of an air-cooled heat exchanger (ACHE) includes a plurality of spray tubes provided with spaced-apart nozzles permanently positioned between the finned heat exchange tubes and longitudinally aligned within the region of the finned-tube pitch. The apparatus is operable in several modes, including cleaning where the flow of air is stopped and temperature-controlled pressurized water with an optional cleaning agent is discharged from the nozzles to dislodge dirt and debris from the finned surfaces while simultaneously cooling the hot process liquid. When extremes of ambient air temperatures preclude the forced air fans from achieving the target temperature range of the process liquid passing through the ACHE, refrigerated pressurized cooled water and compressed air in the form of a mist is discharged from the nozzles, or alternatively, pressurized heated air is discharged from the nozzles.

A method for cleaning a plurality of heat exchange surfaces; said method comprising: programming of an impulse wave cycle into a configurable controller in communication with a distribution network; transmitting an impulse wave through said distribution network to an outlet; measuring a plurality of pressures at a first location by a pressure sensor at said outlet; comparing at least one of said plurality of pressures from said measuring step with a programmed threshold pressure at said configurable controller; determining that one of said plurality of pressures corresponds to said programmed threshold pressure; completing impulse wave generation at said first location in accordance with said determining step; and moving said distribution network to a second location in response to said measured pressure corresponding to said threshold pressure.

A system for automatically washing and sterilizing a heat exchanger of a system air conditioner is proposed. The system for automatically washing and sterilizing a heat exchanger of a system air conditioner according to an embodiment includes: a washer body including an air compressor, a compressed air tank, a detergent liquid tank, a washing water tank, a washing water tank, a high-pressure pump, a hot air generator, a steam generator, and a hot air generator; a washing module that sprays washing water, etc., supplied from the ground during rotation thereof to a cooling fin by a spray nozzle, thus washing the cooling fin; a waste water collection vinyl cover that collects waste water dropping when the cooling fin is washed; and a controller configured to control the washing module that sprays washing water, etc., to the cooling fin.

Water-jet cleaning system and a method of cleaning a heat exchanger. The equipment includes a rotary tool having a lance with at least two degrees of freedom. The lance's movements relative to openings defined in the heat exchanger face plate are controlled via a smart indexing controller. The controller includes an electronic communication device that is specifically programmed to selectively activate various components of the rotary tool and a water delivery system. The programming utilizes an observed, learned, or uploaded pattern of the heat exchanger tube openings to selectively rotate the lance relative to the rotary tool's mounting assembly or linearly move the lance towards or away from the mounting assembly. The controller moves the lance to align a nozzle thereon with a selected opening in the face plate and then delivers a high pressure water jet therethrough.

One example provides a cooling system, including: a first side configured to face an ambient environment; a second side configured to face an enclosure interior; a flange that surrounds the system and is configured for attachment to an opening of the enclosure; a thermostat; one or more fans; one or more compressors; and a controller configured to: utilize two or more set points and input from the thermostat to variably control the one or more fans and one or more compressors using variable direct current (VDC).

A heat exchanger cleaning device is provided. The cleaning device includes a drive motor configured to rotate a gearbox, a slip clutch, and a support beam about a first axis. The support beam carries a thread rod, a second motor, and one or more carriage assemblies. The carriage assemblies move linearly as the second motor rotates the threaded rod. The carriage assemblies include a support tube for receiving an ultra-high pressure tube therethrough. The carriage assemblies adjust relative to the heat exchanger such that the UHP tube may be inserted through the support tube into a hole of the heat exchanger. Therein the UHP tube may be advanced to clean sediment from the heat exchanger tube.
