A cleaning apparatus for cleaning a cooling tube array (15) of a heat exchanger has a nozzle carriage (16) movably held on a truss beam, and a plurality of cleaning nozzles (40) mounted to the nozzle carriage. A truss beam has two parallel C-channel rails (20) having back sides that face each other, a tube (22) arranged separate and distant from the C-channel rails and at a different height than the C-channel rails in a cross-sectional plane of the truss beam, and truss supports (24) connecting the rails and the tube; the nozzle carriage has rollers (48) that are arranged for travelling in the C-channel rails. A water intake (82) is coupled to the nozzle manifold (42) and to a hydraulic drive (80) having a mechanical power take-off member (96) that is operably coupled to the nozzle carriage (16) for moving the nozzle carriage.

A frame-mounted mobile cleaning system permanently positionable above or below the tube bundles of an air-cooled heat exchanger (ACHE) and in fluid communication with an external source of pressurized cleaning fluid includes a mobile transverse spray head assembly formed from a plurality of separate interchangeable fluid compartments, each fluid compartment having an inlet for receiving the pressurized cleaning fluid and a fluid discharge wall having at least one, and preferably a plurality of spaced-apart individual spray nozzles that are aligned with the longitudinal axes of the finned heat exchange tubes below or above, or elongated slot nozzles that are transverse to the axes of the finned tubes and that are configured to discharge a predetermined pattern, e.g., an elongated pattern of pressurized cleaning fluid onto and between the surfaces of the fins of the heat exchange tubes as the assembly is moved from one end of the ACHE tube bundles to the other. The system is advantageously securely mounted on a support frame that is, in turn, mounted on a transport mechanism that includes wheels that move on retaining tracks secured to the side walls of the ACHE housing, where the tracks extend to a storage position that is displaced from the open air circulation region above the tube bundles when the cleaning operation has been completed.

A cooling device for reducing the temperature of cooked warm food in a liquid or paste-like state held in a container, in particular in a standard trolley, is provided. The cooling device includes a plate-like covering member which covers the opening cross-section of the container or of the standard trolley, wherein the covering member has vertically arranged cooling elements on the lower face thereof, which cooling elements, when the cooling device is attached and lowered, are immersed in the density of the food and a cooling medium circulates through the cooling elements, which cooling medium extracts the stored heat from the food.
