Cleaning system having heated cleaning enclosure for cleaning heat exchanger tube bundles

A system for cleaning one or more elongated components, comprising:

• a cleaning unit having a cleaning enclosure with a bottom wall, a pair of opposing upstanding sidewalls, a pair of opposing upstanding end walls and a lid pivotally attached to one of said sidewalls, said cleaning enclosure defining a chamber sized and configured to receive the one or more elongated components and a cleaning fluid therein;
• a sealing means interconnecting said sidewalls and said end walls for sealably closing said lid against said sidewalls and said end walls to prevent the release of fluids and vapors from said chamber while cleaning the one or more elongated components with said cleaning fluid;
• one or more roller assemblies positioned inside said cleaning enclosure so as to rotate the one or more elongated components in said chamber, each of said roller assemblies having at least one drive roller;
• a spray assembly disposed inside said chamber for spraying said cleaning fluid over the length of the one or more elongated components, said spray assembly comprising a plurality of spray nozzles directed generally inward from at least one of said sidewalls and/or said end walls;
• a pump system in fluid flow communication with said chamber so as to draw said cleaning fluid from said chamber, pressurize said cleaning fluid and direct said cleaning fluid to said spray assembly;
• a heating system having a plurality of fluid heating assemblies at each of said sidewalls, each of said fluid heating assemblies having a heating element disposed against a heat transfer plate in a heater cavity at a wall section of said sidewalls in thermal conductive contact with said cleaning fluid when said cleaning fluid is in said chamber, said heater cavity defined between said heat transfer plate and a cover plate, said heat transfer plate selected so as to transfer heat from said heating element to said treating fluid in said chamber;
• a vapor recovery system configured to draw vapors from said chamber and filter said vapors prior to venting gases from said cleaning enclosure;
• and
• a control unit having a control panel configured to operatively control the movement of said lid between an open position and a closed position thereof, the rotation of said one or more roller assemblies, the operation of said pump system, the energization of said heating assemblies and the operation of said vapor recovery system;
• wherein said control unit has a control enclosure enclosing said control panel and one or more control consoles in an interior space of said control enclosure and a forced air cooling system that is in air flow communication with said control enclosure so as to place positive pressure in said interior space of said control enclosure to prevent entry of potentially explosive fumes therein.
