1. A system for lubricating a target located within a refrigerated atmosphere, said system comprising:

  • a lubricant source;

    a pressurized air source;

    a pressure regulator;

    a pump in communication with said lubricant source;

    a spray nozzle, said spray nozzle connected to said pump by a lubricant supply line, said spray nozzle connected to said pressure regulator by an air supply line;

    a first solenoid for controlling said pump and a second solenoid for controlling an airburst released at said spray nozzle, said first solenoid being connected to said pump and said second solenoid being connected between said pressure regulator and said spray nozzle;

    said pressure regulator being adjustable to provide said airburst at a predetermined intensity;

    a programmable logic controller, said programmable logic controller being connected to said first and second solenoids;

    a sensor for sensing the target to be lubricated;

    whereby said sensor sends a signal to the programmable logic controller which signals the first and second solenoids to each open independently at a predetermined time for a predetermined duration;

    temperature regulating means for regulating the temperature of said air supply line wherein said temperature regulating means comprises a heating element positioned proximate to and extending longitudinally adjacent to said air supply line;

    whereby condensation caused by said refrigerated atmosphere is substantially prevented from forming in said air supply line; and

    whereby said pump, said pressure regulator, said first and second solenoids, and said programmable logic controller are located outside said refrigerated atmosphere.
