Misting fan system and method

A misting fan system for use on oil and gas rigs comprising:

• a hydraulic fan motor for generating a rotational force from a hydraulic fluid, the hydraulic fan motor being contained within a cover that is affixed to a mounting block, the mounting block being affixed to a mounting block support that traverses a shroud;
• a water pump member for pumping water;
• a control member, the control member controlling the flow of the hydraulic fluid and the water;
• a fan device positioned within the shroud, the fan device having a plurality of blades for providing an airflow, the fan device being operatively connected to the hydraulic fan motor;
• one or more nozzles each fluidly connected to the water pump member for spraying a mist, the one or more nozzles each containing a variable opening for varying the volume of water discharged from the nozzle;
• a drip pan positioned below the fan device, the drip pan providing a fluid leak containment area;
• wherein the mounting block support includes an internal fluid leak path in fluid communication with the mounting block through which hydraulic fluid leaked from the hydraulic motor flows for containment in the fluid leak containment area of the drip pan.
