ABSTRACT:
An apparatus and process for cooling and muffling one or more pieces of exhaust emitting industrial equipment, such as a pair of vacuum pumps, is herein disclosed. The apparatus comprises a water cooling tank, an automatic water level control means for automatically maintaining the water in the tank to between a predetermined maximum and minimum level, and a thermostatically controlled refrigeration coil concentrically disposed within the tank for maintaining the temperature of the tank water to between a pre-selected range. The tank includes one or more muffling units substantially submerged in the water within the tank and pneumatically connected to the exhaust ports of the industrial equipment for muffling the exhaust noise of the equipment. The gases expelled from the industrial equipment pass through a plurality of small apertures in the submerged portions of the muffler units and create a plurality of small bubbles which effectively agitate the tank water around the refrigeration coil, thereby equilibrating the temperature of the water and eliminating the need for a separate agitation pump.
