A method of using such a system is also provided. | 02-23-2012 |
20120292240 | COMBINATION FILTER ARRANGMENT AND METHOD - A cartridge type filter is mounted in a housing and is serviced through the top of the housing. The cartridge includes first and second media packs axially stacked. The second media pack is in series behind the first media pack, and filters a portion of the liquid therethrough. The second media pack has a higher efficiency than the first media pack. The overall design has a drain system which allows liquid to drain from the interior of the filter housing and back to the sump before the filter cartridge is completely removed from the housing. Other optional features include an oil cooler, various valving, and a filter cartridge lockout mechanism. | 11-22-2012 |
20130193049 | MULTI-STAGE CENTRAL MIX AND MAKE UP SYSTEM FOR SUPPLYING ANY PLURALITY OF METAL WORKING MACHINE COOLANT FILTRATION SYSTEMS - A system for producing and supplying a coolant to a filtration sub-system, and for reconditioning and recombining a return flow of used coolant. A main reservoir is in two way communication with the filtration sub-system via a clean coolant outlet and a dirty coolant return. An inlet feeds an untreated water supply to a de-ionization canister. A mixing valve in communication with the inlet recombines a remaining untreated portion of the water supply with the de-ionized portion. A mixing pump intermixes the water supply with a chemical concentrate to produce a coolant delivered to a main reservoir. A volume of coolant is drawn through an outlet from the reservoir and communicates the coolant to a particle filter, a chiller, and prior to outputting to the filtration sub-systems. The used return coolant is filtered and reintroduced to the main reservoir. | 08-01-2013 |
20130199979 | FLUID FILTER - A fluid filter may include a filter housing including a pot and a lid. A ring filter element may be arranged within the filter housing, through which flow may pass radially and which separates an untreated space from a clean space. The ring filter element may have an upper and a lower end disc. A heating device may be configured to allow heating of the fluid to be filtered. The filter housing may define a port into which the heating device is inserted and the port may separate the heating device from the fluid to be heated. | 08-08-2013 |
20130213870 | COOLING TOWER BLOW-DOWN, GROUNDWATER AND WASTEWATER RE-USE PROCESS AND SYSTEM - A cooling tower blow-down, groundwater and wastewater re-use process and system is provided, which system may further include a cooling tower evaporation recovery system and process. Thus, blow-down from cooling equipment may be reused by appropriate treatment of the blow-down water, or treatment of other sources of water such as groundwater or wastewater, for use as make-up water in a cooling tower or other cooling equipment, and the capture of evaporation from cooling equipment is conducted to increase the efficiency and lower costs in the operation of such equipment. | 08-22-2013 |
