EGR Coolers cleaned using Ultrasonic Cleaning Equipment

Hydro-Zone has teamed with an Ultrasonic Equipment manufacturer for easy cleaning of multiple EGR Coolers. The Ultrasonic Equipment is designed and engineered for each customer to fit their needs. Now a mechanic can set 8 to 10 EGR Coolers in an Ultrasonic Cleaning Equipment Station and walk away and have the EGR Coolers cleaned in an hour. This new technology for cleaning EGR Coolers saves numerous hours a mechanic was using to setup the one cleaning pump through Cleaning Kit. Trucking Companies are benefitting greatly on saving the mechanics time. Now the mechanics can set in the Ultrasonic Cleaning Equipment System, walk away and work on other needs in the Service Centers. Trucking companies are cleaning their entire Truck Fleet in less than a week and incorporated the EGR Cooler Cleaning in a quarterly basis. Maintaining the EGR Cooler clean saves on Truck down time, fuel and emissions.

EGR Cooler Cleaner by Hydro-Zone, Inc. keeping trucks on the road

With this years long frigid winter, many truckers must leave their truck engines idling. Leaving the engine idling for hours causes the EGR Cooler to plug up with diesel particulates. The small tubes used in most Truck EGR Coolers become plugged quickly, causing the engine to stall or worse catch fire.

Hydro-Zone has the simple solution for cleaning the EGR Cooler. Hydro-Zone’s EGR Cooler Cleaner II is a Non-Hazardous cleaner that ships as a Non-Hazardous Material. With the cost of freight, safety and greener environment these days, Hydro-Zone’s research team developed a second edition EGR Cooler Cleaner called EGR Cooler Cleaner II. EGR Cooler Cleaner II is just as effective as the first edition, but ships as a Non-Hazardous Material. Neither EGR Cooler Cleaner I or II contain phosphates neither. Also, both EGR Cooler Cleaner I and II were both tested and approved at a Semi and Large Truck Manufacturer’s Technical Research Center. Both EGR Cooler Cleaner I and II were originally formulated for the large Truck Manufacturer. Seeing how successful the Cleaners perform, Hydro-Zone decided to open up the sale to other Truck Manufacturers and Truck Service Centers.

Hydro-Zone also sells the EGR Cooler connections, seals, pump, pail, hoses, clamps and flanges as a Cleaning Kit or as individual parts, when needed.

Call us today and order our EGR Cooler Cleaner II. EGR Cooler Cleaner comes packaged in one-gallon, 4×1 gallon case, pallet of 4×1 cases, 5-gallon pail, 15-gallon keg, 30-gallon and 55-gallon drum and 275-gallon one-way totes.

EGR Cooler Cleaner by Hydro-Zone cleans and restores completely plugged EGR Coolers in less than an hour

Hi All Our Truck Friends:

Hydro-Zone’s EGR Cooler Cleaner cleans and restores completely plugged EGR Coolers in less than an hour. The EGR Cooler is plugged with diesel soot and particulates and this blocks the Diesel Engine from expelling exhaust, shutting down the Engine. Soaking the EGR Cooler in Hydro-Zone’s EGR Cooler Cleaner will completely clean the EGR Cooler of all soot and particulates. Just add one gallon of EGR Cooler Cleaner to two gallons of hot water and soak. If possible, hookup a garden hose to a small sump pump and attach to the EGR Cooler. Hookup another garden hose from the EGR Cooler and hang into a 5-gallon pail. Insert the sump pump into the 5-gallon pail and turn on the sump pump. Recirculate the EGR Cooler Cleaner/ hot water solution for an hour through the EGR Cooler and back to the 5-gallon pail. Now your EGR Cooler is completely clean and like new. After cleaning the EGR Cooler, flush the EGR Cooler with fresh water. Add 3 gallons fresh water to an empty 5-gallon pail and flush EGR Cooler for 10 to 15 minutes with same hose and sump pump used to clean. Then use compressed air and blow air through the EGR Cooler for 5 to 10 minutes to completely dry. Now you are ready to hookup your EGR Cooler back onto your Engine and you will be ready to drive again.
