Water cooled Isolated SCR Modules

ISOLATED SCR MODULES Integral Water Cooled

Darrah offers Isolated SCR Modules featuring standard dual SCR modules witg integral water cooled bases. Our improved design has eliminated thermal barriers associated with separate cooling bases. This product line features industry standard dual SCR modules with integral water cooled bases. Our improved design has eliminated thermal barriers associated with separate cooling bases. This has increased current ratings by as much as 15%. In addition, because the water connections are directly tapped to the module base, water leaks are virtually eliminated. To further enhance water integrity, each unit is 100% pressure tested at 150 PSI for one minute.
Another significant feature is that the modules are vacuum filled with a high performance, flame retardant silicone-based material at final assembly which eliminates hidden voids inside the package and prevents dust and dirt from penetrating which may cause premature failure. All cooling bases are copper, then nickel plated.
Our modules are recognized under the Recognized
Component Program of Underwriters Laboratories, Inc. USA.
