Hydrostatic Release Kit
Product No.: 9490
Model No.: HRU-100
ACR Electronics, the world leader in safety and survival technology since 1956, proudly introduces the HydroFix™ Hydrostatic Release Unit (HRU) to compliment our flagship Category 1 Emergency Positioning Radio Beacons (EPIRB).
ACR has designed a patent pending release rod system,which does not depend on a battery, sharp blade, or a pyrotechnic device to release the beacon. This advantage allows ACR to offer an HRU that is individually tested to ensure that the HydroFix™ is
the most reliable HRU in an emergency situation.
All HydroFix™ units are tested to the same high standards and quality workmanship you have come to expect from ACR over the past 50 years.
When submerged in water between 5-13 ft.
(1.5 - 4 m), the HydroFix™ will disengage the rod allowing the Category 1 bracket to release the EBIRB.
ACR’s HydroFix™ is now part of the standard replacement kit for the following EPIRBs* and brackets:
