OMG Roofing Products has introduced a line of retrofit roof drains, called Hercules-Plus, that feature integrated vortex breaker technology. Vortex breaker technology helps improve drain performance by improving water removal off the roof.

Independent performance testing shows that Hercules-Plus RetroDrains provide up to 2.5 times more flow capacity than original Hercules Drains without vortex breaker technology. Improved water flow off the roof also means that the drains get extra weight off the roof.

In addition, integrated vortex breaker technology reduces the chugging effect that occurs when a vortex collapses, which can overload the plumbing system. Hercules-Plus RetroDrains are available in four sizes; 3-, 4-, 5- and 6-inches with an optional TPO or PVC coated flange for direct membrane attachment. Strainer domes are made of cast aluminum. In addition, the safety yellow powder coat makes the Hercules-Plus strainer domes visible to help minimize rooftop trip hazards.
