Our Story

In 1993, while working on a friction welder retrofit project at John Deere, a startup system integrator known as Grace Engineering was presented with a hazardous electrical safety issue. The machine I/O was located in the front while the electrical panel with a 250 horsepower drive and a 400 amp main feed was inconveniently located at the rear of the machine. 

The company led by founder and inventor, Phil Allen, would become known as Grace Engineered Products when it devised and manufactured an innovative solution for panel interface connection called GracePort®.

With the advention of the GracePort®, Grace began to hit its stride as a pioneer in the electrical safety industry by developing GracePESDs® consisting of absence and presence of voltage indicators and portals. Next, came the GraceSenseTM Predictive Maintenance product line of Preventative Maintenance solutions like the Hot Spot Monitor and IIoT Smart Sensing devices to predict unplanned downtime and revolutionize maintenance technology and personnel safety techniques.  

In 2020, the company changed its name to Grace Technologies to align with the modern product offerings. Today, Grace manufacturers and delivers electrical safety innovations and predictive maintenance solutions through a global distribution network and sales presence operating in 60+ countries around the world.
