Our standard skid unit comes with a 10 horsepower, 3-phase electric motor. However, many of our agricultural customers and other bulk LPG storage customers in rural areas have access to only single-phase power. So naturally, we often get asked how someone with single-phase supply can use one of our skids.
Here are two options we usually suggest for someone with single-phase supply.
Option 1 – We can build a skid unit with a 7.5 horsepower, single-phase electric motor. It has to be an explosion proof motor, that’s why 7.5 horsepower. The 7.5 horse motor is paired up with a 2-inch pump which results in slower fill rates (approx 70gpm) – about half as fast as the 3-inch pump, 10 horse motor (approx 170gpm).
Option 2 – You can have an electrician on your end install an inverter that will convert single-phase supply to power the 3-phase motor. We’ve been quoted about $5000 for parts and electrician for the inverter install. The inverter adds to project costs, but you’ll get about 2x faster fill rates using the bigger motor and pump.
