Installation and Energy Savings Example

Application

An oil refinery utilizes thousands of pumps throughout the facility, many of them in hazardous areas. In an effort to improve their bottom line, the owners would like to control the pumps with VFDs and capture the energy savings they provide.

Problem

There is no space in the non-classified control room for the VFDs. Also, the cost to engineer and install conduit and motor cable from the non-classified area to the pumps in the hazardous area is prohibitive.

Solution

Install Cooper Crouse-Hinds ACE Series Explosionproof VFDs right next to the motor and pump, tapping into an existing 480V supply.

Benefit

By using a VFD to optimize pump flow, significant energy savings are realized. Additionally, by installing the VFD next to the pump and motor, installation costs are greatly reduced.
