Metals & Heavy Industry
Energy audits for metals and heavy industry plants with large motors, drives, process heat and demanding power quality.
Where energy usually goes
Illustration
- Large motors and drives
- Process heat
- Compressed air
- Power quality and power factor
Systems 2R audits here
- Air compressor · compressed air takes a lot of electricity to make
- Receiver tank · stores compressed air and evens out demand
- Air leak · leaks waste compressor power around the clock; 2R's tool: Ultrasonic leak imager
- Production machines · use compressed air and power at each station
- Conveyor line · moves product between stations, sometimes while empty
- Motor + VSD · speed matched to the line; motor speed checked with a Lutron DT-1236L tachometer

- Transformer (utility intake) · where the building takes power from the grid
- Main switchboard (MSB) · distributes power to the whole building
- Power logger · logs kW, kWh and power factor over days: Meatrol Mi550 / Fluke 430 Series II
- Load profile · the logged data shows when and where energy is used
- Sub-boards · feed each area or system, measured one by one
- Loads · chillers, motors, lighting: where the energy ends up
