Total cost of ownership includes everything from initial investment, installation, maintenance and utility costs. The initial package cost forms a small part of the cost of ownership equation. Over a five year period, up to 78% of the total cost of ownership of a rotary lobe blower package will be energy costs.

Operational efficiency is key to overall productivity and raises questions such as: How does my equipment perform in terms of utility consumption and how much more important will utility consumption become in future periods?
Sizing equipment to efficiently meet demand is therefore crucial, a fixed speed blower running idle (blowing off to atmosphere) typically consumes up to 90% of the energy required to run at full load. Paying for more machine than you need to meet worst case air demands could mean significant periods of energy waste when demand is not at peak.
Similarly under sizing a blower package that runs outside its optimal operating parameters increases energy utilization. Variable speed technology is therefore critical in allowing a blower to be turned up during peak demand times and turned down during off peak times. Gardner Denver rotary lobe packages have been designed extensively with energy efficiency in mind. Our goal is to deliver maximum operational efficiency, reducing costs and improving the carbon footprint of your business.
The IQ Blower package can incorporate many energy saving features including:
- TEFC EPAct High Efficiency Motor
- Integrated Variable Frequency Drives (inside the package) that turn individual blowers up and down in conjunction with demand
- Gardner Denver Air Smart control systems for optimal control and efficiency
- Remote monitoring capabilities
- Package sequencing capabilities that allow blowers to be turn on and off in sequence as dictated by overall facility demand avoiding the need to oversize systems for ‘worst case’ high demand scenarios Gardner Denver is an Energy Star Partner and is committed to developing products and introducing technologies that help conserve energy and protect the environment.
