Gardner Denver understands that rotary lobe blower packages represent a major acquisition and therefore must represent the best possible net present value to your business. Many considerations such as total purchase price, maintenance costs, personnel support costs, and utility requirements per unit of performance all factor into the overall decision. |

Energy Efficiency and ROI

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 Premium 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.

Air Smart Controller and Cost Avoidance
|
  |
|
The goal of any business is to be as productive as possible. While energy optimization is key, reliability is also a must. When considering the fact that many of today’s operational costs such as facilities, utilities and personnel are fixed, any time production is down or even constrained, costs to business can be significant. Costs avoidance and the ability to minimize or even eliminate unplanned stoppages helps to manage one of the most costly risks to a business. All Gardner Denver blower packages are fitted with an Air Smart control system with these very issues in mind.
Air Smart Controller Capabilities include:
- Measurement of inlet and outlet air pressure
- Measurement of inlet and outlet air temperatures
- Measurement of blower oil temperatures
- Measurement of blower oil levels
- Ongoing performance monitoring and reports show how the package is operating even when inside normal parameters
- Pre set operating parameters can be programmed with warning levels. If a warning level is reached, an advisory is sent before a unit reaches critical thresholds and shuts down thus maintaining run time
- In-built shut down protection should the blower reach pre programmed shut down thresholds
- In the event of a shut down of any kind a diagnostic report is prepared to show exactly how the package was operating prior to shutdown. This speeds up trouble shooting, diagnosis and maintenance and reduces downtime
- Pre programmable scheduled maintenance counters for filter changes, oil changes etc. allow you to proactively maintain your asset and be sure that your package(s) are running as efficiently and effectively as possible
- Ability to pre program run times and sequence packages for efficient operation that matches facility demand and spread the work between units for reliability.
- Ability to send information out and monitor the blower (or blowers) remotely.
- Ability to control the and change the speed of variable drives to match demand
All of this data is held in one easy to read control panel that can be clicked through and reviewed very quickly and easily. The Air Smart controller helps to manage your assets in a meaningful manner. Should anything happen to the blower, pre-cursory advisories should allow an opportunity to head any problems off before they occur. If there is a shutdown, the diagnostic history should point the service engineer to the trouble spot quickly to allow and service work to be conducted and the blower to come back online.
In short, the Air Smart controller moves blower management from a reactive state into proactive management. This in turn, helps to support ongoing cost avoidance. Furthermore, ongoing self monitoring reduces the time (and manpower) required to monitor each blower package and allows personnel to engage in other activities.
