Saving Energy Through The Use of a Variable Frequency Drive (VFD)

This video is a quick demonstration of how Emerson Control Techniques variable frequency drives can help you realize substantial energy savings. Applying variable frequency drives to centrifugal fans and pumps offers extremely good energy saving opportunities — as high as 60% in some applications.

Saving Energy Through The Use of a Variable Frequency Drive (VFD)

Control Techniques Americas has just released a new 6-minute “Energy Savings” video demonstrating how its variable frequency drives (VFDs) used with centrifugal fans and pumps offer extremely good energy saving opportunities – as high as 60% in some applications (payback can be as little as 3 to 6 months in applications with long periods of low-flow operation).

The savings potential is high in these variable torque applications because centrifugal fans and pumps follow what are called the “Affinity Laws.” These laws of physics basically state that the flow is approximately proportional to speed but the power consumed is roughly proportionate to the cube of the speed. The video shows that even a slight speed reduction results in a comparatively large drop in power consumption. (An added benefit of reducing speed is that audible noise is reduced by the fifth power of the speed.)

Features of Control Techniques AC drives that are particularly useful in fan and pump applications include:

• Dynamic volts-per-Hertz control for maximum energy savings.
• Built-in energy metering quickly shows energy and cost savings achieved without having to add expensive external meters.
• Bypass system resonant frequencies through simple drive set-up.
• “Ride through” power supply dips.
• Built-in independent PID control regulates system variables such as pressure based upon transducer feedback, eliminating the need for expensive external controllers.
• Onboard PLC functionality eliminates the need for an external PLC.
• Free- setup, commissioning, programming and diagnostic software tools.

Integra Enclosures

Product Line Overview

Integra enclosures are offered in three basic product lines. They are the Premium Line, the JIC Line, and the Telecom Line. All enclosures are injection-molded, engineered thermoplastics, designed to provide the best combinations of strength, durability, design features, and aesthetics.

The Premium Line, JIC Line, and Telecom Line all share the following features:

• Warp-Resistant Covers
  All Integra covers are molded with a slight doming in the covers. This works to ensure that the cover remains flat at the sealing surface, eliminating a chronic problem found in other non-metallic enclosures.
• Clear Covers
  Each of the Integra product lines offers enclosures with crystal clear covers. Clear covers provide a superior alternative to traditional window kits, as well as provide more design flexibility and product differentiation opportunity.
• EZ Hinge
  Integra hinged covers are 100% non-metallic, strong and durable, and easy to remove and replace. And, all hinged covers provide a full 225 degree door swing, providing full access to the inside of the enclosure.
• Unique Panel Suspension Capability
  Integra has developed and patented (Patent No. 6,604,798) a unique panel suspension feature. This system allows the placement of subpanels at any height within the enclosure, as well as the stacking of panels. It also works well to support the installation of dead front panels. This system is easy to install and very sturdy.
• Molded-In Mounting Bosses
  All Integra enclosures feature multiple molded-in mounting bosses designed to accept #10 self tapping screws for the installation of DIN rail right to the enclosure. No more need for sub panels if all your components are DIN rail compatible.
• NEMA Ratings and Underwriters Laboratory Listings
  All Integra enclosures are NEMA 4X. Our Premium and JIC Lines are UL/ C-UL-50 Listed for types 2, 3, 3R, 3S, 4X, 12, 13, and Marine Use. With four cover screws, these enclosures are type 6/6P. Integra is listed as Cabinet and Cutout Boxes (E207562) and Junction and Pull Boxes (E229365).
• Stainless Steel Latching
  Enclosures within the “HL Series” of each line feature stainless steel locking latches that are bolted in place at the factory. This provides a level of security that can not be met with pop rivets or slide-on latches.
• Modifications
  Full modification services are available at Integra, including machining, custom panels and custom colors. Call us to discuss your unique requirements.
• Packaging
  Standard packaging is one unit per carton, packed to ensure safe delivery to your location. Or, if bulk packing or other packaging is needed, call us and we can work to meet your requirements.
• Machining Capabilities
  Our capabilities at Integra Enclosures include machining to match a specific need. Contact us to discuss your exact requirements and our standard machining tolerances.
