High-Performance Thermal Insulation

Ultra-R™, Glacier Bay’s vacuum super insulation, delivers the maximum insulation

performance available on the market while using less space than traditional foam insulation. Ultra-R, with an R value

of R-36, provides 10 times the insulation value of foam, yet is only 1 3/8” thick. These panels rely on moderate vacuum and a special aerogel core material to achieve their insulation value rather than “trapped air” as do conventional insulation materials.

Ultra-R is a rigid, polypropylene-encased vacuum insulation panel custom-made to your dimensions. It can also be pur

chased with an optional fiberglass facing (on one or both sides).

Ultra-R offers many advantages over other thermal insulations including:

• Highest “R” value of any currently available insulation material
• Superior space and energy savings
• Exceptionally light weight
• Long life
• When combined with our ready-to-mount hatch lids, you can easily assemble your own ice boxes.
• Outstanding “R” value even if punctured

All Ultra-R^tm panels are custom made to any flat size. Polygons, curved edges and mitered corners are permitted. Beveled edges are not permitted. There is no limit to the size of a single panel. Panels come standard up to 30″ x 35′ with polypropylene facings. Larger sizes, fiberglass facings and hatch openings are can be fabricated at extra cost. Plumbing access holes are provided at no additional cost, but must be specified in the design. Remember, panels cannot be modified (ie. cut, drilled or punctured) once they have left the factory.

Standard Panels
Standard panel costs apply to custom designs in sizes up to 30″ x 35″ and are encased in a polypropylene outer housing.

Extra Large Panels
Panels larger than 30″ x 35″ (length and/or width) are constructed by compositing multiple individual panels inside the outer housing. The outside appearance remains that of a single, large panel and there is no loss of performance. However, due to the additional costs to make them, they are priced as “Extra Large Panel.” When panels are larger than 60″ x 70″ there is added charge.

Panel Thickness and Fiberglass Facings
An optional fiberglass facing is available for box “kits” and other applications in which the panel surface is to be used as the interior box liner. Finished panel thickness is as follows:

The [...]]]> Variable-Speed Brushless DC Generators – by Glacier Bay

Glacier Bay’s unique high power density generators are smaller, lighter, quieter, and more efficient than comparable conventional generators.  They incorporate over two decades of Glacier Bay’s pioneering high-efficiency power management technology originally developed for NASA, the Department of Energy (DOE), and the Defense Advanced Research Products Agency (DARPA).

The keys to the generator’s high performance are its intelligent controllers, high-efficiency permanent magnet generator head, and active rectification boost module.  Conventional generators run at a constant speed and require large, heavy engines which are oversized for the load in order to survive the harsh task of operating with light loads for extended periods. Constant speed engines operate inefficiently when partially loaded, requiring a separate generator to closely match each load.  Glacier Bay’s generator incorporates intelligent controllers that vary engine speed depending on the load, enabling the generator to produce comparable power levels from a significantly smaller and more efficient engine, and to operate reliably at high efficiency over a wide power range.

The smaller engine is lighter, takes up less space, uses less fuel, generates fewer pollutants, and is quieter than those in conventional generators. The generator is up to 18% more efficient generating AC and 40% more efficient generating DC relative to traditional generators. The benefits of load-following technology have been known for decades, but it took Glacier Bay–calling on years of system engineering, controls, and power electronics experience–to design the innovative controllers necessary to fully utilize the inherent benefits of load-following generators.

In addition to offering superior weight, size, and performance benefits, a single Glacier Bay generator can meet a range of different power needs, saving you the multiple SKU’s you would have to assort using conventional technology.  Wouldn’t you rather use one product to meet a variety of needs, than have to stock numerous products and spare parts?
The future of mobile power is Glacier Bay.

Revolutionary load following DC generators

• Light weight – 40% lighter than conventional generator technology
• Size – 50% the size of conventional generator technology
• Superior fuel efficiency – from 18% – 40% more fuel efficient
• Quiet – Smaller, quieter engines mounted in virtually silent sound enclosures, lined with Glacier Bay’s patent-pending Ultra-dB™  acoustic insulation
• Extended service intervals – up to 500 hour
• One generator meets a wide range power needs – Load-following ability allows one generator to meet a wide range of power requirements, eliminating the need for multiple generator sizes and the associated service parts

Ultra-dB™ high performance acoustic insulation provides superior noise reduction and is 48% lighter and 25% thinner than other laminate acoustic insulation. Its six-layer design and random-composition damping layers block a wider spectrum of frequencies. When sound waves strike Ultra-dB, the particles in the damping layers dissipate the energy while the foam layers absorb and lower the remaining sound. Ultra-dB is applicable for a wide range of uses and successfully dampens noise in marine, HVAC, research, construction and other commercial applications.

Ultra-dB acoustic insulation delivers:

• Superior noise reduction across a broad spectrum of frequencies
• Unique, six-layer noise control solution
• 48% less weight and 25% less thickness
• High quality polyether foam provides 4x the life of polyurethane
• Convenient, self-adhesive backing for easy installation
• More flexible than traditional foam acoustic laminates
  

A wide frequency band solution
While many materials block sound, no single material blocks noise. The sound spectrum analysis above,  shows a 3-cylinder diesel engine running at 2,800 RPMs. The noise it emits includes frequencies ranging from 22Hz to over 11kHz. Because no single material can effectively block all these frequencies, the only way to attenuate this kind of extreme noise is to select a combination of materials which work together across a broad sound spectrum.

The physics of multilayer acoustic insulation materials
Noise is energy and, although you can’t get rid of energy, you can change its form. Acoustic insulation changes the energy contained in sound waves into heat. The more effectively it does this the greater the sound reduction.

Traditional multilayer “foam-vinyl-foam” insulations are an attempt to attenuate a wider range of frequencies than possible with one material alone. Manufacturers often describe individual layers by their functionality, hence the “absorption-damping-decoupling” layers.

The “absorption” layer (nearest the noise source) is comprised of foam which is of a density that allows it to attenuate higher frequency sound waves.

Because the resonant frequency of foam is quite high (above 250 – 500 Hz), lower frequencies pass through virtually unaffected. Attenuating lower frequencies is much more difficult and is the primary function of the “damping” layer.

The damping layer in conventional sound materials is a typically very heavy (lead or a filled vinyl) composite that relies on high mass to provide a lower resonant frequency and convert the energy contained in these waves into heat. Unfortunately, the weight of the damping layer causes a new problem. If the vibrating mass transfers this energy to another surface (such as a wall or bulkhead) the noise is simply transferred through. It is the job of the “decoupling” layer to prevent this.

The Ultra-dB difference
While conventional acoustic insulation materials work well if you use a sufficient weight and thickness, Ultra-dB provides greater noise reduction using thinner, lighter materials. Rather than using a uniformly molded sheet, our damping layer is a composite made up of randomly adhered elastomeric particles of varying sizes, shapes, weights, densities and durometers. When sound waves strike, different particles within the layer resonate depending on the frequency of the wave. At any given frequency only a fraction of the particles vibrate. Each vibrating particle is loosely suspended between other particles, most of which do not resonate at the same frequency. This permits the energy contained within the vibrating particle to be dissipated into the adjacent material rather than through movement of the entire layer.

The result is better attenuation over a wider frequency range.
