Different Types of Insulation Used in Refrigerated Bulk Storage

Refrigerated Bulk Storage

One of the most important types of refrigerated storage in a commercial or institutional kitchen is walk-in storage. There are other types of refrigerated storage conveniently located near the preparation area, like sandwich units, pizza preparation units, or under-counter units. Still, the bulk storage is located in the walk-in cooler or freezer.

There are many different walk-in manufacturers, but one of the main things that set them apart is what kind of medium is located between the interior and exterior metal skins, the insulation that is used. The insulation medium used most often on the higher quality products is either polyurethane or expanded polystyrene insulation Houston. Some of the budget or less expensive walk-ins manufactured may use polyisocyanurate or styrofoam as insulation.

The efficiencies of the various types of insulation are measured by what is referred to as the R value. The higher quality and, consequently, the more expensive insulation has an R value of anywhere from R-25 to R-32. The higher the R value, the more efficient the insulation. While you will pay more money upfront for the higher quality insulation, you will pay less in energy costs to refrigerate a walk-in cooler or freezer over the years, and the return on investment is huge.

Other energy saving features that have an excellent return on investment are LED lights. The energy consumed by the cheaper incandescent lights is much greater than LED lights. Also, the LED lights have better coverage resulting in you needing fewer lights.

There are also refrigeration controls that are a great investment. Both coolers and freezers have evaporators that have to defrost regularly to operate correctly. The defrost cycle uses a lot of energy, so the less defrost cycles you need saves a lot of electricity. Units that only defrost on demand instead of a set number of times a day is a tremendous energy saver.

As you can see, there are times that you are better off spending money up front to save money operating costs over the lifetime of your refrigerated storage.…

Here’s How Braided Composites Are Helping to Shape the Future

Braided Composites

Divided we fall, united we rise. That saying is perhaps a bit cliché but when it comes to material sciences, it often proves true. Many material science companies now focus on composites, which are materials made with at least two “united” substances with differing characteristics. And among the most advanced composites are braided composites.

Composites, in general, are very important for modern science and industry. Often, scientists can improve strength or reduce weight, or both by making composite materials. When materials are mixed, it’s sometimes possible to hone and improve the strengths of the different materials while also reducing or eliminating their weakness.

Some researchers and companies are taking composites even further, using specialized braids containing numerous strains of fibers (with many of the fibers themselves being composites). Braiding strains tends to improve strength, and if desired, braids can often be made to be very flexible.

Go back a few hundred years and material sciences often involved choosing between different attributes. You might want something strong, for example, but strength often came at the expense of flexibility.

With modern composites, and especially braided composites, you can craft flexible, light materials that are also incredibly strong. These days, you’ll find braided composites being used alongside heavy machineries, such as construction equipment. You might also find such composites used in aircraft engines to strengthen and secure other materials

Heck, you might even find braided composites in sports equipment, like protective gear. In such applications, braided composites are popular because they’re light and flexible. This is great for athletes because they won’t be weighed down and can still move easily. These composites also dissipate energy.

In sum total, braided composites are increasing safety and leading to improvements elsewhere as well. And as researchers continue their work, composites will likely only improve.…

Do Small-Scale Renewable Energy Systems Work?

Renewable Energy Systems

Perhaps you’ve seen them in the distance as you drive along the highway: tall towers with a set of blades on top that spin gently with the wind. Wind power from turbines is increasing in many municipalities and countries across the globe, but is it possible to power a home with wind?

Wind turbines and solar panels are two major components of renewable energy systems. They are becoming increasingly popular because the energy from renewable sources is basically free once the panels or turbines are manufactured and installed, and these energy sources don’t produce environmental pollutants.

The use of wind power increasing on a large scale. The turbines are raised 100 feet in the air to take advantage of wind speeds at that level. Turbines may include NRG Systems tilt-up tower services to maximize effectiveness. They don’t take up as much room as acres of solar panels on a solar farm, and they require very little maintenance. But is wind power a realistic option for individual homeowners?

Just as solar panels have become smaller for residential installation, wind power has been scaled down, too. Rooftop wind turbines can supplement a home energy system, although they cannot replace the grid entirely. Smaller-scale home solar energy systems have net metering, which means they are connected to the energy grid. When the panels produce more energy than the home is using, the excess goes onto the grid. Rooftop wind turbines are connected to batteries rather than the grid, so they can help supplement a home’s power needs, but not replace the grid.

A hybrid system of solar panels, a rooftop wind turbine and batteries is the best solution here. When the sun is shining, the batteries will be charged, and the wind turbine will work when the wind is blowing. If the batteries can’t provide enough power, the house will draw from the grid. In some areas, power companies buy renewable power from homeowners when there is excess.

If it is properly sized, renewable power from wind and solar can run your home. This is the wave of the future.…

Building Your Own Airplane

constructing an airplane

You have your pilot’s license and are considering constructing an airplane of your own to take flying. There are many steps you will need to follow to ensure that you build a quality aircraft that will keep you and your passengers safe while you are in the air. Here are a few items to consider as you begin your build process.

Purchase a Kit

The simplest way to build your aircraft is to purchase a kit from a manufacturer. Research the type of airplane that you want. Think about the specific options that you want it to have, such as a certain number of seats, as you are shopping. Keep in mind that you may need special parts from a high-precision milling Santa Clara County company as you are working on your project. You will need to add these pieces to your final budget. Ask those you may know in the industry for recommendations on which package you should consider. They will be able to tell you if one type of plane is simple to put together and if one is more difficult. Once you have completed your research, reach out to the business that is selling the one you want and organize the transaction.

Take a Class

Contact your local airport to find out if there are any aviator clubs in your area. They will be able to offer you advice on your build as well as refer you to any construction classes that are being held nearby. These courses will assist you in assembling the craft so that it operates correctly. They can also help you through any sections that you may be less than sure of or lack training in. Some programs can also offer you space to work in if your garage or shed is too small. Having an experienced professional beside you from start to finish should have your airplane functional and in the skies quickly.…
