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.…

3 Ways To Protect Your Home From a Storm

No matter where you live in the world, you are bound to encounter a big storm from time to time. However, did you know that even a small storm can cause significant damage to your house if you haven’t adequately prepared it? Over time, homes and properties deteriorate and need to be maintained. Following a regular maintenance schedule will give you peace of mind and will save you money in the long run.

Check Retaining Walls

A landslide is a quick way to ruin anyone’s day. The sheer volume of dirt and rocks can quickly demolish anything in its path. If you have a retaining wall anywhere around your home, it is important to maintain it regularly. Look for cracks in the stones or the mortar around them. Also, look for bulges or bowing of the wall. If you see a change in the stones, it could mean that the soil is shifting, and you could have a rupture at any time. If you are unsure how to repair the wall yourself, look for geotechnical engineering services Union City CA.

Replace Loose Shingles and Siding

Before every storm season, it is essential to evaluate the health of the outside of your home. Look for damaged or missing shingles. If a shingle is damaged, it has a better chance of pulling off entirely in a storm. Any areas that aren’t protected by shingles are opening your roof to even more damage from wind and rain. Furthermore, look for issues in your siding. Seal any cracks that might let water in and secure any areas that have gotten loose.

Give the Water a Place To Go

Gutters are an often overlooked part of a home, but they serve a crucial role in its preservation. Gutters allow rainwater to be collected and whisked away from your home instead of puddling around it and causing issues. If gutters aren’t cleaned regularly, then the water will overflow and potentially puddle near the foundation, which can cause major problems after time.…

3 Things Geotechnical Engineers Do

Geotechnical Engineers

The infrastructure present in modern cities and towns could not exist without the labor of geotechnical engineers. Many of them work for environmental engineering companies and have used their knowledge to develop well-supported buildings and complex systems. Check out this list of three things geotechnical engineers do.

1. Investigate

Geotechnical engineers will investigate the conditions of the area where developers want to erect a structure. They will look into the dynamics and vibration of the soil in said area. They will engage in surface and subsurface explorations and collect soil samples that they send off to laboratories for further analysis. The aim of these investigations is to gather as much information as possible about the properties of a worksite. Such investigations often reveal what will occur on the site during an earthquake.

2. Design

Engineering design plays an important role in the field of geotechnical engineering. Technicians have to plan out specific projects while taking certain factors into consideration (e.g., time, size, and shape). Geotechnical engineers have designed foundations, slopes, and pavements. Some have crafted projects that took into account terrain hazards while others have developed ones that had water retention capabilities. Many have taken on projects for structures designed to withstand powerful seismic events.

3. Construct

A multitude of geotechnical engineers have helped build roadways, tunnels, levees, and embankments. After they investigate the behavior of the soil and rock in certain locations and design structures that are sturdy and stable, they carry out various construction projects. While doing so, they utilize materials that work in synergy with the elements they are placed in. They position these materials in ways that keep those who end up walking or driving upon them safe and secure.

The work that geotechnical engineers do is extremely vital. These engineers have helped a plethora of individuals and businesses.…

Where the Vacuum Valve for Pumps is Being Used?

Technology brought us so many advancements over the last 100-150 years that if a person manages to travel through time and arrive today, they would be completely shocked how we live. On the other hand, we take these advancements for granted and most of us don’t even know how things work.

If we’re talking about vacuum pumps that are used all across the industries, we’re going to be stunned by how much we depend on this technology. Doing your own research takes a lot of knowledge in the field of engineering and science, so you can say it’s not easy to fully understand everything.

In this article, we’re going to help you make sense of this technology and learn more about vacuum valves and where they find the best use. We will talk more about industrial vacuum pumps and help you learn about this field. Follow up if you want to know more about these topics.

What is a vacuum pump?

As the name suggests, these machines are pumps that work under pressure and vacuum. They are used to push gas or liquids from one place to another using the vacuum as their main force to do it properly.

There are four main categories under which different ones fall. Here they are listed:

  • Positive displacement pumps
  • Regenerative pumps
  • Momentum transfer pumps
  • Entrapment pumps

All four are used across many different industries, but it seems like the first ones are most commonly used. The reason for this is that these offer the most function, are easy to be made, and they work the best. This is why most companies use this kind and if you’re in some of the common businesses using one, you’ll probably consider this type yourself.

The vacuum pump uses electricity or gas, depending on its use and the features. You can say that there are so many options, that no one can study all of them to perfection, which is why most people focus only on one or several models and become experts in them.

The pump is driven when the power added to it drives the valve which is under pressure. It is then releasing the gas or the liquid to the other side creating a vacuum behind it. As the process repeats, the machine can pump new material constantly.

This is how the manual water pumps were made back in the day. With constantly adding pressure to the handle, the mechanism manages to extract water from the ground or the well. The water driven by the vacuum goes up preventing the dirt to come with it.

When the water is high enough it simply goes through the faucet and is ready to be used. When there’s enough water, the person will release pressure on the handle and use the extracted water from the well. That’s how science and great engineering work. See more about them on this link.

What is a vacuum valve?

The main part of the entire machine is the valve. It is the one that is constantly moving and producing the gas or the liquids to move from one place to another. If we continue using the same example from the previous paragraph, the valve is the one part that allows water to go through it and come out through the faucet.

It is specially designed so the water can go through it by moving it. The valve moves around itself providing water to go to the back end but keep the vacuum pressure on the other part. That’s how more and more water can keep coming up without losing momentum.

Of course, modern technology invented so many advanced techniques, but it all came from this simple method. There’s no need for adding power to this machine and it can be done manually. Modern machines use fuels or electricity to keep the pump going without stoppage and drive a lot more material.

Where are vacuum valves and pumps used?

So many industries find tremendous value from them. On top of it, ordinary people in need also have great use. For example, there are so many people who need water extraction in places where there’s no water line and system that provides fresh water. These people are creating their personal wells by using machines like these.

Another extremely useful moment is the flood extraction. Basements in areas where it is common to experience flood almost always have attached and ready pumps that will extract the water using this system. They work on batteries, so they don’t require power lines.

Instead of seeing the entire place ruined, these machines activate themselves the first moment they sense that there’s water on the ground. Designed specially to extract water from lower parts to outside areas, helps people keep their premises safe.
