Anhydrous Ammonia Refrigeration and the Importance of Purity...

Posted by , on Nov, 2018

An anhydrous ammonia refrigeration system is highly efficient and an eco-friendly choice for industrial facilities today. The term “anhydrous” means to not have any moisture or water in the system. In Greek, it means “without water.” In fact, it is very important to keep moisture out of your ammonia (NH3) cooling system. Here are some helpful tips for keeping it pure. Understanding NH3 Properties Ammonia’s chemical symbol is NH3, and this means each molecule contains a single atom of nitrogen and 3 atoms of hydrogen. NH3 makes a good cleaner and chemical compound because it is easily dissolved in water. When you mix water (H20) and NH3, you get a compound called ammonia hydroxide, and it is commonly found in many household cleaning products. However, this solution is highly diluted to keep toxicity to a minimum. Ammonia and Purity In order to maintain efficiency and properly cool, anhydrous ammonia refrigeration must contain no water. In fact, it needs 99.95 % purity or 33 ppm (parts per million). Some refrigerating systems use oil in the refrigerant to keep parts lubricated. However, NH3 systems cannot have much oil in them. In fact, they cannot contain more than 2 ppm. How do Impurities Get in the System? There are several conditions which contribute to NHS system moisture contamination. For example, when a technician charges the system or makes repairs to pipes, it can leave it open to moisture penetration. If valves have faulty packing, moisture can enter. Over time, NH3 breaks down, and water can sometimes form. Problems Too much moisture in an anhydrous ammonia refrigeration system can cause freezing which may lead to catastrophic results. Components can get stressed, and this may cause leaks. Ammonia leaks are dangerous because the fumes can create respiratory and skin problems. This is why you must maintain a moisture-free system at all times. Be the first to like. Like...

When to Call for Help with Refrigeration System Troubleshooting...

Posted by , on Oct, 2018

In industrial refrigeration, time is money. Regulations on how long your refrigeration system can be out of range are very strict. And, any downtime may mean you are losing product fast. This is why it is so important to get help for any initial signs of a problem as soon as possible. Refrigeration system troubleshooting is not something to do on your own. Rather, it is by far more important to call a team to come to your location immediately for assistance. Signs You Need Help Of course, if your system is not working, it is critical for you to take steps to get it back up and working as soon as possible. However, in some cases, a local refrigeration company can offer some help to you while you wait for full service. Refrigeration system troubleshooting includes determining where the underlying problem is. In many cases, this may have to do with the system’s electrical system. It may be a concern with the motors. Or, you may need to defrost it to allow for the system to become unblocked with ice and buildup. This is not something to tackle on your own. Rather, it is best to hire a company to do the work for you. They work with you one on one to determine the best course of action to getting your system back up and working again. This means making repairs or simply fixing the underlying problem with new components. In an industrial or commercial setting, you cannot afford to put off getting the help you need. Refrigeration system troubleshooting requires understanding the specific make and model of your system and then working with a trusted and experienced team to help you get it back up and running again as quickly as possible.

How to Expand Your Metal Machining Services

Posted by , on Oct, 2018

Do you run a small machine shop but have dreams of a bigger operation? If you could expand your business, you may attract more customers and make more profits each month. There are a number of pitfalls to consider with expansion, but most of them are overcome with the right business strategy. Here are some ways to increase metal machining services without putting your company far into the “red.” Increased Production There are four effective ways to raise your production: 1. 24/7 – you could run your shop 24 hours a day and 7 days a week. However, you need to pay out a lot of overtime pay or hire more machinists or workers. This may cost you a lot of money in employee benefits or additional pay, and you may need to raise prices. 2. Automate – do you have manual machines in your shop? You may want to consider buying or leasing some CNC machines. However, this can add to your operating expenses, and you may not have the room in your shop. 3. Expand the shop – if you add on or move to a larger shop you have room for more machines. However, expansion is expensive and is not always possible for a small business. 4. Outsourcing – hiring a trusted metal machining service is a viable option for just about every machine shop. It costs you nothing extra, and you pass this cost on to the customer. Why Outsource? When you hire a trusted shop, you can instantly increase your production. Also, there is no obligation to order a specific amount of materials. You can buy what you need and take your time expanding your metal machining service. You do not have to hire more employees nor do you need to pay out overtime money. You do not need to come up with additional working capital either. Be the first to like. Like...

When Welded Hydraulic Cylinders Function Best

Posted by , on Sep, 2018

The manufacturers of hydraulic cylinders or actuators produce a variety of types to meet the demands of their customers. They customize and produce standard cylinders to ensure each industrial concern receive the right system for their application. While some industries prefer one type to another, in some instances and applications, the optimal options are welded hydraulic cylinders. Why Choose Welded to Other Types? In the case of welded cylinders, the barrel (or body) of the cylinder is welded to the cap directly. It does not feature tie rods. The welding also attaches the ports or fittings to the barrel. The manufacturer may also fasten the head or gland to the body using welding, although other methods are common. Arguably, its design makes it superior in several ways to other types of hydraulic cylinders. It provides certain advantages when using including: * Durability * Minimal Maintenance * Longevity * Versatility – for use with low and, more commonly, medium to heavy loads * Dependability * Compact design * Aesthetics It may also be the major option when the space is confined and small. Such qualities are responsible for their popularity in a variety of industrial applications. When Welded Hydraulic Cylinders Function Best No doubt remains about what specific area welded cylinders dominate. This is the mobile hydraulic equipment market. It offers maximum performance and demonstrates clearly its best capabilities when performing designated tasks in such industries where mobility is an integral component of the application. As a result, welded cylinders are in * Agricultural machinery * Construction equipment * Marine gear * Mining mechanisms It is ideal in snowplows, trucks and various types of lifts. Welded Hydraulic Cylinders It is advantageous, for certain industries, to choose a welded over a tie rod or other type of hydraulic cylinder. Its compact nature, durability, longevity, and dependability are ideal for certain applications. Its qualities make it the most popular choice for mobile equipment. 3 people like this post. Like...
