In the world today there are many different electric motors. We all see equipment that is powered by motors, whether you realize it or not. It might be a pool pump that powers water through a swimming pool, to a lathe in a woodshop that is used to make bowls or pencils. These motors typically average in size to about 5 HP. Then there are the larger electric motors that are used like vehicle motors, airplane motors. And you’ll hear of electric motors commonly used in business today that are commercial and industrial electric motors like those you might find in factories or warehouses and are used to power large machines. Electric motors are a big part of how businesses and factories are powered, but like everything today, there will be times when something goes wrong and you will need to have parts repaired or replaced on the motor.

Electric motor repairs usually need to be done by qualified repairmen or companies that specialize in electric motor repair. If you have an electric motor that is especially large and heavy, you will need to verify with the repair shop that they have the necessary equipment, like cranes, to be able to move your motor.

When your pool pump motor runs dry and burns up you know you can call your pool technician and he will repair the problem for you or if you need an electric motor repaired on any of your woodworking machines, you generally call in a repairman who works on small machines. When larger more powerful motors develop problems and need parts and repair work it often entails a larger scaled motor repair division found in companies that special in industrial and commercial machine motors.

These companies tend to have repairmen and technicians who are skilled in working on both A/C motors and D/C motors as well as motors that have a higher horse power. They will also have all the necessary tools and equipment needed to repair your motor back to a pristine state. Many of the large scale electric motor repair shops will have the ability to put a high build epoxy varnish treatment on repaired items as well as to do a Core Loss test, and equipment that can do vibrations testing on the electric motors and parts repaired.

At times your motor will have become so damaged, often because of too much heat that damages the insulation or because the winding has been cut, that it will need to be rewound. Almost all electric motor repair shops have the equipment required to test for this and can offer you motor rewinding services. Most shops should be experienced enough to be able to rewind all types and sizes of motors, such as for both A/C and D/C motors. With any electric motor repair work done, make sure to check is the shop is a certified warranty repair facility for your type engine manufacturer. If your machine is still under warranty, it is going to be very important that you use a shop that can do certified repair work on your engine.

Oxidizers are units that are used to process the noxious gas emissions from industrial plants, by oxidizing them with high temperatures, prior to their release into the atmosphere. These oxidizers are used in a number of industries and applications, including paper printing, petroleum refining, and other applications that produce various pollutants such as volatile organic compounds (VOC), Nitrogen oxides (Nox), and Carbon monoxide. All oxidizers can be categorized into two types based on their operation, thermal oxidizers and catalytic oxidizers.

Thermal oxidizers work on the principle of combustion and use the high temperatures produced by combustion to break down the hazardous gases into clean air for discharge. Based on their heat recovery system, oxidizers are essentially of two types – the recuperative thermal oxidizer and regenerative thermal oxidizer (RTO).

The recuperative-type uses an integrated conventional heat exchanger, known as the primary heat exchanger, as its heat recovery system and the recovered heat is used to preheat the incoming exhaust gas stream. In some cases, an additional heat exchanger, called the secondary exchanger, is also included in the flow after the primary exchanger to heat another fluid used in the process.

The regenerative-type uses a set of ceramic heat transfer beds for its heat recovery purposes. Besides being more durable and offering a longer usage life as compared to the heat exchangers used in the recuperative-type, the ceramic beds also provide improved thermal efficiency. The thermal efficiency of the regenerative thermal oxidizer is around 90% to 95%, as compared to the 50% to 75% offered by recuperative thermal oxidizers. This increased thermal efficiency leads to energy savings and reduced operational costs.

A specialized version of the RTO, known as the regenerative catalytic oxidizer or the RCO, uses ceramic media coated with precious-metal catalysts that help in the oxidation of the gas stream at comparably lower temperatures. This type of oxidizer, with its lowered operational temperatures, offers even greater reductions in operating costs.

Another type of thermal oxidizer used in some cases is the direct-fired thermal oxidizer, which lacks heat recovery system of any kind, making this oxidizer least capital-intensive. However, the lack of a heat recovery system makes this type of oxidizer expensive to operate. The catalytic oxidizer works by utilizing catalyst beds of precious-metal coated ceramic honeycombs or beads to enhance the rate of reaction of the exhaust gas stream.
