Nova Scotia Mechanical 40 PDH Discount Package 2

This online engineering PDH course provides comprehensive information on cooling water systems and describes different types of cooling towers, their mechanical components and the problems associated with cooling water.

A cooling tower is a device used in industry to cool hot water (by partial evaporation) before reusing it as a coolant. Water directly contacts surrounding air and a very small part (1-2%) evaporate. This evaporation increases the air temperature and humidity and decreases the temperature of the water making it possible to cool below the normal air temperature. Although this heat is usually transferred to a cool, flowing volume of water, final rejection is always to the atmosphere and, invariably, is accomplished by some form of heat exchanger.

The machines and processes of industry, as well as the air-conditioning systems for buildings generate tremendous amounts of heat, which must be continuously, dissipated if these machines and processes are to continue to operate efficiency. Water cooling is the most efficient method of dissipating heat.

This online engineering PDH course provides guidance on the basic operating principles of 2-cycle and 4-cycle diesel engines. It explains the fundamentals and theory of operation of engine governors, fuel ejectors, camshafts as well as typical engine protective features.

Today most facilities require some type of prime mover to supply mechanical power for pumping, electrical power generation, operation of heavy equipment, and to act as a backup electrical generator for emergency use during the loss of the normal power source. Although several types of prime movers are available (such as gasoline engines, steam and gas turbines), the diesel engine is the most commonly used. Diesel engines provide a self-reliant energy source that is available in sizes from a few horsepower to 10,000 hp. Relatively speaking, diesel engines are small, inexpensive, powerful, fuel efficient, and extremely reliable if maintained properly.

This 4 PDH online course is applicable to mechanical engineers, plant operators, maintenance personnel, and technical staff who are interested in gaining a better understanding of diesel engine fundamentals.

This online engineering PDH course provides fundamental knowledge of heat pumps so that you can make more informed decisions in choosing the correct system. The course covers the fundamentals, components, applications, installation of air source and geothermal heat pumps. Prior knowledge and a basic background in refrigeration and air conditioning will be helpful.

A heat pump is an electric device, which extracts heat from the air, ground or water and transfers it into the building. It is one of the most effective ways of heating water and indoor air while at the same time providing cooling (e.g. air conditioning), making them ideal for use in places where both air conditioning and heating are required.

A heat pump uses the principles of vapor compression refrigeration cycle to transfer heat from one place to another exactly in the same way as an air conditioner does. The beauty of these pumps is that they use the same refrigeration cycle for heating and cooling. Using a reversing valve, they change the coil serving as the condenser and the one serving as the evaporator. In cooler climates, people often purchase these pumps for use only as heaters. These units draw the heat from the ground or air and are often used commercially to heat offices and large apartment communities.

Their reputation started to grow since 2008, when heat pump sales in the United States and the Scandinavian countries have risen 40%. In some European countries heat pumps have already taken a significant proportion of the market for heating appliances and this is likely to be a long-term trend.

This online engineering PDH course provides guidance on heat tracing, its different types (electric, steam, hot water), and its advantages and limitations.

The term heat-tracing refers to the continuous or intermittent application of heating pipelines, tanks, vessels or other equipment used for storage or transportation of a product (liquid, powder or gas). The purpose of heat tracing is to compensate or make up for the heat loss to the surrounding atmosphere in low ambient temperature climates. Some applications for heat tracing include; preventing fluid from freezing, maintaining process fluids at pumpable viscosities, preventing formation of hydrates and waxes in hydrocarbon liquids (oil, etc), and also sometimes to preheat part of a fluid system prior to initial startup or after a primary heating system shutdown.

The heat tracing is generally accomplished by employing electric or steam tracing and insulating both the process fluid pipe and the tracer together, using appropriate insulation materials and metal lagging. The decision between electric and steam heat tracing depends on various factors and this course outlines the pros and cons of both the methods.

This 4 PDH online course is applicable to process, mechanical and electrical engineers, operations & maintenance personnel, as well as consultants and contractors who construct, build and manage facilities involving heat tracing systems.

This 5 PDH online course is applicable to mechanical and chemical engineers, nuclear facility operators, maintenance personnel, and other technical staff who are interested in gaining a better understanding of the operation of the different mechanical equipment.

This online engineering PDH course covers the basic operating principles of pumps, discusses their different types, and explains their installation and maintenance methodologies. This course also presents the auxiliary components such as the different types of valves, piping and other accessories typically used in pump systems.

A pump is a device that uses an external source of power to force the fluid to move from one place to another. A pump develops no energy of its own; it merely transforms energy from the external source, such as a gasoline or electric motor, into mechanical kinetic energy, which is manifested by the motion of the fluid.

A valve is any device used to control fluids in a closed system, and is typed or classified according to its use in a system. This course will discuss valve construction and the most common types of valves used in the industry.

The control and application of fluid power would be impossible without a suitable means of conveying the fluid from the power source to the point of application. Fluid lines used for this purpose are called piping. They must be designed and installed with the same care applicable to other components of the system. To obtain this desired result, attention must be given to the various types, materials, and sizes of lines available for the fluid power system.
