A Review of Variable Frequency Drives Variable frequency drives (VFD), which are also known as AC drives, frequency drives, inverters, speed drives, and micro-drives, are motor controllers capable of driving electric motors. The way this is accomplished is that the frequencies and voltages going to electric motors are varied. Brief Introduction to Variable Frequency Drives This type of adjustable speed drive is used primarily in electro-mechanical drive systems as a means of controlling torque but also AC motor speed by varying input voltage and frequency of the motor. Today, roughly 25% of electrical energy in the world is consumed by electric motors within various industrial applications. Throughout the past four years, the cost and size of variable frequency drives has been dramatically reduced thanks to power electronics technology. Taking a Closer Look The drive systems in which variable frequency drives consist are main drive controller assembly, drive/operator interface, and AC motor.
Gold Coast Photography | No.1 Portrait Photographers Gold Coast Waste Management Consulting | Zero Waste | Waste Audits Ontario What are FRP Fans? FRP is the acronym for “Fiberglass Reinforced Plastic” so in the case of FRP fans, these units are designed for corrosive air movement applications. Depending on the model, the construction might include a backward curved wheel and have a controlled construction of lamination. With this, the fan would comply with current industry specifications. Markets for FRP Fans There are different markets that use FRP fans, one being semiconductor manufacturing. For semiconductor manufacturing and most other industries, to be efficient and achieve success, it is vital that all systems run continually. The great thing about FRP fans is that they offer the level of ventilation needed for semiconductor manufacturing and other industries, as well as applications. Additional Industries Beyond the semiconductor manufacturing industry, FRP fans work well for other industries with examples listed below: Keep in mind that FRP fans are designed to be corrosion resistant.
Rapid Weight Loss Programs in Australia | 100% Safe Garcinia Cambogia Extract NZ | No #1 Weight Loss Supplement in NZ Introduction to Electric Duct Heaters Electric duct heaters are used around the world for industrial and commercial markets. Examples of heaters available include VAV equipment, air handling units, water source heat pumps, and light/heavy commercial rooftop units. When looking for duct heaters, it is imperative to choose a well-established company, one that guarantees all products are properly engineered and tested according to current industry standards. Applications for Electric Duct Heaters Within the different markets that use electric duct heaters are various applications. Examples of Heater Characteristics Every heater has unique qualities and characterizations. • Basic and more cost-efficient duct heaters are generally limited to size with the maximum being 36×36 inches • Custom heaters that measure up to 120×144-inches are also available, to include a number of options for accessories • Custom duct heaters also up to 120×144-inches that feature remote control panels

With a flow-through type, water flows through the unit and then drains out while for a reservoir type a reservoir or water is used while a rotating drum introduces moistures as needed. There is also a steam humidifier, but the other two types are more commonly used. The nice thing about using a flow-through humidifier is without standing water in the reservoir there is no risk for the growth of bacteria. This type of humidifier can also be connected to the hot air supply or air return duct as preferred, using a supply take-off duct that bypasses heated air to the humidifier by using natural pressure. Regardless of the type of gas humidifier, moisture from water is introduced and then evaporated into the warm air stream. Design and Features of Gas Humidifiers Although all gas humidifiers work in much the same way, there are differences based on the exact model purchased.

In HVAC systems, fans use roughly 40% of all electricity. The problem is that even by following all of the proper procedures in selecting fans for HVAC use, low total efficiency persists. For the most part, there is tremendous potential for improving on energy consumption of fan systems. Variable Frequency Drive – A Variable Frequency Drive (VFD) is designed to adjust the speed of an electric motor based on load. The bottom line, the type of fan systems, as well as size, plays a key role in overall performance. Typically, centrifugal fan systems in casing offer an efficiency slightly higher than fans without casing.
