Variable Frequency Drive A Variable Frequency Drive (VFD) is an instrument used to control and regulate the speed and torque of an appliance through the variance of speed and voltage. VFDs are used in a variety of machinery ranging from ...

In chemical terms, a hydrocarbon is a naturally occurring basic compound of carbon and hydrogen, and is typically to be found in large crude oil concentrations. The non-toxic hydrocarbons are now widely used as a modern refrigerant, being an eco¬-friendly ...

A variable frequency drive is a type of controller that drives electric motors by adjusting the voltage and frequency. This frequency is directly linked to the motor’s speed, so the quicker the frequency, the quicker the speed. Some applications don’t ...

All About the Refrigerant Gas R600a The refrigerant gas isobutane is also known as methylpropane and more commonly as R600a. Its molecular formula is C4H10 and it is the simplest alkane (saturated hydrocarbon) to have a tertiary carbon (three carbon ...

The commercial refrigeration process can be quite complicated. Indeed, the technologies involved have dramatically advanced during the past few decades. While a portion of this momentum is centred around higher levels of efficiency, the need to reduce hydrocarbons within the ...

Hydrocarbons are used in compressors Hydrocarbons are a great oil-less and energy efficient solution to compression motor systems. Where it’s been used in Europe and parts of South Africa, R290 and R60 cooling systems have reportedly used a fraction of ...

Variable Frequency Drive If you are running any kind of operation which involves electric motors large or small, it is likely you have already heard of the mysterious variable frequency drive. If you haven’t, it is high time you get ...

A refrigerator is by far one of the most remarkable inventions in the history of humanity. The process of refrigeration has not just improved the longevity of our food items, but has facilitated storage, preservation and availability of food throughout ...

A hydrocarbon is any chemical compound that is made of just carbon atoms and hydrogen atoms. They are obtained from crude oil by fractional distillation and can be classified in different groups. The four general classes of hydrocarbons are alkanes, ...

Variable frequency drive technology (VFD) has been developed to allow speed and torque control of an AC motor. This is achieved by connecting a variable frequency controller to an AC motor. Three phase induction motors are the most common though ...
