MESSUNG IS DISTRIBUTOR IN INDIA FOR FUJI ELECTRIC'S VFD DRIVES

Messung Industrial Automation & Controls is proud to be Distributor in India for Fuji Electric’s range of simple and high-performance Variable Frequency Drives (VFDs).

…………………….

THE EXPANDING VFD MARKET

The global VFD market is growing. These drives are emerging as an integral part of several machine markets, both small- and large-scale. They are used in applications ranging from small devices to large compressors.

Globally, VFDs are used across several end-user sectors, including infrastructure, industrial, power generation, oil & gas. Growing emphasis from government organizations to reduce energy consumption to achieve a net zero energy goal is one of the key trends contributing to the growth of the market.

Rapid technological advancements along with proliferation of connected devices in commercial, household, and industrial sectors coupled with rising awareness about the benefits of these drives are encouraging their adoption.

WHAT IS A VARIABLE FREQUENCY DRIVE?

A Variable Frequency Drive (VFD) is a type of adjustable-speed drive used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequency and voltage. Other names for a VFD are variable speed drive, adjustable speed drive, adjustable frequency drive, inverter drive or AC drive.

HOW DOES A VFD WORK?

- First, the converter (usually a diode rectifier) converts three-phase AC power to DC power.

- Next, the DC Bus stores and filters the DC power in a large bank of capacitors.

- Last, the inverter (usually a set of six IGBTs) switches or inverts the DC power in a Pulse Width Modulated (PWM) AC waveform to the motor.

BENEFITS OFVARIABLE FREQUENCY DRIVES?

There are six primary benefits of VFDs:

1. Keeps starting current in control: A VFD has the capability of starting the motor at zero voltage and frequency, which keeps a check on motor winding flexing and heat generation. This helps in extending the motor life.

2. Reduces power line disturbances: Any voltage sag caused in the power line can adversely affect voltage sensitive devices such as proximity switches, sensors, and computers. Using VFDs eliminates voltage sag.

3. Demands lower power on start: Power required to start an ac motor across the line is substantially greater than with a VFD. When industrial customers start these motors during peak hours of electrical consumption, they are likely to be charged with surge prices. However, with VFD demanding lower starting power, the issue can be addressed.

4. Helps in controlling operating speed and acceleration: Applications such as bottling lines that include easy-to-tip product significantly benefit from a gradual increase in power. This allows conveyer belts to smoothly rev up rather than an abrupt jerk to full power. They also allow speed to be remotely adjusted by a controller. Control is speed and acceleration are a big bonus to industries in a production process.

5. Limits and adjusts torque: The drive is capable of limiting and adjusting the amount of torque so the ac motor never surpasses this limit. This protects machinery from damage and protects the process or product.

6. Saves energy and cost: A VFD regulating a pump motor that usually runs less than full speed can cut down energy consumption over a motor running at constant speed for the same period. In addition, it eliminates the need for mechanical drive components, which also helps reduce overall costs.

About AHU

An Air Handling Unit (AHU) regulates and circulates air as part of a heating, ventilating and air-conditioning (HVAC) system. It consists of a blower, heating or cooling elements, filter racks, sound attenuators and dampers. It is usually connected to a ductwork system that distributes the conditioned air through the building and returns it to the AHU.

Sometimes, AHUs discharge and admit air directly to and from the space without ductwork.

With the growing emphasis on energy performance in buildings, and new standards to study and improve energy efficiency, buildings need automation & control systems to achieve high levels of energy efficiency.

HVAC is one area where huge amount of power is consumed, and where plants with energy-optimised design, installation and commissioning are a must. Automation with AHU-specific functions ensures more systems' energy efficiency, operational reliability and availability. Automation also monitors room and outdoor temperatures to reduce cooling energy needs and improve comfort levels.

MESSUNG is an Automation Partner capable of Supplying Solutions to any Project of Air Handling Units and Environment Control Systems.

A Case Study

“Our Customer is a Bengaluru based company involved into manufacturing of Products like Metal Working Tools, Mining, Foundation Drilling cutting Tools, Tungsten carbide wear components etc.. required for Industries like Aerospace, Additive manufacturing, Machine Tool Industry, Energy, Earthworks.”

Basic AHU for Coating Room

The project required Messung’s solution to ensure that the coating room is maintained under 5 Pa Negative pressure with respect to ambient and within the room temperature zone of 21.1 Deg. C to 24.4 Deg. C and RH Zone of 40% to 60%. Since the system is working round the clock, it is necessary to control the system in such a way that minimum power is consumed by the HVAC system.

In addition, in case of any process gas leakage in the coating room, fresh air supply and exhaust to be operated at the it’s full capacity to exhaust the leaked gases promptly.

Messung’s solution

- Messung proposed an AHU System which can maintain acceptable room conditions using 2 stage evaporative cooling or using chilled water cooling coil, depending on the ambient air conditions throughout the day and year.

- Variation of ambient conditions in Bengaluru through the day and year is such that the ambient air conditions can be used to maintain the desired room conditions for much of the time, mainly in cooler nights and winter season.

- Since the plant is working round the clock, Messung decided to make use of favorable ambient conditions to the best possible extent to minimize the power consumption by AHU system.

- Messung divided the variation of ambient air conditions throughout year, into 3 parts:

o Mode -I, where in the ambient condition is hot and dry, where either single stage or 2 stage evaporative cooling can be used to maintain room conditions.

o Mode – II, Monsoon conditions with high RH and not so cold temperature, wherein conventional chilled water cooling coil will be used to cool and de humidify and maintain the designed room conditions

o Mode – III, typically winter conditions, Messung proposed to modulate return air and cold fresh, as well as single stage evaporative cooling to maintain the designed room conditions.

Proposed Control System
