Why VFDs are required for Distillery

Energy efficiency Improved process control Reduce maintenance Where does energy efficiency come from? Our process requirements are dynamic and

not fixed depending upon change in production quantity and quality. The only possible control methods for fixed

speed solutions are Throttling, Bypass control, On/Off control or the upgrade with a VFD solution to match

the requirements and achieve energy efficiency.

What is 3c3 coating?

15 | Corporate presentation, January 2015

Benefits of Conformal coating

Withstand harsh environments e.g. aggressive gasses

Protects against environmental pollution, moisture and bagasse dust

No premature failure of Drives due to the harsh environment.

Saves money- less down time

Should fulfil IEC721-3-3 Class 3C3 compared to 3C2 uncoated.

Intelligent Heat Management…Back Channel Cooling

Ducted back-channel passes cooling air over heat sink only.

85% of the heat generated is removed by the heat sink fan through back channel.

Appreciable reduction in operational & ownership costs

Approximately 20-35% heat loss difference is observed with Drives with advanced technology and standard drives.

Back Channel cooling with heat pipe technology Unique heat pipes on heat sink

further improve heat management. 90% of heat losses are

exhausted directly outside of the enclosure Dramatically reduces

temperature rise Reduces contamination of the

electronic components. High Power Density: Highest

possible power output for the physical dimensions of the drive by maximum use of silicon capacity, using cutting-edge technology in thermal management
