Design and Installation of Control and Automation Panel System for AHU Plant at Ktex Nonwovens Pvt Ltd, Jamnagar by S A Automation Pvt Ltd, Ahmedabad



1.Introduction:
S A Automation Pvt Ltd takes pride in its recent project, the design and installation of a cutting-edge Control and Automation Panel System for the Air Handling Unit (AHU) Plant at Ktex Nonwovens Pvt Ltd in Jamnagar.

2.Total Load Calculation:
The project began with a meticulous calculation of the total load, which approximates to 1900 KW. This includes 1433 KW for working, 43 KW for standby, and provisions for future expansion amounting to 467 KW.

3.Air-Cooled Chiller Integration:
The system incorporates three air-cooled chillers with a total capacity of 456 KW, along with provisions for an additional chiller in the future. Each chiller is equipped with a 630A MCCB (Molded Case Circuit Breaker) for optimal control and safety.

4.Primary Pump System:
The primary pump system, with an 11 KW capacity, utilizes a Mitsubishi VFD (Variable Frequency Drive) FR-CS84-230-60. Additionally, a bypass star-delta starter ensures smooth operation.

5.Secondary Pump Systems:
The secondary pump systems, catering to CHW coil air-washer and AHU panel room, are designed with 22.0 KW and 3.75 KW capacities, respectively. Mitsubishi VFDs FR-E840-0380EPB-60 and FR-CS84-080-60, along with bypass DOL starters, provide precise control.

6.Specialized Secondary Pump System:
A specialized secondary pump system with 5.5 KW capacity serves PHE and a 3-way motorized valve. The logic control ensures modulation based on temperature signals received from the secondary side of PHE. The system includes a Mitsubishi VFD and bypass DOL starter.

7.Uniform Interface for Control:
Each VFD is equipped with a user-friendly interface, featuring start and stop buttons, fault lamps, speed set potentiometer, and a speed DPM meter. A selection switch for VFD and starter enhances operational flexibility.

8.Main ACB for Power Distribution:
To ensure seamless power distribution, the system incorporates a robust 4000A ACB (Air Circuit Breaker) with the necessary accessories, ensuring reliability and safety.

9.Monitoring and Metering:
The control panel includes a set of RYB lamps and an energy meter with three CTs (Current Transformers) for efficient monitoring and energy consumption analysis.

10.Panel Enclosures by Rittal:
A renowned brand, provides the panel enclosures with an approximate width of 800 mm for three units and 1000 mm for three units, ensuring a standardized and durable construction.

11.Auxiliary Components:
Each cabinet is equipped with essential auxiliary components, including fans, filters, door limit switches, tube lights, etc., ensuring a comprehensive and self-contained system.

In conclusion, the successful completion of this project underscores S A Automation Pvt Ltd's commitment to delivering sophisticated and reliable control and automation solutions tailored to the specific needs of industrial plants like Ktex Nonwovens Pvt Ltd in Jamnagar. The integration of advanced technologies and meticulous attention to detail ensures optimal performance and future scalability of the AHU plant.
