Key Engineering Interventions:  

• Fuel System & Boilers Retrofit: 

  • Fuel Conversion: Transitioned from Diesel (Solar) to LPG to reduce operational costs and emissions.

  •  Efficiency Upgrades: Replacement of burners, installation of an underground storage tank with an electric vaporizer, and implementation of advanced thermal insulation (Ceramic Fibers) to accelerate warm-up times.

  • Heat Recovery: Activation of Economizer systems to utilize exhaust heat for feedwater heating and recovery of condensate return (~100°C) to minimize water and chemical usage.

• Compressed Air System Optimization: 

  • Network Upgrade: Replaced scattered piping with a unified Aluminum Manifold System (4-inch) to eliminate pressure drops (1.0-1.5 bar). 

  • Intelligent Control: Implemented a Central Control System (E-Control) to synchronize compressors, significantly reducing energy waste during "Unloaded" idle times. 

  •  Dryer Efficiency: Upgraded desiccant dryers from fixed-timer operation to Dew Point Dependent Control (DDPC), saving 18-22% of energy by eliminating unnecessary "purge air" consumption.

  • HVAC & Cooling Strategy:

    •  Load Management: Conducted detailed performance gap analysis to balance loads across Air Handling Units (AHUs) and prevent mechanical over-stress.

    • Thermal Energy Storage (TES): Proposed a 150 m³ thermal storage well ("Ice Well") to produce chilled water during off-peak hours (night) for use during peak daytime loads.

    • Capacity Enhancement: Recommended adding a backup chiller to improve the Coefficient of Performance (COP) and ensure system redundancy.
