Hub Room AC Switched off

Pre Scenario

20 Hub rooms

24x7 Air conditioning provided

Switches designed to operate in temperature upto 42°C

Switches not required to be

accessed after office hours

Post Implementation

Switching off of hub room AC s

during night & holidays

Innovative Project Auto Tube Cleaning System

Balls injected through condenser inlet, these balls descale the tubes

Impurities collected are discarded through condenser outlet

Innovative Project Auto Tube Cleaning System

Pre Project Scenario

With usage of water cooled

chillers there is fouling inside the

condenser tubes

Resulting in higher kW/ TR

Manual cleaning is difficult &

requires shut down of approx. 24

hours

Post implementation

ATCS is installed as a retrofit on

old chiller & it’s an integral part of

the chiller

Chiller efficiency is maintained

Investment

Projects

Electronically Commutated (EC) motors for AHUs

Features:-

• Low losses & hence 40% less input power to deliver same CFM

• Permits part load operations even at 10%

• Less noise & Elimination of VFD

• Smooth speed control

Tri-rotor water cooled chiller

Features:-

• Full & part load efficiencies are superior to twin rotor screw

technology

• Vastly reduces bearing loads

• Less moving parts – high reliability

• Very low inrush current

• Highly reliable operations even in worst operating conditions

• Specially designed environment friendly R-134a refrigerant

• Capacity control by VFD
