INNOVATION

Innovation – POC electrostatic filters for split

AC for air filtration

Innovation – Installation VRV system on 4th floor for employees

working in night shift and on holidays to avoid operation of chiller.

Also to have back up to 182 Tr chiller

Innovation – Combination of primary-secondary flow and variable

flow pumps

To overcome the

challenge of

running one

chiller with

variable flow

system and other

with primary –

secondary flow

system piping

system is so

design to cater

Utilization of waste material as Fuel

Projects- No financial investment

Projects- No investment

Fortnightly wet servicing of chillers to enhance

the efficiency
