Objective	Challenges
Improved IAQ levels with the below parameters under specified limits & Adhere to ASHRAE/ ISHRAE post COVID *Guidelines* •AQI •PM2.5 •PM10 •CO2 level	•High PM2.5 levels •Maintaining CO2 level increases Particulate count •Existing Air handling Units •Microbial Growth on Cooling Coils
Result	Solutions
•Real Time Monitoring •IAQ Parameters under specified limits •Adhering to Guidelines of ISHRAE/ASHRAE •No reduction in cfm •Seamless integration of Air purification solutions in existing HVAC system	•Real Time Monitoring •Electronic Air Cleaners in TFA and AHU’s •UVGI solutions for AHU’s

OBJECTIVE	CHALLENGES
To control microbial/mold formation on cooling coils of AHU’s in critical processing areas	•Retrofit existing AHUs with UV-C emitter •Most of AHUs were operational 24/7 •Installation to be completed within Shut Down •UV-C Lamp breakage can lead to glass particles/Mercury entering air stream and can cause issues as this was a food processing application
RESULT	SOLUTIONS
•UVGI solutions designed and installed within the short window of work permit given •Ensured Shatter-proof Lamps are installed to address concern on Glass particles entering air stream •Custom designed frames to suit the application	•Installed Shatterproof UV-C Lights on AHUs •Designed Movable frames/Modular solutions to enable AHU maintenance processes
