In the heart of Punjab University, a legacy of engineering excellence hasquietly endured for over five decades. Installed in 1970, Carrier chillersbecame part of one of India’s earliest centralized cooling systems amongthe oldest Carrier chillers ever commissioned in the country. 

For over half a century, these chillers delivered steady, reliable cooling, enabling uninterrupted operations across the academic blocks and the expansive central library covering 93,320 sq. ft. and accommodating six reading halls. - only in library 

Backed by dependable service support, the system remained a symbol ofdurability, performance, and trust for generations

OBJECTIVE

As the university expanded and cooling demands increased, theneed for a modern and efficient solution became essential. PunjabUniversity sought to:

  • Upgrade an HVAC system that had operated for over 50 years
  • Improve energy efficiency and reliability
  • Ensure long‑term performance with minimal disruption
  • Beyond technical performance, the goal was to preserve thelegacy while transitioning into a new era of sustainable campusinfrastructure.

SOLUTION

Carrier replaced the legacy reciprocating units with advanced screw chillers,engineered for:

  • High‑efficiency performance
  • Long operational life
  • Stable cooling under varying loads 

Carrier 30XWV screw chillers with a total installed capacity of 300 tons,ensuring robust, future‑ready cooling for the campus..

This upgrade was driven by Punjab University’s long-standing trust in Carrier:

  • Proven product quality
  • Strong and consistent service capability
  • A partnership built over 55 years of continuous performance

RESULTS

The project reinforced Punjab University's commitment to sustainable,long-term infrastructure. The new Carrier screw chillers delivered:

  • Improved reliability across critical campus areas
  • Enhanced efficiency suited for large educational facilities
  • Optimized temperature control for high-occupancy zones
  • Stronger lifecycle value with modern technology
  • From 1970 to today, the Carrier–Punjab University partnership standsas a testament to durability, innovation, and progress—atransformation that honors the past while powering the future
