Energy saving at Princeton University

Princeton University is committed to energy-efficient operations as part of its broader sustainability initiative. As such, its Facilities Organization sought to run the university’s central cooling system more efficiently and economically.

Kelvion’s NT350L met the challenge
A waterside economizer would allow the chillers to be turned off during the cooler months, saving energy and costs. The challenge was to find a product that could meet Princeton’s unique water quality requirements.

Kelvion proposed a NT350 gasketed plate heat exchanger with a higher grade of stainless steel. The performance reliability of the NT series is matched by its flexibility to suit a diverse range of applications. Its optimized plate design comes in a variety of lengths, profile variants, and materials that can be customized to suit nearly every requirement.

Efficiency and performance excellence
The Facilities staff at Princeton care about efficiency and performance. The NT350 performs as a waterside economizer. When the outside ambient conditions reach the desired range, the customer can turn off the chillers, using less electricity and reducing the energy costs.

The heat from the central loop then bypasses the chiller and passes through the heat exchanger via the customer’s cooling towers.

After installing the unit on time, Kelvion followed up with on-site training and support.

The result
The customer commented: “The free cooling heat exchanger has gotten a lot of hours of use and helped us avoid a lot of compression refrigeration cycle energy.”
