Two YORK® Chillers will Save University $200,000 Annually

Stimulus funding used to replace chillers with new high-efficiency units

With a growing campus and numerous advanced research facilities, the University of Texas Arlington (UT Arlington) realized the importance of installing more reliable and dependable chillers.

UT Arlington has commissioned two new high-efficiency chillers that will serve the main campus cooling loop and provide annual energy savings of nearly $200,000. The chiller replacement project is one of six major projects on the UT Arlington campus funded by the Texas State Energy Conservation Office (SECO).

The University opted to replace two 3,000 TR chillers, which were charged with HCFC-22 refrigerant with two new 3,000 TR, high efficiency, YORK model YK-EP centrifugal chillers. The new chillers are charged with HFC-134a refrigerant, which has zero ozone-depletion potential and no phase-out date.

The YK-EP chillers feature compressor drivelines with industrial-grade open motors and this means less downtime – something the campus can’t afford with their advanced research facilities. If a motor failure occurs, the chiller can be brought back online mush faster and at a reduced when comparing with chillers that utilize hermetic motors.

Funding the Replacement
TDIndustries, the largest mechanical contractor in north and southwest Texas, helped secure funding for the project from SECO, targeting money that is designated for state projects that meet specific payback criteria.

UT Arlington and TDIndustries entered into a performance contract with Johnson Controls to cover the remaining balance. The savings for the entire project are projected to be over $1.1 million a year.
