The science faculty at one of Europe's leading research universities faced an urgent issue when their existing chiller, which was over a decade old, suddenly failed. With nearly 3,000 students and 400 teaching staff relying on the lab, it was crucial to quickly secure a reliable temperature control solution.


Facing budget constraints, the university's HVAC consultant approached Trane Rental for an urgent rental unit. Trane Rental responded swiftly, delivering a full turnkey emergency solution within 48 hours.

The only delay encountered was caused by the time it took the university to prepare the site where the new rental unit was being installed. The ground was very uneven so the university maintenance staff had to quickly construct a wooden platform where the chiller unit and buffer tank could be placed.

The local Trane Rental team selected a Conquest chiller for its compact and low-profile design, perfectly suited for the available space onsite. Alongside the chiller, a 1,000-liter buffer tank was installed to ensure the required cooling. This solution offered a cooling capacity of 100 kW and a 7°C set point.

The Conquest range by Trane is optimized for R454B low GWP refrigerant and high seasonal efficiency. Designed to minimize operating noise, the Conquest chiller maintains its efficiency and compact footprint while ensuring quieter levels which is critical in the sensitive campus environment.


Overall, Trane Rental's swift response and the reliable performance of the Conquest chiller provided the university with a much-needed temperature control solution, overcoming budget limitations and delivering efficient cooling for the science faculty's lab needing to ensure low temperatures for processes taking place in their clean rooms.

Originally rented for one year, the university extended the rental period, now in its third year, and continues to benefit from Trane Rental Services reliable solution.
