Royal Canadian Mint Geothermal Process Cooling System
KGS Group partnered with the Royal Canadian Mint to design and oversee construction of a cutting-edge, open‑loop geothermal cooling system for a new coin‑making process – a first for the Mint. The system uses groundwater’s stable temperature to cool equipment, replacing energy‑intensive chillers and cooling towers, nearly eliminating greenhouse gas emissions associated with conventional cooling.
Cooling now relies on a single pump and as the water absorbs heat from the equipment, heat pumps capture that free energy to warm the building through space heaters and ventilation systems. The conditioned water is re‑injected to the underground source, providing thermal balance and long service life.
KGS delivered an integrated design, controls coordination and construction oversight to bring the system online safely, with minimal disruption to operations. While this project significantly reduced the Mint’s energy use, the success here is the reduced environmental impact it will have for years to come.
