Baltic Trail Staff:
65,000 square feet
Savings in Comparison to Regular Store of Same Size:
- Refrigerant Charge: 1,200
- Estimated Total Dollar Savings (%): 4-5%
Our clients, like us, are extremely environmentally conscious, constantly seeking to reduce their carbon footprint. In 2010, Cary Nix and Ken Welter were enlisted to develop a system for a 35,000 square foot store that would reduce the store’s emissions. Managing the entire process of concept to design through construction, they delivered an end result known as a CO2 & Glycol system.
Key elements of the design included:
- direct expansion CO2 cascade system
- electronic expansion valves
- secondary medium temp system
The improvements of a standard system were significant: piping for the medium temp system was reduced by 95% (thereby reducing leak potential), refrigerant charge decreased by 66%, and carbon footprint diminished markedly. In addition, the client requested a second, 55,000 square-foot store be built with a similar system a year later to further test the technology, and continues to encourage us to build upon the technology today.
