A large global retailer wanted to open a high-efficiency store to demonstrate it could operate in a way that saves energy, lowers utility costs and reduces emissions while providing a great shopping experience for its customers. A key consideration for the new store’s design was implementation of a cooling system that would help reduce energy costs and usage.
To meet the retailer’s need for a more energy efficient cooling system, SPX Cooling Technologies supplied Marley® NC Class factory-assembled towers. Classified as “evaporative cooling towers,” they use the evaporation of a small volume of the recirculated water within the system to remove heat.
The towers’ design enables them to consume less water, minimize water treatment costs and use less energy. Manufactured with 30% pre-consumer recycled content, they can also be recycled at the end of their lifecycle — further helping the retailer to meet its goals of establishing environmentally friendly, sustainable practices.
Evaporative Cooling Removes the Heat
Evaporative cooling is considered an environmentally friendly process because it uses naturally replenished water to enhance cooling. The technology used works much like the cooling effect felt when air blows across damp skin. The water evaporating from a person’s skin removes some of the body’s heat; the person feels cooler as a result. This same process allows evaporative cooling equipment to cool below the ambient dry air temperature and is a long-term renewable process as long as water is available.
Maximum Cooling, Minimum Energy Use
The Marley evaporative cooling towers’ gravity-flow water distribution and efficient mechanical drive systems work together to offer maximum cooling with minimum power use. They are more efficient than chiller systems because they can provide a lower condensing temperature, which directly equates to lower energy consumption.
What's Next
SPX Cooling Technologies is continuing to work with this retailer as well as other customers to achieve greater cooling efficiencies throughout their facilities. By custom engineering cooling systems, SPX Cooling Technologies is able to develop solutions that meet specific customer objectives and needs.
