A Breath of Fresh, Cool Air: Cambridge ESC vs. Swamp Coolers


Swamp coolers (evaporative coolers) and Cambridge Air Solutions ESC units both play a significant role in cooling indoor environments, but they differ in their principles of operation and the benefits they offer. While both aim to provide comfort, the Cambridge Air Solutions ESC unit goes the extra mile in enriching lives through its innovative approach to cooling. Now, let's get into what sets them apart...

Swamp Cooler (Evaporative Cooler): 

  • Principle of Operation: Swamp coolers work by evaporating water to cool the air. They are highly effective in dry, arid climates with low humidity. 
  • Cooling Mechanism: These coolers add moisture to the air, which helps lower the temperature. The cooling effect is achieved through the evaporation process. 
  • Energy Efficiency: Swamp coolers are energy-efficient and use less electricity compared to traditional air conditioners. 
  • Suitable Climate: They are most effective in hot, dry climates with low humidity levels, as the cooling effectiveness decreases as humidity levels rise. 

Cambridge Air Solutions ESC Unit: 

  • Principle of Operation: The Cambridge Air Solutions ESC unit uses an indirect evaporative heat exchanger, wherein cooling is achieved through the evaporative process without adding moisture to the supply air. 
  • Cooling Mechanism: The ESC unit uses a one or two-stage cooling process. In the first (indirect evaporative) stage, air is cooled via the indirect evaporative heat exchanger. In the optional second (direct evaporative) stage, air is cooled as it passes over a saturated evaporative media. 
  • Energy Efficiency: The ESC unit is known for its energy efficiency, offering a significant reduction in energy consumption compared to traditional mechanical cooling systems, especially when the environment it’s installed in is fully optimized with a green state of mind. Read the Eldridge Success Story, a real-world example of how a Texas Warehouse optimized their environment to its fullest potential, saving on energy costs in a typically humid environment. 
  • Suitable Climate: The Cambridge Air Solutions ESC unit is particularly well-suited for arid climates. While both indirect and direct evaporative processes achieve more temperature depression in drier climates, a key benefit of the indirect evaporative process is that temperature depression can be achieved without adding any moisture to a building’s supply air.  

Advantages of the Cambridge Air Solutions ESC Unit: 

Energy Efficiency: Using just water to cool supply air, the ESC unit's energy consumption and ongoing operating costs are low compared to traditional mechanical cooling systems. 

Improved Indoor Air Quality: 100% outside air and optional additional filtration lead to improved indoor air quality by preventing the buildup of dust and contaminants inside a building.
