AAP Fluid and Dry Coolers
What is a Dry Cooler?
Dry coolers are utilized for the cooling of processing liquids, generally pure or brine water, particularly in refrigeration applications, air-conditioning or industrial processes such as free-cooling and the cooling of liquids that circulate inside industrial moulding dies.
The coolers are so called “dry” since they utilize air as a secondary fluid. Compared to solutions that function with water, such as cooling towers, air avoids the problems resulting from the formation of incrustations.
What is a Fluid Cooler?
Fluid coolers have no compressors and use only the temperature difference between the air and the fluid to remove heat from the fluid. This is a very economical transfer of energy. They are an excellent addition to any geothermal HVAC system as they can help reduce the required well field size. Our market is a cooling dominant market. As a result, in many aging geothermal systems the ground temperatures can rise over time. One economical solution to this problem is the addition of an air cooled fluid cooler to alleviate the heat from the system.
What You Should Know When Purchasing a Fluid Cooler:
Fluid coolers are sized on GPM flow through the cooler not Btuh. In a geothermal application, the simplest way is to have full system flow through the fluid cooler at all times and operate the fans when outdoor temps are beneficial. The key to this solution is to have a very low pressure drop to prevent the need to upsize the system pumps.
