In the riser heat-exchanger system, all the water for each tier of units passes through each unit twice. Both the copper supply and return risers are expanded into a single stack of aluminum fins in each Whalen unit. Published capacities are based on the average water temperature for the tier, which is also the average water temperature for each unit in the tier. Good engineering practice usually dictates that the average chilled water temperature be in the range of 46 degrees F to 50 degrees F. |

The
operation of the Whalen system is not just a theory. It has been operating
successfully in thousands of installations worldwide for more than three
decades. The riser heat-exchanger is still a new concept to many people.
What follows is an explanation of how this unique system works. As with
any new and unfamiliar idea, there may be questions. A consultation
with our engineers is always welcomed.
