Price Chilled Sails couple the radiant cooling and heating effects of standard radiant panels with a convective component for increased performance. Their unique shape gives them more surface area than a traditional radiant panel, increasing their radiant capacity and still achieving the high comfort of radiant systems.

Performance Data

Performance Notes:1. TRoom - MWT is the difference in temperature between the Room air temperature and the average water temperature. The average water temperature is calculated as follows (LWT + EWT)/2. Units are °F.2. Chilled water flow rate is in USGPM.3. Capacity is in BTU per hour. 4. Capacity is based on panel being installed with no suspended false ceiling.5. Capacity is based on occupation density of 50%. Occupation density refers to percentage of ceiling covered by chilled panels. Contact Price Application Engineering for occupation densities other than 50%.
