Radiant floor warming in a commercial application. [Click on pictures to enlarge]
This is a 5000 SqFt Commercial freezer [10 Degrees below
zero] in the Baldor Foods Corp. facility located in Hunts Point Market, Bronx
NY. The whole facility is a 250,000 SqFt building maintained at 45 to 50 degrees
F [24 hours a day - 7 days a week]. The glycol radiant subfloor warming system maintains 50
degrees under the 6" insulation barrier, which is under the 8"
concrete freezer floor. This prevents the earth sub-base below everything from freezing and then heaving the floor, resulting
in a damaged and inoperable surface for the fork
lifts and electric pallet jacks to ride on. An inoperable fork lift/pallet jack surface puts the
freezer out of commission, which is a big "No! no!" for this type of operation. The subfloor temperature is maintained by an AO Smith 30
gallon electric hot water tank piped to a glycol heat exchanger. It
doesn't take much to maintain high mass temperature once the high mass area
reaches the target operating temperature. Warm and cozy stuff, literally. |
