How the DRYAIR System Works
The DRYAIR system uses a low-pressure,
open fluid loop distribution system with an
atmospherically vented fluid reservoir. A
hydronic water heater warms the heat transfer
fluid. This heated fluid is pumped through a
distribution system loop, passing through heat
exchangers in remote locations.
Two types of exchangers are available:
•
Portable heat exchangers include a heat
transfer coil, fan and thermostatic
temperature control. The heat transfer
fluid flows through the transfer coil, where
heat is transferred to the air being drawn
through the coil by the fan. The coil is
specially designed for optimum heat
transfer, without adding any moisture or
combustion by-products to the air.
•
Circulation line heat exchangers use
flexible hose with hydraulic-style quick-
couplers for ease in hookup. Heat transfer
occurs by direct contact heat transfer and
radiant heat conduction.
The mixing/booster unit can be utilized to:
•
Provide lower temperature fluid for
concrete cure and radiant floor heat
applications.
•
Provide dual temperature control with a
single fluid circulation system.
•
Boost fluid flow and increase pumping distances.
