Passive Heat Transfer
Circulation line heat exchangers
The circulation line heat exchangers are the perfect solution for:
•
Heating and/or thawing cold or frozen ground.
•
Frost prevention.
•
Concrete curing and heating in subzero environments.
The DRYAIR system can be applied to all types of concrete applications. Circulation line
heat exchangers can be secured directly against the surface of the concrete or concrete forms.
Alternately, an expendable circulation line can be incorporated into the concrete structure
during the pour. Thus the slab floor can continue being heated, to provide radiant floor heat
during construction.
Hose reel
The DRYAIR hose reel is capable of holding over 6000 ft. of 3/4" I.D. circulation line heat
exchangers. The reel can be transported by common carrier, or slings can be used for lifting.
The hose reel is forklift accessible from all four sides.
The reel is ideal for on-site applications:
•
A "unique" auto-feed system eliminates the need for a second person at the reel when
laying out hose.
•
The independent modular design lets you store the hose reel at a secure location on or off
the job site when not in use. The independent modular hose reel also allows deployment
of hose at more than one job site.
•
The reel can be used to store or deploy other distribution lines used in DRYAIR portable
heating applications.
•
The reel can also be secured onto its own transport trailer. The trailer's "no-clog" opening
directly under the hose reel prevents mud build up. A "no slip" working deck promotes
safe, convenient and dry hose reel operation.
Accessories
Trailers
Several different models are available depending on the required applications. Single or
tandem axle trailers are available depending on the size of water heater module and the
accessories requiring transportation.
Mixing/booster pump
The multifunctional mixing/booster ensures maximum flexibility in the use of the DRYAIR
system.
•
Tempering mode supplies lower temperature fluid for concrete cure and radiant floor heat
applications eliminating the need to reduce the water heater operating temperatures below
safe operating ranges.
•
When operating in booster mode, the system can increase flow rates or function as a
pumping station to increase pumping distances.
•
The mixing/booster also allows for dual-temperature control. High temperature fluid can
be provided to portable heat exchangers, along with a lower temperature fluid for concrete
cure and radiant floor heat applications.
Insulated line jackets
Insulated circulation line jackets are also available. These insulated jackets will prevent
exposed circulation line heat loss in extreme subzero conditions.
