MODEL

HOT WATER COILS

The AQUECOIL is ideal for providing heated air in applications such as residential or commercial

warm air heating, or reheat for humidity control. The

Series has been

engineered to improve upon duct mounted hot water coils that have been used in the industry for

years. Higher efficiency coils provide greater heat output, lower static pressure on the air stream, and

ure drops in the water line. The galvanized steel frame and unit dimensions are

consistent with products already in use to allow for easy replacement of existing coils. That also

FEATURED HIGHLIGHTS

APPLICATION

The AQUECOIL Hot Water Coil A-Series works
in conjunction with any source of hot water
(which can supply enough BTU's to meet your
heating load), such as a Conventional Water
Heater, a Tankless Water Heater, or Boiler, and
an air distribution system. AQUECOIL Hot
Water Coils may be mounted in either the
supply or the return side of the duct system, in
either vertical or horizontal orientation. The
addition of an external air vent is recommended
to assure complete air purging.

• 1/2” OD, .017” wall copper waterways for
improved heat transfer and durability

• Mechanical tube expansion for permanent
bond to fins

• Sweat connections for quick attachment to
water lines

• Up to 500 PSI opera
PSI maximum pressure

• 1" flange on galvanized steel frame

• 3-Year parts warranty

The use of field installed swing check and
isolation valves is strongly recommended.
Heat output can be adjusted to system
requirements by modifying the water flow, air
flow and water temperature. If the hot water
source does not have its own system circulator,
the AQUECOIL Hot Water Coil can be
connected to an AQUECOIL Pump Module,
Models PM-1 or PM-2, to provide the necessary
control functions and specified water flow rates
though the coil.

upon request.

NOTES:

1) All BTUH calculations use 60°F entering air temperature
and 180°F water temperature.

2) Water circulation is handled either by the existing boiler
system or by installing one of the optional pump
modules, depending on application.

3) The last digit of the model number indicates the number
of rows of copper in the coil.

WARRANTY: All Aquecoil Duct Coils offer a limited 3-year parts warranty.
