The Viessmann AirflowPLUS AH2A series air handlers
are to be used in conjunction with Viessmann boilers.
The automatic adjustments are made in heating as well
as cooling. This minimizes selecting an oversized heating
appliance just to accommodate the cooling load.
The Viessmann AirflowPLUS AH2A series is always the
right size.
Cabinet
All cabinets have a tough, durable powder coat finish
on satin coat 20 gauge steel.
Heating coils
All heating coils are copper and assembled using no lead
solder. All coils and internal piping conform to ASTM
B-68, B-88 and/or B-743 standards.
High density aluminum fins provide maximum heat
transfer for small coil surface.
Fan and motor
The ECM fan is a wide body dynamically balanced for
extra quiet operation. Multi-directional sleeve bearing
motors allow mounting in any direction for maximum
installation flexibility.
Circulating pump
The internal circulating pump is matched for maximum
performance. All Airflow PLUS air handlers come with
internally mounted pumps for ease of installation.
Check valve
A check valve is built into the circulator to protect against
backflow of water.
