AIR SOURCE MODELS
APPLICATIONS:
The air source models of the gas
absorption heat pump can be used
for hydronic heating and cooling
applications. The IVS-095-A model is
for heating only, and the IVS-095-AR
is heating/cooling reversible.
Hydronic Cooling Capacities:
(IVS-095-AR Model)
Hydronic Heating Efficiencies:
(IVS-095-A Model)
