Carrier’s WeatherMaker 38TZA with
Puron® provides a completely unique
collection of features which cannot be
matched by any other family of
equipment. The 38TZA family has been
designed as the first air conditioning
system utilizing Carrier’s unique Puron®
refrigerant. The environmentally sound
refrigerant allows you to make a
responsible decision in the protection of
the earth’s ozone layer. Carrier’s
WeatherMaker systems with Puron®
meet the Energy Star® guidelines for
energy efficiency.
AVAILABLE OPTIONS
WeatherArmor™ III System— The
casing steel is galvanized and coated with
a layer of zinc phosphate. A modified
polyester powder coating is then applied
and baked on, providing each unit with
a hard, smooth finish that will last for
many years.
All screws on the cabinet exterior are
SermaGuard™ coated for a long lasting,
rust-resistant, quality appearance.
The coil is protected by an enhanced
WeatherArmor™ heavy duty inlet grille.
Constructed of a coated 12 gage steel wire
grid and with spacing of 3/8 in., the guard
helps to protect the coil from inclement
weather, vandalism, and incidental
damage. It provides protection while not
restricting airflow and maintaining ease of
coil inspection and cleaning.
Puron® Environmentally Friendly
Refrigerant — Is Carrier’s unique
refrigerant designed to help protect the
environment. Puron® is an HFC
refrigerant which does not contain
chlorine that is damaging to the ozone
layer. The most important advantage of
Puron® refrigerant is that it has not been
banned in future air conditioning systems
as the traditional refrigerant, R-22, has
been. Puron® refrigerant is in service in
thousands of systems providing highly
reliable, environmentally sound
performance. For specific R-22 phase out
information see your Carrier distributor.
High Efficiency Performance — Is
delivered through a combination of
features including Carrier’s Puron®
refrigerant, unique scroll compressor, and
advanced heat transfer surfaces. Efficiency
ratings are 12 SEER (Seasonal Energy
