2.1 32 Series – commercial applications
Benefits of the 32 Series for commercial applications
u   T he 32 Series is designed specifically for commercial use.
A flow rate of 32 litres per minute at a 25°C temperature
rise makes the 32 Series a true commercial hot water
system.
u   The 32 Series has a coated copper heat exchanger to
prevent corrosion and deterioration. The internal copper
piping is 25% thicker than standard domestic models for
extra durability.
u   Depending on the water volume required, the Bosch 32
models (KM3211WHNG/LP) can be installed as a single
unit, manifold (see chapter 2.3) or are delivered as part of
a Bosch Professional Pack, a pre-assembled system
including a 315 litre stainless steel storage tank (see
chapter 2.2).
u   External or internal* installation options make the 32
Series conveniently versatile.
u   Up to 3 optional temperature controllers can be installed
with a Bosch 32 model (KM3211WHNG/LP only): 1 main
controller (RCM3211) and up to 2 sub-controllers
(RCS3211).
u   Additionally, the 32Q model (KM3211WHQNG/LP)
includes a built-in pump and a main controller, which
allows for programmed water re-circulation on a ring main
e.g. for peak usage times. The delivery time of hot water is
reduced as well as unnecessary water usage.
* Internal installations require flueing as per AS 5601 / NZ 5621.
Flue kits are available for 32 Series.
