4.2.2
Compressor
The compressor features a fully hermetic design in approved leading scroll tech-
nology (fig. left). Evaporator and condenser are designed as soldered stainless
steel plate packs with reverse flow circuits, according to state-of-the-art develop-
ment, tailored to the new non-flammable safety refrigerants that will be required by
law in the future. In combination with ester oil (biodegradable), this guarantees op-
timum lubrication conditions, low friction losses and therefore the highest possible
life expectancy for the compressor according to the latest industrial research find-
ings.
The cooling circuit is designed in accordance with the relevant safety regulations.
Manufacturing quality is carried out based on ISO 9000ff, supplemented by an au-
tomated computer-monitored quality test (pressure stress and helium leak test) in
addition to inspection of all parameters in a subsequent trial run.
4.3
Electrical equipment
The electrical connections are made via the internal terminal (on the construction
profile). The implementation of the electrical cable is carried by the rear wall (with
the strain relief).
The internal terminal connects the entire sensor, all queries, all relay outputs, digi-
tal circuit, the compressor and the electrical heating element. The WATERKOTTE
WWPR-controller is supplied with a control panel mounted on the 24 VAC trans-
former.
An integrated web interface is available for remote monitoring via the Internet.
4.3.1
Electrical resistance heating
Located in the heating flow, power 6 kW. Used to support initial heating in the
winter and during the standby function; automatic or independent control via the
built-in mechanical thermostats.
4.3.2
Domestic hot water heating system
Consisting of: heating circulation pump (speed-controlled / energy class A), air
separator with automat. air diverter, connections for heating flow and return are fit-
ted externally to facilitate installation in the rear panel frame.
4.3.3
Natural cooling
The components of the natural cooling are factory fitted.
4.3.4
Heat source
Consisting of: heating circulation pump speed-controlled / energy class A, con-
nections for heating flow and return are fitted externally to facilitate installation in
the rear panel frame.
