Creation of electrical
controls and regulators and the proper practical methods for fault finding and
- As a result of the
universal suspended plug-in system and a variety of standard components from
the refrigeration and air-conditioning technology areas, which are built into
the suspended plug-in panels, all installations, controls and plant systems
used in practice can be operated according to proper practical methods.
- Use of standard controls
and regulators from the industry
- With the use of 2 evaporator
fans equipped with the standard continuously controllable counter heaters
and ventilators for the deep-freeze, standard refrigeration and air-conditioning
areas, various loads can be simulated, whereby field-proven operational conditions
can be recreated.
- The evaporator fans
have been specially developed for the refrigeration/air-conditioning trainer
series DUO 2000 and function in various temperature ranges between +10° C
- A well considered and
proven system for practical training in institutes, trade schools and universities.
- Especially suitable
for use in non-dual school systems.
- Two different power
supply sources are standard.
- Printed cards of unbreakable
- Temperature behaviour
observation of refrigeration and air-conditioning plants with up to 12 variable
- The refrigeration /
air-conditioning trainer series DUO 2000 brings the missing practical aspect
back into training institutions.
- The electrical superstructure
can be safely used by students. Safety wires, sockets and fuse disconnector
transformers are standard components of the refrigeration / air-conditioning
- As a result of well
conceived expansion components, the refrigeration / air-conditioning trainer
series DUO 2000 also covers the most varied training levels of various training
- For example, there
is a dual level cold compressor for temperatures from -5O °C available as
an expansion component for cryogenic freezing experiments (for refrigerants
R-502, R-13 Bl, R-22).
- The corresponding deep-freeze
section is a standard component of the refrigeration / air-conditioning trainer
series DUO 2000.
- For example, control
organs for the various temperature ranges can be constructed by the students
themselves, or they can use already wired switch boxes.
- The modular system
offers optimal price/performance value.
- Very comprehensive
basic equipment, with a cold compressor of an open construction type.
- Standard text English/German.
- Simple to adjust to
requirements because of its clear equipment lists.
