The heating –
continuous and wear-free
Temperature
The high temperature accuracy in time, as
well as in space is ensured by a continuously
running fan. If required, the speed can be
reduced, such as, for example to avoid
drying of cultures. Coasting of temperature
is almost avoided due to the low mass of
the electric resistance heater. The heater is
arranged directly in front of the recirculating
air fan. The continuous and contactless
control by means of a solid state relay
allows an extremely direct and precise
control. The advantage: High temperature
accuracy and minimum wear.
The standard execution includes an
air-cooled refrigerating machine, which, in
some appliances, is working with natural
refrigerants. The compressor is running
quietly and almost vibration-free. The
efficiency of the heat exchanger is optimal.
The entire cooling circuit is working with
energy-saving solenoid valve-bypass techno-
logy ensuring that the compressor will only
be disconnected, if cooling capacity had
not been required for a longer period. The
result: Reliability, high operating safety and
durability.
The cooling –
energy-saving and powerful
Optionally, water-cooled compressors can
transfer the waste heat directly to a water
chiller of the customer to avoid unnecessary
heating of the installation place. If only a
restricted temperature and humidity range
is required, a direct cooling by means of
brine can be effected instead of the
refrigerating machine.
