Easy control via 10” touchscreen
The operation and control of the system and the visualisation of all operating parameters are performed via a
user-friendly touchscreen. All recorded data can be stored on a long-term basis and exported via USB if required.
The weekly or monthly generation of an operating log book takes place fully automatic. Presentation directly
on the display is also possible.
• Economic viability
Double comb stable in the Steinfurt district for
a piglet rearing
The stable with a size of 16 X 25 m2 is a double comb stable. It is conceived for
approx. 1,000 piglets in respectively 8 bays of 125 animals.
The fresh air feed takes place via a feeding passage fan. The exhaust air is fed via a
central exhaust air duct in which the 2 air-air heat exchangers with a performance of each
23 kW are integrated.
Pigs fattening stable with 1,600 places in the
county of Bentheim
The pigs fattening stable with 8 compartments of each 200 places are supplied with via
a trapezoid fan ceiling with fresh air.
Among the 6 exhaust air ducts Ø 920 mm arranged in the central extraction, the two
regulated exhaust air ducts are provided respectively with an air duct silencer. The noise
reduction amounts to 12dB(A).
The following parameters can be
read off in detail from the display

For the central extraction, 4 exhaust air ducts Ø 920 mm are used with fan, which are
controlled per climate computer.
