LF-Hy-1 LF-Hy-1-DV - HANSA Klima

Airscreen Devices for Fresh Produce Outlets
You care for your fresh produce and present
it to your customers following the regulations.
We support you with our airscreen solutions
LF-Hy-1 und LF-Hy-1-DV.
Pioneering airscreen devices for fresh produce
outlets, we significantly influenced the DIN
10505 and continuously improve our systems.
Since decades, we offer inexpensive devices
meeting all regulations and optimized for low
energy consumption.
• efficient technology
• low energy consumption
• customizable
• complies to DIN 10505
• perfect hygiene
Quality of air means quality of life [and food]
LF-Hy-1
LF-Hy-1-DV
HANSA aircreen devices make use of the Coanda effect, guiding
the airflow along the inside of the glass panel. This way, your
fresh produce will stay untainted while your customers not even
notice the air screen.
As a further advantage, the HANSA system requires less airflow
than any other solution, leading to reduced energy consumption,
and therefore keeps down costs.
We are exclusively using recirculating air since usually no air handling
except filtering is needed. Of course, if necessary the LF-HY-
1-DV can be seamlessly integrated in your refrigerating plant (heat
exchanger, thermostat, and three valves included).
A HEPA filter ensures sterile air, supported by a prefilter to expand
its durability.
On top of everything:
Our devices are engineered and made in Germany. For your safety.

The HANSA system:
Our system requires a rig slot size of 3 mm and
an airflow velocity of 6 m/s. It immediately follows
a volume flow
Technical Data
V L = 0,003 m x 1 m x 6 m/s
per meter to keep up the airscreen. To maintain
overpressure required by the regulations, an additional
volume flow
V O = V L / 2.
is necessary. Seperating the volume flows accordingly
is done by ducting.
We find for different counter lengths:
