Aerodynamically
designed to prevent the inflow of air is the Berner Air Curtain. The device has strong resistance to air flow
and operates through an air outlet that has a low turbulent air stream.
History
of Air Curtain:
It is
believed that the first Air Curtain was introduced in the year 1904 in North
America but the installation was surprisingly made after 12 years. It became
popular after 1950s and then in the year 1956, the most advanced technology in
air-curtain was introduced by Miniveil. This created a benchmark in the
industry and gave birth to a new company after the name of the patent, Miniveil Ltd.
The company made a renowned name in the industry and sold its first air
curtains in the year 1958 in Canada. After that the trend of using air curtains
was adopted in various sectors across many platforms.
Types
of Air Curtains:
There are
various types of air curtains available today in the market. The most common
types are recirculating and non-recirculating. Recirculating Berner Air Curtains operate in a way
that there is continuous airflow between the discharge grille at one end and
the receiving grille at the other end. The air recirculates and is reused again
and again. In this type, air has to be filtered separately and hence the cost
of maintenance is quite high.
About
Different Types of Cost:
Over that the
initial cost of purchase and the operation cost are also high. In
non-recirculating Berner Air
Curtain, airflow is not continuous rather air pulled into the unit enters
the fan housing and is accelerated there. The accelerated air is then evenly
distributed through the length of the discharge nozzle. The cost of maintenance
is comparatively lower than the recirculating type as the air is not required
to be filtered because there is no re-use of air.
Several
Benefits Offered:
These
benefits mainly include comfort and energy saving. Comfort level is improved by
regulating the temperature and creating a comfortable climate for one and all.
These curtains installed over open doors promote energy savings and reduce the
cost of electricity. These are also used to control insects, climatic
conditions, fumes, and humidity. They also successfully recover stratified
heat, retain heat in ovens, and control air movements within the building and
their popularity is on the go because of its massive advantages.
