MODIS 2
The unique structural design based on the modular system
provides the customer with the possibility of selecting
a delivery of the hood disassembled without a branch,
disassembled with a branch (the hood assembled on-site
whether on a self-help basis or by the manufacturer), or
delivery of the hood assembled. To create a longer unit, they
can be assembled side-to-side, or to create the central unit
above the cooking unit, they can be suspended back-to-back.
The MODIS 2 hoods provide an effective exhaust with filtration
of effluent air above the cooking facilities, such as deep fryers,
grill plates, frying pans, and other facilities without an increased
steam generation. Inner partitions, front and side walls of the
MODIS 2 hoods are made of ČSN 17240 (AISI 304) stainless
steel sheet. Filtration of exhaust air is ensured by coffered fat
filters with dimensions of 400 x 400 mm from a multilayer
expanded metal. The hoods are deliver
ed with type dimensions
according to the table, the hoods with atypical dimensions can
be delivered custom-built in the specified range.
The built-in fluorescent lighting (T5 with more economic
operation) is standard part of the hood, having ingress
protection IP 54, thermal resistance up to 60 °C. A terminal
board for lighting connection is located on an upper surface of
the hood.
For flow and pressure losses of the fat filters, see the
dimensioning chart. A residual space between the fat filters is
covered with gap-filling plates. The exhaust branches for
HVAC distributions are not part of the hood, they can be
optionally ordered additionally with a circular or
a rectangular section, with location from above as standard,
see the dimensional chart.
The hoods are provided with holes for suspension. They are
exclusively anchored to a ceiling structure using M8 thread
bars. A plasterboard cover of area above the hood can
alternatively be installed.
RD5 Automatic Control of Operation
I
f ordered, the MODIS 2 hoods can be equipped with the
complete digital control system of operation ensuring the
economic ventilation operation depending on momentary heat
production of cooking facilities and thus preventing uneconomic
run of fans at time when no cooking takes place or at
a reduced thermal load.
The basic principle of automatic control is temperature
sensing in areas above cooking facilities and in the kitchen
area. Unless temperatures are different, the minimum speed
of fans is switched on to ensure the basic air exchange within
the kitchen and operation of gas appliances is enabled. When
a temperature difference between temperature sensors
increases, the exhaust fan as well as the supply fan
automatically switch on to a higher output. When
a temperature difference continues to increase, speed of both
fans continuously increases up to the maximum output.
When this difference decreases, output is automatically
decreased or the basic minimum air exchange is set.
