SM Inlet Shutters
Photo shows various sizes of SMY motorised inlet shutters
SM inlet shutters arc suitable for use in
the poultry and greenhouse industries as well as traditional
industries. In order to obtain a quick and responsive control
over the fresh-air intake into a house, a SM inlet shutter
can be utilized. Air is sucked into the house structure through
an open SD1 inlet shutter by means of exhaust fans, placed
in the exterior walls of the structure, or by our EMT range
of jet fans utilised to blend fresh-air with internal house
air.
To improve aerodynamic efficiency and reduce pressure losses
the shutter design has been developed in Munters euroemme's
R&D lab. The test chamber has been built according to
ANSI / AMCA 210-85 Figure 15 specifications.
Construction details and airtightness have been verified by
personnel of the BESS Lab at the Agricultural Engineering
Dept, University of Illinois - USA.
SMT, SMC, SMA shutter options
SMT Version - Motorised. The inlet shutter is opened by
means of a strong and durable drive-motor which opens the
louvers of the shutter via a re
duction gearbox. The limit position, open or closed is controlled
by an electromechanical limit switch, to ensure a fully open
aperture or a completely sealed and closed shutter. This allows
trouble free automation of the air-inlet requirement process
via a specialized climate controller.
SMA Version - Manual Operation
 This
inlet shutter does not come equipped with a drive motor for
the function of opening and closing the shutter. The process
of opening and closing the shutter must be done manually.
SMC Version - Retrofit Kit
The SMC version has been designed specifically to be used
as a retrofit exhaust shutter system for existing circulation
fans that need to be converted to exhaust fans. This option
allows the simple coupling of an SMC shutter onto the EMS
series Euroemme circulation fans, transforming them into exhaust
fans. All the models of shutter systems are available in knock-down
form for reduction in shipping volumes.
Equipment
- Housing frame made of strong pre-coated and galvanised
sheet-steel
- Shutters are made of pressed galvanised steel in order
to ensure highest strength
- Shutter bearing and seals made of high resistance acetalic
plastic with UV protection, and are maintenance-free
- Shutter systems have been designed to be matched and
balanced in a size ratio with the Euroemme range of exhaust
fans, for energy and pressure drop efficiency
- SMC shutter systems are specially designed to transformed
circulation fans to exhaust fans
- SMT motorized version allows simplicity with automation
of ventilation inlet requirements
- Shutter opening is not affected by the weight of dust
deposited on the shutter blades
- Simple and easy installation
- Each motor and shutter system is individually tested
for 100% quality control and performance
