General Manual 04/2007
SUGGESTED SPECIFICATIONS FOR VENTILATOR MODEL DD
Exhaust Ventilator to be SOUTHERN ENGINEERING SYSTEMS by Duke Mfg Co., model DD,
Type I, UL Listed, and in compliance with NFPA Bulletin 96. Ventilator shall be high velocity, low
volume, wash type and have a nominal 95% grease extraction efficiency certified by an independent
testing laboratory.
Canopy, constructed of 18 gauge stainless steel (where exposed) with bottom perimeter edges gutter
less. Weld extraction chamber, plenum, and external seams and joints to form a liquid tight construction.
Polish stainless steel to a #3 finish.
Exhaust plenum Extraction Chamber to be single inlet, same material as canopy, full length of section
at the back. Furnish water wash manifold consisting of a series of spray nozzles installed within
chamber. Manifold to be positioned within plenum area out of air-stream to minimize nozzle clogging.
Bottom of exhaust plenum to be formed into a pitched trough to allow laminar flow, during wash cycle,
to drain pipe connection.
Water Wash System to serve the dual purpose of daily cleaning and fire control. The wash cycle shall
be initiated when the stop-wash button on the control cabinet (required with each hood system) is
depressed. Internal cleaning will be achieved by means of 110° - 160°F water mixed automatically with
injected detergent. In the event the fire control system is activated, the system shall supply a continuous
fire quenching spray. Fire quench shall continue to operate until the reset button is pushed. Pressing the
start button will restart the fan system
Install hinged, motorized Fire Damper full length at air inlet of ventilator. Damper opens when
ventilator is in normal operation, acting as an extracting baffle, and closes when ventilator is turned off
to allow thorough cleansing of extraction chamber interior. Damper automatically closes, sealing
interior of ventilator from fire when thermostat senses 325°F.
Furnish Duct Collar, fully welded, complete with fire detection thermostat, in top of canopy within
exhaust plenum area. Duct collar size based on an average 1800 FPM air velocity.
Integral Make-Up Air shall NOT be furnished.
Unit furnished with 1-5/8” OD stainless steel tubing leg with stainless steel adjustable bullet feet or
necessary channel Support framework for setting unit on floor. Unit must be secured to adjacent
equipment by applicable trades.
Canopy shall be UL Listed and NSF approved. All equipment built in an ISO 9001:2000
approved manufacturing facility

To satisfy most codes, allow a minimum of 6” canopy overhang on all exposed sides of cooking equipment.
However, more overhang should be considered for demanding equipment.

Item Number: ____________
DOWN DRAFT STYLE
WATER WASH VENTILATOR
SOUTHERN ENGINEERING SYSTEMS
SOUTHERN ENGINEERING SYSTEMS Model DD, a Type I, Hi-Velocity, Down Draft Style Water
Wash Ventilator for use over low cooking equipment where a pass-over shelf is desired.
The DD is state-of-the-art in kitchen ventilation. The Southern Engineering Wash design utilizes
centrifugal grease extraction, automatic self-cleaning, and a built-in water barrier for duct and plenum
protection in a fire mode. A normally closed damper prevents the loss of conditioned air during off
hours, and the latest in microprocessor controls for programming hood functions is an optional
enhancement. This ventilator is 95% grease efficient with third party accreditations.
This design is specified where no make-up air is required.
