Kitchen Ventilation Systems

Greenheck offers a wide selection of top quality kitchen hoods,

exhaust fans, make-up air units, variable volume systems, fire

suppression systems and utility distribution systems. These

systems can be designed by using our state-of-the-art Computer

Aided Selection Program (CAPS). This program enables you to

select and configure products as well as view real-time drawings

and create AutoCAD files instantly.

Proximity Hoods

Length from 3 to 16 feet, height from 24 in. to 42 in., width from 23 in. to 36 in.
Available with all filter options. Available with flue bypass. The flue bypass option
directs hot flue gasses behind the filter bank with the benefit of reducing the radiant
heat load in the space and prevents baking grease onto the filters. This option is
appliance specific, please contact factory for design assistance. Plate shelf optional.

Flex-Connect™ Utility Distribution Systems

Flex-Connect Utility Distribution Systems provide flexibility, convenience and safety in commercial cooking operations. Factory built
systems offer a cost effective way to replace contractor built utilities in walls. These systems provide a single point of connection for
gas, electricity, water, and steam. Utility Distribution Systems are available in wall and island styles.

Flexible

The Flex-Connect Utility Distribution System allows for future expansion or relocation
of appliances without expensive modifications. Gas appliance drops are located
every 12 inches, hot and cold water drops every 24 inches to allow for equipment
line-up changes. Electrical service can either be point of use breaker of panel board.
Receptacles are available as an additional option.

Convenient

Modules are available in incremental lengths, expandable to accommodate virtually
any cooking line-up.

Fast

Installation requires only limited trade involvement to bring incoming utility services in
for hook-up.

Kitchen Fan Control Center

Greenheck’s Kitchen Fan Control Center, Model KFCC, is designed to control the
exhaust fans, supply fans and lights for the kitchen ventilation system. The KFCC can
be interlocked with the fire suppression system.

Fire Suppression Systems

The first line of defense against fire in a commercial kitchen is the hood fire protection system. Greenheck has a variety of factory
pre-piped fire protection systems available.

Wet Chemical - Ansul R-102, Ansul Overlapping Coverage,
Amerex KP, Amerex Zone Defense

The Ansul R-102 and Amerex KP Wet Chemical, Fire Suppression System is an
automatic, pre-engineered system, designed to protect ventilating equipment including
hoods, ducts, plenums, filters, and cooking equipment. Once activated, the system
discharges Wet Chemical through all nozzles simultaneously.
Amerex Zone Defense and Ansul Overlapping Coverage offers full flood fire protection
that allows flexibility in equipment placement.

Dual Agent

The Ansul PIRANHA Restaurant Wet Agent Fire Suppression System is a dual­agent, pre-engineered fixed, automatic fire extinguishing system, designed to protect
ventilating equipment including hoods, ducts, plenums, filters, and the cooking
equipment. Once activated, the system discharges Wet Chemical followed by water
through all nozzles simultaneously.

Catalog: Ansul PIRANHA

Variable Volume

Variable Volume systems automatically control the speed of the exhaust (and make-up air if applicable) fan to ensure optimal hood
performance.

Variable Volume

Variable volume kitchen ventilation systems utilize microprocessor controls and operate
solely on demand. The system monitors the cooking operation and adjusts the exhaust,
supply, and rooftop unit fans so when the cooking load is reduced, the fans operate at a
reduced level saving energy. Typically there is a 50% reduction in cost to temper supply air.

Supply Fans and Make Up Air Units

Centrifugal Roof Supply Fans - Models RSF & RSFP

The Centrifugal Roof Supply Fans include filtered and non-filtered belt driven units. These
fans are suitable for non-tempered kitchen make-up air or building supply air. These fans
feature forward curved wheels for high efficiency and low sound. Housing styles include a
straight sided hood (RSF) or a louvered penthouse (RSFP). Capacities range from 650 to
14,300 cfm and up to 2.5 in. wg.

Catalog: Models RSF/RSFP Forward Curved Centrifugal Roof Supply Fan

Models KSFB and KSFD

Models KSFB and KSFD economically supply untempered make-up air where needed.
Kitchen make-up air applications are common and an extended weatherhood option
provides a 10 foot separation between intake and exhaust fan discharge. Airflow volumes
range from 800 to 10,500 cfm

air as part of a total kitchen ventilation system. The make-up air packages are available
with a variety of tempering options for heating and cooling. In addition to basic make-up
air operation, recirculation and variable volume airflow options are available on direct gas
(Model DGX) and indirect gas (Model IGX). Capacities range from 800 to 24,000 cfm with
static pressures up to 2.5 in. wg. See pages 36-38 for more make-up air information.

Exhaust Fans

Several different types of Exhaust Fans are utilized in commercial kitchen applications: Centrifugal Upblast and Sidewall Exhaust
Fans, Utility Fans, and Inline Fans.

Centrifugal Upblast and Sidewall Exhaust Fans - Series C

The Centrifugal Roof Upblast and Sidewall Exhaust Fans include both direct and belt
driven fans with backward inclined centrifugal wheels. These spun aluminum fans are
specifically designed for roof mounted or wall mounted applications. Contaminated or
grease laden exhaust air can be discharged directly upward, away from the roof surface or
discharged out and away from building walls. The fans are suitable for applications such
as range hood or fume hood exhaust. The model CUBE is available in 3 pressure ratings:
standard, HP (high pressure) and XP (extended pressure). A steel version, USGF, is also
available. Capacities range from 80 to 26,000 cfm and up to 5.0 in. wg. UL-762.

Catalogs: •Centrifugal Exhaust Fans (Series C)

•Centrifugal Roof Exhausters (Models G/GB)

Utility Fans - Model SWB

The Utility Fan is belt driven and features a backward inclined centrifugal wheel. This fan is
suitable for ducted exhaust, supply, and return-air applications. Typical applications include
commercial kitchens and fume hoods. Capacities range from 500 to 23,000 cfm and up to

4.0 in. wg. UL-762.

Catalog: Centrifugal Backward Inclined (Model SWB)

Inline Fan, Backward Inclined Wheel - Model TCB

The TCB uses a backward inclined centrifugal wheel for high efficiencies and low sound
levels when used in medium pressure ducted systems. All TCB inline fans are belt driven
with the motor out of the airstream. Optional construction includes the roof upblast model
TCBRU and roof supply model TCBRS. AMCA licensed for Sound and Air Performance.
