The Challenge<br />

Ensure manufacturing<br />

workers’ comfort by<br />

supplying 100 % outdoor air<br />

and by exhausting stale air.<br />

Exhaust excessively heated<br />

air from a new machinery<br />

room containing air<br />

compressors and industrial<br />

air dryers.<br />

Design a safe, explosionresistant<br />

ventilation system<br />

for a painting storage room.<br />

Provide a complete kitchen<br />

exhaust and supply system<br />

in the dining area to<br />

accommodate more than<br />

600 employees.<br />

Toyota Motor Manufacturing<br />

de Baja California (TMMBC), Baja<br />

California, Mexico, is Toyota’s<br />

first manufacturing plant in<br />

Mexico. In 2006, the plant began<br />

a major renovation, including<br />

the addition of 81,429 square<br />

feet (7,565 m2) of manufacturing<br />

space to accommodate an<br />

increase in production capacity.<br />

The production area required<br />

ventilating the space by<br />

supplying 100% outside air. Due<br />

to the chemicals and hazardous<br />

materials in the painting storage<br />

room, reliable exhaust equipment<br />

with explosion proof motors and<br />

spark resistant fan wheels were<br />

required.<br />

The additional production<br />

capacity allowed the company to<br />

hire 300 new employees—which<br />

required a renovation project for<br />

a larger kitchen area and dining<br />

room with complete ventilation<br />

and fire suppression systems.<br />

A second machinery room with<br />

several industrial air dryers and<br />

compressors was also added to<br />

the plant and required exhausting<br />

hot air produced by the machines.

<strong>Greenheck</strong>’s Solution<br />

Two <strong>Greenheck</strong> Kitchen<br />

Hoods, Model GHCW<br />

Two Tube Axial Fans,<br />

Model TBI-FS<br />

Five Utility Centrifugal Fans,<br />

Models SWB/SFB<br />

One Ceiling Exhaust Fan,<br />

Model SP<br />

Five Hooded Propeller Roof<br />

Fans, Models RBE<br />

One Make-Up Air Unit,<br />

Model IGX<br />

A total of 16 <strong>Greenheck</strong> air<br />

movement and control units<br />

were carefully sized and selected<br />

to sustain the most favorable<br />

operating environment for the<br />

<strong>Greenheck</strong>’s indirect gas Make-Up Air unit, Model IGX.<br />

The Results<br />

According to ISAR, the<br />

mechanical contractor on this<br />

project, the <strong>Greenheck</strong> makeup<br />

air unit and all <strong>Greenheck</strong><br />

exhaust and supply fans are<br />

operating at 96% of specified<br />

performance. All rooftop<br />

ventilation units have small<br />

footprints making the roof<br />

Toyota plant’s new addition.<br />

<strong>Greenheck</strong> hooded propeller<br />

roof fans, Model RBE-3L42, were<br />

installed to deliver more than<br />

163,000 cfm of fresh outdoor air<br />

for optimal ventilation in the<br />

production area. Because these<br />

fans were delivered with specified<br />

roof curbs, the contractor only<br />

needed to reinforce the roof<br />

surface. In addition, easy access<br />

to fan components will reduce<br />

future maintenance and service<br />

costs. The tube axial fans, Model<br />

TBI-FS, were used to exhaust<br />

the hot air generated by the air<br />

compressors and dryers in the<br />

machinery room. One utility<br />

centrifugal fan with a spark-proof<br />

resistant fan wheel and explosionproof<br />

motor was installed to<br />

safely exhaust fumes from the<br />

paint storage room.<br />

In the expanded kitchen area,<br />

a tempered make-up air unit,<br />

Model IGX, two <strong>Greenheck</strong><br />

kitchen hoods, Model GHCW,<br />

with front supply plenums and<br />

ANSUL R-102 wet chemical<br />

space less crowded — ideal for<br />

maintenance, inspection and<br />

servicing the units. “<strong>Greenheck</strong><br />

certainly provided us with<br />

adequate equipment to satisfy<br />

all our customer needs for this<br />

particular project. We are very<br />

pleased with the performance of<br />

the <strong>Greenheck</strong> fans,” says Javier<br />

One of five hooded propeller fans being set in<br />

place on a roof curb.<br />

fire suppression systems, and<br />

one utility centrifugal fan were<br />

installed to ensure comfortable<br />

indoor air environments for both<br />

food preparers and employee<br />

diners. The remaining utility<br />

centrifugal fans and one ceiling<br />

exhaust fans were installed to<br />

provide bathroom ventilation.<br />

All <strong>Greenheck</strong> ventilation<br />

equipment utilized in this project<br />

is licensed to bear the AMCA Seal<br />

for Sound and Air Performance.<br />

The kitchen ventilation system<br />

has UL-762 certification and also<br />

meets NFPA-96 guidelines.<br />

TMMBC was awarded the Gold<br />

Plant Award for Quality among<br />

all North and South American<br />

automotive manufacturing<br />

plants.<br />
