2. Who Is Espar?
• Espar is a wholly owned subsidiary of Eberspaecher, representing the North America
heater division established in 1973. Products are offered OE with a nation-wide dealer
network offering aftermarket sales and support of equipment. Eberspaecher is the
largest producer of fuel-operated heaters in the world.
• Espar offers fuel-operated heaters for engine pre-heat & supplemental cabin heat
for a wide variety of vehicles and equipment from automotive, trucks, buses, to large
construction equipment and military equipment.
Use of these heaters
allow engine pre-heat and drivers
to stay warm without prolonged engine
idling. Fuel-operated heaters do not
require any plug in. These operate
with on-board gasoline, diesel, blends,
or bio-diesel and a small amp draw
on the vehicle battery.
Espar makes idle reduction possible!

Why Do Drivers Idle Diesel Engines?
Drivers Idle The Engine:
•To Pre-Heat The Engine and Defrost Before Driving
•To Make Sure Engine Will Start When Needed
•While Waiting in the Cab of Vehicle or Equipment
•To Get Heat in the Bunk While Sleeping

5. Tested and Validated
• ESPAR is listed on the EPA website as an idle reduction solution
• ESPAR earned CARB approval
California Air Resources Board--industry standard for low emissions ULEVII

Why Not Just IdleThe Engine?
Old Habits May Be Hard To Break!
• High Fuel Costs - Idling gives you ZERO mpg
• Increased Maintenance Expense
– One hour of idling puts the same wear on the engine as two hours of driving the
bus, degrades engine oil and reduces the life of the engine oil by 75%*
– Idling damages the engine from carbon deposits on valves and pistons, and
accumulation of water and sulfur in the engine
• Shorter Time Between Engine Rebuilds
• More Tons of Exhaust Pollutants Enter The Air
* FLEETSMART Idling Gets You Nowhere,

7. Solution--
Pull The Plug On Idling
• Plugging In an electric block heater will provide limited heat in the engine
block to help the engine start in cold weather.
• Plugging In does not pre-heat the entire engine and coolant system or
create warm defrost. Drivers regularly idle the bus for heat and defrost
even when using a plug-in system.
• Plugging in costs the school district or municipal government money for
electricity in addition to fuel expense for idling*
*Excel spreadsheet calculator is available to calculate cost of using
electric block heaters compared to fuel-operated heaters

• Blows warm air like your home furnace
• Thermostat / temperature sensor controlled to maintain heat
• Keeps the driver warm WITHOUT idling the main engine
CLEAN WARM EFFICIENT

9. AIRTRONIC D2 HEATER
Work Trucks, Sleepers, Day Cabs, Other Vehicles & Equipment
• Air heaters blow warm air so the main diesel engine can be shut down
• Weighs 7 pounds and the size of a loaf of bread
• Has four-speeds and air circulation mode for operator comfort
• Up to 7,500 BTU of clean comfortable heat
• Medium setting uses only .04 gallons per hour
and about as much voltage as a single marker light
• EPA SmartWay Verified & CARB approved (D2, D4 & D5)
• Built in safety features for worry-free operation

10. Idling Used $6,000 in fuel—
One class 8 truck for one year
The quick and simple formula
Assumptions-
– Idle fuel consumption-ONE gal/hr (.85-1.25)
– 150 days per year to idle engine for HEAT* (*per US EPA)
– 10 hours per day = 1,500 hrs/yr
– Diesel Fuel Costs $4 gal*
(* Cost of diesel in Midwest $3.968 on 8/13/12
http://www.eia.gov/petroleum/gasdiesel/ )
1,500 idle hours x $4 = $6,000
Example above results in 33,300 pounds of carbon dioxide—for one truck, one year!
US EPA estimates that every gallon of diesel fuel burned results in 22.2 pounds of carbon dioxide.
Cost of fuel to operate the Espar Airtronic D2 bunk heater on medium is approximately $231 for same time period.

11. Works Like A Hot Water Heater
Espar HYDRONIC Engine Pre-heater
• Works like a hot water heater--Internal circulating pump provides engine
preheat throughout the coolant system so the entire block is warmed
• No plug-ins required which provides for convenience and flexibility.
• Available with timer/controller for fast preheat in advance
--requires only 1-2 hours for complete engine warm up
• Immediate window defrosting and interior cab warmth.
• Minimal power consumption which saves on batteries.
• Excellent pre-heating capability for combinations of on-board oils or fluids.
• Eliminate early morning idling for engine warmup
Idling damages the engine
from carbon deposits on
valves and pistons,
degradation of engine oil,
and accumulation of water
and sulfur in the engine

12. Vehicles -- Warm Engine Starts
Benefits-
• Less requirement for “jump starts”
• Less driver concern that truck engine will start
• Less wear on cold engine warming up
• Less public image issues from noise and smoke
• Less pollution from starting a cold engine
MORE PRODUCTIVITY

13. Idling Solution--
Espar E-Guardian Engine Pre-Heaters for School Buses
An Espar fuel-operated engine pre-heater
•Starts on a timer before the driver arrives and pumps warm coolant throughout the system
to warm the entire engine
•Uses a small fraction of the fuel used by the main engine
•Results in the defrosters producing warm air quickly for a safer view of the road
•Reduces the problems of morning bus “no starts”
•Is listed on the EPA website as an idle reduction solution

14. Idle Reduction for School Buses
Saves Dollars
Simple Example:
– Diesel fuel costs $4 per gallon
– Idling consumes nearly one gallon per hour
– Idling for 2 hours per day for heat and defrost
– 100 average cold school days per year
– Cost $8 per day to idle the bus
– $800 cost of fuel used to idle one bus per school year
– Lifetime of a school bus is 12+ years, $800 X 12 years = $9,600
Example above results in 4,440 pounds of carbon dioxide—for one year, one bus!
US EPA estimates that every gallon of diesel fuel burned results in 22.2 pounds of carbon dioxide.
THE FIGURES MAY CHANGE
But the message remains the same
IDLE REDUCTION SAVES BIG DOLLARS

19. New Espar Option
Defrosters Working BEFORE The Driver Arrives
• New option BLOWER CONTROL MODULE
used with Espar fuel-operated pre-heater, will
automatically start the bus defrosters at a
greatly reduced amp draw when the coolant
temperature reaches 86 degrees
• The windows can be defrosted BEFORE the
driver arrives--without running the engine or
depleting the battery-- includes low voltage
disconnect—further reducing the need to idle
the bus

20. Sometimes IT IS Easy Being “GREEN”
Positive Cash Flow
•Fuel-operated heaters are a “green technology” that
can actually pay for itself in fuel savings alone in
about 40 days on a class 8 truck or two to three years
on a school bus based on idling habits and cost of fuel.
•Result = For many years, the cash saved from reduced idling
stays in the school budget, municipal budget, or truck operations
Could decreased fuel consumption, decreased maintenance, and a
warmer vehicle keep your fleet on the road and in the budget?
Could a warmer, defrosted vehicle help to retain your drivers?
