2. History Of Alpine AHG Use
• Fall 2013 CPAI & Ventech met to develop a Prototype
AHG in an effort to reduce engine idle time.
• April 2014 two prototype AHG installed on Kenworth
tractors.
• In a compressed but controlled testing schedule
benefits were noted during the test.
• At the completion of the 2014-2015 ice road season,
11 AHG units were in operation in the Alpine Field.
• The AHG Project is successful and is expanding in use.

September 14, 20164
• The Puritan AHG reduced heavy truck engine operating time by an average of 53% during the 2014-2015
ice road season.
• An average of 53% reduced operating time will allow extended replacement schedules. A large impact
upon the way the Alpine capital budget is spent.
• Alpine reduced fuel costs by $100,288.80 across 8 units, an average fuel savings of $12,536.10 per unit.
(Based on $4.00 per gallon)
• Averaged AHG hourly cost of operation (fuel & maintenance) is $2.83.
• The largest benefit is seen when the AHG is installed at time of equipment acquisition.
• Larger savings are expected as the project expands to other applications through manager and equipment
operator involvement.

11. Chassis Mount AHG With Chassis Engine Mounted LHG
September 14, 201611
12. Chassis Engine Mounted Liquid Heat Generator (LHG)
• The 2015 5500 gallon tank
trucks are equipped LHG.
• Both trucks are equipped with
chassis engine mounted (LHG)
in addition to the Arctic Heat
Generator (Chassis Mounted).
• Purpose:
• Diesel/Urea Truck require heated
Urea (DEF) tank and pump house to
prevent freezing.
• Maintains engine and exhaust gas
temperatures while chassis engine is
running.
• This is an independent system
designed for use when main
chassis engine is operating.

13. Chassis Engine Mounted Liquid Heat Generator (LHG)
• The Liquid Heat
Generator (LHG) is
engine mounted in place
of an AC Compressor.
• The LHG is coolant
temperature activated.
• The main Chassis engine
is designed to maintain
220° operating
temperature.
• The LHG is designed to
maintain coolant at no
less than 180°.

• Two position push switch:
• Located upper left gauge blank
• Light (switched in) on
• No light (switched out) off
• Can be left in the “on” position.
• LHG will only operate when heat is needed.
16. Non Mobile Engine Mounted Liquid Heat Generator (LHG)
September 14, 201616
• Tier 4 engines in non-mobile equipment bring a new challenge as to how to maintain engine
and exhaust temperatures in the arctic. New tier 4 diesel powered, non-mobile equipment
began arriving in 2015.
• Equipping the units with the LHG keep the engine under a constant load, maintaining
proper operating temperatures and increasing exhaust gas temps.
• With the increased exhaust gas temperatures wet stacking is eliminated and efficient
engine regeneration occurs.
17. Non Mobile Engine Mounted Liquid Heat Generator (LHG)
• MQ Power Genset equipped with engine mounted LHG.
• Two position switch:
• Light (switched in) on.
• Not light (switched out) off.
• Located on control panel.
• Can be left in the “on” position.
• LHG will only operate when heat is needed.
• LHG will disengage or engage based on engine load created by power generation needs.
• Controlled through load sensing module.

18. • Cranes:
• Replacing Generators with Arctic Heat Generators will provide heat to the cab and
engine while powering 12/24V boom lighting.
• Pickups:
• A potential of test pickups with engine mounted Liquid Heat Generators in an
attempt to increase exhaust gas temperatures to improve engine regeneration.
• Box Van Generators:
• We are currently working towards the upfit of Box Van Generators with a Liquid
Heat Generator. Creating a Arctic Heat Generator using our existing infrastructure.
• In future Box Van with invertor builds may use a 2 cylinder Arctic Heat Generator
to provide heat and 12V power to the chassis engine, cab, and box.
• Heavy Equipment applications may be explored in the future.
