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.

Progress Of Project

May 2, 20234

Chassis Mounted Arctic Heat Generator • 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.

AHG Operation

May 2, 20236

Chassis Mounted Arctic Heat Generator (AHG)

Key Benefits:• Provides 80,000 BTU

heated coolant almost instantaneously.

• 12V 140 Amp electrical power for battery charging & electrical demands.

• Reduced emissions & fuel consumption.

• Increased equipment uptime.

• Extended equipment lifespan.

• Available in 12V or 24V configurations.

May 2, 20237

Chassis Mounted Arctic Heat Generator (AHG)

• Arctic Heat Generators are designed for use when chassis engine is not operating.

• Beginning of season turn master switch on.

• Leave master switch on all season.• Most units are equipped with

master switches.• 2015 units and new units master

switch is by passed (uses chassis master switch).

May 2, 20238

Chassis Mounted Arctic Heat Generator (AHG)

• Turn chassis ignition key to Accessory

• By using Accessory chassis does not register hours.

Duel Heating SystemChassis Mount AHG With Chassis Engine Mounted LHG

May 2, 202312

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.

May 2, 202313

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°.

May 2, 202314

Chassis Engine Mounted Liquid Heat Generator (LHG)

• 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.

May 2, 202315

Non Mobile Equipment

May 2, 202316

Non Mobile Engine Mounted Liquid Heat Generator (LHG)

• 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.

May 2, 202317

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.

May 2, 202318

Future Applications• 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.
