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


• 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


• Turn chassis ignition key to Accessory

• By using Accessory chassis does not register hours.

• Switches (Left to Right)• Turn power on (1st Switch).• Depress Glow Plug (2nd Switch)

for approximately 30 seconds.• Press Crank (3rd Switch).• Turn on Aux Heater (LHG) (4th switch).

• Indicator Lights (Left to Right)• AHG Running

• Engine Running• LHG Active

• Liquid Heat Generator Running

• Glow Plugs• Glow Plugs Heating

• Engine Temp• Overheat

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


• 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


• 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.

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.
