HP2000 Auxiliary Power Unit A Quiet Heat Pump System
With over 12 years in development and on-road testing, the HP2000 Auxiliary Power Unit is specifically 
designed for the transportation industry. It is built to handle the extreme temperatures and conditions drivers’ battle every day. By eliminating the need for the truck’s engine to idle, fuel usage is reduced significantly. While at the same time, the driver can enjoy all of the comforts that are associated with an idling engine.
Manufactured In The Heart Of The U.S.A.
For over a decade, Parks Industries, LLC has been designing and building APU’s in the heart of the USA. We have furnished our APU to Overseas Military Applications, Airports, Construction Equipment, Emergency Vehicles as well as Class 7 and 8 trucks.
How our unit heats where others don’t
In a typical heat pump system, energy in the atmosphere is transferred from outside to heat inside. The problem is that at the temperatures nearing zero degrees, there is not enough heat outside for the system to work. 
Our heat pump system is different. With our patented system reversing, our unit’s fan and other components reverse in heat mode to pull heat off of the engine. This translates to air temperatures in excess of 120� at outside temperatures below zero!
Mounts on frame rails
The HP2000 mounts on approximately 21″ of frame rail. No drilling of the frame rail is required. With a clean frame rail, the complete installation can be achieved in about six hours.
Evaporator Unit
The evaporator unit conveniently mounts in a storage compartment. If you choose, the air ducts can we connected to outlets in your truck. Compact in size, the evaporator is a mere 17″ x 8″ x 8.5″ and will almost anywhere in your cabin or storage compartment.
APU units provide Cost Savings
Turning your main engine off whe
n you are parked has several advantages including, emissions reductions and substantial fuel and engine maintenance savings. New, no-idle legislation is being adopted in the U.S. and Canada. This is intended to reduce emission, lower noise, and save fuel. The Hp2000 is the perfect solution to this dilemma, allowing you to enjoy all of the benefits of a running engine.
