Technology Delivers Fuel Savings

Innovative design re-purposes wasted heat and saves energy

Graco’s patent pending dual coolant loop design ensures that the A and B materials are isolated from the engine coolant.

This unique design also provides constant, steady temperature control for superior heating performance.

Did you know...

Fast material heating

gets you up and

running quicker

With just one pass through

the heat exchanger, materials

can be heated to a Delta T

(change in temperature)

of 100°F (56°C) (140°F on

units with heaters)

. That’s 25%

greater than a standard Reactor

model. Because of this better

Delta T performance, you

don’t have to wait as long

for materials to preheat.

Engine coolant loop

Engine coolant goes through

heat exchanger 1 and transfers

the heat from the engine to the

coolant in the secondary loop.

Graco’s controls turn the radiator

fan on when additional cooling

is required.

Secondary coolant loop –

Coolant in the secondary loop

continually circulates when valve C

is open, maintaining a consistent

temperature. When material heating

is required, valve C closes, and

valves A and B open. This allows

the coolant in the secondary loop

to go through heat exchangers

2 and 3, thereby transferring the

heat to the A and B materials.
