Controllable Gas Springs KF2Cooling & Heat Factor Reduction
KF2 modelH
ea
t F
act
or
= No Cooling Required
= Liquid Cooling Range
= Nitrogen Cooling Range
To reduce Heat Factor:
Add more KF2 springs & reduce overall gas charge pressure
Increase KF2 model size and decrease gas charge pressure
Reduce press cycle frequency
Heat Factor = Stroke Length x Frequency
Heat Removal
Liquid Cooling:
10 kW or 25 kW cooling capacity
Increases SPM up to 400%
Requires 380V AC power supply
Controllable Gas Springs KF2
Nitrogen Cooling:
1.5 kW cooling capacity
Increases SPM up to 500%
Requires 24V DC power supply
