Features:
• An economical cooling solution for applications where
cooling fluid temperature is higher than ambient and
temperature control is not required
• Quiet liquid-to-air cooling
• Positive displacement or turbine pump
• Built-in low liquid level indicator
Liquid-to-air cooling uses ambient air to cool your
application. Heated process fluid is pumped through the
3370’s fan-cooled heat exchanger and returned
to the process.
