Dry Cooler
V-bank free cooling
When ambient air is colder than your return fluid, running a compressor is wasted money. GPTECH dry coolers give that back: a V-bank coil, EC fans and a control curve that stages capacity so the plant coasts on free cooling whenever the weather allows.
-
Zero water consumption
Fully dry heat rejection — no make-up water, no treatment chemicals, no legionella risk.
-
EC fans, staged
Fan speed tracks load; sound and power fall sharply at part load.
-
Free cooling hours
In northern China climates, free or partial free cooling covers the majority of the year.
-
Coil protection
Optional coated fins and guards for coastal, dusty or corrosive sites.
