Frequently Asked Questions
What are the differences between DJ, DD, and DL model series?
The series differ by fin spacing and temperature application standards. DJ series has a 9mm fin space (evaporation temp -31℃), DD series has a 6mm fin space (evaporation temp -25℃), and DL series has a 4.5mm fin space (evaporation temp -8℃).
How does the design reduce fan operating noise and vibration?
The panel and side plates of the equipment adopt a stepped structural design, which is specifically engineered to effectively minimize noise and vibration during operation.
What pressure test do these air coolers undergo?
All products undergo and pass a strict 2.6MPa air tightness test to ensure stable operation and completely prevent leaks.
What are the options for the defrosting system?
The electric defrosting system uses high-insulation stainless steel heating tubes. Users can also install an optional controller module to enable automated defrosting control for improved efficiency.
How is maintenance and installation simplified?
It features a slotted frame structure for easy assembly, a detachable water pan and side plates for easy cleaning, and centrally integrated wiring and plugs within the electrical box.
