Product Description
Our telecom cabinet heat exchanger provides efficient and stable cooling for outdoor telecom enclosures, communication base stations, wireless access cabinets, and 4G/5G outdoor equipment shelters.
It uses air-to-air heat exchange technology to maintain internal cabinet temperature while preventing dust, moisture, and contaminants from entering the telecom cabinet.
▼DC48v 325w/k dual control model air to air heat exchanger ▼
each board manages one fan (internal and external); if one fails, the other continues operating.
one channel for hardware failures (fans/sensors) and another for high-temperature alarms.
Equipped with a digital temperature controller for accurate monitoring.
Designed for harsh outdoor environments such as roadside cabinets, rooftop telecom sites, and rural communication stations.
No refrigerant, low power consumption, ideal for operators seeking lower OPEX and sustainable thermal management.
Sealed system, no filters required, reducing service time for telecom technicians.
Ensures internal equipment remains fully isolated from outdoor contaminants

Attention：
▶It is strictly prohibited to turn the air conditioner upside down or lie flat during transportation or handling.
▶Install vertically and make sure the polarity of wiring is correct and firm.
▶To avoid objects blocking the air circulation at the inlet and outlet of internal and external circulation.
▶If the protective cover is added, the vent area of the cover shall not be less than that of the air conditioner.
Application
Designed to maintain stable internal temperature for radio units, power systems, and battery modules.
Ensures long-term reliability in high-dust, high-humidity urban roadside environments.
Prevents overheating of fiber distribution frames and optical equipment.
