With the rapid rollout of 5G networks and edge computing infrastructure, outdoor telecom cabinets are facing harsher environmental conditions than ever before:

High Temperatures & Severe Corrosion: High-salt spray and humid environments along coastal or industrial areas cause serious corrosion to cabinets and thermal components.

Noise Complaints in Residential Areas: As base stations move closer to residential areas, fan noise from traditional cooling equipment frequently triggers noise complaints.

Energy Efficiency & 24/7 Reliability: Telecom equipment demands continuous operation, requiring thermal management systems with low power consumption and high reliability.

Engineered specifically for telecom applications, the LONGFAN CHEX00150-DC2-01-E011 Embedded DC Heat Exchanger delivers a quieter, more corrosion-resistant, and intelligent thermal management solution for critical telecom infrastructure! This telecom heat exchanger is designed for outdoor telecom cabinets, providing reliable thermal management for 4G/5G base stations and telecom enclosures.

1. IP55 Protection & Corrosion-Resistant Aluminum Housing

Designed for Outdoor Telecom Environments: Built with lightweight and high-strength AL5052 aluminum alloy, this telecom heat exchanger is designed for reliable operation in demanding outdoor environments. The IP55 protection rating helps protect the thermal management system against dust and water ingress, while the weather corrosion-resistant aluminum housing and surface coating provide enhanced durability in humid and coastal environments.

Durable Protection for Telecom Cabinets: Combined with a 10-mesh insect-proof netting, the enclosure provides additional protection against dust, insects, moisture, and other environmental contaminants. This robust design makes the heat exchanger suitable for outdoor telecom cabinets exposed to challenging environmental conditions.

2. 50 dB(A) Low Noise Operation for Noise-Sensitive Sites

Advanced Noise Reduction: Engineered with high-efficiency brushless DC fans and an optimized airflow path, reducing operational noise to a quiet 50 dB(A) level.

Smart Temperature Control: Supports stepless speed adjustments for internal and external fans based on cabinet temperatures. It operates quietly at low loads and boosts cooling under heavy loads, making it ideal for residential areas, parks, and roadside telecom nodes.

3. -48VDC Power Supply & 150W/K High Efficiency

Telecom Standard Power: Powered by standard -48VDC telecom power supply, with a low rated power consumption of only 98W.

Powerful Heat Exchange Capacity: Delivers 150 W/K heat exchange capacity and an airflow rate of 450 m³/h, operating reliably within a broad temperature range of -40°C to 70°C to keep telecom equipment running in its optimal temperature window.

4. Intelligent RS485 Remote Monitoring & Control

Smart Operation & Maintenance: Features an integrated RS485 communication port (MODBUS-RTU protocol) for remote measurement, signal transmission, and parameter adjustment.

Comprehensive Alarm Systems: Equipped with dry contact alarm outputs (NO/NC optional) and multi-protection self-diagnostic capabilities, drastically lowering manual maintenance costs.
