Product Description
An outdoor cabinet heat exchanger is used when telecom or electrical cabinets require efficient cooling in dusty, humid, or harsh environments. It removes heat from inside the enclosure without using fans that draw in outside air, keeping equipment safe from dust, moisture, and contaminants. Ideal for outdoor telecom cabinets, battery enclosures, and industrial control panels operating in hot or challenging climates.
An outdoor cabinet heat exchanger 150W/K is a cooling device designed for telecom or electrical cabinets that dissipates heat at a rate of 150 watts per Kelvin of temperature difference between the inside and outside of the enclosure. It provides efficient, maintenance-free cooling without introducing outside air, protecting sensitive equipment from dust, moisture, and harsh environmental conditions.

Closed-loop system maintains a sealed cabinet environment.
Meets global environmental standards and reduces maintenance.
Designed for unmanned, remote, and extreme-weather locations.
Low energy use + maintenance-free = significantly lower operation cost.
Air to air systems use up to 80% less energy.
Almost zero maintenance — no filters, no refrigerant leaks.
Air to air heat exchangers reduce long-term costs and improve system uptime.
The internal hot air passes through a heat exchanger core where heat is transferred to the outdoor airflow, maintaining stable internal cabinet temperature.
Completely prevents dust, moisture, insects, and pollutants from entering.
Optimized fans ensure stable airflow even in hot climates.
Available for different thermal performance requirements.
12V DC, 24V DC, 48V DC, and 230V AC options for any installation.
