Product Description
The Cytech 120W/K air-to-air enclosure heat exchanger is engineered to deliver efficient, closed-loop cooling for outdoor telecom cabinets, power distribution boxes, battery energy storage systems (BESS), and industrial control panels. With a compact panel-mounted design and IP-rated protection, it ensures stable cabinet temperatures while preventing dust, moisture, and contaminants from entering the enclosure.
Designed for long operating life and maintenance-free performance, this 120W/K model is ideal for harsh outdoor environments where reliability is critical.
120wk enclosure heat exchanger datasheet .pdf
The unit delivers 120 watts per kelvin of thermal transfer capacity, helping maintain a safe internal temperature even when outdoor ambient heat fluctuates.
Air inside the cabinet is completely isolated from the outdoor environment.
This prevents:
dust
humidity
sand
corrosive gases
A perfect solution for sensitive telecom and electrical electronics.
The slim profile allows flexible installation on:
outdoor telecom cabinets
roadside equipment boxes
IoT and wireless base station enclosures
industrial control and automation cabinets
No filters are required, and no refrigerants are used.
The system runs quietly with low energy consumption and minimal service needs.
With IP-rated protection and corrosion-resistant materials, the heat exchanger withstands:
rain
dust storms
UV exposure
large daily temperature swings
An air/air counter-current plate heat exchanger is used to transfer the heat. Two centrifuge fans, one for the internal circuit and one for the external circuit provide ventilation.
The enclosure heat exchanger module is designed in such a way that the speed of the external circuit fan is controlled according to temperature, based on the pre-set pattern.
