Free cooling systemsfor enclosures, cabinets & shelters
Wide capacity range
Compressor-free mode
Ambient-air cooling for telecom and industrial enclosures
Vikinor free cooling systems use ambient external air to cool cabinets and enclosures without relying on compressors. When conditions permit, they deliver major energy savings while maintaining safe internal temperatures in telecom, industrial, and utility installations. Also referred to as free cooling units, they are a proven alternative to traditional air conditioners.
Wide capacity range
From 600 W/K / 333 W/F small systems to 900 W/K / 500 W/F large-scale solutions.
Compressor-free mode
Cools using ambient air when conditions allow.
Hybrid or fallback mode
Integrated compressor/DX cooling engages when outside air isn’t sufficient.
Energy savings
Significantly reduces operating costs in most climates.
Sealed design
Maintains cabinet protection (IP55, NEMA 4 rating) with filtered intake.
Flexible installation
Supports side, top, or door mounting with configurable airflow direction.

Why choose Vikinor free cooling systems
Vikinor free cooling systems provide a cost-effective, energy-efficient alternative to conventional air conditioning. By using ambient air whenever conditions allow, they significantly reduce compressor runtime, lower energy consumption, and extend equipment lifetime — all while keeping enclosures sealed and protected.
In suitable climates, free cooling mode can cut energy usage by up to 96%, as the system uses outside air instead of compressor-based refrigeration. This results in substantial operational cost savings for telecom, industrial, and energy operators.
When ambient air cannot maintain safe internal temperatures, integrated fallback cooling (compressor or DX) automatically engages. This ensures uninterrupted operation of sensitive electronics in all weather conditions.
Our free cooling systems include filtered air inlets and maintain positive pressure to minimize ingress of dust, moisture, and corrosive elements. Sensitive electronics remain protected, reducing downtime and extending service intervals.
Systems are designed for industry-standard cutouts and mounting styles, making them suitable for both new cabinets and retrofit projects. Airflow and fan configurations can be adapted for site-specific requirements.
With intelligent control systems (optional SNMP / Modbus), operators can define free cooling thresholds, monitor system performance, and integrate alarms into network management systems.
