Protected enclosure
Internal and external air circuits remain separated.
Cooling for technical cabinets
Cabinet Air Conditioning for protected enclosures.
Compact air conditioners, heat exchangers and thermoelectric modules for telecommunications, energy, battery and automation cabinets with separated internal and external air paths.
- Closed loopseparated air circuits
- Outdoorweather-exposed cabinets
- Compactdoor or wall mounting
Coolnet solutionCabinet Air Conditioningselection and integration
Technology for critical infrastructure
Heat removal without opening the cabinet to ambient air.
Technical cabinets may operate in dust, humidity and changing outdoor temperatures. Closed-loop cooling removes internal heat while preserving enclosure protection.
The selection depends on heat load, enclosure size, target internal temperature, ambient range, solar gain and installation orientation.
Compact installation
Door, wall or enclosure mounting depending on the unit.
Environmental resistance
Solutions for demanding indoor and outdoor conditions.
Automatic control
Temperature regulation, alarms and communication by configuration.
Solution families
Select the architecture for the actual application.
The final configuration is confirmed after reviewing capacity, installation conditions, required availability and future expansion.
Active compressor cooling
Cabinet Air Conditioner
Closed-loop compressor units for cabinets with heat loads exceeding passive ventilation capability.
- Independent internal air circulation
- Compact wall or door mounting
- Temperature control
- Indoor and outdoor variants
Air-to-air transfer
Cabinet Heat Exchanger
Energy-efficient heat transfer where ambient air is cool enough, without mixing outside air with cabinet air.
- Separated air circuits
- Low power consumption
- No refrigerant circuit
- Suitable when ambient temperature permits
Thermoelectric cooling
TEC Cabinet Cooler
Compact solid-state cooling for smaller enclosures, control cabinets and localized loads.
- No compressor
- Compact construction
- Low maintenance requirements
- Heating/cooling options by model
Project selection
Integrated cabinet climate control
Cooling, heating, ventilation and monitoring selected as one enclosure environmental system.
- Heat-load calculation
- Ambient-temperature assessment
- Ingress-protection coordination
- Alarm and monitoring integration
Applications

Frequently asked questions
FAQ: Cabinet Air Conditioning
Why not use filtered fans?+
Fans introduce ambient air and contaminants. Closed-loop cooling is preferred when enclosure protection must be maintained.
When is a heat exchanger suitable?+
When ambient temperature is sufficiently below the required internal temperature and the calculated heat load can be transferred.
Can the equipment be installed outdoors?+
Selected models are designed for outdoor use; environmental ratings must be confirmed for the location.
Is heating also required?+
It may be needed in cold climates or for battery and control equipment with a minimum operating temperature.
How is cooling capacity calculated?+
From internal losses, enclosure heat transfer, solar gain, ambient extremes and target internal conditions.
