Find the right cooling unit to protect electronics and reduce downtime
A correctly sized cooling unit protects the electronics, extends their lifespan and minimizes downtime.
In this guide, we'll go over how to choose the right model – from wall and ceiling mounted to Peltier coolers.
1. Start with a Needs Analysis
To choose the right model you need to know:
- Heat generation: How much power does the equipment in the cabinet generate?
- Ambient temperature: How warm is the environment where the cabinet is located?
- Protection requirements: How warm is the environment where the cabinet is located?
- Location and design: Is wall, ceiling or semi-recessed mounting best?
2. Wall-mounted cooling units
Advantages:
- Easy installation and service
- Wide capacity range
- Flexible placement
Recommended for:
- Indoor installations
- Cabinets with medium to high heat generation
3. Roof-mounted chillers
Advantages:
- Takes up no space on the cabinet wall
- More even air distribution in the cabinet
- Modern design
Recommended for:
- Tight spaces
- Closely spaced cabinets
4. Semi-built-in chillers
Advantages:
- Discreet design
- Protected assembly
- Low noise level
Recommended for:
- Public environments
- When design and quiet operation are important
5. Peltier cooler
Advantages:
- Quiet operation and vibration-free cooling
- Maintenance-free
- Perfect for smaller enclosures
Recommended for:
- Small applications with low heat load
- Environments where vibration-free operation is required
6. Sizing – avoid over- or under-capacity
For optimal operation:
- Calculate the heat load in the cabinet
- Add a safety margin of 10–15 %
- Use the manufacturer's calculation tool or contact us for help
7. Care and maintenance
- Change or clean filters regularly
- Check seals to maintain correct IP rating
- Document operating times and service intervals
Checklist before buying
- Be aware of the heat development in the cabinet
- Know which mounting method is best suited
- Check if there are any special IP or EMC requirements
- Plan for service and filter replacement
- Ensure correct sizing
FAQ
When do I need a cooling unit?
If the cabinet becomes more than 10 °C warmer than the surrounding environment, or if sensitive equipment is affected by heat, a cooling unit is necessary.
What type of cooling unit is best suited for confined spaces?
Roof-mounted cooling units save space on the sides and provide more even temperature distribution.
