How to choose the right air conditioning
Choose the right air conditioning for the control cabinet
The right air conditioning is essential to protect sensitive components, reduce downtime, and extend the lifespan of your cabinet.
In this guide, you’ll get help choosing the right solution – from filter fans to advanced cooling units.
Explore the right climate control solution for your enclosure
1. Start with a Needs Analysis
Consider:
- Internal heat production: How much heat does your equipment generate?
- Ambient temperature: Is the cabinet located in a hot or dusty environment?
- Protection requirements: Are there requirements for IP rating or special environmental requirements?
2. Filter Fans – For Basic Cooling
Filter fans are a cost-effective solution to:
- Reduce temperature in cases of moderate heat load
- Keep air circulating inside the cabinet
- Prevent dust ingress (with the right filter)
Recommended for:
- Indoor environments
- Cabinets with low to medium heat load
3. Cooling Units – For High Heat Loads
- Indoor / Outdoor environments
- Production facilities with high heat generation
When heat generation is high, or the cabinet is placed in hot environments, active cooling units are required.
Advantages:
- Maintain constant temperature regardless of ambient conditions
- Protect sensitive components from overheating
- Can be combined with remote monitoring
Recommended for:
- Indoor / outdoor environments
- Production facilities with high heat generation
4. PTC Heaters – For Cold and Humid Environments
In cold environments, heaters protect against condensation and frost damage.
Advantages:
- Reduce condensation and corrosion
- Prevent frost damage
- Ensure stable operation even in low temperatures
5. Control with Thermostats and Hygrostats
For optimal operation, air conditioning solutions can be automatically managed with:
- Thermostat: Keeps the temperature even
- Hygrostats: Regulate humidity
- Dual thermostats: Combining cooling and heating
6. Checklist for the Right Choice
- How much heat is generated inside the cabinet?
- What is the ambient temperature?
- Do you need cooling, heating – or both?
- Are there requirements for IP rating or EMC protection?
- Is control of temperature and humidity necessary?
FAQ - Frequently Asked Questions about Air Conditioning
When is a filter fan sufficient?
A filter fan is sufficient if the ambient temperature is low and the cabinet’s heat load is moderate.
When is a cooling unit required?
A cooling unit is needed when heat generation is high, or the cabinet is in a warm environment where passive cooling is not sufficient.
How can I avoid condensation in the cabinet?
By using heaters and hygrostats that regulate humidity and keep the temperature stable.
