• Faster, more powerful devices produce more heat
• Higher density of electronic devices used in control applications
• Devices not hardened to environmental extremes
• Relationship between high performance & temperatures & reliability
• Customers seek ‘insurance’ solutions to protect from costly shutdowns.

Properties of silicone materials change
Drive performance is de-rated I/C based devices may experience
intermittent fluctuations in output and voltage migration
Mean Time Between Failure (MTBF) decreases exponentially

Wichtige Zertifizierungen
30© Pentair Technical Products
Use when: Air surrounding cabinet is too hot, dirty and/or corrosive to cool the electronics Temperature inside cabinet needs to be cooler than temperature outside of cabinet Or when humidity control is desired inside the cabinet
+ Below ambient cooling+ Large capacity cooling+ Maintains integrity of cabinet seal
(closed-loop)+ Controls humidity in the cabinet+ Powered by 115, 230 or 400 AC
voltages+ Filterless V-Series
Pros:
- Higher up front investment- Higher costs to maintain- Can generate condensation- Large & heavy sizes- High energy consumption
Cons:
Ambient = air temperature outside of enclosureExample: If temperature in factory is 40°C (ambient), it is possible to cool the enclosure to a temperature below 40°C with an air conditioner.
Air Conditioner
31© Pentair Technical Products
Use when: Air surrounding cabinet is too hot, dirty and/or corrosive to cool the electronics Temperature inside cabinet slightly higher than temperature outside cabinet
+ Highly reliable/long life cycle+ Filterless (low maintenance)+ Lower up-front & ongoing costs+ Maintains integrity of cabinet seal (closed-
loop)+ AC or DC power
Pros:
- Does not cool below ambient (Ti>Tu, 5°C)- Large size if high heat loads- No humidity control in the cabinet- Less efficient than fans & blowers
Cons:
Closed-loopRe-circulates clean enclosure air separately from the ambient airflow system – maintains integrity of cabinet seal
Air / Air Heat Exchanger
32© Pentair Technical Products
+ Below ambient cooling+ Compact & lightweight+ Maintains integrity of cabinet seal+ No refrigerant+ Filterless (low maintenance)+ Powered by 24 or 48 DC voltages+ Able to heat with reverse polarity
Pros:
- Small cooling capacity- Higher cost than filter fans (but provides below
ambient cooling)- Can generate condensation- Energy inefficient in most cases (high power
consumption
Cons:
Use when: Air surrounding cabinet is too hot, dirty and/or corrosive to cool the electronics Temperature inside cabinet needs to be cooler than temperature outside of cabinet A normal air conditioner may not fit the space A low level of cooling is required (up to 682 BTUs or 200 Watts per hour)
