• 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.

Wichtige Zertifizierungen


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


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


+ 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)
