5 5 © Pentair Technical Products Heat can come from sources inside the cabinet... Indoor Industrial, Telecom & Data Networking AC power supply Controllers (PLCs) Drives & servos Transformers Radio equipment Battery back-up Server racks Processors Inverters Contactors & relays Resource of damaging heat

6 6 © Pentair Technical Products... outside the cabinet... Indoor Industrial & Telecom Welding process Paint oven Solar heat gain Blast furnace Foundry equipment Resource of damaging heat

7 7 © Pentair Technical Products... from the electronics themselves... More electronics going into same size or smaller enclosures Datacom, telecom demanding higher performance More server functions mean more heat Resource of damaging heat

8 8 © Pentair Technical Products Semiconductor transistor density and performance double every months. Moores Law Named for Intel founder, Dr. Gordon Moore... as performance increases... Effect of damaging heat

9 9 © Pentair Technical Products At extreme temperatures... Catastrophic failures 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 Effect of damaging heat

10 10 © Pentair Technical Products What does it cost to shut down an automotive assembly line for 1 hour? Over $500,000 Effect of damaging heat

11 11 © Pentair Technical Products Consider the costs associated with the following... Productivity losses of plant/line shutdowns Labor Scrap Opportunity cost Component costs In warranty – processing costs, labor Out of warranty – out of pocket costs Material & Labor Customer satisfaction costs Missed ship dates Effects of damaging heat

30 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 enclosure Example: 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 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-loop Re-circulates clean enclosure air separately from the ambient airflow system – maintains integrity of cabinet seal Air / Air Heat Exchanger

32 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) Thermal Electric Coolers
