Thermoelectric cooling systems can help get your delicate equipment to its destination safely without the added weight of a refrigeration system.
In many situations, custom cases are expected to be able to protect their cargo in a wide variety of scenarios. Most of the time people think of the specific shock absorption needs for their cargo to survive impacts and blows. But those dealing with extreme climate conditions need to also be aware of the temperature within the case as well. For desert-like conditions, traditional refrigeration technology is giving way to thermoelectric cooling because it is more versatile. Here’s why.
Works in Any Orientation
A custom case fitted with thermoelectric cooling can be mounted in any orientation owing to the absence of a refrigerant or compressor. This makes the case more flexible and able to use effective space. And if it ends up tipping over, as long as the air can still flow over the hot side, it will still work!
Lightweight
Transit cases need to be designed for effective portability and thus anything that adds to the weight of the case must be scrutinized carefully. Because they are constructed with solid state electronics, thermoelectric coolers are the lowest-mass means of temperature regulation available. This leaves more space and weight available for valuable cargo.
Built to Last
Because there are no moving parts in thermoelectric cooling systems outside of fans, there is nothing to wear down. Most manufacturers quote these systems’ lifespans at up to 150,000 hours – that’s 17 years of uninterrupted usage! Compressor systems, on the other hand, are more likely to wear out with the moving parts and seals inherent in their design.
Low Noise and Vibration
When you’re transporting delicate electronics or pre-assembled products, the last thing you would want to happen is a pump hammering against the side of the transit case. Thermoelectric cooling systems are completely silent save for the soft whirring of the fans so you don’t have to worry about your cooling system possibly compromising your cargo.
No Signal Contamination
The typical electrical system transported in a transit case is generally susceptible to the electromagnetic interference that a compressor system produces. But a thermoelectric cooling system is low voltage and solid-state, thus emitting practically zero electrical signals.
