Solid State Cooling Systems has established a strong, positive reputation for producing products which are significantly more reliable than compressor-based chillers. At least part of this improved reliability is inherent in the use of thermoelectric technology. Compressors typically have shorter lifetimes, because they continually run. Even variable speed compressors will wear out faster than thermoelectric technology. Thermoelectric modules have a typical lifetime of 200,000 hours. By using thermoelectric modules, with only one or two moving components (a pump and a fan), our products are inherently more reliable.
Another important factor in the lifetime of our chillers is our design approach. Although thermoelectric chillers are generally more reliable than compressor chillers, the approach to powering the modules is critical. Not all thermoelectric chillers are the same. Over our more than 25 years in business, we have developed a proprietary approach to configuring and powering our thermoelectric heat exchangers to ensure longer life.
Unlike compressors, our thermoelectric modules only turn on when needed. Once the targeted (Set Point) temperature is achieved, the feedback loop dials down the power on the modules. Power is only applied to precisely maintain a Set Point temperature.
Many of our products actually use a redundant design, so that if a thermoelectric module does fail over time, the chiller will keep working, just with reduced cooling capacity. In applications where the capacity of the chiller is higher than the max heat load, customers may not even know that a module has failed.
The last important factor in ensuring our products have world-class reliability are our proprietary assembly procedures and the skills of our assembly team. As an ISO 90001 certified manufacturing business, we pride ourselves on the discipline and attention to detail in production.
