SynJets® are not only inherently reliable, they are designed to withstand demanding environments. All SynJets come with a standard five-year warranty. The coolers are designed for high temperature and low temperature operation, from -40°C to +70°C ambient temperatures. They thrive in hot, cold, and humid environments, so there are no worries about HVAC outages or temperature fluctuations affecting the cooler life. They are resistant to dust, fiber, and contaminant buildup, and are resistant to external bumps and vibrations in all three directions so routine maintenance, adjusting the lights, or accidents will not cause any change in the SynJet performance.
