Modern Energy-Efficient Heaters Providing Electronics Protection in Low Temperatures Environments




Delta's latest heaters are designed with intelligent energy use in mind and represent the company's commitment to crafting smarter and more energy efficient thermal solutions. At their core, Delta heaters utilize Positive Temperature Coefficient (PTC) heating elements to ensure that the selected temperature is maintained, avoiding costly waste from continuous heating. This thoughtfully designed operational mode prolongs the lifecycle between maintenance, avoiding overheating and burnout from unnecessary overuse. This allows electronics to maintain optimal operating temperatures for a longer period of time, despite low temperature environments.



Built for Safe Operation

Built upon decades of experience in creating safety measures, Delta engineers crafted this PTC-based Heater Series with multiple safety protection features including mechanical temperature switch, NTC sensor and fuse. The HEH100/150 models, in particular, have double isolation on their PTC device. On the whole, this Delta heater series offers reliable, durable and energy-efficient operation without compromising performance. To prevent possible PTC design vulnerability, Delta integrated high quality plastic for its heater casing to prevent plastic deformation and failure at high temperatures from the internal fan failing, and the fan inlet and/or outlet being blocked. Tests indicated a plastic case resistance with a comfortable buffer above the highest PTC operating temperature.
