SPECIFICATION SHEET POWERSAFE, Watlow’s Medium Voltage Integrated Heater and Control System, Offers a Clean and Safe Thermal Solution POWERSAFE™ is a fully integrated medium voltage control and heating solution that offers longer heater life, allowing you to confidently replace fossil fuel solutions with a clean electric solution. It also meets the necessary agency requirements to help make your process safe and reliable. Wattage size requirements for electric thermal equipment have been on the rise. This makes medium voltage solutions attractive because they reduce overall installation costs compared to traditional electric heat exchangers. Watlow’s POWERSAFE medium voltage solution eliminates the need for additional cabling and step down transformers typically required with lower voltage systems. This translates to significant reduction in installation costs. If you are looking for a solution to decarbonize your existing systems, Watlow’s POWERSAFE medium voltage solution provides a clean, reliable and fully integrated system with optimal fluid dynamics that requires even less space to operate.
