Screw plug heaters are a form of immersion heater used to heat gases and liquid solutions in smaller tanks where control is also required. A screw plug heater screws into the tank wall or vessel, or can also be installed within piping. The screw plug heater is immersed in the solution to offer rapid heating. Mechanical thermostats or digital controls allow screw plug heaters to achieve target temperatures accurately. Sheath materials include copper, steel, stainless steel, titanium, Incoloy®, and Inconel®. Energy-efficient NPT screw plugs are available in 1”, 1 ¼”, 1 ½”, 2”, 2 ½”, 3”, and 4’’.
Over the side heaters are designed to be installed in the upper part of a tank. Using this approach, there is adequate space available in the tank for operations. Using over the side heaters creates uniform temperatures while maximizing heat transfer. The over the side heater can be conveniently removed upon heating the liquids to the desired temperature. The portability of over the side heaters offers the flexibility to be used in various applications. Over the side heaters utilize heating elements made of steel, copper, titanium, or cast alloy, coated in fluoropolymer or quartz for added protection; diameter sizes include 0.315”, 0.375”, 0.430”, and 0.475”.
Silicone rubber heaters are used in low to medium temperature applications of up to 450°F that are irregular dimensions and shapes. Silicone rubber heaters are used to provide direct heat where traditional heaters are unable to be installed. Made of fiberglass reinforced silicone rubber, these heaters are highly flexible and durable. Silicone rubber heaters can be affixed to surfaces using pressure sensitive adhesives or field-applied adhesives, or they can be mounted mechanically using various methods. The standard thickness of silicone rubber heaters is 0.056”, with lengths ranging from 1” to 120” and widths ranging from 1” to 36”.
Digital control panels regulate temperatures, protect heating elements, and prevent overheating and other issues such as chemical disintegration. The control panel can be customized for your application to ensure safety while maintaining accurate and efficient heat transfer. Digital control panels offer ambient and target temperature readings for the solution being heated. There are multiple terminal box options available, including NEMA 1, NEMA 4, NEMA 7 explosion proof, dust-proof, and waterproof. The terminal box houses the various components of a digital control panel, including contactors, fuses, relays, and on-off switches. Digital control panels arrive ready to connect for quick installation, and are compatible with various materials including dangerous and corrosive materials.
