Manifold Heaters Frequently Asked Questions
A manifold heater is a type of industrial heating element designed to evenly distribute heat across multiple outlets or areas, often used to heat liquids or gases within a manifold system. The heater is typically used in processes such as heating fluid in industrial equipment, machinery, or chemical reactors.
A manifold heater works by providing heat to multiple outlet points within a manifold system. It consists of a heating element that is usually integrated into a manifold assembly. As electrical current passes through the heating element, it generates heat, which is transferred to the fluid or gas flowing through the manifold. This ensures that the fluid or gas is uniformly heated as it passes through the system.
