The PH Hopper Heating Module is a rugged design, the high-performance heating surface of the hopper. The Marathon hopper heater are self-contained heaters whose designed provide heat outputs up to 3 watt/squire inch, with a maximum circuit size of 4500watts depending on the application, the design of the hopper heater is such that it distributes heat over its entire surface. The  PH module is according to customer requirements of surface heating area and application. The heater is offered in multiple designs, each one includes a heater element made of Inconel/Nichrome/SS. The heater element which provides multiple flow paths for electrical current to pass. This design eliminates the burnout chances common with series wire-based design.


  • Parallel circuit high-temperature alloy heating element.
  • Temperature-rated insulation- Mica and glass wool.
  • Aluminum/Aluminized steel protective enclosure and its cover with mounting channel attachment.
  • High temperature insulated lead wire for connection

Hopper Heating Modules for Power Plants
Conveying coal/oil (other material) from stockpiles to boiler during winter months is a well-documented nightmare for plant operators. Identical conveying problems exist within the mining industry as coal is moved around the mine site.  Coal stored outdoors on the stockpile or delivered by unit train or barges picks up moisture from rain and snow. When this wet or frozen coal is conveyed, it inevitably comes into contact with the plate steel of the various hoppers and chutes within the coal handling system. During winter, this plate steel is below freezing for extended periods. When wet or frozen coal encounters steel at sub-freezing temperatures an instantaneous bond is formed. This bond causes immediate and often catastrophic blockage of the hopper and chutes. The bond and resultant blockage are so severe that often pneumatic drilling equipment and explosives are required to free up the system. This problem, known as  Flash Freezing, is extremely inconvenient and very costly. Several cases are documented where utility and industrial boilers have been shut down due to blocked conveying systems.
