TRENT Folded and Formed® (F&F®) heating elements are ribbon type elements that were developed to meet the need for higher temperatures and improved temperature control demanded in today's heat processing operations.

First patented in 1933, TRENT's F&F® heating elements have a unique element configuration that is sometimes imitated --- never duplicated. Here are some of the performance advantages TRENT's Folded and Formed® heating elements provide for your electrically heated process equipment:.

• Greater direct radiation to the workload.

• More rapid heat dissipation, at lower watt density than conventional
  elements.

• Faster heat-up and cool-down.

• Maximum heating efficiency at lower element surface temperatures
   to prolong element life and minimize burnouts.

• Trouble-free, cost-effective, applied heat to meet your most
   demanding application.

TRENT Folded and Formed® heating elements are backed by more than 75 years experience in electrically heated equipment design and manufacture.

Why choose TRENT's F&F® heating elements?


1ST... because it starts as flat ribbon. And no other heating element dissipates heat more readily over more heating area! Compare a ribbon element 1” wide by .0159: thick, with a rod element of the same cross sectional area.

The rod would be 9 times thicker than the ribbon --- with less than one-fourth the radiating surface area. Result? Much of the heat is stored in the rod, instead of being dissipated. And that causes element burnout! Not so with ribbon elements. Its low mass will not allow heat to concentrate within the element. So it radiates optimum heat at low watt density. Ribbon is a more efficient heating element.

2ND... because it’s FOLDED. TRENT makes the most of the ribbon element by folding it to expose maximum flat radiating surface where it is needed most --- the work zone of the equipment being heated. Other ribbon elements do not offer this important advantage. Wound ribbon elements, for example, expose radiating surfaces to one another --- with only the element edges facing the work chamber. One element tends to heat the other. They hold heat. Too often they operate at higher surface temperatures than necessary --- and that costs money. Folded ribbon improves air recirculation, too. Heat is picked up more readily from the flat radiating side of the ribbon --- with only minimal airflow resistance from the edge of the element. In addition, folded ribbon heats up and cools down more quickly. There is practically no residual heat when the equipment is de-energized --- a significant advantage in maintaining close tolerances between process control set-points and actual temperatures.

3RD... because it’s FORMED. Greater structural strength is one obvious advantage. TRENT's unique forming process makes FOLDED and FORMED® heating elements virtually self-supporting. And they maintain their structural strength and stability over extended periods of use --- even at high temperatures where ordinary elements sag. TRENT Folded and Formed® heating elements require less heat absorbing support material. That not only makes them a more efficient and cost-effective heat source --- it makes them much easier to replace in your equipment when necessary. And note the concave surface of the FOLDED and FORMED® element. It exposes even more radiating surface --- and directs more heat to the work chamber than flat ribbon.

Why settle for less? TRENT Folded and Formed® heating elements are utilized in heater racks, plug heaters, electric ovens, electric furnaces, electric jackets, kettles, melters and hot plates. Talk to TRENT today.
