Profiled for Performance
We continue to run into applications in which our customers experience uneven heat across the profile of their work surface. The continuous coil, a product of the unique design of the Watt-Flex® cartridge heater, provides several benefits that immediately translate in customer applications. Conventional heaters of 8 inches or more have two (or more) sections of resistance coil, each wired in parallel to two rods that transverse the heater.
The first disadvantage of this construction is that heat-up is extremely uneven as shown in the customer generated data below. For detail of this chart, go to: http://www.daltonelectric.com/EWW/Competitor-Profile.htm
Section junctions provide large cool areas and each of the coil provide their own profile spike, resulting in a complete lack of consistency of temperature profile.
.
The Watt-Flex cartridge heater has a continuous coil running the length of the heater on one leg and then back again on the other side. This provides an absolutely even temperature profile as shown at: http://www.daltonelectric.com/EWW/Dalton-Profile.htm
The temperature drop that you see at either end of the measurement is a result of the technique by which the customer measured temperature. It was done on the outside of a sealing bar and demonstrates the radiant temperature loss of any heat sink. Often, due to the even profile of the Watt-Flex heater, it can replace a conventional heater with distributed wattage to compensate for this heat loss.

Friday Funnies
Two young men were out in the woods on a camping trip, when the came upon this great trout brook. They stayed there all day, enjoying the fishing, which was super. At the end of the day, knowing that they would be graduating from college soon, they vowed that they would meet, in twenty years, at the same place and renew the experience.
Twenty years later, they met and traveled to a spot near where they had been years before. They walked into the woods and before long came upon a brook. One of the men said to the other, this is the place! The other replied, No, it's not!. The first man said, Yes, I do recognize the clover growing on the bank on the other side. To which the other man replied, Silly, you can't tell a brook by it's clover.
