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. Click here to see detailed view uneven heat profile
Section junctions provide large cool areas and a complete lack of consistency of temperature profile.

Conventional heater temperature profile shows areas of uneven, inconsistent heating

The Watt-Flex cartridge heater has a continuous coil running the length of the heater in one leg and then back again in the other leg. This provides an absolutely even temperature profile as shown seen here: 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

A magician worked on a cruise ship. The audience was different each week, so he was able to do the same tricks over and over again.

One problem: The captain’s parrot saw the shows each week and began to understand how the magician did every trick. Once he understood, he started shouting in the middle of the show:

“Look, it’s not the same hat!”
“Look, he’s hiding the flowers under the table!”
“Hey, why are all the cards the ace of spades?”

The magician was furious, but couldn’t do anything. It was, after all, the captain’s parrot.

Then the ship sank. The magician found himself on a piece of wood in the middle of the sea with the parrot. They stared at each other, but did not utter a word. This went on for a day, and then another and another.

Finally on the fourth day, the parrot could not hold back any longer.“OK, I give up.. Where’s the ship?”
