The Whole Length

Cartridge heater customers are continually amazed when they learn about the construction of a conventional heater. 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 a complete lack of consistency of temperature profile.

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 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

Little Tony was staying with his grandmother for a few days. He'd been playing outside with the other kids for a while when he came into the house and asked her, "Grandma, what's that called when two people sleep in the same room and one is on top of the other?"

She was a little taken aback, but she decided to just tell him the truth. "It's called sexual intercourse, darling."

Little Tony just said, "Oh, OK," and went back outside to play with the other kids.

A few minutes later he came back in and said angrily, "Grandma, it isn't called sexual intercourse. It's called Bunk Beds. And Jimmy's Mom wants to talk to you.
