Just How Long?

How long does a Watt-Flex® cartridge heater last? This is a common question that does not have a definitive answer. The lifespan of a Watt-Flex® cartridge heater depends on a variety of factors including size of the bore, heat sink material, watt density of the heater, set point temperature, type of controller, amperage (function of voltage), presence of contamination, shifts per day and a number of other factors. We state that our heater will last up to four times longer in the same application as a conventional heater ... but where do we get that number?

In house tests can be skewed to produce favorable results so we choose to look at real world applications and measure our success from customer testimonials. Back from a recent sales trip, one of our sales guys reported that he was in a shop looking at a machine being rebuilt. As part of their PM the customer was replacing the Watt-Flex cartridge heaters and gave him the old units. From the date code he found the heaters was over 11 years old and had operated almost continuously with a fairly high watt density. Further tests on the heaters proved them to be not only electrically sound but still within the resistance specification.

This customer had tried less expensive conventional heaters but never got more than one year's service from them. We are always promoting the issue of price vs. cost ... this is one customer that understands the concept well.

Friday Funnies

A young businessman had just started his own firm. He had just rented a beautiful office and had it furnished with antiques.

He saw a man come into the outer office. Wishing to appear the hot shot, the businessman picked up the phone and started to pretend he had a big deal working. He threw huge figures around and made giant commitments.

Finally he hung up and asked the visitor, ''Can I help you?''

''Yeah, I've come to activate your phone lines.''
