Testers check heat exchangers without
stopping
Testers being marketed by a UK company can detect cracks within five minutes in heat exchangers used to pasteurise products such as milk, water, soft drinks and juice, according to a spokesman.
Testers being marketed by a UK company can detect cracks within five minutes in heat exchangers used to pasteurise products such as milk, water, soft drinks and juice, according to a spokesman Food processors are required by due diligence to test their heat exchangers at regular intervals as faults can develop causing problems with products that might not be detected until after release and consumption

Easytest's Hexteq system detects cracks within five minutes in heat exchangers used to pasteurise products such as milk, beer, water, soft drinks and juice, according to a spokesman.
Testers add intelligence to maintenance
Easytest has upgraded its heat exchanger test systems for the dairy and beverage industries.
The four heat exchange testers being marketed by Easytest can be used to certify and calibrate liquid food processing equipment and give instant certification and printed graph of the condition of the equipment for quality records.
Most other heat exchanger crack systems require plant to be out of use for up to eight hours, says dairy consultant John Watson, who is responsible for marketing the Easytest series of systems.
The old systems also usually require the heat exchanger to be stripped down and painted with dye or gas pressure tested with all the usual environmental and safety concerns involved in this old technology Easytest's Hexteq system takes five minutes and can be carried out when there is liquid under pressure in the heat exchanger.
The testers, which were launched last year, use pressure and ultrasonics to detect cracks and pinholes that may be present in a heat exchanger.
The company's Pasflo detector and Pasflo-UHT use similar technology and can be carried out while the exchanger is still running.
Pasflo measures and records the holding time, which dairy processors are required to check at least annually.
Magnerscan also uses a similar technology.
The tester uses no chemicals, dyes or gases and can detect minute flaws in vessels.
Not only are the cost savings of this system significant but more significant to processors is not to have the worry of a plant being out of commission for a prolonged period for a simple test to be carried out.
