1,500psi. The device uses proprietary flow-channels and breaker plate geometry to form a balanced polymer seal that promotes consistent screen displacement, says the company. Good results have been achieved in applications including flexible PVC precision tubing. Until recently, continuous filtration for flexible PVC has been limited by the polymer’s low melt temperature and high viscosity – which have led to processing challenges. The BPC screen changer has already been used by a leading manufacturer of flexible PVC tubing, says Hitech. “The success of initial trials led this processor to
retrofit all production lines at its US plant with Hitech screen changers,” said the company. At the same time, the company has developed its
Above: Hitech’s BPC screen changer can handle flexible PVC products such as tubing
a typical 90 minutes for competing technologies. “This is important if you consider that the screen
could need changing every three days, and that the line stops reduce overall production,” said the company. For this reason, Fimic has installed a line that
enables the screen to be changed without stopping the production line, using two filters in parallel.
Extreme conditions High-Technology Corp (Hitech) says that its new Model BPC screen changer that can filter under extreme conditions – such as high processing and differential pressure – without distorting or tearing the screen media.
It is designed to operate at processing pressures up to 5,000psi and differential pressures as high as
latest generation of PLC touchscreen control system that can adapt to varying conditions. Optional param- eters are configured via an automation algorithm, which detects real time processing conditions and adjusts the operations of the screen changer accordingly. “These innovations deliver major enhancements with
respect to performance, integration, reliability and ease of use,” said Aline Alroy, vice president of sales for Hitech.
