Tips for customers
How to choose a most suitable type of screen changer for your extrusion line ?
After the equipment supplier making a size recommendation and then you should perform your own analysis to confirm appropriate sizing. That way, you will have the advantage of independent analyses and, best of all, there is no additional cost.
Learn the difference between price and cost. Be sure to take into consideration all of the variables and look at all the factors to determine the real cost of ownership for the screen changer. Some of the hidden variables to consider may be:
?Product quality.
?Maintenance, time and cost of parts.
?Process downtime and cost.
?Life expectancy for the equipment and amortized cost of ownership.
?Cost and availability of filtration media.
?Pressure loss and effect on line output and product quality.
?Operator safety.
?Required operator intervention and labor cost.
If all of these and other factors are taken into consideration, you can choose the most suitable solution, and then you can expect a much better return on investment.
