Required
equipment:
− Two containers of approx. 10 to 20 liters volume.
− Use a suitable pump (drum pump) or a hose with funnel. Place the funnel as high as
possible so that the device can fill quickly.
− Fit connecting hoses between container, pump, cooling water inlet and between cooling
water outlet and back to container.
Change containers when
top one is empty.
Acting time:
Continue the pump stage until most of the foamy reaction, usually at the
start, has decayed. Generally, this is achieved after about 15 to 30 minutes.
