Tempered water system in modular design

To meet customers’ requirements, BKG is now delivering their systems in modular format. Each element can be installed individually. Thus changes in the equipment line-up to suit product requirements may be accomplished as quickly and easily as possible. The basic version of the new system contains the dryer and water tank with accessories for simple processes in the field of non-filled polyolefin’s.

Process water unit

After the separation of process water and pellets the water is filtered in the water tank by passing a screen pack-age. A water heating device is mounted at the water tank to heat up the process water before production starts as well as the piping for over-flow and refilling incl. valve. The water level inside the water tank is controlled by a measuring transducer and can be set independently to minimize the amount of refilled water or to avoid higher water losses.

The process water is primed by the water pump through the tubular or plate-in-frame heat exchanger to ensure the possibly necessary cooling. The regulation of the cooling water refill is done by a steadily working valve.
