SEIFERT WLK 301
Water Cooling Aggregate

GEIT-30097GB (9/04)
The WLK 301 is an air-cooled refrigera-
tion aggregate designed to facilitate an-
ode heat dissipation of the X-ray tube
when operating at high ambient temper-
atures and can also be used when, for
economical reasons cooling of the X-ray
tube from the water supply is not fea-
sible.
The aggregate is mounted in a square
tube frame and is mobile on 4 castors.
The aggregate is equipped with CFC-free
coolant. The "fail-safe" flow rate moni-
tor, used for our ID 3003 X-ray equip-
ment is not implemented.
