Rapid freezers for Plasma on contact KPFF 24B Model and KPFF 48B Model
KW in addition to the -40°C liquid bath freezer, proposes an alternative solution, satisfying however the technical advice and the normative in place, on the freezing time of the plasma bags.
The adapted principal of thermal exchange, in this case, does not use a cold bath at -40°C, but -75/- 80 °C surfaces, with which the bags are in direct contact.
The plasma bags, to be frozen, are immersed, vertically, in wells in which the walls are at least –75°C -80°C. The geometry of the wells is conical, to simplify extraction and formation of the solid bag, without any impediment for the increase in volume which happens when there is a passing in state from liquid to solid.
Internal case, made of 6 or 12 wells in inox AISI 304 steel (AISI 316 on request) with BA polished finishing, with rounded corners for easy cleaning; the external structure is in glazed inox AISI 304 steel sheet; the insulation is in polyurethane CFC and HCFC free, expanded in situ, with density of 40 Kg./mc. and with a minimum mean width of 140 mm., including the door; the door is mounted on the hinges with ABS cover, auto balanced. Triple gasket (absolute retention guarantee against air entry) in silicon rubber with welded joints, warmed up by the refrigerant and of unlimited duration.

Very-low-temperature freezers at −85°C (Premium Line)
The PL (Premium Line) series represents excellence in very-low-temperature freezers for laboratory use.
The difference both line is in the control system and some components that, in the PL and PLL versions, drive equipment reliability even higher, and thus the security of the products stored there, through exclusive and very innovative technical solutions.
KW, through a careful and complex research and development plan, has manufactured this completely new series of PREMIUM LINE ultra-freezers at -85°C, which constitute a super solution, or superior quality with respect to the already high standard of the HS series.
These KW ultra-freezers have renovated design and, in some aspects, functionality, such as the NEW ICE AGE KW CONTROL® and 4 KVA voltage regulator.
The PREMIUM LINE is available in four horizontal models and six vertical models.

The superb conductivity of the steel belt,
combined with excellent mechanical
properties even below -200°C (-320°F),
its joint-free surface and the ability to
slide products smoothly and cleanly from
the end of the belt, all contribute to
make it pre-eminent in food processing
applications.
