Premium Line KW series very-low-temperature freezers at -85 °C

Premium Line KW series very-low-temperature freezers at -85 °C The (High Security) series constitutes KW’s standard freezer line at -85°C; the (Premium Line) series represents excellence in very-low-temperature freezers for laboratory use. The (High Security Light) series constitutes KW’s standard freezer line at -45°C; the (Premium Line Light) series represents excellence in low-temperature freezers for laboratory use. The difference between both lines is in the control system and some components that, in the and versions, drive equipment reliability even higher, and thus the security of...

• Keyboard and display: The keyboard has an I/O switch, a MENU key to select functions, “+ “ increase and “−” decrease keys to modify parameter values for the functions selected with MENU, and an ENTER key to confirm the chosen values. The AUX key turns an auxiliary function on or off, if available (for example, the V230/1/50 recorder). It is possible to configure 5 different languages. • User security: the following functions are accessible only to the entitled personnel, through a dedicated password: - ON/OFF - T set-point change - Access to the Service Menu, for the function parameters....

Premium Line KW series very-low-temperature freezers at -85 °C Data logger: The controller periodically records the storeroom temperature. The data can be received and transferred to a PC by means of the Data Pocket transceiver and the serial receiver. The ColdMaster supervision software allows visualising and printing (in graph of table format) the recorded temperature data. The controller enters the records into two T channels. The memory capacity allows making an entry every 20 minutes for approximately 4 months. The IR transceiver automatically recognises the s/n of the controller card...

Premium Line KW series very-low-temperature freezers at -85 °C • Internal pressure control system with a two-stage refrigeration circuit that is topped by the KW NEW ICE AGE CONTROL® system The system continuously evaluates the T and pressure conditions of both refrigerating flows as well as the conditions of heat exchange with the environment, in order to maintain the balance between both stage flows; it also includes safety devices such as pressure gauges. All this guarantees that the motocompressors always operate under ideal design conditions and with maximum safety. COMPRESSORS...

Premium Line KW series very-low-temperature freezers at -85 °C STRUCTURE: - External cabinet made of zinc-plated and/or enamelled steel sheets, or, upon request, AISI 304 stainless steel satin finish. - Insulation in non-CFC, non-HCFC foamed polyurethane - Internal casing in AISI 304 (or AISI 316 upon request) stainless steel, with polished external BA finish for maximum resistance and cleanliness; LIFETIME WARRANTY ON STEEL PARTS - Triple-step seal in silicone rubber for greatest prevention against air loss and ice formation; gaskets with almost unlimited durability. - Gasket heating by...

REFRIGERATION: The refrigeration system is fully sealed; it uses a cascade circuit with innovative components and fluids to obtain, together, maximum cooling reliability and performance; it has 2 silent, airtight compressors (value Leq dB (A) < 55); with a high refrigeration capacity, furnished with magnetothermal protection and pressure gauge to monitor maximum condensation pressure (MR): full reliability and no failures in the 1st stage; immediate identification by the user with recovery ability. The condenser surface (air with thermal return above 2,610 Watt, with room T +25 °C) is very...

Upgrades and Innovations: - A softer seal than the previous one, but still triple, made of silicone rubber, 120 mm in width to minimise air leaks even more; the seal is heated by the overheated steam of the coolant; all this means no formation of condensation and no frost on the seal, no inlet of warm and humid air from the laboratory environment, better preservation of the samples in the compartment, less work for the compressors, energy saving. - 4 internal doors with a new, space-saving closing system; - use of racks with front removal (divided into various small drawers), Green ICE to...

-the front part of the freezer is completely closed and sealed along the whole perimeter, also with the help of a suitable frame to be placed between the appliance and the wall of the sterile chamber. - the air (or water or mixed) motor condensing system is wholly outside the sterile chamber; external grille for condensation air flow connections for condensation water pipes KW GUARANTEES OPERATION ALSO IN ENVIRONMENTS WITH NO VENTILATION -manufacture of all the external walls, door/s included, also in AISI 304 or AISI 316
