DESCRIPTION
CERTIFICATION IN CONFORMITY WITH DIRECTIVE 2007/47 ON MEDICAL DEVICES
The refrigeration line of KW (a brand that has been on the market for OVER 60 YEARS !) is made according to manufacturing standards that meet UNI EN ISO 9001:2008 and ISO 13485:2003. It is designed for medical applications (transfusion centres, transplant banks, stem cells, test laboratories, etc.) and also for pharmaceutical, biotechnological applications and in any other sector where validation and certii cation is required.
All models bear the prestigious certii cation to Directive 2007/47 CE.
THE KPFF series FAST FREEZERS also meet PED DIRECTIVE 97/23 CE.
TRADITION & DIGITAL REFRIGERATION WITH NEW ICE AGE (NIA)
The application of the NIA controller (the result of KW’s know how and expertise) allows the entire KW range of refrigerators, blood bank fridges and freezers to be connected with a PC, with local data networks and with an external data monitoring and i ling system, which can all be tracked from any other site through the Internet, etc. This of ers the best and utmost traceability of all the data and all events (alarms, blackouts, door openings/closings, etc.) useful for correct management of the blood, blood components, products and biological materials stored, according to ISO, SINAL, GLP standards (also according to CFR21), etc.
GREEN ICE PROJECT
KW is designing its laboratory refrigerators/freezers researching the best performance, with the lowest energy consumption and the least environmental impact. A permanent KW team researches into new solutions implementing dedicated equipment (test chambers) and software for C.O.P. (coei cient of performance) assessment, in accordance with environment protection laws.
FLEXIBILITY – VERSATILITY – INNOVATION
KW of er a very comprehensive range of equipment from the compact model to the freezer and to the very high capacity refrigerator (over 700 – 1500 litres), to meet all purposes and any functional solution … KW of ers all types of materials : from stainless steel (AISI 304-AISI316) to painted sheet metals, to plastics … KW of ers a very comprehensive series of accessories … -> so customers can custom build their refrigerator from the catalogue …

KW of ers SPLIT = remote unit solutions, with remote motor condensing units (away from the work area) owing to matters of size, thermal and noise pollution and ease of maintenance.
UTMOST PRODUCT SAFETY, ENERGY SAVING
The application of the NIA controller (together with all the other manufacturing and thermodynamic features) makes KW refrigeration equipment particularly reliable and with a low environmental and energy impact, through a series of functions/parameters that ensure the utmost ei ciency, top levels of operating safety and the best compatibility with the environment, including the routine operations of the laboratory for which they are intended.
In particular:
v Smart defrost (on some KLAB models), no frost solutions (all appliances, except some KLAB models), safety control, disaster recovery, environment adaptability, voltage stabiliser, integrated data logger function:
• Utmost safety of the material stored, even in the event of T sensor or CPU fault!
• Utmost ease of access and reading of all the controls and parameters on the LCD display
• Utmost ease of data coni guration, programming, control, i ling and monitoring, exportation of i led data to PC or in the network
• No defrosting (for almost all the range), or SMART- HOT GAS intelligent defrosting (not time-based, but on the measurement of the condition of the frost on the evaporator) which allows really considerable energy saving!

DIGITAL REFRIGERATION WITH NEW ICE AGE & WIRELESS REFRIGERATION
The application (also at the same time) of the two systems allows:
√ Continuous supervision in safety of the state of preservation of the samples stored
√ Traceability of all events with continuous and highly accurate recording through a specii c software
√ Considerable operating savings, during purchasing, installation and implementation and due to less samples lost owing to faults, etc.
√ Flexibility in the use of appliances, through wireless communication and with a broad range of alternative solutions
√ The solutions proposed by KW are compatible with the accreditation - certii cation of the laboratory they are intended for
