1. INTRODUCTION
1.1. USE AND FUNCTION
KN 72, KN 120, KN 294, KN 504 Blood Bank Refrigerators are designed for the storage of blood
and all blood components. Besides its usage for the storage of blood in blood banks, they can be
used for any cooling application in the allowed temperature range.
KN Series Blood Bank Refrigerators are capable of cooling down to set points between 0.0°C and
10.0°C and keep temperature stable within given tolerances. To control and monitor the real
temperature of the stored blood, the temperature is measured from a bottle containing a liquid
which has similar thermal specifications with blood.
The circulation and homogeneity of the air which flows over the blood bags is provided by a fan
assembled at the top of the chamber. It is supported by a defrost system that protects the
evaporator against icing and maintains cooling performance.
KN series Blood Bank Refrigerators are safely operated via N-SmArt™ microprocessor control
system. The power switch of the refrigerators is equipped with a key lock to prevent
unauthorized usage. Temperature in the chamber is displayed digitally. It is possible to adjust
the operating temperature between 0.0°C and 10.0°C with 0.1°C sensitivity. The chamber is
illuminated by a fluorescent lamp.
Samples can be observed through the triple heat resistant glass door. Also, triple heat resistant
glass door provides perfect insulation against ambient temperature fluctuations. The door is
equipped with magnetic gasket and with a key lock to prevent unauthorized access.
KN series have audible and visual alarm system alarm systems for high and low temperature
conditions, power failure, temperature sensor failure and other faults associated with the
microprocessor control system. As an additional safety feature, audible and visible alarm is
activated when the door remains open more than two minutes. KN series store last 50 failures
in the memory and these errors can be followed on the display. Standard Ethernet connection
feature enables email sending to five different e-mail addresses in case of any error. KN series
offers AlerText™GSM module as an option and SMS can be sent to five different telephone
numbers in case of error.
The alarm system is fed by an automatically re-chargeable battery. In case of electricity
interruption, the chamber temperature is measured and displayed as well. Remote alarm outlet
and the outlet for connection to central alarm system are offered as standard.
KN series refrigerators have internal memory which can store temperature values for 10 years.
In addition to internal memory, temperature values can be recorded in USB stick. KN series have
a weekly circular chart recorder as an option. The temperature in the chamber is recorded by
this chart recorder operated by the backup battery. Chart recorder is equipped with a key lock
to prevent unauthorized usage.
KN series blood bank refrigerators are manufactured according to the following standards:
EN 60601-1, EN 61010-1, EN 61000-6-3, EN 62366, EN 60601-1-4, EN 60601-1-2, EN 60601-1-6,
EN 980, EN 50419, EN ISO 14971.
This device is in comliance with WEEE Regulation.
If the warnings mentioned in this manual are not considered, NUVE will not be responsible
from their results.
