1. INTRODUCTION
1.1. USE AND FUNCTION
MD 72, MD 120, MD 294 and MD 504 Medical Refrigerators are designed to store heat sensitive
products as drugs, vaccines, pharmaceutical and medical products. The medical refrigerators are
also suitable for any cooling application in the allowed temperature range.
MD series Medical Refrigerators are capable of cooling down between 0.0C and 10.0C and
keeps temperature stable within given tolerances. The circulation and homogeneity of the air
flowing over the stored samples 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.
MD series Refrigerators are safely operated via N-SmArt™ microprocessor control system.
Temperature in the chamber is displayed digitally. It is possible to adjust the working
temperature in the range 0.0°C to 10.0°C with 0.1°C sensitivity. The chamber is lit by a
fluorescent lamp and it is controlled electronically by a key on the display board. The on/off
switch of the device is equipped with a key lock to prevent unauthorized tampering.
Samples can be observed through a triple heat resistant glass door. Also, triple heat resistant
glass door provides that the ambient temperature does not have effect on the chamber
temperature. The self-closing door is equipped with magnetic gasket and with a key lock to
prevent unauthorized access.
MD 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. MD 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. MD series
offers 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.
MD 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. MD 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.
MD series Medical Refrigerators are manufactured according to the following standards:
EN 61010-1, EN 61000-6-3, EN 61000-4-2, EN 50419, EN 55014-1.
This device is in compliance with WEEE Regulation.
If mentioned warnings in this manual are not considered, NUVE will not be responsible from
their results.
