USE AND FUNCTION
FR 290, FR 490 and FR 590 Freezers are designed for the storage of the samples at low
temperature and it is used in the hospitals, blood banks, epidemic diseases research center,
research laboratories in the universities, genetic engineering, bio-pharmaceutical industry.
FR series Freezers are capable of cooling down to set points between -20°C and -45°C and keep
temperature stable within given tolerances. Temperature in the chamber is displayed digitally. It
is possible to set the working temperature in the range of -20°C to -45°C with 1°C sensitivity. FR
series freezers are safely operated via
N-SmArt™
microprocessor control system.
The refrigerant gas passes through evaporators placed under each shelf, bottom of the chamber
and top of the chamber; thus, each compartment of freezer is cooled directly. FR series provides
a stronger and more rapid cooling with its
DirectFREEZE™
technology. The refrigeration is
provided by non-explosive refrigerant gas which does not include CFC.
The power switch is equipped with a key lock to prevent unauthorized usage. Door handle on FR
series can be opened easily. Moreover, silicon gasket placed on the door protects air leakage.
FR series freezers has audible and visual alarm systems for high and low temperature
conditions, open door, power failure, temperature sensor failure and other faults associated
with the microprocessor control system. The alarm system is fed by an automatically re-
chargeable battery. FR 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. FR series offer GSM module as an option and
SMS can be sent to five different telephone numbers in case of error.
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.
FR series have internal memory which can store temperature values for 10 years. In addition to
internal memory, temperature values can be recorded in USB stick. FR 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.
