Description of Appliance
Classification
The CRYOFUGE 6000i and the CRYOFUGE 8500i are temperature controlled, microprocessor driven and
programmable laboratory centrifuges for universal use in large laboratories, blood banks and other opera-
tions of the pharmaceutical and bio-technical industries. The CRYOFUGES are built as floor-standing appli-
ances with frequency controlled and maintenance-free induction motors and are designed for a wide range
of accessories. They belonged to group 3 according to the German Medical Appliance Ordinance (Med
GV). In the framework of European harmonisation, the Med GV was replaced by the Medical Product Law
(MPG).
Definition
The CRYOFUGES are surrounded by a stable and completely welded sheet steel housing. The rotors are
driven directly by a frequency controlled, maintenance-free induction motor with high acceleration perform-
ance. This motor runs with little noise and vibration, even at high speeds, and has an extremely long life
cycle. It is secured on the bed plate preventing vibrations and is sealed by a rubber flange towards the rotor
chamber. In order to control the temperature, the appliances are equipped with compressor systems for
environmentally friendly refrigerants.
The central processor monitors the sequencing, the speed measurement and control, the temperature
measurement and control, the safety systems and the error messages of the centrifuge.
An additional microprocessor is responsible for the key and display functions and is also used for saving
parameters. The practical SEPACONTROL system takes care of the operation and programming of the
centrifuge.
Safety Equipment
Rotor chamber armouring
The high-grade steel rotor chamber is surrounded by a massive armoured boiler. This armouring is able to
absorb the full rotation energy in the case of a rotor crash.
Lid lock
The centrifuge lid can only be opened when the rotor speed has dropped to < 10 rpm and the appliance is
connected to the electricity supply. The centrifuge can only be started when the lid is correctly locked on
both sides and the "OPEN" display disappears.
Thermal motor and electronic protection
In the case of the motor or the heat dissipater overheating, the power electronics is switched off, in order to
protect the drive and the electronics against damage (error message "E-08").
Imbalance switch
The drive system is provided with an imbalance switch to protect against inadmissible imbalances. If the
permitted imbalance is exceeded, the LED "imbalance" is alight, accompanied by an intermittent alarm, and
the centrifuge automatically decelerates until it comes to a standstill.
