POL-EKO Ultra-Low Freezer ZLN-UT 300 in Refrigerators, cooling technology

GFL Upright Freezer 6485: GFL Chest and Upright Freezers are used successfully in more than 70 countries all over the world. Both product ranges are designed for ultra-low temperatures of ± 0 °C to -40 °C and -50 °C to -85 °C, for long-term storage and quality assurance of organic substances and other materials.

GFL Upright Freezers are produced with high-quality, thoroughly tested materials only. They have been proven in continuous operation, work trouble-free, extremely silent and are maintenance-free. All models are equipped with microprocessor technique as well as with an interface module for comfortable remote control, monitoring and registration of the temperature values via PC.

Only a safe temperature protection ensures trouble-free long-term storage of cell lines, human, animal and plant tissues, fractions of the blood, vaccines, or reference cultures of micro-organisms, such as bacteria, yeasts, viruses and fungi.

• User-friendly microprocessor technique.
• Comfortable control panel with digital display to enter and read out all security-relevant data.
• Adjustable alarm limits for over- and under-temperatures (1 - 20 K).
• Additional control and alarm options, individually settable for different user applications.
• Maintains all display and alarm functions for 60 hours in case of a power failure (accumulator time allowance).
• Electronic alarm device and potential-free contact for connection to an internal alarm system, or to the central I&C system.
• RS 232 serial interface for trouble-free data transfer.
• Inside cabinet made completely of stainless steel and ex-proof.
• The magnetic sealing system reliably prevents freezing of the door seals.
• Equipped with three inside compartments (high 353 mm), each provided with an insulating door to prevent any loos of cold air.
• Wide range of accessories. Custom-made solutions on request.
• Energy-saving, maintenance-free cooling unit. The refrigerant is non-flammable. The all-around special insulation is up to 150 mm thick. The heat emission is only approx. 400 W.
