GFL Upright Freezer 6483
Microprocessor-controlled, with variable alarm system
Multifunctional operating panel: with clear symbols, secured by key-operated switch. Alarm limits for over- and under-temperatures (0–20 K) as well as alarm suppression values (0–999 min.) can be set individually. Automatic alarm and error reports, input/retrieval of all safety-relevant values: set and actual temperatures, over- and under-temperatures, accumulator capacity and charge status. Additional control and alarm options are individually settable for different user applications.
Safety: 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 interface: for monitoring purposes and data registration via PC.
Cabinet: Ex-proof, made of stainless steel. Three inner compartments with insulated doors to prevent loss of cold air. Each compartment can be separated by a shelf (accessory). Cooling coils blown into the sides ensure direct cooling from all sides, short cooling down time and even temperature distribution throughout the whole cabinet.
Cabinet door: double sealed (one magnetic sealing) and insulated. The magnetic sealing system reliably prevents freezing of the door seals. Door fitted with a safety lock handle. Hinges on the right-hand side.
Housing: made of electrolytically galvanised sheet steel, powder-coated. Four castors (two of them are lockable) ensure easy mobility.
Insulation: seamless and diffusion-tight polyurethane foam on all sides, up to 150 mm thickness.
Refrigeration System: according to the German Accident Prevention Law. Energy-saving, maintenance-free cooling unit. The motor compartment contains the fully hermetic high-capacity compressor, air-cooled condenser, component-tested safety pressure controller (Pressostat) and other control elements, all easily accessible. The heat emission is only approx. 400 W at maximum temperature.
Safety refrigerant: not flammable.

The Chest Freezer is maintenance-free and has the CE and EAC mark.
