Chest and Upright Freezers with Natural Coolants
The GFL hydrocarbon green freezers implement the current Kyoto Protocol guidelines which call for a considerable reduction of greenhouse gas emissions. Applying climate-neutral hydrocarbons with an extremely low global warming potential (GWP), the freezers contribute effectively to reducing the greenhouse effect in the atmosphere.
Upright freezer with natural coolants, microprocessor-controlled, with variable alarm system and potential-free contact for connection to an internal alarm system.
Multifunctional operating panel:
With clear symbols. Alarm limits for over- and under-temperatures as well as alarm suppression values (up to 240 min) can be set individually. Automatic alarm and error reports, in-put / retrieval of all safety-relevant values: set and actual temperatures, over- and under-temperatures.
Maintains all display and alarm functions for 48 h 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.
Acc. to BG-I 850-0, version 02 / 2009, made of st. steel. Upright freezers 6641 and 6681 (sub-counter deep freezer): 3 drawers, running smoothly on rollers, with insulated doors to prevent loss of cold air (inner height 155, 160 and 165 mm). Upright freezers 6643, 6645, 6683 and 6685: 3 inner compartments with insulated doors to prevent loss of cold air. Upright freezers 6647 and 6687: 5 inner compartments with insulated doors to prevent loss of cold air, with height- adjustable perforated intermediate shelves. Each compartment can be separated by a shelf (accessory). Chest freezers 6540, 6545, 6580, 6582, 6583, 6584 and 6585: additionally insulated with removable covers to prevent loss of cold air. Cooling coils blown into the sides ensure direct cooling from all sides, short cooling down time and even temperature distribution throughout the whole cabinet. Freezers 6545, 6582, 6583, 6584 and 6585: removable insulated cover plate to prevent loss of cold air.
Cabinet lid / door:
Double sealed (one magnetic sealing) and insulated. The magnetic sealing system reliably prevents freezing of the lid / door seals. Door fitted with a safety lock handle. Hinges on the right-hand side. Chest freezers 6540, 6545, 6580, 6582, 6583, 6584 and 6585: fitted with counter-balanced spring tension hinges.
Made of electrolytically galvanised sheet steel, powder-coated, widely resistant to acids bases and heat. Upright freezer 6641 and 6681 (sub-counter freezer): 4 castors. Upright freezers 6643, 6645, 6647, 6683, 6685 und 6687: 4 castors (2 of them are lockable) ensure easy mobility on different sites. Chest freezers 6540 and 6580 with 4 castors, 6545, 6582, 6583, 6584 and 6585 with 6 castors (2 of them are lockable).
Seamless and diffusion-tight polyurethane foam on all sides, up to 150 mm thickness. 6647 and 6687: vacuum-isolated panel with impermeable polyurethane foam.
According to the German Accident Prevention Law. Energy-saving, maintenance-free cooling unit. The motor compartment contains the fully hermetic high-capacity compressors, air-cooled condenser, component-tested safety pressure controllers (Pressostat) and other control elements, all easily accessible.
Natural coolants - hydrocarbons.
