With their robust construction and design, these freezers are the ideal choice for long-term storage of your most sensitive materials.• Structure : upright type, realized in sheet steel painted white colour (rust- and corrosion-proof) outside and stainless steel 18/10 AISI 304 inside• Insulation : injected polyurethane a high density, with a thickness of 130 mm. CFC-free• Casters : Nr 4 made in rubber and swivelling in order to make easy any moving required. The castors mounted in the front side are fitted up with brakes with foot lever control to block them once the freezer has been positioned• Door : Nr 1, hinged, fully insulated, externally it is executed in the same material of the structure (sheet steel painted white colour) while internally it has non-conductive material. A perfect hermetic closing is assured through a double gasket system, one, magnetic mounted on the door itself and another one, silicone type, mounted on the structure of the freezer. The gaskets are even provided with a special heating system to prevent the freezing and thanks to the vacuum-release valve the door can be immediately re-opened a closing. In the right part of the door is mounted the effort-free locking mechanism which incorporate the safety key lock• Inner doors : Nr 2, hinged, realized in stainless steel 18/10 AISI 304 in the external side and non-conductive material in the internal one. The inner doors prevent air-cold loss at the external door opening and they are also provided with a locking mechanism with a lever • Internal equipment : Nr 3 storage shelves realized stainless steel 18/10 AISI 304 that divides the storage chamber in 4 compartments with dimensions (W x D x H) 45 x 45 x 27 cm each. The shelves are mounted on brackets and they can be easily adjusted in height or removed without the use of any tool. • Shelf dimensions (W x D): 45 x 45 cm• Control panel “PRO2” : located in the bottom part of the structure (under the door) is microprocessor operating with soft touch-pads, LED display and warning lamps, allowing the control of all the functions and working status of the freezer (including alarms). The control panel is battery operating in order to grant the functioning of the alarms even in case of power failure. The main functions of the control panel are : • Digital temperature adjusting and displaying with an accuracy of 0,5°C • Warning lamp signalling when the cooling unit is ON• Keyboard block with a password to avoid tampering from unauthorized persons • Visual and acoustic alarm for high or low temperature with programmable limits • Visual and acoustic alarm for door ajar, delayed of 30 seconds to allow the standard operations• Visual and acoustic alarm for power failure • Visual and acoustic alarm for dirty condenser that limit the cooling unit performances• Visual alarm for discharged battery with the possibility to display the charging status• Temporally muting of the acoustic alarms, with automatic re-activation in case the alarm conditions continues• NO/NC contact• RS 485• Cooling unit : bottom mounted, compounded by Nr 2 hermetic compressors (cascade) with a power of 0,625 HP each, Nr 1 finned condenser, air cooled through a fan and special electro-valves. The cooling unit compartment is adequately acoustically insulated to limit the noise level. Also, foamed into the insulation of all storage chamber walls, there are the evaporating pipes, in order to grant the maximum temperature stability and uniformity. All the mounted components are industrial grade to grant the maximum reliability• Refrigerant : CFC-free • Refrigeration : static, with evaporating pipes throughout all the chamber in order to grant maximum temperature stability and uniformity• Temperature range : infinitely adjustable between -60°C / -86°C• Voltage (V/ph/Hz) : 220-230/1/50• Plug : Schuko type• Noise level (dB(A)) : 52• Capacity (litres) : 240
