UFG20 Series

-5 -20°C Laboratory Deep Freezer, Glass door, Upright type
– 2 versions, steel epoxy coated white colour or stainless steel – 4 models with capacities from 530 to 1365 litres – triple layers, glass doors with full-height handle and anti-fog heating f lm – 2 levels for the controls, standard and PRO – internal f tting with open wire shelves and mix-up possibility shelves-drawers – LED internal lighting – forced-air refrigeration – automatic de

Technical characteristics :

  • Structure : upright type, realized in sheet steel epoxy coated white colour both in- and outside or in stainless steel 18/10 AISI 304 both in- and outside. All the internal corners are rounded to make easy any cleaning operations and the internal bottom is tray type to contain spills
  • Insulation : high density (40 Kg/m³) foamed-in-place polyurethane, with a thickness of 75 mm. CFC-free
  • Castors : Nr 4, made in plastic material, 95 mm diameter and swivelling (360°) 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 refrigerator has been positioned
  •  Insulated doors : Nr 2, hinged, side-by-side, made with the same material and insulation as the rest of the structure (sheet steel epoxy coated white colour or stainless steel 18/10 AISI 304 always both in- and outside). The doors are provided with a removable magnetic rubber gaskets in order to grant a perfect hermetic closing and the closing profiles are heated to avoid the gasket frosting. The handles are flush-fitting type so do not increase the size of the refrigerator. The doors are also fitted with a spring loaded automatic closing devices for openings inferior 90° and special door switches that stop the internal ventilation at the door opening (to limit the air cold loss) and light the internal lighting at every opening. Security key locking for the doors (2 keys supplied)
  • Internal equipment : Nr 10 (5 for each door) storage open wire shelves realized in sheet steel with a strong plastic coating (rust-proof material). The shelves are mounted on special anti-tilt stainless steel slides that allows the shelf extraction and they can be easily removed and adjusted in height without the use of any tool. The special internal racking-system allows a great flexibility of the internal fitting with the possibility of interchange and combine both shelves and drawers (drawers optionally available)
  • Shelf dimensions (W x D cm) : 53 x 65
  • Shelf loading capability (Kg) : 35 (with uniformly stored material)
  • Internal lighting  : Nr 2 bulbs, mounted in the bottom part of the control panel (1 above each door), with automatic activation at every door opening through a special switch
  • Control panel “PRO” : located in the top part of the structure (above the door), it is microprocessor operating with soft-touchpads and LCD display, 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 :
  • Large (2 lines writings) LCD display, retro-illuminated white colour with black characters, indicating the appliance working status (compressor functioning, defrosting, alarm running, actual temperature, etc.)
  • Digital temperature adjusting and displaying with an accuracy of 0,5°C
  • Keyboard password protected with automatic locking, to avoid tampering from unauthorized persons
  • Back-up battery, with automatic recharging, granting till 48 hours autonomy for the control panel functioning in case of power failure
  • Visual and acoustic alarm signalling (with automatic resetting) for:

    • high and low temperature with limits programmable from the user
    • door ajar, delayed of 3 minutes to allow the standard operations
    • power failure
    • battery discharged
    • condenser dirty
    • anti-freezing evaporator
    • sensors failure
  • Muting facilities for the acoustic alarms, with continuous warning indication on the display and automatic ring-back after 3 minutes if the alarm situation persists
  • Test facilities for both battery charging status and alarm limits
  • Alarms memory (not deletable) for the last 30 alarm conditions, with the possibility of checking from the display, the alarm condition, when the alarm is started, when it is ended and which is the highest or lowest peak reached from the temperature (if applicable)
  • Events memory with the possibility of checking from the display, defrostings, door openings, relays status, etc.
  • Pt1000 sensors for a better accuracy of the temperature control
  • Internal ventilation setting
  • NO/NC contact to remote the alarm signals
  • RS 485
  • Cooling unit : top mounted, with the condensing unit compounded by Nr 1 hermetic compressors and Nr 1 finned condenser, air cooled through a fan. Also, in the ceiling of the storage chamber, is mounted the finned evaporator with copper pipes, that is housed into a stainless steel cover that incorporate the fan. All the mounted components are industrial grade to grant the maximum reliability
  • Refrigerant : R404a CFC-free
  • Refrigeration : forced-air, through a fan, granting the maximum temperature uniformity and stability inside of the cabinet
  • Defrosting : completely automatic, thermostat controlled. The condensate water is automatically channelled into an heated tray, located in the cabinet backside, for the automatic evaporation of the condensate water
  • Temperature range : infinitely adjustable between -5°C / -25°C
  • Voltage (V/ph/Hz) : 220-230/1/50
  • Plug : Schuko type
  • Breakers : Nr 2 glass cartridge fuses with a rating of 16A, at protection of the appliance
  • Noise level (dB(A)) : ≤ 54
  • Gross capacity (litres) : 1500
  • Net capacit
