ACR
Forced Air
Freezer Chest

The freezer chest with forced air circulation have their specific field of application in the pre-thermostatisation of
some Systems of Finish, Fast Freezing of Liquid Substances and Studies of Thermal Stress in the fields of Building Materials, Plastics and Rubbers.
Their main advantage in front of the Freezers with Static Evaporation is, besides their design of the Air Circulation, the
fast velocity of cooling and temperature recovering.
Capacity from 150 liters to 5000 liters and range of temperature from ambiance to -70ºC.

• Different volumes
• High temperature rate of change
• Easy to install and easy to use
• Reliable construction
• Long life
Construction

The  construction is extremely  strong  and suitable  for the function they must do, in order to ensure a long life of the Equipment.

• Inside in AISI 304 stainless steel. Outside in painted steel,  according to RAL-9010.
   Painted door, according to RAL 7011.
• Depending on the model, the opening of the door can be done by  pneumatic cylinders or pneumatic springs.
• 4 multidirectional castor wheels, multidirectional, to facilitate the mobility.
• Electrical panel located on the side of the freezer, properly insulated and protected.
Options

• Digital paperless recorder.
• Acoustic alarm of end of process.
• RS-232 port for connection to PC, programming Software and data acquisition in Windows environ- ment.
• Output to terminals 4/20mA or 0/10V.
• Port made of Teflon with watertight bin (different diameters).

Vertical Freezer


Forced Air circulation
• Volumes from 81 to 2000 liters
• Temperature range from -40ºC or -70ºC
• Higher ergonomic
• 2 Shelves
• Special designs

The vertical freezers have the same technical characteristics of the ACR, but with the particularity of their design that make the introduction and the extraction of samples easier.

They occupy less surface than the horizontal ones, this is a big advantage when the space of the Laboratories is not enough.

Possibility to make the doors with a small observation window and glass-doors with metallic doorcase. Its is possible to make a freezer with a double compartment with independent regulation.
Their vertical design allows the use of lots of sample cradle.
