The customised laboratory systems from HOF with very high quality are used in many renowned companies and scientific facilities for research purposes and for product and process development. HOF offers the modern systems in compact or split design with a footprint of 0.2 to approx. 2.5 m2. Control, visualisation and technical operation correspond to that of a production system. Transferring the determined process parameters to a production system is made easier and forms the foundation for reliable production. Each HOF laboratory systems consists of a fully functioning basic unit. Individual equipment variants for customised solutions are also available, providing the required flexibility for the task at hand. • Total footprint: 0,22 m2 to 2,5 m2 • Number of shelf sets: 3+1 to 7+1 • Dimensions of shelf sets (mm): 250/300; 420/470; 600/600 • Hydraulic adjustment of shelves • Operating voltage: 400 V/50 Hz • Cooling from +20° C to -50° C ≤ 40min • Heating from -40° C to +20° C ≤ 60 min • Temperature range from -55° C to +80° C (optionally down to -60° C) • Evacuation time from 1000 mbar to 0,1 mbar ≤ 20 min • End vacuum: 5 µbar • Leak rate: < 0,01 mbar*l/s • Ice capacity: 4 - 40 kg • Temperature minimum condenser: ≤ -70° C (optionally ≤ -75° C) • Control: Siemens SPS S7-300 • User interface: HOF Freeze Viewer Professional
