PRESTO 80 Process System
Overview 2-stage process circulators for low temperatures. As air- or water-cooled versions, the A80 and W80 units with 2-stage refrigeration unit offer high cooling and heating capacities for lowest temperatures down to -80 °C. The "t" model offers increased heating capacity of 3.1 kW. Features: For highly precise, external temperature applications Rapid heating and cooling Wide working temperature ranges without changing fluids Highest performance with small footprint Space-saving design optimizes space utilization in your lab 5,7” industrial color TFT touch screen USB connection Ethernet SD-Card slot RS232 Modbus RS485 (Accessory) Profibus DP (Accessory) Removable ventilation grid Heating capacity up to 1.5 kW (or 3.1 kW on the A80t and W80t) Cooling capacity up to 1.2 kW Key Attributes Type Circulating Incubation Yes Refrigeration Yes Temp Range (°C) -80 ... +250°C Capacity (L) N/A Circulation External Only Brand Julabo MaxFlow Rate (l/min) 76 Temp Stability (°C) ±0.01 to 0.05°C Timer Yes Alarms Yes Digital or Mechanical Digital Data connection Yes Tank Material N/A Sample Agitation No Media Racks Available No Warranty (years) 1 Weight (lb) 368 Manufacturer Specifications Model A80 A80t W80 W80t Dimensions 16.9 x 25.6 x 49.6 in. 16.9 x 25.6 x 49.6 in. 16.9 x 25.6 x 49.6 in. 16.9 x 25.6 x 49.6 in.
