PRESTO 85 Process Systems

Overview Powerhouses among the process circulators. High cooling capacities enable extremely low temperatures down to -85 °C possible. The high heating capacity, particularly with the A85t and the W85t, provides even more flexibility in the application. 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 15 kW Pump pressure up to 3.2 bar, max. flow rate 80 l/min Heating capacity up to 1.5 kW (or 3.1 kW on the A85t and W85t) Cooling capacity up to 2.8 kW Key Attributes  Type Circulating Incubation Yes Refrigeration Yes Temp Range (°C) -85 ... +250°C Capacity (L) N/A Circulation External Only Brand Julabo MaxFlow Rate (l/min) 80 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) 804   Manufacturer Specifications Model A85 A85t W85 W85t Dimensions 24 x 42.5 x 49.2 in. 24 x 42.5 x 49.2 in. 24 x 33.3 x 49.2 in. 24 x 33.3 x 49.2 in.
