PRESTO A45 Process System
Overview The A45 air-cooled process circulators can be used flexibly and independently of cooling water supply. They compensate exothermic and endothermic reactions extremely quickly. The A45 and A45t offer very high cooling and heating capacity down to -45 °C. Both systems are air-cooled, the A45t offers increased heating capacity of 12 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 6 kW (or 12 kW on the A45t) Cooling capacity up to 3.5 kW Key Attributes Type Circulating Incubation Yes Refrigeration Yes Temp Range (°C) -45 ... +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) 463 Manufacturer Specifications Model A45 A45t Dimensions 20.9 x 26.2 x 49.6 in. 20.9 x 26.2 x 49.6 in.
