PRESTO 85 Process Systems

Category Stirred / Circulating Baths
Manufacturer Julabo
Country of manufacture Germany
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
