PRESTO W50 Process System

Category Stirred / Circulating Baths
Manufacturer Julabo
Country of manufacture Germany
Overview

The rapid compensation of reactions even at higher ambient temperatures is the domain of the water-cooled W50 units. High heating and cooling capacity paired with powerful pumps. Both systems are water-cooled, the W50t offers increased heating capacity of 10 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)
  • Pump pressure up to 3.2 bar, max. flow rate 76 l/min
  • Second external Pt100 sensor connection (accessory)
  • Temperature stability ±0.05 °C ... ±0.1 °C
  • Heating capacity up to 5.4 kW (or 10 kW on the W50t)
