PRESTO W50 Process System

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)
