PRESTO W55 Process System

Overview

The powerful W55 regulates temperatures with high precision and convinces with faster cool-down and heat-up times. It is ideal for use in large external applications such as reactor temperature control, material stress testing or temperature simulation.

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
• Temperature stability ±0.05 °C ... ±0.1 °C
• Second external Pt100 sensor connection (accessory)
