Julabo PRESTO W40 Refrigerated Heating Recirculators, -40 to 250°C
Temperature Control System / Process System Reactor temperature control, tests for all kinds of substances or temperature simulation – the PRESTO are made for highly precise temperature control and rapid temperature changes. Highly efficient components allow extremely fast compensation of exothermic and endothermic reactions. Lab users benefit from high flow rates, constant pressure, and a controlled build-up of pump pressure. Permanent internal monitoring and self-lubricating pumps contribute to the new PRESTO’s long service life. The integrated 5.7’’ industrial touch screen displays all important information clearly and concisely enhancing ease of use considerably. Your advantages 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 (Host und Device) Ethernet SD-Card slot RS232 Modbus RS485 (Accessory) Profibus DP (Accessory) Stand-by input Water Cooled Specifications Part Number 9421401 Model Series PRESTO Category Temperature Control Working Temperature Range -40 to 250°C Temperature Control ICC Temperature Stability ±0.01 to ±0.05°C Setting / Display Resolution 0.01°C Integrated Programmer 8x60 steps Temperature Display TFT Touchscreen Heating Capacity 2.7kW Cooling Capacity (Medium:JULABO Thermal | Ethanol) 1.2kW @ 200°C | 1.2kW @ 20°C / 1kW @ 0°C / 0.55kW @ -20°C / 0.3kW @ -30°C / 0.07kW @ -40°C Pump Capacity Flow Rate 16 to 40 l/min Pump Capacity Flow Pressure 0.3 to 1.7 bar Pump Connections M24x1.5 Refrigerant Stage 1 R507 Filling Volume Refrigerant Stage 1 380 g Global Warming Potential for R507 3985 Carbon Dioxide Equivalent Stage 1 1.514 t External Pt100 Sensor Connection Integrated Digital Interfaces RS232 SD memory card USB Ethernet Modbus Alarm-out Optional: RS485, Profibus Analog Connection Input / Output Optional Ambient Temperature 5 to 40°C Dimensions W x L x H 33 x 59 x 67 cm Weight 78 kg Sound Pressure Level (distance 1 m) Max. 53 dBA Process Volume Min.
