Process thermostat PRO RP 290 E

compactdigitalelectronic

Overview
The PRO RP 290 E circulation and process thermostat is designed for external industrial applications requiring rapid thermal response and flexible cooling. Compact tower design with low filling volume enables fast heating/cooling cycles. Integrated hybrid cooling (air and water) and a pressure-suction pump are fitted as standard.

Features

• Microprocessor-controlled thermostatic circulator with integrated cooling system
• Operation via cursor and softkeys; detachable command console for remote use
• Stainless steel bath vessel (insulated, with overflow and drain tap)
• Retrofittable interfaces: RS‑232/485, Profibus, EtherCAT, analogue or contact modules
• Adjustable low-level and over-temperature protection with acoustic alarm for use with flammable and non‑flammable liquids
• Uses natural refrigerants and low filling volumes for fast thermal response
• Bright high-contrast OLED display and EasyUse system for simplified operation
• LAUDA Varioflex pump (pressure/suction) with 8 selectable levels; rear connections
• Fully electronic continuous controller with PID action for internal and external control
• SmartCool digital cooling management with compressor on/off control for energy efficiency
• Integrated programmer: 1 programme with up to 20 segments; SelfCheck Assistant for diagnostics
• USB and Ethernet interfaces; PowerAdapt system to maximize available power usage
