WHR Refrigerated Heating Circulator, -30 °C to +200 °C, 10/18/25 l

The WHR is a precise external circulator with both refrigeration and heating, covering -30 °C to +200 °C with large filling volumes of 10, 18 or 25 l. It works as a temperature control system for reactors, evaporators and viscometers from 5 to 100 l. Three independent systems for cooling, heating and pre-cooling shorten heat-up and cool-down times, while the pump handles internal and external circulation at up to 4 bar with a maximum flow of 20, 40 or 60 l/min. A stainless steel inner bath resists corrosion, stainless steel safety connectors and tubing make filling and draining safe, recessed external nozzles are protected against damage, and heavy-duty impact-resistant castors allow easy repositioning. Digital fuzzy control with a jog dial and an automatic stop at low liquid level round off the unit.
