Can the circulator be operated in hazardous/electrical, explosion-proof (EEx) areas?
Only specially designed circulators are suitable for operation in hazardous areas. The necessary components—such as EEx-protected driving motor for the circulating pump, electrical heater, operating and control devices—are unsuitable for conventional laboratory circulators because of their size and cost. EEx-protected circulators are therefore usually much larger than laboratory units but also more powerful. It is possible to use laboratory circulators by placing them outside the hazardous area and passing the thermostating liquid through tubing into the hazardous area.
