What can be done to avoid fumes emitted by circulating liquids?
Unfortunately, the fumes emitted from circulating liquids are unavoidable. There are a number of steps that can be taken to contain the odor. A covered bath is recommended; when an open bath is required, an exhaust fan at the liquid surface can minimize fumes. When possible, circulators should be placed in a fume hood. If a thermostat is required solely for circulation and operates continuously at high temperatures, it is advisable to use the high-temperature thermostat USH-400, specially designed to contain emissions.
