Chromalox MTS-375E2 Temperature Sensor Module

Chromalox MTS-375E2 is a screw-plug immersion heater engineered for direct heating of liquids in industrial vessels. This model delivers 7.5 kW of heat at 208 V and uses stainless steel heating elements, providing corrosion resistance in challenging process environments. The heater is enclosed in a NEMA 7-rated housing, suitable for hazardous-location installations, enabling safe operation in areas where flammable vapors or dust may be present. As part of Chromalox’s MTS screw-plug family, the MTS-375E2 offers a compact, field-serviceable solution that can be removed or replaced with minimal downtime, supporting maintenance workflows common in chemical processing, water treatment, and other process industries. The unit’s direct-immersion design ensures rapid heat transfer to the contained liquid, maximizing efficiency and responsiveness to temperature setpoints. Typical installations leverage 208-volt service and a 7.5 kW load to achieve the desired liquid temperature rise within a given tank volume and heating rate.
