    Beskrivning

    The range of flameproof mini line heaters consist of a screw plug or flanged type immersion heater mounted in a thermally insulated heating vessel, and is designed to efficiently transfer heat to a flowing medium (liquid, air or gas). The FP-MLH range is certified for use in hazardous areas where the atmosphere is classified as a Zone 1 or 2 (IIA, IIB, IIC) gas group.

    Features

    • Weatherproof protected to IP66 or NEMA 4 (FP4-MLH only)
    • Choice of built in process temperature sensors and externally adjustable option
    • Mild steel or 316 stainless steel vessel
    • Suitable for ambient temperatures from -40°C to +40°C (FP-MLH) and -60°C to +60°C (FP4-MLH)
    • Standard range of high quality Incoloy or stainless steel rod-type elements, designed for water or withdrawable ceramic core elements, designed for oil
    • Maximum allowable working pressure up to 10 barg / 145 psig, subject to design parameters
