CK-MI-1M Open Platform Cable Heat Tracing
Description
A CK-MI-1M mineral-insulated constant wattage heating element is used for freezing protection or to maintain material temperature in the pipelines, vessels and equipment for exposure to temperatures below 850°C.
A mineral-insulated constant wattage heating element is supplied as a kit consisting of a heat trace cable, cold tails, a connection kit and cold lead cables.
Design
Heating element is sized to the Customer’s specifications. The scope of supply includes a made-to-order heat cable, with a brazed cold lead connector and a cold lead cable for junction box connection, and properly sized brass glands. A gland is used to connect the cable into the power box while ensuring adequate tightness for hazardous area applications.
P.O. Details
E.g., a P.O. for a CK-MI.1M type heating element with a heat trace cable, stainless steel jacketed, resistivity = 2500 Ω/km and design length = 54 m, @ 230 V operating voltage, 2.5 sq.mm and 1.5 m long cold tail, should contain the following number: CK-MI-1M.S/2500/54/230/CL2.5-1.5
