CK-ML Constant Wattage Heating Element
Description
A CK-ML series type heating element is used for freezing protection or to maintain material temperature in the pipelines, vessels and equipment for exposure to temperatures below 260 °C. A series type heating element is supplied as a kit consisting of a heat trace cable, connectors and cold lead cables.
Design
Heating elements are sized to the Customer’s specifications. The scope of supply includes a made-to-order heat cable, with wires for terminal connection and end termination, and a properly sized gland. A gland is needed to connect the cable inside the power box while ensuring adequate tightness for hazardous area applications.
P.O. Details
To place a P.O., please select the item number of the heating element from the Marking table that suits your project specification, and specify the design length (m). E.g., a P.O. for a CK-ML type heating element with a heat trace cable, resistivity = 100 Ω/km and design length = 30 m, @ 230 V, PFA jacketed, should contain the following number: CK-ML/100/1P/30
