Built around a self-regulating polymer core, the cable automatically varies its heat output along its entire length in response to ambient temperature changes. This behavior eliminates hot spots and reduces energy consumption compared to constant-wattage alternatives. The parallel circuit construction allows the cable to be cut to length at any point without affecting performance, making field installation straightforward for mechanical and electrical contractors.\u003c\/p\u003e\u003cp\u003eThe STW51-24P is suited for use on metal and plastic pipes in commercial construction, institutional buildings, and select industrial freeze protection scenarios. It is appropriate where a flexible, field-cuttable heat trace solution is needed without the constraints of zone or series wiring configurations. The cable can be single-overlapped on the pipe without risk of overheating, which is useful when routing around fittings, valves, and irregular pipe geometries. Licensed electricians and mechanical contractors typically specify and install this product as part of a complete pipe freeze protection system.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSelf-regulating polymer core automatically adjusts heat output based on surrounding temperature, preventing hot spots\u003c\/li\u003e\n\u003cli\u003eParallel circuit construction allows cutting to any length in the field without special termination limitations\u003c\/li\u003e\n\u003cli\u003eSafe for single-overlap installation on pipe without overheating risk\u003c\/li\u003e\n\u003cli\u003eCompatible with both metal and plastic pipe types\u003c\/li\u003e\n\u003cli\u003eSuited for commercial construction, institutional, and light industrial freeze protection applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThe STW51-24P has been identified as a possible alternative or replacement for models FG1-24P, FG1-36P, PSR1024, and ORF-P-024 from other heat trace cable manufacturers. Customer must independently confirm compatibility with their specific application before installation. CHROMALOX is not an authorized distributor for those referenced brands.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of heat trace cable should be performed by a licensed electrician in accordance with NEC Article 427 and applicable local codes. De-energize and lock out all circuits before handling existing trace cable or electrical connections. Follow the manufacturer's installation guide for end seal, splice, and power connection kit selection appropriate to the exposure rating and circuit voltage. Do not energize the cable before insulation and jacketing are properly secured.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable Type\u003c\/strong\u003e: Self-Regulating Heat Trace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: Parallel circuit, polymer self-regulating core\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Freeze protection for metal and plastic pipes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CHROMALOX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: STW51-24P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHROMALOX","offers":[{"title":"Default Title","offer_id":51672641667378,"sku":"STW51-24P","price":131.93,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/SRL-Cable-e1550346196487-150x150_14ce45e3-4c7c-45df-be08-c38daa6f5bc1.jpg?v=1787970208","url":"https:\/\/voomisupply.com\/products\/chromalox-stw51-24p-self-regulating-heat-trace-cable","provider":"Voomi Supply","version":"1.0","type":"link"}
