Import Electronic Heating Device ( Ptc ) For Heater — Buy in Bulk from Supplier in China

The Electronic Heating Device (PTC) from Shanghai Minkvon Industry Co., Ltd. operates using positive temperature coefficient technology to self-regulate heat output, preventing overheating without external thermostats. It operates at 12V to 24V DC with a rated power range of 15W to 120W, depending on model, and achieves thermal equilibrium within 90 seconds of activation. The casing is constructed from flame-retardant ABS plastic with an IP20 rating for basic dust and splash resistance.

The heating element is composed of barium titanate-based ceramic material, a standard composition for PTC heaters in industrial applications. Typical resistance values range from 10 ohms at room temperature to over 1000 ohms at operating temperature, enabling automatic power reduction as heat rises. These devices are commonly available in flat panel, tubular, or finned configurations to suit mounting constraints in HVAC units, automotive cabin heaters, or small process ovens.

This product is used by manufacturers of space heaters, water dispensers, and industrial drying systems requiring fail-safe thermal control. Buyers typically order in batches of 500 units or more for integration into end products. Packaging is in anti-static foam inserts within corrugated cardboard boxes. Trade terms are typically FOB Shanghai, with lead times of 15 to 25 days after deposit confirmation. Payment is accepted via T/T or L/C, but no minimum order quantity is stated in the listing.

Shanghai Minkvon Industry Co., Ltd. is listed as an imported supplier with harbor trust tier and no recorded response rate or average response time. The supplier address is verified as Floor 6, Building 1, Usst National Science Pudong 201313 Shanghai China. The listing does not disclose company founding date, employee count, export history, or client names. No certifications, production capacity figures, or quality control processes are stated beyond the generic reference to ISO standards in the description.

The company appears to function as a manufacturer or distributor focused on electronic heating components. Its inclusion in the harbor trust tier suggests some level of platform verification for business registration, but no third-party audits or export documentation are referenced. The absence of response metrics indicates limited buyer communication activity on the platform. No claims about R&D, testing facilities, or in-house design capability are provided.
