Import Explosionproof Heating Mantle — Buy in Bulk from Supplier in India

The explosionproof heating mantle from N.K.Joshi & Co. is a laboratory-grade heating device designed for use in hazardous environments where flammable vapours or dust may be present. It features a flameproof enclosure that prevents internal sparks or heat from igniting external atmospheres, meeting the basic requirements of IEC 60079-1 for explosive atmospheres. The unit supports temperature control within a range of ambient to 300°C, with a standard power input of 230V AC and adjustable thermostatic regulation for consistent heat distribution across glassware surfaces.

The heating element is encased in a non-sparking, high-temperature ceramic insulation layer, with a stainless steel outer shell resistant to chemical corrosion. The mantle is compatible with round-bottom flasks from 100 mL to 5 L, with a flexible clamp system for secure mounting. While the supplier does not specify exact certification codes, the design follows standard industrial practices for Class I, Division 2 hazardous locations commonly found in pharmaceutical and chemical synthesis labs. Typical insulation materials include fiberglass or ceramic wool, and the housing is rated for continuous operation under 24-hour cycles.

This device is primarily purchased by research laboratories, pilot plant operators, and quality control departments in the pharmaceutical and fine chemical industries. Buyers often require it for distillation, reflux, and solvent recovery processes where open flames are prohibited. Trade terms are typically FOB Mumbai or CIF port of destination, with minimum order quantities generally starting at one unit for standard models. Lead time is usually 2 to 4 weeks after order confirmation, pending availability of components. Buyers should request a copy of the manufacturer’s test report for flameproof integrity before shipment.

N.K.Joshi & Co. operates from Panvel, Maharashtra, India, and is listed as an imported supplier with harbor trust tier verification. The company does not publish its years in business, workforce size, or annual turnover. Its listing confirms direct export capability and physical presence at its registered industrial address, but provides no details on production capacity, client list, or internal quality control procedures. The absence of response rate or average response time suggests limited real-time communication channels.

The supplier appears to source or assemble explosionproof heating mantles for export, likely sourcing components locally and assembling units to meet international safety norms. There is no mention of in-house testing facilities, certifications, or ISO accreditation. Buyers should treat all technical claims as unverified unless confirmed with the supplier directly. The company does not appear to offer custom engineering or OEM services based on available data.
