Way back in 1930, Kantilal Doshi, one of Bombay’s brightest electrical professionals, created a Spherical Water Heater. From this we had born THE SPHEREHOT GROUP.

Mr. Kantilal Doshi was then one of the best electrical contractors in Bombay. He saw the need for electrical heating appliances and water heaters & produces for the first time in the country a range of domestic appliances.

But that was just the beginning. As a result of Mr. Kantilal Doshi’s pioneering efforts, and the Industrial Development in post independent India, there was a gradual development of locally manufactured components that aimed at providing import substitutes. The latest addition was the high temperature and corrosion resist nickel based alloy tubes required for heating elements.

As the years went by, the pioneering efforts of Mr. Doshi began to bear fruit. In 1958, from a small workshop in Bombay the manufacturing operations were shifted to Udhna, Surat, about 250 KM away from Bombay. And Kantilal Chunilal & Sons Appliances Pvt. Ltd. was set up at a substantial investment for the manufacturing of electrical parts for the electrical storage type water heaters.

In 1963 Spherehot took a giant step forward and set up Doshi Metal Industries, the first plant to manufacture tubular sheathed heating elements in India. The name Doshi Metal Industrial was later converted to Doshi Heaters Pvt. Ltd. so the activity speaks the name.

The manufacturing of tubular sheathed heating elements in India for the first time revolutionalised the concept of electrical heating and new avenues for further expansion and diversification were opened. There was a change in emphasis from domestic heating. And to cater to the need of the hour, the latest machines were procured for the production of tubular heaters.

In 1983, Spherehot diversified into the manufacture of high temperature and corrosion resistant alloy tubes and set up another unit by name of Doshi Tubes Pvt. Ltd. This unit housed latest tube welding mill from U.S.A which is specially designed for the manufacture of seam welded tubes from various grades of nickel based alloy strips. Doshi Tubes Pvt. Ltd. is now on the threshold of further expansion of it’s product line to meet the ever growing requirements of heat exchanger, condensing, Feed Water Heating systems, etc. required by the manufacturers of Power Generation Plants.

During production, quality control is not a random check but a regular and continuous process. As a part of the quality assurance programme, and as required by the Bureau of Indian Standards, testing laboratories with the latest facilities have been established at the manufacturing units. All raw materials, sub assemblies and completed products meet self-imposed as well as BIS Specifications and receive the ISI Certification mark wherever applicable.

When it comes to on site and Custom built projects, the Group’s trained experts personally supervise every job.

Products which are custom built or exported meet the stringent requirements of Lloyds Register, Bureau Veritas, Defence Establishments, The Atomic Energy Establishment, the Export Inspection Agency, mew/nha Kuwait, SGS India Pvt. Ltd. and various other inspection agencies.

This quality assurance has enabled the group to enter into a number of collaborations with American and French manufacturers and to undertake projects for Bharat Heavy Plate & Vessel Limited, Visakhapatnam and Hindustan Aeronautics Limited, Lucknow.
