Engineering capabilities

Engineered to the duty, not picked from a catalogue.

Requirements arrive as an application, a drawing or an existing part. Our engineering team works from any of these to a defined specification.

Why Isotherm

Heating, control and insulation from one supplier.

In-house manufacturing & testing

Designed, built and tested in our own Hyderabad facility — drawing to dispatch, under one roof.

Built to your specification

Custom voltage, wattage, dimensions, sheath and construction. Send a drawing or an existing sample, and we engineer to it — prototype through production quantities.

Quality system

An ISO 9001:2015-certified company, engineering since 1989. CE marking and RoHS compliance apply where they are applicable to the product and order.

Responsive engineering support

Responsive engineering and commercial support, with export-ready packaging where required.

Inside Isotherm

Designed, built and tested in Hyderabad.

Element winding, flexible-heater manufacturing, assembly, control-panel production and electrical testing are carried out in our own facility — which is how a drawing or a sample becomes a finished, tested heater.

Engineering applications

Problem, approach, solution.

Typical enquiries start from a problem on a plant rather than a part number — a line that will not hold temperature, a jacket that cannot be refitted after a shutdown, an obsolete heater with no drawing.

Not sure which heater you need?

Tell us what you need to heat, the required temperature, size/dimensions and available power supply. Our team will recommend the suitable heater type.

Request a quote

Tell us what you need to heat.

Send your requirement — a drawing, a spec, or the old part — and our engineers will come back with sizing, materials and pricing, usually within 24–48 hours.

For a faster quote, share any details you have: application, dimensions, wattage, voltage, target temperature, quantity, operating environment and drawings/specifications.

Optional — the more you share, the faster your quote
PDF, JPG, PNG, DWG, DXF, STEP, Office documents or a ZIP. A photograph of the existing part is enough to start.

No drawing? Send us your existing heater or a sample. Our engineering team can evaluate it and propose a suitable replacement, subject to technical feasibility.

Request sent
