Corrosion-Resistant Heating for Chemical Processes
Chemical process industries require heating elements that withstand highly corrosive media, elevated pressures, and continuous operation in demanding environments. Sri Ambika manufactures immersion heaters, circulation heaters, and bobbin heaters in titanium, Incoloy 825, Inconel, and SS 316L sheaths for chemical tanks, reactors, and process vessels.
Heating Challenges
Chemical compatibility of sheath materials with process media
Electrolytic corrosion in electroplating and chemical baths
High-pressure vessel requirements for circulation heaters
ATEX/FLP (explosion-proof) requirements in hazardous zones
Precise low watt density to prevent solution degradation
How We Address Them
Titanium immersion heaters for acid and aggressive chemical baths
SS 316L and Incoloy 825 immersion heaters for alkaline solutions
Bobbin heaters for replaceable element designs in chemical tanks
Circulation heaters for in-line process fluid heating
Explosion-proof flanged immersion heaters for hazardous zones
Recommended Heating Elements
Frequently Asked Questions
Q1What sheath material is recommended for sulphuric acid heating?
Lead-sheathed immersion heaters are standard for concentrated sulphuric acid and HF solutions. For dilute acids, titanium grade 2 or titanium grade 7 is preferred.
Q2Can you supply ATEX-rated heaters for hazardous chemical zones?
Yes. We supply flanged and screw-plug immersion heaters with explosion-proof (FLP) terminal boxes rated for Zone 1 and Zone 2 hazardous area classifications.
Q3What is the watt density recommendation for chemical bath heating?
For most chemical plating baths, a watt density of 0.5 to 1.5 W/cm² is recommended to prevent localised boiling and solution degradation near the element surface.
