Industrial heaters — for heavy-duty applications

What is an industrial heater

Industrial heaters differ from domestic types in three ways: power (from 5 kW per unit to hundreds of kilowatts in banks), operating conditions (temperature, vibration, aggressive media, explosive atmospheres) and service life (5–10 years of continuous operation versus 2–3 years for domestic grades). These requirements drive entirely different material choices, construction methods and certifications.

In industrial use, a heater rarely operates in an easy "switch on — heat — switch off" cycle. A typical scenario is continuous operation on an extruder where the nozzle temperature is 280 °C and ±5 °C thermal cycling causes mechanical expansion of the body. Or a steam generator with water at 8 bar pressure and 170 °C. Or a plating tank with 10% sulphuric acid, where a standard stainless steel heater dissolves within a month.

TEN-Miass has been supplying industrial heaters since 2010. Among our clients: Gazprom, IKEA, Volgograd International Airport, AHMAD TEA, and hundreds of medium and large manufacturers worldwide.

Materials for industrial applications

In industrial use, standard AISI 304 stainless steel is not always adequate — temperature, chemistry or mechanical load requires specialised alloys and coatings.

• AISI 316L — molybdenum-bearing stainless steel. Resistant to chlorides (seawater, food brines);
• 12X18N10T (321 equivalent) — titanium-stabilised food-grade stainless. For dairies, breweries, pharmaceutical;
• Incoloy 800/825 — nickel alloy, stable to 900 °C. For aluminium casting, steel heat treatment;
• Inconel 600/625 — maximum heat resistance up to 1000 °C. Hardening furnaces, burners;
• Titanium Grade 2 — corrosion resistance in acids. Plating, chemical industry;
• PTFE (Teflon) coating — for concentrated sulphuric acid and other aggressive media;
• Zinc coating — anti-corrosion protection for carbon steel in food industry environments.

Typical industrial applications

Over 15 years we have supplied industrial heaters across dozens of industries. Representative case studies:

1. Electric boiler for district heating — 6 SEV blocks at 30 kW each, AISI 316 stainless, operating in demineralised water;
2. Extruder for food film production — 12 ceramic band heaters 200×80 mm, 2.5 kW each, 380 V, continuous operation at 220–260 °C;
3. 8-cavity injection mould — 48 cartridge heaters Ø 12×80 mm with Type K thermocouples, hot runner calculation for each cavity;
4. Industrial timber drying chamber — bank of finned heaters totalling 45 kW, stainless fin material (humid environment);
5. Chrome electroplating line — titanium heaters with PTFE coating for a 500 L tank at 55 °C;
6. Air curtain on factory gate — 3 heater banks of 12 kW each with finned elements, activated by gate-open sensor;
7. Hydraulic oil tank — SEM 9 kW (oil heater block, carbon steel) with thermowell;
8. Pharmaceutical pasteurisation — 12X18N10T heater with polished surface, SIP-cleanable design;
9. Process bath heating — 5 immersion heaters 6 kW in an 800 L tank with sacrificial magnesium anode.

Special versions

Industrial tasks often require versions beyond the standard construction. We manufacture:

• ATEX / explosion-proof versions — for zones with flammable gases and dust. Reinforced enclosure, IECEx certification;
• With thermowell for sensor — a dedicated tube for fitting a thermocouple or PT100 without media contact;
• With sacrificial magnesium anode — scale protection in hard water; standard for water heaters;
• With anti-vibration mounting — for high-vibration equipment (compressors, crushers);
• With reinforced terminal seal — for subsea and marine applications (IP68);
• Split band heaters — removable without dismantling the machine;
• Multi-zone — separate heating zones with independent control;
• Non-uniform power distribution — to compensate heat losses at nozzle and fitting zones.

How to order an industrial heater

For calculation and production of an industrial heater we need complete information about your process:

• Equipment type (boiler / tank / extruder / dryer / bath / other);
• Heating medium and its parameters (pH, composition, pressure, temperature);
• Required power and duty cycle (continuous / cyclic);
• Supply voltage and phase configuration;
• Mounting interface (drawing, photo, sketch);
• Certification requirements (GOST, IECEx, food-grade).

Engineering consultation is free. Based on your data we propose the optimal construction, select material and calculate power. Lead time 3–5 days from 1 piece. Worldwide shipping via DHL, FedEx, SDEK. 1 year warranty on all products. Regular supply contracts with fixed pricing are available for industrial customers.
