Industrial Equipment

Elements for machines where downtime is counted in production hours.

Sauna heaters, HVAC and ventilation duct heaters, air curtains, drying cabinets, industrial washers and process tanks. Here the fitting and frame design is often as important as the element itself.

Every inquiry starts with the medium, temperature, power and installation space. Our proposal states the watt density and sheath material explicitly, so you can check it against your own process knowledge.

Key specifications

Wide specifications, stated in one table.

Typical series values from our specifications master. Individual designs can sit outside them when the application justifies it.

Watt density is on the heated sheath. Values are typical; the final design is confirmed by BALÇIK TORMEC engineering. All product groups: Specifications by product group.

Typical forms

Three constructions cover most machines.

The medium and the duty cycle decide the design – from small-series specials to recurring series.

Sauna heater element, catalogue part 92706

Still air

Sauna heater rods

Straight and hairpin rods at visible red heat behind stones – the extreme of still-air duty, with Incoloy 800 sheath and long cold zones through the heater floor.

  • Typically 1500 – 3000 W per sauna element
  • Ceramic bead and cement seal
Spiral-finned air-heating elements for duct heaters

Forced air

Duct-heater elements in frames

Plain or finned elements in frames with flange plates and airflow interlocks – for HVAC and ventilation, air curtains and drying cabinets.

  • Duct and process assemblies 3 – 60 kW
  • Terminal boxes IP54 / IP65
Immersion heater with brass hex head for process tanks, render

Process liquids

Process-tank immersion heaters

"U" and "W" immersion heaters for industrial washers and process tanks, on round flanges or threaded nipples.

  • 12 – 16 mm process tanks
  • AISI 316L for process liquids
Also built to drawing: elements for commercial laundry (oval flanges, integrated thermal fuse for the steam boiler and the wash tub), dry-cleaning machines (sheath and surface load chosen for the solvent), ironers and presses (flat tubular elements fixed on flatwork-ironer cylinders), floor-cleaning machines (high specific power for small water volumes under pressure); spa and body-care devices that vaporise water or scented liquids, heaters that hold the water temperature in jacuzzi and spa bathtubs, and enclosed steam generators for steam cabins.

Technical drawing · three constructions

Sauna rod, air spiral, process-tank heater.

Rods heat the air of saunas, dryers and ovens, flat spirals sit in ducts and ventilation units, and screw-plug or flanged heaters work in process tanks – each drawn for its medium and surface load.

Design considerations

Specify the medium and the site, not just the power.

Industrial elements run for thousands of hours a year, often at full load – material, surface load and terminal protection decide whether the installation is maintenance-free.

Materials

AISI 304 and 321 for air, Incoloy 800 for saunas and high-temperature air, AISI 316L for process liquids. Chemically loaded baths need the sheath stated on the drawing, never assumed.

Watt density on the heated sheath

Water, oil, glycol, alkaline baths, still or moving air and metal contact each set their own ceiling. An element that is right for one medium can be wrong – sometimes dangerously – for the next.

Sealing and terminal protection

Terminal boxes face washdown, condensation, dust, vibration and ambient temperatures from freezer rooms to foundries. Ingress protection, terminal insulation and cable entry are specified, not assumed.

Equipment standards

Typical for the finished equipment: EN 60335-2-53 (sauna heaters), 2-30 (room heaters), 2-40 (heat pumps and air conditioners); EN 60519 / IEC 60519 for industrial electroheating; VDE for approved element families; RoHS, REACH; CE marking of the finished appliance.

Validation and documentation: every element passes the 100 % series test – resistance, dielectric strength and insulation resistance. Series parts are validated with leakage current, corrosion and salt spray, heating uniformity and a life test; small series ship with a drawing for approval, a material certificate and a test report. How we test – quality and laboratory

Validation

Tested before it reaches your machine.

Samples are validated in our laboratory for your medium and duty; in series, every element passes a 100 % electrical test – traceable back to the raw-material lot.

The complete test programme: Quality and validation laboratory.

  • 100 % electrical test of every series element – high-voltage dielectric strength, insulation resistance and resistance/power check.
  • Leakage current at rated power input, hot and cold.
  • Dimensional and terminal checks on formed and finned parts.
  • Life tests on samples at rated power before series release.
