Air heating, evaporator defrost and straight rods – built to your length, rating, cold zone and connection.
Finned · defrost · straight rod
Finned elements carry the same power at a far lower sheath temperature; defrost heaters keep evaporators clear at 1 – 3 W/cm². Straight rods come in cut lengths with cold ends, ready for your own heaters.
We build all three to your rating, length, cold zone, sheath material and connection – for HVAC and ventilation, heat pumps, refrigeration, drying and industrial equipment.

Applications · where they work
Defrost heaters on evaporators, finned air heaters in units and ducts, straight rods for your own heaters and sauna stoves.
Key specifications
Typical series values from our specifications master. Individual designs can sit outside them when the application justifies it.
| Parameter | Typical series value |
|---|---|
| Sheath diameter | 8.0 – 16 mm tube; fin outer diameter approx. 24 – 36 mm (finned); 6.5 – 8.5 mm (defrost); 6.5 – 16 mm (straight rod) |
| Sheath materials | AISI 304, AISI 321, Incoloy 800; fins in aluminium, galvanised steel or stainless steel; defrost in AISI 304 or copper |
| Fin geometry (finned) | Helically wound fin, height ≈ 8 – 10 mm, pitch ≈ 4 – 6 mm, thickness 0.4 – 0.6 mm; galvanised or aluzinc steel fins for low-temperature air, stainless steel fins (AISI 304) for higher temperatures – max. temperature depends on fin material and air velocity, confirmed per project |
| Power range | Finned 300 – 3000 W; defrost 100 – 800 W; straight rod 200 – 5000 W |
| Voltage | 115 / 230 / 400 V; low-voltage variants (12 – 48 V) for defrost on request |
| Watt density | Finned 2 – 4 W/cm² on the tube; defrost 1 – 3 W/cm²; straight rod per application medium |
| Terminal types | M4 / M5 studs, 6.3 mm tabs, lead wires with silicone or PTFE insulation and strain relief, plug connectors on defrost heaters |
| Sealing options | Silicone resin, epoxy resin (defrost, moisture-critical), PTFE bead, ceramic bead for high-temperature finned heaters |
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
Every form is built to drawing – length, cold zone, connection and fixing to your coil, duct or frame.
Air heating
The fin multiplies the air-side surface, so a large volume of air is heated quickly and evenly at a low sheath temperature.
Refrigeration
Low-load elements fitted to evaporators in refrigerators, freezers, cold rooms and heat pumps, often with a bare section through the drip tray.
General purpose
The basic building block for industrial heaters, supplied in standard lengths for your own assembly – annealed, so they can still be formed after delivery.
Technical drawing · three types
The fin spreads the heat of the tube over a far larger air-side surface, so the sheath runs cooler at the same load.
Design considerations
Material, surface load, sealing and the standard of the finished appliance – settled on the drawing, confirmed in our laboratory.
AISI 304, AISI 321 or Incoloy 800, chosen by sheath temperature. Stainless fins where the air is humid or corrosive; defrost sheaths in AISI 304 or copper.
Set by the medium, the air flow and the allowed sheath temperature – finned elements with aluminium or galvanised fins are designed for about 350 °C sheath temperature at most; stainless fins on AISI 321 or Incoloy 800 allow more. The final value is validated in our laboratory.
Defrost and heat-pump heaters can idle for months in cold, wet air; moisture taken up by the MgO then lowers insulation resistance. Epoxy-resin seals, protected connections and the cold zone decide.
Typical for the finished appliance: EN 60335-2-30 (room heaters), 2-24 (refrigerating appliances), 2-40 (heat pumps); CE, RoHS, REACH. Marks are obtained per project; our approvals are listed under certificates.
Validation
Finned, defrost and rod elements are checked for fin bond, cold-end length and terminal tightness on samples, and every series element passes a 100 % electrical test.
Samples go through humidity storage followed by insulation resistance and leakage current, corrosion and salt spray, heating uniformity, cold-zone verification and a life test in our validation laboratory. Every element passes the 100 % series test before packing.
The complete test programme: Quality and validation laboratory.
