About NC Heater

NC Heater in use

A variety of high-temperature heaters using hot air. Stable control of hot air temperature from room temperature up to 800°C. Odorless and pollution-free clean heat source. Quick temperature rise, easy to control.

Various controllers available: flow meters, pressure gauges, temperature controllers, and more.

We will assist you in testing before installation to help select the most suitable heater for your operation.

Custom manufacturing available: special casing, voltage changes, air intake position changes, thermocouple specifications, etc.

Nickel wire heating element available for semiconductor manufacturing where copper contamination must be avoided.

NC Heater Applications

  • · Soldering of surface mount parts
  • · Heat source for heat shrink tubing
  • · Heat source for caulking of thermoplastic resin
  • · Preheating of cans before printing
  • · Linear heating of coreless coils on winding machines
  • · Heat drying of adhesives
  • · Silver brazing of medical device parts
  • · Heating of liquids

Wattage Selection Formula

Use the formula below to estimate the required heater wattage based on your air flow rate and target temperature:

Constant (0.02) × Flow rate (L/min) × Temperature (°C) ÷ Thermal efficiency = Power (W)
* Constant varies by temperature; use 0.02 as a reference value for heater capacity estimation.

⚠️ Important Precautions

■ Air / Gas piping
Prior to use, depressurize the air/gas piping system (including cylinders) to secure proper flow rate control.

■ Power supply voltage
When using rated voltage, no voltage regulator is needed — but be sure to maintain the minimum flow rate. In general, use a voltage regulator to adjust temperature.

■ Usage precautions
· Use air or inert gas only (N₂, Ar, etc.) — never use flammable gas.
· When using a compressor, always filter out oil and water.
· Always follow the sequence: Fluid ON → Power ON → Power OFF → Fluid OFF
· Minimum flow rate varies by model (e.g. 15L/min or more at 100V-350W). Verify before use at low flow rates.
