| Controller for hot air heater Explanation of FCM | |
| Summary FCM is a dedicated controller for SAH, SAHD type hot air heater, it is simple to connect and can control both air and hot air temperature. Basically, with just this 1 unit, it is possible to use the hot air heater freely and safely without worrying about the air control. |

FCM-N  |
It can continuously generate a stable supply of hot air. In the normal air heaters, the heaters are used by setting the air flow rate and then setting the hot air temperature. However, in FCM-N type, the controller automatically determines the air flow rate. First set the heater output (% of heat quantity), and then set the hot air temperature to use the unit. The major feature of this unit is that the thermal output is constant without being impacted by the large errors and variations in the temperature sensor. When you do not want to lower the hot air temperature, but want to lower amount of heat (air volume), the output is lowered. On the other hand, when you want to maintain the same hot air temperature and increase the amount of heat (air volume), the output is increased. If the amount of heat (air volume) is insufficient even when increased to 100%, it indicates that the heater capacity is insufficient, and has to be changed to a heater of one rank higher capacity (electric power). When the SAHD heater is used at high temperatures in the range 1562ºF (850ºC) to 1652ºF (900ºC), please use the heater output at 30 to 50%. In other words, shortlist a heater that is 2 to 3 times bigger than the heater obtained by calculation. Air flow rate L/min is obtained by F ? 0.5 x (heater rated power × heater output%) ÷ hot air temperature ºC. |

| Conventional technology | Needle valves or mass flow controllers were used for airflow control of conventional hot air heaters. However, these controls were completely analog and difficult to stabilize, and it was necessary to combine with a motor or flow meter sensor for automatic control. Though these solved the above mentioned problems, they were expensive and hence difficult to use. |

| New possibility Pulse blower | A smooth air circuit has been created inside the controller to elimination air pulsation, there is also a plan to positively utilize the air pulsation (hot air pulse blowing). These are drying and fields that use the impact of air pressure. For example, it has been reported that in the field of drying (blowing off water droplets), air consumption can be reduced by half with the use of pulse blowing ( Other company (1), Other company (2), Other company (3)). This information is for cold air pulse blowing, and you obtain hot air pulse blowing by using FCM, we think that there may be some innovative fields where this heater can be used. For example, this heater can be used to deform plastic by softening using the impact of strong air pressure. Or melting and blowing of solder. It is somewhat noisy just like a machine gun with a considerable impact of air. The pulse cycle can be selected from 0.1 sec, 0.25 sec, and 0.5 second (soft setting of the temperature setting unit for hot air) according to the use |
