Application Examples
|Application Examples
The following are some of the application examples. Since the amount of heat generated changes
with conditions and usage rates, the effectiveness is not guaranteed.
[Equipment] AC Spot Welding Machine
| Specifications | Rated capacity: 50 kVA |
|---|---|
| Chiller type | HRS024-A-20 + HRS-BP001 (Bypass piping) |
| Application |
[Parts welding for large air conditioners]
Since the water temperature increases in the current radiator type, ? the welding machine stops, and it takes time until it cools down. |
| Effect | Maintains the set temperature even after continuous operation. The sufficiently cooled torch solved the momentary stops, which improved the operability. |
[Equipment] Projection Welding Machine
| Specifications | Rated capacity: 110 kVA |
|---|---|
| Chiller type | HRS050-A-20 + HRS-BP004 (Bypass piping) |
| Application | Ground water was used conventionally, which generated condensation. Problems with flow path clogging also occurred due to the foreign objects in the poor quality water. |
| Effect | Stable water temperature prevented condensation. Stable water quality prevented further problems. |
[Equipment] AC Resistance Welding Machine (Multiple Units)
| Specifications | 30 kVA, 35 kVA, 40 kVA, 50 kVA Total of four units |
|---|---|
| Chiller type | HRS050-A-20 + HRS-BP004 (Bypass piping) |
| Application |
[Precision frame welding for medical applications]
Reduction of water costs was demanded, because tap water was used conventionally. There was a requirement to cool four resistance welding machines with one chiller (individual operation). A proposal to reduce tap water usage was presented. |
| Effect | Tap water cost: 0 JPY; Reduced about 300,000 JPY per year. Introduction costs were recovered in about two years. |
[Equipment] AC Spot Welding Machine
| Specifications | Rated capacity: 35 kVA |
|---|---|
| Chiller type | HRSE024-A-20-T + HRS-BP001 (Bypass piping) |
| Application |
[Auto parts welding]
Water piping installation was required to change from air cooling to water cooling. |
| Effect | The water resource was secured without installing new water piping. The increase in the torch temperature could also be suppressed. |
* The amount of heat generated changes with the usage rate and current value.
