WFR does not have any cooling capability which comes to have a big element depending on a die temperature. Therefore, might have to rely on the die cooling to make equal balance of die temperature.
New development, WFR-N series is especially designed for wide temperature range while corresponding high die temperature as before and also improving the rapid evaporation under low die temperature area.
| Model No. | Applicable die temperature | Features |
|---|---|---|
| WFR-7RN | 150-430°C (302-806°F) | Wide temperature type from 150°C (302°F) to over 400°C (752°F), suitable for the contradicting condition to prevent soldering and galling. For electrostatic spray application. |
| WFR-73RN | 130-410°C (266-770°F) | Low concentration type of WFR-7RN, to exclude the adverse effects due to excessive adhesion for easy handling. |
