Clinical overview
Product overview
The OpticsMED NH-300 is the 4-step temperature frame heater with explicit cold/hot air switching capability. The free switch between cold and hot air lets the dispenser cycle the frame through alternating heat-cool steps quickly — useful for thick titanium frames where the metal needs to be hot for shaping but quickly cooled to set the shape before the patient's adjustment is lost.

- 4-step adjustable temperature
- Free switch between cold and hot air
- Automatic 5-minute power-off (no-operation safety)
- Compact 200 × 150 × 170 mm footprint
- 500 W heating power
- Heats frames fast and uniformly
