Designed for maximum precision, capacity, and ease of use, with a 3-year warranty and guaranteed spare parts for 10 years.
Thermal Performance:
- 900°C in 60 minutes with uniform temperature distribution
- 4-sided heating with denser coils in critical areas (comparable to a hot air circulating oven)
- Monolithic muffle without joints to eliminate localized heat loss
- PtRhPt type S thermocouple for maximum precision and durability
- Display showing the actual temperature at cylinder height
Capacity:
- 9 size 3 cylinders, or 4 size 6 cylinders, or 3 size 9 cylinders
- Special ceramic fiber door usable as a support surface for cylinders during movement
Cleaning and Fume Management:
- Inclined ceramic plate with adjustable tilt angle: liquid wax flows to the back of the furnace
- Renfert catalyst for optimal wax combustion
- Fume evacuation via chimney (not from the door): significant odor reduction, always clean furnace
Intuitive Programming:

- Direct input of cycle end (date/time): no manual calculations
- Controlled gradient from 0 to 9°C/min
- Control panel with intuitive symbols, program/enter/escape/timer buttons
- Copyable programs to manage variants without re-entering parameters
Warranty and Reliability:
