DRYSA18 Dry Sterilizer 18 L · Hot Air · LED Controller · up to 300 °C
The DRYSA18 dry sterilizer is a small bench-top hot-air unit for salons, practices and small laboratories. It sterilises metal instruments and glassware with dry heat and also works as a drying oven, from 10 °C above room temperature up to 300 °C. There is no fan: the warm air rises by itself. Two versions share the same functions: DRYSA18 (PRO2994) with a galvanically protected steel chamber and DRYSA18S (PRO8274) with a polished stainless-steel chamber.

DRYSA18 dry sterilizer models and order codes
| Model | Order code | Chamber material | Inner chamber W × D × H | Exterior W × D × H | Heating power |
|---|---|---|---|---|---|
| DRYSA18 | PRO2994 | galvanically protected steel | 260 × 260 × 260 mm | 380 × 455 × 568 mm | 0.6 kW |
| DRYSA18S | PRO8274 | polished stainless steel | 260 × 260 × 260 mm | 380 × 455 × 568 mm | 0.6 kW |
Both versions of the DRYSA18 dry sterilizer have the same 18 L chamber size, controller, timer and shelves; they differ only in the chamber material. Not sure which one you need? Send us what you sterilise or dry and how much per run, and we will propose the version.
Dry sterilizer with LED controller and timer
In the DRYSA18 dry sterilizer the warm air rises from the heater through the chamber by natural convection. There is no fan, so the unit is quiet and has few parts that can wear. The LED display shows the measured temperature on the upper row and the setpoint on the lower row. The timer runs from 0 to 9999 minutes and switches the heating off at the end of the set time.
Key features
- Temperature RT+10 °C to 300 °C, resolution 0.1 °C
- Natural convection, no fan
- PID controller with LED display and timer 0–9999 min
- Over-temperature alarm with sound and light
- Chamber 260 × 260 × 260 mm, 2 shelves supplied, 6 shelf positions
Suitable for
- Dry-heat sterilisation of metal instruments in cosmetic and hairdressing salons and in podiatry
- A dry sterilizer for small dental and veterinary practices
- Hot-air sterilisation and drying of laboratory glassware
- Warming and heat treatment of small items up to 300 °C
Galvanically protected steel or stainless steel?
The DRYSA18 has a chamber of galvanically protected steel. It is the economical choice when the load is dry: clean, dried instruments and glassware. The DRYSA18S has a chamber of polished stainless steel, which is easier to wipe clean and resists moisture and frequent cleaning better.
If you need a larger chamber or a fan for faster, more even heating of a full load, see the laboratory drying ovens overview .
How to use a dry sterilizer
Dry heat sterilises only clean, dry items, so wash and dry the instruments first. Place them in one layer on the shelves and leave space between the items and the chamber walls, so the warm air reaches every surface. Set the temperature and the time according to the procedure that applies to your work; the controller keeps the temperature and the timer ends the cycle. Let the load cool before you take it out. A dry sterilizer is suitable for metal and glass, not for liquids, textiles, plastics or other items that do not withstand dry heat.

Operating functions
PID controller with LED display
The PID controller holds the set temperature and corrects itself by self-tuning. Settings are kept after a power cut, and the parameters can be locked.
Timer and protection
Set the timer from 0 to 9999 minutes; the dry sterilizer stops heating at the end of the set time. An alarm with sound and light warns when the temperature goes above the limit. Do not load flammable, explosive or solvent-containing materials.
Versions
The dry sterilizer is available in two versions with the same 18 L chamber: DRYSA18 with a galvanically protected steel chamber and DRYSA18S with a polished stainless-steel chamber.
Construction, installation and care
The housing is powder-coated cold-rolled steel with rock-wool insulation, and the door has a window and a handle that stays cool. Place the dry sterilizer on a level, heat-resistant bench, with free space around it and above the exhaust port, and connect it to an earthed socket. Clean it cold, with neutral detergent and a dry cloth; do not use acids or alkalis.
Standard delivery
