DRYSE Forced Convection Drying Oven · LCD Controller · Temperature Limiter · 30 to 230 L · up to 300 °C
The DRYSE forced convection drying oven dries, heats and sterilises glassware and samples from 10 °C above room temperature up to 300 °C. A fan moves the hot air upwards through the stainless-steel chamber, and its LCD controller is combined with an independent temperature limiter that protects the samples if the controller fails. Six sizes share the same functions: 30 L (PRO3094), 45 L (PRO2959), 65 L (PRO2960), 85 L (PRO3359), 125 L (PRO3360) and 230 L (PRO3135).

Every DRYSE forced convection drying oven has the same LCD controller, temperature limiter and stainless-steel chamber; the six sizes differ in chamber size and heating power. Not sure which size you need? Send us what you dry and how much per run, and we will propose the model.
Forced convection drying oven with LCD controller and temperature limiter
In the DRYSE forced convection drying oven, the fan moves hot air from the bottom upwards past every shelf, so loads dry faster and more evenly than in an oven with natural convection. On the 30 to 125 L models the fan speed is adjustable. The LCD display shows the measured temperature on the upper row and the setpoint on the lower row. The independent limiter switches the heating off if the temperature goes above the value you set on it. The timer runs from 0 to 9999 minutes.
Key features
- Temperature RT+10 °C to 300 °C, resolution 0.1 °C
- Forced air circulation with fan; adjustable fan speed (30 to 125 L)
- PID controller with LCD display and timer 0–9999 min
- Independent temperature limiter and over-temperature protection
- Mirror stainless-steel chamber, 2 shelves supplied
Suitable for
- Drying glassware, powders, soil, food and other samples
- A forced convection drying oven for drying to constant mass, for example at 105 °C
- Hot-air sterilisation of glass and metal items
- Heat treatment, ageing and curing tests up to 300 °C
Forced air or natural convection?
With a full chamber or items on several shelves, a fan gives a more even temperature and a faster return to the setpoint after the door is opened. A forced air drying oven also dries wet loads faster, because the moist air is carried to the exhaust port.
The limiter is a second, independent safeguard next to the controller. You set a limit slightly above the working temperature; if the temperature goes above it for any reason, the limiter switches the heating off. A drying oven with temperature limiter is therefore the safer choice for valuable or heat-sensitive samples and for long runs. It needs no special installation: a level bench and an earthed socket are enough. The limiter is set separately, independently of the controller.
For light powders that a fan could disturb, an oven with natural convection is the better choice; see the laboratory drying ovens overview .

Operating functions
PID controller with LCD 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 oven stops heating at the end of the set time. Over-temperature protection is built in. Do not dry flammable, explosive or solvent-containing materials.
Sizes
The forced convection drying oven is available in six chamber sizes, from 30 to 230 L, with the same functions. Two shelves are supplied with every oven and further shelves can be ordered. On request: RS485 interface, programmable controller or touch screen.
Construction, installation and care
The chamber is mirror stainless steel and the housing is powder-coated cold-rolled steel. Place the oven level, with free space around it and around 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.
