DRYSD Forced Air Drying Oven · LED Controller · 30 to 625 L · up to 300 °C
The DRYSD forced air 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 a PID controller with LED display holds the set temperature. Seven sizes share the same functions: 30 L (PRO2961), 45 L (PRO2957), 65 L (PRO2958), 85 L (PRO3044), 125 L (PRO2969), 230 L (PRO3014) and 625 L (PRO3015).

Every DRYSD forced air drying oven has the same controller, fan and stainless-steel chamber; the seven 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 air drying oven with LED controller and timer
In the DRYSD forced air 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. 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.
Key features
- Temperature RT+10 °C to 300 °C, resolution 0.1 °C
- Forced air circulation with fan; fan switch
- PID controller with LED display and timer 0–9999 min
- Over-temperature protection
- Mirror stainless-steel chamber, 2 shelves supplied
Suitable for
- Drying glassware, powders, soil, food and other samples
- A forced air 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.
For light powders that a fan could disturb, an oven with natural convection is the better choice; see the laboratory drying ovens overview .
Technical specifications

Chamber, housing and supply
| Chamber | mirror stainless steel |
| Housing | cold-rolled steel, powder-coated |
| Shelves | 2 supplied; 15 kg per shelf |
| Exhaust port | Ø 28 mm on top (DRYSD230 rear, DRYSD625 double top) |
| Protection | over-temperature protection |
| Supply | 220 V, 50/60 Hz; 110 V on request |

The setpoint must be at least 10 °C above room temperature. DRYSD230 and DRYSD625 stand on castors.
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 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 air drying oven is available in seven chamber sizes, from 30 to 625 L, with the same functions. The 625 L model works on 220 V or 380 V.
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.
Standard delivery
