Low Vacuum Oven LVO

Our Vacuum ovens LVO are suitable for drying* of sensitive products, thermal treatments of oxidizable materials, quick drying of powders and granulate... in pharmaceutical, cosmetics, plastics, electronics, chemical, agrifood… laboratories or industries.

* For any drying application, please contact us to explain exactly your need to info@plasmadiam.com. We will help you to find the products adapted to your needs.

Max temperature : 200°C**
** We can make vacuum ovens above 200°C, consult us !

Vacuum range :
from 0 to -1000 mbar (relative pressure)

6 sizes : 20, 51, 110, 220, 316 and 512 liters.

A solid construction
for lasting performance.

Exterior made of steel coated with blue and white epoxy paints The inner casing is made of corrosion resistant strong thick stainless steel.

THICK INSULATION

No contact between the inner and outer casings for no thermal bridge. Insulation is made of asbestos-free glass wool : low surface temperature, low electrical consumption, a rapid rise in temperature.

DOOR WITH VIEWING WINDOW

The door is equipped with a thick safety glass.

SEALING

A silicone gasket provides the seal of the door. It may be replaced by a viton seal (optional). Closing the door by adjustable clamps.

EASY CLEANING

The rounded corners of the inner casing make easier cleaning operations ; the racks and the seal are easy-to-remove.

An efficient heating.

Heating is ensured by heating elements located on outer faces of the inner casing for the best homogeneity.

Note : the temperature sensor is fastened on the wall inside the oven. Therefore, there is a difference between the temperature on the tray and that displayed on the temperature controller of the oven.

Easy temperature controls.

Vacuum ovens LVO feature a DN16KF passage with a silicone plug. It is possible to introduce up to 4 temperature sensors for temperature measurements inside the oven.

An easy connection of your vacuum pump.

The electrical connection of the vacuum pump is made directly to the back of the oven. Teats allow the pumping of air and vacuum breaking (LVO-020 and LVO-050). From LVO-120 model, pumping connector type is KF.

A reliable vacuum control

The digital vacuum controller displays the indoor relative pressure of 0 to -1000 mbar.

A switch on the control panel allows to achieve the maximum vacuum level of your vacuum pump, or to maintain a constant level of pressure preset on the controller.

Note : It is possible to change the vacuum level at any time of the cycle by changing the value on the vacuum controller. If the desired level is lower : air is pumped automatically. If the desired level is higher : first make the air manually enter inside the oven and then it will be pumped up the desired level.

The C3000 temperature controller : accuracy and reliability. 

The C3000 temperature controller is a highly accurate and highly reliable microprocessor. Very efficient and extremely easy to use. Measurement by PT100 sensor. PID electronic regulator. Accuracy: 0.1°C.

Functions :

• Setpoint display and that measured.
• Delayed Start : 1min to 99h59min.
• Heat ramp.
• Heating timer from 0 to 99h59min.
• Repeat loop.
• Buzzer at the end of a cycle.
• Over temperature alarm.

Protections for your oven and your products.

An adjustable and non-resettable mechanical thermostat (class 3.1 protection) protects the oven/product against overheating. It measures the temperature in the volume, and supports the regulation in case of failure of the temperature controller.

It stops heating until the temperature has dropped below the value of its setting. With visual and audible alarm.

Note : It's possible to control the oven with a computer through a RS232 cable.

Loading trays

Vacuum ovens LVO are provided with 1 aluminum tray.

Multiple load levels are available for easy loading and unloading.

Each tray can hold up to 30 kg distributed.

Guide bars have an anti-tilting system.

The racks are easily removable for easy cleaning.
