Vacuum drying oven DZF-6090

Vacuum drying oven DZF-6090

1、 Usage Overview

vacuum drying ovenSpecially designed for drying heat sensitive, easily decomposable, and oxidizable substances, it can be filled with inert gas inside, especially for some complex components that can be quickly dried.

2、 Product Features

1.The rectangular studio achieves a large effective volume, and the microcomputer temperature controller provides precise and reliable temperature control.

2.Tempered steelThe double-layer glass door allows for easy observation of objects inside the studio, and can be filled with inert gas.

3.The tightness of the box door closure can be adjusted, and the integrated synthetic silicon door sealing ring ensures high vacuum inside the box.

4.The studio is made of stainless steel plate (or cold-rolled plate), which is easy to clean and makes the products durable.

5.Storage, heating, testing, and drying can be carried out in an environment without oxygen or filled with inert gas, without causing oxidation.

3、 Technical parameters

Note: ① Performance parameter test under no-load conditions: ambient temperature 20℃, environmental humidity 50% RH

② Except for 6090 and 6210, all other models are equipped with vacuum pumps.

Precautions for use

1. The outer shell of the vacuum box must be effectively grounded to ensure safe use.

2. The vacuum box should be used in an environment with a relative humidity of ≤ 85% RH, no corrosive gases, no strong vibration sources, and no strong electromagnetic fields around it.

3. The vacuum chamber has no explosion-proof or anti-corrosion treatment, and flammable, explosive, or corrosive gas producing items must not be placed for drying.

4. The vacuum pump cannot work for a long time, so when the vacuum degree reaches the requirement for drying the item, the vacuum valve should be closed first, and then the power supply of the vacuum pump should be turned off. When the vacuum degree is lower than the requirement for drying the item, the vacuum valve and power supply of the vacuum pump should be turned on to continue vacuuming, which can extend the service life of the vacuum pump.

5. If dry items are damp, it is best to add a filter between the vacuum box and the vacuum pump to prevent damp gases from entering the vacuum pump and causing it to malfunction.

6. If dried items become lightweight and small in size (in small particles) after drying, a barrier net should be added to the vacuum port in the working room to prevent damage to the vacuum pump (or solenoid valve) caused by the inhalation of dry materials.

7. After multiple uses, the vacuum box may not be able to evacuate. In this case, the door seal should be replaced or the extension distance of the door latch on the box should be adjusted to solve the problem. When the drying temperature of the vacuum box is higher than 200 ℃, slow air leakage will occur (except for 6050, 6050B, 6051, 6053). At this time, remove the cover plate behind the box and use an Allen wrench to loosen the heater base, replace the sealing ring or tighten the heater base to solve the problem.

If the rubber plug of the vent valve has difficulty rotating, it can be lubricated with an appropriate amount of grease inside. (such as Vaseline)

9. Except for maintenance, do not open the left box cover (except for 6090 and 6210 models) to avoid damaging the electrical control system.

10. The vacuum box should be kept clean regularly. The door glass should not be wiped with reactive chemical solutions, but should be wiped with a soft cotton cloth.

11. If the vacuum box is not used for a long time, wipe off the exposed plated parts and apply neutral grease to prevent corrosion. Cover them with a plastic film dust cover and place them in a dry room to prevent electrical components from being damaged by moisture and affecting use.

When the vacuum box does not require continuous pumping, the vacuum valve should be closed first, and then the power supply of the vacuum pump should be turned off, otherwise the vacuum pump oil should be poured back into the box.
