About Purificadora

Purificadora has a trained and qualified team with over 30 years of experience.

It was the first company in Portugal to recycle industrial oils.

Purificadora works for public or private companies, from micro-enterprises to large economic groups, both national and multinational:

- Rolls Royce;
- Amorim Group;
- Mello Group;
- Portucel Soporcel Group;
- Sonae Group;
- Others.

Purificadora is certified by the NP EN ISO 9001 and NP EN ISO 14001 standards.

All other permits and licences are available for consultation or download in our downloads section.

We recycle (or depending on the adopted vocabulary: purify, recover, treat, etc.) new and used industrial oils to reuse them in the same process or original application.

We carry out analyses and tests on oils in our in-house laboratory, or when necessary, in external laboratories.

We sell the only EC approved leak-proof silica gel filters.

Purificadora has a vast experience with transformers. We recycled the oil from the largest transformers in Portugal, each with 96,000 kg. We highlight some of the brands that are part of our portfolio:

- ABB Asea Brown Boveri;
- AEG;
- Alkargo;
- Efa;
- Efacec;
- Enae;
- France Transfo;
- GE General Electric;
- Motra;
- Pauwels;
- Schneider Electric;
- Siemens;
- Others.

Purificadora has a vast experience with turbines. We highlight some of the brands that are part of our portfolio:

- ABB Asea Brown Boveri;
- Ansaldo;
- Alstom
- GE General Electric;
- Rolls Royce;
- Siemens;
- Others.

About the recycling machines

Purificadora has machines to recycle insulating/dielectric oils and machines to recycle the remaining oils. This ensures that no mixing or contamination occurs between oils and between machines.

Among each type of machine, we have machines with different recycling flows. This enables us to operate from the smallest to the largest equipment (such as transformers with 96,000 kg of oil).

All recycling machines are developed and built by Purificadora, which uses state-of-the-art technologies, some unique worldwide.

All machines were and are developed according to specific type of oils and type of equipment, thus allowing us to achieve unrivalled levels of performance. The algorithms and methods used are continuously improved to reflect the latest technological advances and acquired experience.

About the process

The recycling can be done while the equipment is in operation, which is the preferred working method for Purificadora.

We are available 24/7, responding promptly in emergency or forced shutdown situations.

The physical and chemical properties are retained and improved, which is why we are recommended by oil companies and equipment manufacturers.

The manufacturers of some equipment require new oil to be purified by Purificadora before it is used in their equipment. This is because the levels of humidity and particles in new oils are not ensured, which can cause breakdowns or equipment malfunction.


01. Fill in the adhesive label and the request;
02. Stick the label on the bottle before you collect the oil;
03. Clean the oil collection point;
04. Fill the bottle leaving the upper part of the lid free;
05. Put the lid and twist it until it is tightly sealed and no oil is spilled;
06. Place the bottle back into the plastic bag and close it properly;
07. Place the pair of used gloves in the box;
08. Close the box and attach the respective shipping labels.

Oils should be recycled because:

- The cost of recycling oils is 350% or more cheaper than the cost of new oil;

- The oil can be recycled several times without losing its physical and chemical properties;

- Its recycling reduces maintenance costs and national crude oil consumption;

- Annual waste and all associated costs are reduced.

For electrical transformers any amount can be recycled.

For all other types of oil we generally recommend a minimum of 1,000L, below this amount the cost of displacement may be higher than the cost of treatment. However, if possible, we can pool work in the same geographical area to solve this issue.

Purificadora's activity is certified in accordance with the NP EN ISO 9001 and NP EN ISO 14001 standards.

The oil is analysed and tested (either in our laboratory or in external laboratories) in order to prove the quality of the service provided.

We guarantee that our recycling process (which is physical and not chemical) does not degrade or negatively alter the physical and chemical properties of oils. Any statement to the contrary is false and due to vested commercial interests. In fact, there are studies carried out by international universities and other renowned institutions that prove and recommend this type of oil recycling.

About silica gel filters

Compare the reasonable cost of a Des-Case filter with the cost of equipment repair, downtime, oil changes, contaminated or damaged products, etc.

Here are some examples:

1. Repairing a gearbox can cost hundreds and even thousands of euros in parts and labour, not to mention the wasted time;
2. The failure of one piece of equipment can stop an entire production line;
3. Oils used in the food industry that have been contaminated must be disposed of;
4. Moisture in electrical control cabinets and transformers can lead to explosions.

Des-Case filters are easy to install, and their periodic monitoring requires no technical expertise.

Des-Case filters use blue silica gel. Blue silica gel is not banned, contrary to what has been conveyed to the general market, instead it has been reclassified in terms of its hazardousness.

Other types of silica gel on the market are either banned and/or are much more dangerous/carcinogenic than blue silica gel.

Des-Case filters comply with the REACH regulation and all units are identified as compliant with such regulation:

All traditional refill filters are subject to registration under the REACH regulation.

The import, distribution and use of chemical substances that do not comply with the REACH regulation or are not pre-registered by the European Competent Authorities by 1 December 2008, will be prohibited. This means that after 1 December 2008, downstream users will have to have official proof that the substances they use comply with the REACH regulation or are pre-registered for the particular use for which they are intended.

Under the REACH regulation, substances that are intended to be released as part of the product's functionality (e.g.: the ink from a print cartridge) must comply with the REACH regulation or be pre-registered before 1 December 2008. Downstream users that want to use desiccator filters that are designed to be refilled or opened after 1 December 2008, must have proof that all the chemical substances present in such filters - including additional oil residues and additives used for colour change - are pre-registered for all kinds of individual applications.
