Two product groups that fail for the same reason
Filtration media and incineration equipment are usually sold by different companies, so when a baghouse underperforms nobody owns the problem. We supply both — specified and sourced from manufacturing partners in Shandong, China — and we take responsibility for the pairing.
What we actually do
Ecoterva is a trading and technical sourcing company. We do not pretend to be a factory with a thousand workers — we work with a small number of manufacturing partners in Shandong, one of China's dense filtration-media and environmental-equipment clusters, and we stay responsible for the specification, the quality check and the shipment.
That model has one advantage for a buyer: the person who answers your technical question is the same person who checks the bags before they are loaded. There is no handover between a sales office and a production floor.
- Filter bags: eight needle felt media, made to drawing, sampled before bulk production
- Pulse valve diaphragms: NBR, Viton and EPDM, matched to your valve family
- Incinerators: 10–500 kg/h two-chamber units, configured to your waste and emission limits
- Export packing, documentation and shipping coordination from China
How an order runs
- You send gas data, bag dimensions or the valve model
- We reply with a material or model recommendation and its limits
- You receive a drawing or specification sheet for confirmation
- Sample or first article where the application is critical
- Production, in-line check, packing photos before shipment
- Shipping documents and a single contact until it lands
What we do not claim
Most supplier websites in this industry overstate. Here is the boundary, so you can judge us on facts instead of adjectives.
No invented certifications
We do not hold a type approval or CE-style certificate for the incinerators, and we will not send you a doctored one. What we do provide is process data — secondary chamber up to 1200 °C, gas residence over 2 seconds, destruction rate ≥99% — and a third-party emission test report on the unit as built, when testing is arranged at commissioning.
No borrowed reference lists
You will not find a wall of project logos here. If you want references for a specific application, ask, and we will tell you honestly what we can and cannot show.
No "one media fits all"
If polyester is the right answer we will quote polyester, even though PPS earns more. If your gas will destroy the media you asked for, we will say so before you order, not after.
No silent substitution
Grams per square metre, fibre type and finish are stated on the packing list. If a batch differs from the approved sample, you hear it from us first.
Where we ship
Small bag and diaphragm orders go by air courier — usually 5–8 days door to door, which matters when a baghouse is down. Full container loads of bags or an incinerator ship by sea from Qingdao or Tianjin.
- Courier: samples, spares, urgent replacement sets
- Air freight: 100–500 kg orders
- Sea freight: containers, incinerators, project shipments
- Documents: invoice, packing list, certificate of origin on request
Working language and time zone
We work in English and Chinese. We are based in Wuhan (GMT+8) and our factory partners are in Shandong, so a message sent from Africa or Europe in the morning is usually answered before your afternoon — and if a baghouse is down, tell us in the subject line and we will treat it as urgent.
Most quotations go out within one working day. If we need to ask the factory for a non-standard dimension, it can take two.
Ask us something difficult
Acid dew point, air-to-cloth ratio, why the last set of bags failed in nine months — the technical questions are the ones worth asking before an order.
