Quick answer: Polygee works as a factory-direct ecology unit supplier in UAE projects, shipping kitchen ecology units (ECU) from its own factory in Zhangjiagang, China. The minimum order is one unit and the standard lead time is 7 to 15 days. Buying from the factory changes who does what: we build the treatment stages and prepare the documents, while installation, ductwork and the local submission stay with your contractor. This page sets out that split, our commercial terms in full and the documents we prepare for a consultant or authority. It ends with the eight inputs to send, so the quotation you get back can be lined up against any other.
This page helps you decide whether a factory-direct ecology unit suits your UAE project, and what to put in the first enquiry. It does not size a unit, quote a price, or file anything with a UAE authority. For sizes and stage tables, see the kitchen ecology unit page; for what sets the number, see ecology unit price.

What a factory-direct order covers, and what stays with your contractor
A factory-direct order covers the equipment and the paperwork. Everything that happens on site in the UAE stays with your local contractor. Settle who owns each line below before comparing offers, because a line left out of one quotation does not disappear; it moves to another invoice.
| Item | Factory-direct from Polygee | Your UAE contractor | What it means for your quote |
|---|---|---|---|
| Electrostatic, UV-C and activated carbon stages, with their control gear | Supplied | — | The part every offer should price the same way, so state the stages and the airflow |
| Extract fan | Available with the ecology unit, selected on the total static pressure of the configuration | Usually in the ventilation package | Say which you want, or the offer that includes a fan will read as the dearer one |
| Ductwork, transition pieces, attenuators and any fire protection on the duct | Not supplied | Yes | Adapter work left unstated turns into a variation after the order |
| Supports, hangers and structural work | Not supplied | Yes | Module weights for the hanger schedule are set out in ecology unit installation |
| Installation labor and commissioning attendance | Not included; paid on-site service is available | Yes | Price installation locally against our general arrangement drawings |
| Submission documents | Prepared against the reviewer’s list | The list itself, from the consultant or authority | A late request delays approval, not delivery |
| Making the submission | We supply the pack | Whoever holds the project submission | Tell us who that is, so the pack follows their list |
| Spare parts and consumables | Common spares held in stock; parts supplied for one year after a model is discontinued | Decide the holding you want | Quote them with the unit, so the first consumable order is budgeted |
This table answers who supplies what. It does not answer what any of it costs; that follows the stage list and the airflow.
Commercial terms, stated up front
These are the terms that apply to a UAE order. They are written out here so you can hold any offer against them, ours included.
| Term | What applies | What it means for your project |
|---|---|---|
| Minimum order | One unit | A single trial unit is a normal first order |
| Lead time | 7–15 days as standard | Freight time is added according to the route and the Incoterm |
| Payment | A 30% deposit releases production, with the balance settled before shipment; a 50% deposit is also available; T/T and L/C are both accepted | Schedule the balance ahead of the shipment date |
| Incoterms | EXW, FOB or CIF, arranged to suit the buyer | Tell us the delivery point and we quote on that basis |
| Warranty | One year on the complete unit, covering the collection cells and the SPP high-voltage power supply; UV lamps and activated carbon media are consumables and are not covered | Budget consumables separately; ecology unit filters sets out which stage is washed and which is consumed |
| Labor and site attendance | Not included; paid on-site service is available | Price installation and commissioning locally |
| Spare parts | Common spares held in stock; parts supplied for one year after a model is discontinued | Agree the spares holding with the order |
| Remote support | Video calls backed by illustrated manuals, Monday to Friday, 8:00–17:00 (GMT+8), which is 4:00–13:00 in the UAE | Plan commissioning questions for the UAE morning |
| Your brand | Your logo on the unit and a different enclosure color; quantity and lead time for OEM builds agreed case by case | State it in the first enquiry, not after the order |
| Confidential drawings | An NDA can be signed by the company | Send it with the drawings |
| Factory inspection | Each unit is inspected before shipment | Ask what the inspection covers before you place the order |
This table answers what the terms are. It does not answer the price, which is set by the stage list and the airflow as explained in ecology unit price.
Freight is the one figure this page cannot give you. Transit time to Jebel Ali or any other UAE port depends on the route and the Incoterm. Ask for it with the proforma invoice, add it to the 7–15 day lead time, and check the total against your on-site date.
Documents for the consultant or the authority
We prepare the submission pack against the list your reviewer issues: certificates, third-party test reports, general arrangement drawings and specification sheets, put together for the market you are submitting in. We have supplied projects in Dubai and across the Gulf, among them Dubai Mall in 2017 with 40 ODM units, so we know the form a submission usually takes there.
| Document | What it supports | What it does not prove on its own | What to check |
|---|---|---|---|
| CE certificate FQC2602501 (Machinery, EMC and Low Voltage directives, valid to 9 January 2031) | Conformity of the models it names: LK30–LK480, LK30E1–LK150E1 and the UV series | Coverage of any model not named on it | Match the model numbers in the offer against the certificate |
| RoHS 2.0 certificate BKC25114877LC | Restricted-substance compliance for the lines it names, the LK-E series included | Coverage beyond the lines it names | The same model-number check |
| ISO 9001, ISO 14001 and ISO 45001 certificates (ABZB25Q30072R3M, ABZB25E30043R3M, ABZB25S30027R2M) | The management systems the factory works under, the carbon stage included | The performance of any particular unit | Ask for copies with the pack |
| Third-party test reports | The result for the model and the condition tested | The result for a different model or a different condition | Ask which report covers the model being offered |
| General arrangement drawings and specification sheets | Dimensions, flange sizes, weights and electrical supply of the offered configuration | That the run fits your plant room; that check belongs to your contractor | Send them to whoever coordinates the plant room or ceiling void |
This table answers what each document can carry in a submission. It does not answer what your reviewer will accept; only their list does that. Send it to us early in the enquiry and we will work out with you how to cover each item.
The certificates behind these numbers are listed by product line on our ESP certifications page. The company facts a vendor registration usually asks for are on our electrostatic precipitator supplier profile.
Sizes at a glance
One treatment run covers 3,000 to 15,000 m³/h in eight sizes: 3,000, 4,000, 5,000, 6,000, 8,000, 10,000, 12,000 and 15,000 m³/h, or about 1,766 to 8,830 CFM. Above 15,000 m³/h the extract is split into parallel runs, confirmed on the project drawing.
The extract rate fixes the size of the UV and carbon modules. The cooking load then sets the electrostatic tier. The LK-E stage comes in three grades, at or above 90, 95 and 98 percent design efficiency: charcoal, grill and heavy wok lines sit at the top of that range, and cafés at the bottom. The carbon media is coal-based columnar activated carbon with an iodine value of at least 800 mg/g.
Two site facts decide whether a size fits. The access side of the UV and carbon stages needs 1,000 mm clear for maintenance. The brochure input supply is 220 V, 50 Hz, with 380 V and 60 Hz configured to order, so state your site supply in the enquiry. The full stage tables, flange sizes and carbon frame counts are on the kitchen ecology unit page.
Gulf projects, and what to send for a quotation
Two Gulf projects on record, with year, equipment and unit count. Ask about either when you send an enquiry. For Saudi Arabia and Qatar projects, the same terms are set out by country on our ecology unit supplier page for Saudi Arabia and our ecology unit supplier page for Qatar.
| Project | Year | Equipment | Units |
|---|---|---|---|
| Dubai Mall, UAE | 2017 | ODM units | 40 |
| Waldorf Astoria Lusail, Qatar | 2016 | LK-E series | 30 |
An enquiry that says “ecology unit, send price” gets back a number that cannot be compared with anything. The sheet below is what turns it into a quotation you can line up against other offers, including a local stockist’s. The market-neutral version of that sheet, with where each input is found and what you receive against it, is our 10-input ESP enquiry sheet.
UAE ecology unit enquiry sheet
| # | Send us | Why it matters |
|---|---|---|
| 1 | Extract rate in m³/h or CFM, and who set it | Fixes the module size in every stage |
| 2 | Cooking style and load | Sets the electrostatic tier |
| 3 | Plant room or ceiling void dimensions, with the access side marked | Decides whether the run goes in line or stacked |
| 4 | Site power supply: voltage, phase and frequency | The brochure input is 220 V, 50 Hz; other supplies are configured to order |
| 5 | Whether the extract fan is in our scope | Keeps offers comparable |
| 6 | Delivery point and preferred Incoterm | Fixes the freight basis of the proforma invoice |
| 7 | Who reviews the submission, and the document list they issue | Lets us assemble the pack to that list |
| 8 | Required on-site date | Shows whether the lead time plus freight fits your programme |
What you get back:
- A stage-by-stage configuration naming the electrostatic tier and the UV and carbon modules
- The pressure drop of each stage at your airflow, with its basis stated as cell body or complete module
- A proforma invoice on your Incoterm
- The submission pack list, matched to your reviewer
- The warranty and consumable boundary, in writing
There is no list price, because the number follows the stage list and the airflow. Ecology unit price explains what moves it.
Scope and limits
Three layers clear separately. Layer one, the offer: the configuration, the terms and the documents. Layer two, the site: installation, ductwork, supports and access decide whether that configuration goes in as quoted. Layer three, operation: delivered airflow, capture at the hood, cleaning and consumables decide the result at the discharge. Passing one layer does not clear the next.
- No prices appear on this page. Send the enquiry sheet and the price comes back against a stated configuration.
- No transit time is stated. Ask for it with the proforma invoice and add it to the 7–15 day lead time.
- Certificates cover the models they name. Check the model numbers on each certificate against the offer, ours included.
- Nothing here is an approval. The reviewing consultant or authority decides on the documents submitted, so send us their list before the pack is assembled.
- No consumable interval is given. Carbon and lamp replacement are set in writing for your site with the configuration proposal.
Key takeaways
- Scope: a factory-direct order covers the equipment and the documents; installation and the submission itself stay local, not with the factory.
- Terms: compare offers against written terms for payment, warranty and spares, not against a headline figure.
- Documents: a certificate covers the model numbers it names, so match numbers rather than logos.
- Enquiry: eight inputs make quotations comparable; “send price” does not.
Frequently Asked Questions
- Can you supply the extract fan with the ecology unit?
- Yes. The fan can be supplied with the unit when you want it quoted that way. It is selected on the total static pressure of the configuration, not on the airflow alone. On most projects the fan sits in the ventilation contractor’s package instead, so say in the enquiry which way you want it. Two offers are only comparable when both include the fan or both leave it out.
- Can the ecology unit carry our company’s brand?
- Yes. Your logo on the unit and a different enclosure color are both available, and quantity and lead time for OEM builds are agreed case by case. If the project drawings are confidential, an NDA can be signed by the company before they are shared. State the branding requirement in the first enquiry, because it affects the production schedule.
- Which documents can you provide for a UAE submission?
- The pack is assembled against the list your consultant or authority issues. It can include CE certificate FQC2602501, which names LK30–LK480, LK30E1–LK150E1 and the UV series, and RoHS 2.0 certificate BKC25114877LC, which includes the LK-E series. It can also include ISO 9001, ISO 14001 and ISO 45001 certificates, third-party test reports for the models they were issued on, and general arrangement drawings and specification sheets for the offered configuration. Check the model numbers on each certificate against the offer before relying on it.
- How do I get a price for an ecology unit in the UAE?
- Send the extract rate, the cooking style, the plant room dimensions and the site power supply. Add whether the fan is in scope, the delivery point and Incoterm, the reviewer’s document list and the required on-site date. There is no list price, because the stage list and the airflow decide most of the number. You get back a stage-by-stage configuration, the pressure drop of each stage with its basis stated, and a proforma invoice on EXW, FOB or CIF terms.
