Contact the manufacturer

Enquiries about the SKWEIT® ZXSJ-UVC series reach the manufacturer — Suzhou Purple Core Instant Purification Technology Co.,Ltd., the company that makes the units, holds the certificates and owns the brand. Technical questions, sample requests, documentation requests and OEM enquiries are all handled from here. The most useful thing to send is the line detail: what it serves, the peak draw, what is upstream and where in the world it is going. That is usually enough to answer the specification question in one exchange.

Need specifications before you write?

Most questions are answered by the series data sheet and the feed water conditions.

Evaluating for a regulated market?

Start with what is and is not held — compliance.

Before you write

Four questions that are already answered on the site

A large share of first enquiries are about things that are published — the flow rates, the feed-water limits, what certifications are held, and where the unit belongs. Sending the line detail instead of the question about the catalogue gets a useful answer faster, because the specification question is the one that actually needs a reply.

Where each kind of enquiry is answered
If you need…Where it is
Rated flows, fittings, materials, adapter, operation Series data sheet — both models parameter by parameter.
The water conditions the unit depends on Feed water limits and warranty conditions — the table, the mechanism behind each limit, and the warranty boundary.
Where the unit is fitted and what the install involves Installation guide — the three checks made before the line is cut, the position, the procedure and the failure modes.
What certifications are held, and what is not Compliance and point-of-use treatment — including the items that are not held and are not claimed.
What is replaced and when Replacement and service schedule — the lamp, the quartz sleeve, and how the interval is set.

What to include

The form below asks for the role, the model and the line. Where the enquiry is about a specific installation, the details that make it answerable in one exchange are the draw, the upstream filtration, whether there is a storage tank and where, and the destination market.

Enquiry routing

Enquiries are handled by enquiry type rather than in a single queue, so that a technical question is not waiting behind a pricing request.

  • Specification and samples — model selection, drawings, sample units for evaluation
  • OEM / ODM — supply into a system you build, including unit-level supply
  • Distribution — territory, documentation and market requirements
  • Documentation — certificate copies, the parameter table, the instruction manual
  • Service and spares — lamp and quartz sleeve supply against a nameplate model number

The legal entity

Who correspondence is with

The company below is the manufacturer, the certificate holder and the owner of the SKWEIT® brand. It is also the entity that issues quotations, certificates of origin and shipping documents. Where a buyer is dealing with a distributor, the manufacturer remains the party that holds the certifications — which is why the names below are worth checking against the documents that arrive with an order.

Roles in one line, and who holds what
Manufacturer roles and holdings A single card for the manufacturer showing that the same company is the manufacturer of the product, the holder of the CE certificate, the holder of the EPA establishment registration and the owner of the SKWEIT® brand. A second row marks that sales may be handled by an authorised distributor and that an authorised distributor is not the certificate holder. Suzhou Purple Core Instant Purification Technology Co.,Ltd. Kunshan, Jiangsu, China Manufacturer of the ZXSJ-UVC series CE certificate holder DPCW/01068/06/KA/26 EPA establishment 105777-CHN-1 (facility) Brand owner SKWEIT® (US reg. 8,213,072) Sales may also be handled by an authorised distributor. An authorised distributor is not the manufacturer and is not the certificate holder. Certificates issued to the manufacturer cover the models listed on them; where a distributor presents a certificate, the holder named on it is the company to check.
The certification documents carry a trade name that differs from the marketing brand. The holder is this manufacturer and the model numbers are identical, which is what makes the coverage apply — see the series data sheet for the full position.

About the contact details on this site

Sales enquiries are addressed to sales@skweit.cn, the manufacturer's mailbox, published in the footer of every page, or to the company sales line on +86 180 2176 0467, which also answers on WhatsApp. Both are company contacts rather than personal inboxes: no individual staff address and no named personal contact is published here. The form above is not yet connected to a receiving service — it is marked as such where it appears — so until that changes, email and the sales line are the channels that reach us. Where an enquiry needs to be in writing, correspondence may also be sent to the registered address above.

What to expect

How enquiries are handled

Response

Within one business day for most enquiries. Where a question needs the manufacturer's technical documentation team — a water report, a documentation request or an OEM specification — it is routed there before a reply is sent, which may take longer.

Language

Correspondence in English, and in Chinese where that is the buyer's preference. This site is published in English only; where a translated datasheet is needed for a market, that is requested rather than assumed.

What you will not get

A performance figure, a dose value or a lifetime claim that the manufacturer does not hold evidence for. If an enquiry needs one, the reply will say so and discuss the qualification programme rather than supply a number — see the datasheets.

The fastest route to a specification answer

Send the line: what it serves, the peak draw that can occur simultaneously, the tubing size already installed, whether there is a storage tank and where, what is filtering upstream, and the destination market. That is the set that decides the model, and it is the set a reply has to have.

Common questions

Contact and enquiries

How do I request a quotation?

Send the line detail and the destination market through the form on this page, noting the model or that you are unsure. A quotation includes the model that fits, the documentation that can travel with the goods, net weight and carton data, and lead time — the last three are issued per order rather than published.

Can I get certificate copies before ordering?

Yes. Original copies of the CE conformity certificate (DPCW/01068/06/KA/26) and the EPA establishment registration details (105777-CHN-1) are available to buyers on request, along with the instruction manual and the product parameter table. They are not published for download on this site.

Who do I contact about spares?

Send the model number carried on the nameplate — ZXSJ-UVC-1GPM or ZXSJ-UVC-3GPM — and the installation date. See replacement and service schedule for what is serviced.

Is there a distributor in my market?

Distribution is organised by market, and the position for a specific territory is answered on enquiry. Where there is an authorised distributor, the certificates remain with the manufacturer — the distributor is not the certificate holder, and the holder named on any certificate presented is the company to verify.

Can I visit the factory or see the production process?

Photographs of the production process are published on the about page. Arrangements for a visit or an audit are discussed on enquiry, against a specific project.
