Product & supply options
A requirement brief, supplier questions and a review of proposed configurations and quotation differences.
Tianchang & nearby sourcing / OEM components
Ozone Module & Power Assembly Sourcing
Ozone module and power assembly sourcing for equipment manufacturers and importers.
Bring the application, the interfaces and the help you need. We turn them into a purchasing brief, supplier questions and approval points before a sample or order is agreed.
A defined purchasing task
More than a catalogue match.
A similar-looking module does not establish electrical compatibility. State whether you need a module, a power assembly, a matched package or a change to an existing arrangement.
We coordinate the purchasing questions. The supplier must confirm the proposed configuration, interfaces and quotation assumptions; you approve the requirements and the next step.
Before comparing offers
Define what is included.
Match the purchasing scope
- Module only: identify the existing power and control arrangement.
- Power assembly: identify the intended load and equipment interfaces.
- Matched package: define what must be supplied and tested together.
Compare on the same basis
Record the model revision, included parts, sample or development costs, checks, packaging and delivery assumptions. Highlight differences and exclusions—not just the quoted total. A comparison is not a lowest-price guarantee.
Scope to agree
Choose the work you need.
Customization & samples
Interface questions, revision notes, a sample plan and a record of feedback and approvals. Feasibility and costs need supplier confirmation.
Order follow-up
Agreed milestones, change records and an open-issue list. Deviations are referred to the authorized party before corrective work or shipment decisions.

Make each approval traceable.
Set the conditions
Write down essential interfaces, test conditions and unresolved questions.
Confirm the proposal
Identify the supplier, revision, included parts, costs and sample arrangement.
Check against the brief
Record fit, connections and the agreed test results. Visual inspection is not laboratory testing.
Resolve differences
Log deviations and changes. Obtain your written approval of the accepted revision.
Authorize the next step
Confirm scope, checkpoints and decision owners before the order proceeds.
Your first message
Start with what you know.
- Equipment application, intended use and destination country.
- Module, power assembly, matched package or existing-supplier task.
- Known supply, load and control interfaces; mark undecided items.
- Space, mounting, cooling and operating-environment constraints.
- Estimated quantity, sample needs and preferred schedule, if known.
- Sample acceptance conditions and the person or role approving them.
Keep the first brief non-confidential.
No file uploads. Email info@25tc.com first if documents need discussion. Do not put confidential drawings or private download links into the initial form.
For an existing supplier, include its city and the specific task you authorize. We assess practical access and follow-up in Tianchang and nearby areas—not nationwide coverage.
Roles & costs
Know who is responsible.
25TC is operated by Anhui Morhon Technology Co., Ltd. The supplying entity, our coordination role and the buyer's approval responsibilities are identified for the project.
You may contract directly with the supplier and agree a separate service, or discuss a broader managed arrangement. Supplier payments, service fees, samples and third-party expenses are agreed in writing before paid work.
Confirm technical suitability before ordering.
The proposed configuration, electrical interfaces, operating conditions and sample acceptance criteria need confirmation before an order is agreed. The supplier confirms the proposed configuration; the buyer approves the agreed requirements and sample.
Before you enquire
Questions to settle early.
Who supplies the parts?
The supplying entity and 25TC's role are confirmed before a commitment. Where our own or associated manufacturing resources are involved, that relationship is identified; it is not presented as an independent third-party factory audit.
Can you quote from a photograph?
A photograph helps identify a category, not its ratings or compatibility. A useful offer needs the configuration, acceptance conditions, quantity and commercial scope. No current stock, fixed price, MOQ or lead time is offered on this page.
What if a sample or order differs from the brief?
Record the difference, the supplier's proposed response and any cost or timing effect. Revisions, corrective work and shipment decisions require the authorization agreed for the project; they are not automatic approvals.
Does a component document cover my finished equipment?
No certification claim is made here. Model identity, document scope and destination requirements need separate review. A component document does not automatically cover the finished equipment.
What if my specifications are incomplete?
Send what is known and mark what is undecided. We first assess the regional sourcing task and identify missing confirmations. An inquiry is not an order or an agreement to a service fee.
Start with the requirement
Tell us what must fit your equipment.
Application, destination and the help you need. We will review the regional scope and the next confirmations.
