Frequently Asked Questions

Our goal here is to really understand what you need. We don't just sell machines; we provide solutions with the help of our expert engineering team.

1. How can I get detailed information about your Ozone Generators, Oxygen Concentrators, or Micro-Nano Bubble systems?

Getting in touch is easy, and we're ready to help:

Send an Email: Outline your needs and email us at [Insert Your Email Address Here]. We promise to get back to you within 24 hours.

Live Chat: Prefer to chat now? Use the chat box on our website to talk to a real person immediately.

Give us a Call: If your project is complex, a quick phone call is a great way to start.

2. I'm not sure which technology I need (Ozone, Oxygen, or Micro-Nano). Can you help me figure it out?

Absolutely! This is what we do best.
Just tell us about your application. Are you treating wastewater? Disinfecting a room? Working in aquaculture or food processing? Let us know the scale or space you're dealing with.

Dedicated Support: A specialist familiar with your industry will be assigned to you.

Real Engineering Input: Our engineers will jump on a call with you to understand your process and challenges. We provide honest, expert advice, not just a sales pitch.

3. Will you provide a detailed proposal and quote? What's included?

Yes, we offer a detailed technical proposal and a clear quote completely free of charge.
Once we understand your needs, our team will put together a plan that includes:

The Right Equipment: We'll specify the exact model. For example, should it be an air-fed or oxygen-fed ozone generator? Do you need a matching oxygen concentrator? Which micro-nano bubble diffuser or pump is best?

Complete System Design: Details on the air source, cooling method, and how to inject the gas into your system.

Technical Drawings: If needed, we'll provide P&ID diagrams or installation layout suggestions.

Accurate Pricing: A clear, itemized list of all equipment and associated costs.

4. Are your engineers truly technical experts, or are they just salespeople?

We believe in the power of both.
Your initial contact will be with a knowledgeable sales specialist. However, the moment your questions get technical or your project becomes complex, we bring in our senior after-sales and R&D engineers. They are the real deal—the people who design and understand the technology inside and out. This ensures the solution we propose is scientifically sound and perfectly practical.

This section covers the nitty-gritty: contracts, secure payment, and what to expect while waiting for your equipment.

5. After I place an order, how long until it ships? (Lead Time)

Shipping times depend on the product:

Standard Models (e.g., common ozone generators/oxygen concentrators): Usually ships within 7-15 working days after receiving the deposit.

Custom Systems (e.g., large-scale micro-nano bubble setups): These are built to your exact specifications, so they take a bit longer. Expect a lead time of about 20-30 working days.

Your sales contract will always have the most accurate delivery date.

6. What are your payment terms?

To keep things safe and fair for everyone, we follow standard business practices:

Typical Terms: A 30%-50% deposit is required to begin production, with the balance paid before we ship the goods.

Letters of Credit (L/C): For certain countries and regions, we also accept L/C at sight.

Just talk to our sales team—we can often find terms that work for both of us.

7. What is your warranty policy? What does it cover?

We stand behind the quality of our products.

Warranty Period: We generally offer a 12-month warranty from the date of shipment (details are in your contract).

What's Covered: Any defects or failures resulting from faulty design, materials, or workmanship during normal use.

What's Not Covered: Normal wear-and-tear items like filters or fuses aren't covered, but we can supply replacements at a fair price.

8. What if my order arrives damaged or the wrong item?

Please inspect your shipment immediately upon arrival.

Shipping Damage: If there's visible damage from transit, note it clearly on the delivery receipt and take photos. Contact us within 24 hours.

Wrong Items: If the product or quantity doesn't match your order, let us know right away. We will verify the issue and arrange for a replacement or correction as quickly as possible.

This is where we build a lasting partnership. We want to make sure you're successful with your equipment.

9. Who installs the equipment? Do you offer help?

Yes, we provide comprehensive installation support.

For Local Clients: We offer on-site installation and commissioning (if agreed in the contract). Our engineer will come to your site to oversee positioning, piping, power-up, and testing, and will train your operators.

For International/Remote Clients: We offer one-on-one remote video guidance. Using WhatsApp, Skype, or WeChat, our engineers will guide your team through the setup, step-by-step. You'll also receive detailed manuals and instructional videos.

10. What if I have a problem while the machine is running?

We're here for you through multiple channels:

24/7 Online Support: You can always leave a message via email or social media. We respond promptly during business hours.

Remote Diagnosis: For control system issues, our engineers can often log in remotely to diagnose problems and optimize settings.

Spare Parts Support: We have spare parts warehouses or partners in key markets to get you critical parts fast.

11. Do you provide training on how to use the equipment?

Absolutely. Whether we're there in person or guiding you remotely, we will train your operators. Training covers:

Proper start-up and shut-down procedures.

How to adjust operating parameters.

Daily and routine maintenance (like checking ozone generator cooling water, maintaining oxygen concentrator sieves, or cleaning micro-nano bubble generators).

How to troubleshoot simple, common issues yourself.

12. My warranty has expired. Can I still get it repaired?

Of course! We offer lifelong paid repair services.
Even after your warranty ends, you're still part of the XIN Ozone family. We're always here for technical support. If you need repairs or spare parts, we only charge cost price for parts and a basic service fee. No hidden costs, no surprises. You're always our customer.
