Define Requirements
Technical Needs
Start by making a list of what you need. Think about the machines you use every day. Write down the voltage, current, and power your equipment needs. Check if your system needs special things, like speed control or saving energy.
Before picking an OEM VFD supplier, see if they can make enough drives for you. Make sure they can give you all the drives you need. Ask what materials they use in their VFDs. Good materials help the drives last longer and work better. Think about how the drives will help you in the long run. High-quality products have fewer problems and save you money over time.

You can find VFDs for HVAC systems, industrial pumps, conveyor belts, and machine tools. Each type of VFD works best for a certain job.

Check OEM VFD Supplier Credentials
Certifications & Standards

Production Capacity
A good supplier can give you what you need on time. You should check if the supplier can handle big or quick orders. Ask how many drives they make each month. Find out if they have enough workers and machines for your needs.
Canroon is a good example. They have new factories and skilled workers. This means you get your orders fast, even if you need a lot. Good production keeps your business running and stops delays.

Consider Environment & Delivery
Operating Conditions
You have to think about where your VFD will be used. The place it works can change how long it lasts. It also affects how well it works. Heat is a big problem for VFDs. If too much heat builds up, the VFD can stop working. Overheating can hurt the intelligent power module and other parts. Always check the temperature where you want to put the VFD.
Heat, dust, and wet air can make your VFD wear out faster.
Dust and water can get inside and cause trouble.
High heat can make the VFD get too hot and break.
You might need air conditioning to keep it cool.
Sometimes, you need a special box to keep out dust or water.
Look for VFDs with NEMA 12 or NEMA 4 ratings for more safety.
Always check the lowest and highest temperatures your VFD can handle.
Make sure your VFD can work with the height and wetness in your area.
Tip: Keeping out heat, dust, and wet air helps your VFD last longer and work better.
Timely Delivery
Getting your VFDs on time is very important. If they come late, your business can have problems. You might lose money. Your customers may stop trusting you. Some companies even have to pay extra money if they are late.
Late shipments can hurt your customer relationships for a long time. Some OEMs or tier suppliers even have to pay fines for missing SLAs.
You want a supplier who can deliver when you need it. Good suppliers use smart ways to make sure you get your order on time.
Delays can make you lose money.
Your company’s name can get worse.
You might have to pay fines if you are late.
Note: Always ask your supplier how they deliver and what they do to stop delays. Getting your VFDs on time keeps your projects moving and your customers happy.
Review Reputation
Customer Feedback
You should see what other customers say about your OEM VFD supplier. Real reviews help you know what to expect. When you read them, check for comments about delivery, quality, and support. If many people say delivery is fast and help comes quickly, the supplier cares about service. A supplier with many repeat buyers is usually trusted by customers.
Tip: Pick suppliers with at least 95% on-time delivery and a response time of four hours or less. These numbers show the supplier values your time and keeps your business running.
You can also ask the supplier for references. Talking to other buyers helps you learn about their real experiences. If you hear about the same problems again and again, you should think twice before choosing that supplier.
Industry References
Industry references and case studies show if a supplier meets high standards. You want to work with companies that have a strong record. Suppliers in business for over five years and with more workers often give steady service. Factories bigger than 2,000 square meters can handle big orders and meet your needs.
Here is what you should check when looking at industry references:
You should also ask for sample test results. Good suppliers share data about accuracy, heat control, and EMI compliance. They also give clear documents, like bills of materials and lists of parts. This honesty helps you trust the supplier and feel good about your choice.
Note: A supplier with strong industry references and good case studies gives you peace of mind. You know they can deliver quality products and help your business grow.
Balance Cost & Value
Total Cost
You need to look beyond the price tag when you choose an OEM VFD supplier. The total cost of ownership includes more than what you pay upfront. You spend money on maintenance, repairs, and energy every year. If you pick a supplier just because they offer the lowest price, you may pay more later. Poor-quality parts break down faster. You call for repairs more often. Your machines use more energy and waste money. For example, non-OEM pumps can be 10.25% less efficient than OEM ones. This difference can cost you $1,100 to $3,700 more each year for every pump, depending on how much you use them. You save money in the long run when you choose a supplier who offers high-quality products and reliable service.
Tip: Always ask about maintenance costs and energy efficiency before you decide. A good supplier helps you lower your total cost over time.
Long-Term Value
You should think about what you get from your supplier over many years. Long-term value means more than just the first sale. Top suppliers give you support, maintenance, and warranties. They help you keep your system running well. They also invest in new technology so your machines stay up-to-date.
You get more value when your supplier offers extra features. Look for these benefits:
IoT tools for remote monitoring and quick fixes
Digital twin technology for safe system testing
Energy-saving programs and green designs
Note: Suppliers who care about long-term value help your business grow. You spend less on repairs and upgrades. You also get better results from your machines year after year.
You can stop expensive mistakes if you follow some important steps when picking an OEM VFD supplier. First, think about what your machines need and what your business wants. Next, see if the products work well with your system and check if the supplier has the right certificates. Make sure the supplier gives good help and tells the truth. Read what other customers say and see if the supplier gives good value for a long time. You can use Canroon’s knowledge to help you. Careful choices keep your business safe and your machines working well.
