Why DOLUYO Commercial Refrigeration Are Expensive
This post aims to demonstrate why DOLUYO’s commercial refrigeration equipment are more expensive compare to other manufacturer in China. Also how to choose a reliable Chinese commercial refrigeration manufacturer. I have summerized into 6 points.
Welcome to our quick guide on understanding the value behind DOLUYO’s commercial refrigeration equipment. Many people look towards Chinese manufacturers for affordable options without deep knowledge of the market or experience in dealing with local manufacturers. It's common to compare prices extensively and choose products that seem to offer a balance between cost and profit potential. However, this approach can be particularly misguided in the realm of refrigeration equipment.
A critical question to ask when selecting commercial refrigeration is about the type of compressor being used. Often, manufacturers may tout the use of a Copeland compressor, which initially sounds impressive given their reputation for quality. Yet, what's frequently omitted is that these are Copeland ZW series compressors, which are designed for heat pumps and are not capable of cooling below 0 degrees Celsius. Such compressors, if used persistently at low temperatures, may have a significantly reduced lifespan. Therefore, understanding the specific model of compressor is vital when choosing commercial refrigeration equipment.
If your requirements do not demand the highest quality of refrigeration, then our products might not align with your needs. I suggest you to close this page, and I won’t try to persuade you to use our product cause you are not our target client.
However, for those in search of premium quality, let's delve into why Doluyo's offerings are priced at a premium in the market.
Since its inception in 2000, Doluyo has accumulated 24 years of experience in the industry, continually learning from past mistakes and enhancing our technology. We've invested million dollars in research and development to pioneer the use of hot gas defrost technology and integrate all components within the condensing unit. Our units are equipped with four-way valves, electronic expansion valves (EEV), and an advanced control system, including precharged refrigerant, simplifying the installation process for contractors.
Our commitment to quality is unmatched in the Chinese market. Here's a closer look at what sets our products apart, and why they command a higher price:
Exclusive Use of High-End Components: We incorporate EBM-PAPST/ZIEHL-ABEGG axial fans in our air coolers and condensing units above 12hp.
So lots of people ask why our products are so expensive in 8/10/12/15hp. Look at how much is the ZIEHL-ABEGG FN080-SDQ.6N.V7P5 axial fan, this is what we use on these model, contributing to the higher cost but significantly improving reliability and efficiency.
In july, we will have a new model that will fit 8/10hp condensing unit. This is the teaser. The price will come down a lot, giving you a lot more option on it. (new model shown on below)
2. Transparency in Materials: Unlike others, we openly share that we use SANHUA components for critical parts like the EEV and four-way valve, ensuring durability and performance. If you compare to other manufacturer they would not tell you what brand they use because it is cheap and easily broken.
3. Customizable Compressor Options: While we primarily use Invotech compressors, known for their innovative application of Copeland's technology, we offer the option to switch to Copeland compressors for those who prefer it, at an additional cost. Invotech is also a sophisticated company in China with many years experience in compressor. The crew was originally from Copeland company. Later they decide to move out and build a new company call invotech.
4. Quality Air Coolers: Our air coolers also benefit from the reliability of international brands like EBM-PAPST/ZIEHL-ABEGG, enhancing stability and lifespan.
5. Superior Heat Exchange Efficiency: Our air coolers feature a fin spacing of only 7mm, packing more fins into a smaller volume, leading to quieter operation and more efficient heat exchange, in contrast to competitors who may emphasize the size of their heat exchangers without disclosing the actual volume of heat exchange.
Some of the factory will compare their heat exchanger area with ours especially Meluck & other companies from ZHEJIANG. They are telling you that they have much more heat exchange area than ours. But in fact, they avoid speaking their heat exchange volumn. If you ask them what is the heat exchange volume they will silence and choose not to answer. I gonna show you with one simple image. In the image, you can see their air cooler is bigger than ours in dimension, but in fact they making the area larger so that they can save more fin and save more cost, because as client you can't see the inside of the air cooler and so you don't know what is the heat exchange volume. We use much more fin when comparing heat exchange volumn, so that we can make the air cooler smaller, the axial fan spin speed would lower and thus noise is lesser. You can't expect cost of our product lower but you will know our product is very cost-effective.
This is giving you a quick idea of heat exchange area and heat exchange volume concept. The value itself does not represent the actual value in Air cooler
6. Innovative Use of Inner Grooved Copper Pipes Inside Air Cooler: This design enhances refrigerant flow, allowing for faster temperature reduction in cold rooms, despite the higher cost of these materials.
In summary, Doluyo's commitment to quality, innovation, and transparency results in higher costs but assures unmatched quality in commercial refrigeration. Our dedication to excellence is what sets our products apart and justifies their premium pricing."
