Senho Industrial Chiller, China

There was one customer once told me about his opinion:"We buy industrial chiller from China because we know it is not expensive, so there is no reason a Chinese brand offer me high price, I won't accept it." Well, we always think that China are not capable of making top quality products. Honestly, I personally thought the same 3-5 years ago. But in recent years, things has obviously changed. I'm not saying that all Chinese manufacturers just hop into the rank of TOP brand, I am saying that China has a different economy environment than before.  You can easily learn from your Chinese supplier that  cost of materials are rising for the past few months. And why is that? Because Chinese government are being more strict to manufacturers on environmental clauses, which apparently had led quite a few suppliers into shutting down. Those suppliers, in my opinion, are typical Chinese business for the past 10-20 years. They don't have high standard for production pr

As one of the most important parts in a chiller, the purpose of evaporator is to transfer the cooling energy from cold refrigerant(gas) to water or other coolant. There are three main types of evaporator for  industrial chillers , they are coil type, shell and tube type and plate type. Here we are comparing these three types of evaporators from aspects of  Heat Transfer Efficiency, Requirement for Water Quality, Convenience of Maintenance  and  Space Occupation. 1.     Heat Transfer Efficiency. Heat transfer efficiency is very important for a heat exchanger. Normally, plate type evaporator has the highest efficiency than others, because its more precise structure. Shell and tube type ranks second in this list, while coil type has relevantly the poorest efficiency amongst the three types of evaporators.  Heat efficiency needs to based on heat exchange area, higher efficiency means it can transfer more energy with less heat exchange area. On the other hand, if the effici

Air cooled or water cooled chiller, which is suitable for my case? This is a question put in front of many people. Here we will talk about the differences between them from these aspects: performance, installation, maintenance and cost. 1.    Performance Air cooled industrial chiller is with aluminum fin type condenser, which allows it to discharge the heat to the air. In other words, the heat is removed by the ambient air. Water cooled chiller is normally with shell and tube condenser. The heat from the chiller is removed by water that goes into and out from the condenser. As we know, for a chiller, if you can get lower condensing temperature, you can have better performance. Actually, the difference of condensing temperature is the reason of different performance between water cooled and air cooled chiller. In our daily life, if we want to cool something, for example a glass of hot water, do you prefer putting the glass in a container with cold water or put it in front

Although Senho Chiller provides installation guidance service, if you already have some experiences in chiller operation and installation, you can choose to proceed by yourself to save labor cost and time. But first we need to stop thinking that chiller installation is simple enough, that we just need to connect it to electricity and water, it can just work well by itself. Pay attention to a few more details, the chiller will return you better performance and longer service life. Here are the precautions that you need to know before proceed: 1.     Selection of installation location. For air cooled chillers, we need an open space with good ventilation. Make sure there is no barriers or walls within 1m around it, otherwise there will be trouble for air flow and heat dissipation. The point is we need to make sure the heat out from the chiller can be removed outside, instead of circulating within a small space. The distance to block also ensures space for maintenance. If
