Senho Industrial Chiller, China

Senho Machinery supplies glycol chiller with minimum temperature -35℃, including air-cooled glycol chiller, water-cooled glycol chiller, scroll glycol chiller and screw glycol chiller. Glycol chillers are widely applied in industries such as cold room, ice rink, chemical, etc. Welcome to contact us for more details.

Chiller and cooling tower are both cooling equipments, but the working principle is quite different. If we compare them with our daily used home appliances, a chiller is like air conditioner, while a cooling tower is like a fan. You can easily see the difference: air conditioner can bring the temperature lower than ambient, while fan can not.  In industrial process, you can also easily decide what is suitable for you. If your process requires water temperature lower than the ambient, then only chiller unit can meet the requirement. For example, you need cooling water temperature around 15℃, but your ambient temperature is not lower than 15℃, then cooling tower can not manage this case. We talked about ambient temperature instead of wet bulb temperature, because wet bulb temperature is the most ideal result that a cooling tower can get, in most cases, cooling tower can only cool the water down to ambient temperature.  Sometimes some customer contact us and inquire about industri

As a manufacturer of industrial cooling equipment, it is our duty to provide a suitable and correct solution for our customers. Here is a brief article for sizing an  industrial chiller . Click to view this article: what do we need to know when size an industrial chiller?

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
