Friends who don't know much about the temperature control industry like to call the water temperature machine and the oil temperature machine collectively called the mold temperature machine, in fact, the two have obvious differences, not easy to confuse. If you want to ask, what is the difference between oil temperature machine and water temperature machine, you can answer it from the heat transfer medium used in the two, the temperature control range and the heat transfer efficiency, please take a look.
The difference between oil temperature machine and water temperature machine 1: The heat transfer medium used is different.
The oil temperature machine is an oil-type mold temperature machine, and the heat transfer medium used is a high-temperature heat transfer oil with a very high ignition point (specially treated heat transfer oil). The water temperature machine is a water-type mold temperature machine, and the heat transfer medium used is environmentally friendly and clean water, which is easy to use and pollution-free.
The difference between oil temperature machine and water temperature machine 2: the temperature control range is different.
The temperature control range of the oil temperature machine is 400 at room temperature (up to high temperature under normal pressure), common models are 200 standard type, 250 high temperature type, 300 high temperature type, 350 ultra-high temperature type, customized models up to 400 ultra-high temperature type.
The temperature control range of the water temperature machine is 180 at room temperature (the current pipeline pressurization technology can reach high temperatures), and the common models are 120 standard type, 150 high temperature type, and 180 ultra-high temperature type.
The difference in the temperature control range between the two is due to the fact that the characteristics of the heat transfer media used are completely different. Heat transfer oil has extremely high temperature resistance, good thermal stability, wide temperature control range, can be heated to 350 at room temperature, special models can reach 400, for the demand for more than 200 industrial production, oil temperature machine is very widely used, has irreplaceable advantages. The water temperature machine is limited by the low boiling point of water, and it is not easy to obtain an ultra-high temperature boiling point of 180 under the current mature pipeline pressurization technology and safety protection, and at the same time, because of the cleanliness and environmental protection of water resources, convenient access and pollution-free, industrial temperature control below 180 is more favored by industrial production.
The difference between oil temperature machine and water temperature machine 3: the heat transfer efficiency is different.
The heating mode of the oil temperature machine is to continuously heat the heat conduction oil through the heater, so as to have fast heat transfer efficiency and good thermal insulation performance. The water temperature machine is to directly heat the water through the heater, the specific heat capacity of the water is larger, it can heat up quickly, compared with the heat transfer oil, the heat transfer efficiency is higher and faster, and the relative heat retention is not as good as the oil temperature machine. Under the same application conditions, the heat transfer efficiency of the water temperature machine is better than that of the oil temperature machine.
