When purchasing a mold temperature machine, many people may have doubts about the type, not knowing whether to buy a water temperature machine or an oil temperature machine. Therefore, the editor will explain the difference between the two, which may help everyone make the right choice faster.

Difference 1: In terms of temperature control range, the oil temperature machine has a temperature control range of approximately 200 to 350 degrees depending on the quality, while the water temperature machine has a temperature control range of 120 to 180 degrees;

Difference 2: The water temperature machine uses water as a heat transfer medium, so the cleaning cost is lower during use, while the oil temperature machine uses heat transfer oil as a heat transfer medium, which has a higher cost;

Water temperature machine and oil temperature machine are two different types of mold temperature machines based on heat transfer media. Water or high-temperature thermal oil, as a circulating carrier, has its own characteristics and application advantages. What are the advantages and disadvantages of a water temperature machine and an oil temperature machine? As end users, how do we determine and choose which device is more suitable for our needs? What is the basis for selection?

We first analyzed the working principle. Although they use different heat transfer media, their basic working principles are similar. After the application device comes out, the heat transfer oil (if it is a water temperature machine, i.e. circulating water) enters the oil heat machine. The controller determines whether to heat or cool the unit based on the feedback signal from the temperature sensor installed in the pipeline and the system set temperature, and controls the solenoid valve through the connection between the heat pipe and cooling water. The hot oil is heated or cooled, and the pump continues to deliver the heat transfer oil to the pipe inlet of the temperature controlled application device. Therefore, there is not much difference between the operating process and the principle.

When purchasing a mold temperature machine, do you want to buy a water temperature machine or an oil temperature machine?

The heat transfer medium of a water heater is water. As for heat transfer oil, water has the characteristics of high specific heat transfer and rapid heat transfer. Therefore, under the same application conditions, the heat transfer efficiency of the device will be better. In addition, the water temperature machine has advantages such as easy to pull, no pollution, low price, and simple operation and maintenance. Its disadvantage is that the temperature control range is narrow, with a control temperature of 180 degrees, and the oil temperature machine can reach 350 degrees. Another reason is that due to pressure heating, the device has certain pressure requirements for the pipeline system.

The heat transfer medium of the oil temperature machine is high-temperature heat transfer oil. Heat transfer oil has the characteristics of good thermal stability and wide temperature control range. Due to the atmospheric heating method, the pressure level of the pipeline and temperature control device of the device is greatly reduced. Of course, oil temperature machines also have their drawbacks, such as higher prices, slower heat transfer speed, and higher maintenance costs compared to water temperature machines. Especially in some non-standard thermal oil pipelines, the operation method is prone to coking and carbon removal. Location, replacement, and cleaning can all be troublesome, and changing heat oil often incurs a lot of costs.

So, how do we decide whether to choose a water temperature machine or an oil temperature machine? In fact, we must consider the following three aspects:

Firstly, control the temperature of the equipment

Secondly. Pipeline systems, such as pressure levels

In the third place. Environmental requirements for application devices

Co selection suggestion:

-If the temperature is below 100 degrees, you can choose a 120 degree water temperature machine or a 200 degree oil temperature machine.

-The temperature is between 100 and 170 degrees, and you can choose a 180 degree temperature machine or a 20 degree temperature machine
