With a growing emphasis on health ,the myriad advantages of cold plunges have become widely recognized—ranging from alleviating muscle pain to enhancing recovery and boosting sports performance. Consequently, cold plunges have seamlessly integrated into the fabric of our daily lives.Cold Chiller, a dedicated manufacturer of cold plunge chillers, aims to address and summarize the common challenges that users may encounter in the utilization of water chillers.

The manuals that come with cold plunge chillers contain the manufacturer’s guidelines for operating them properly. Users must follow these guidelines because poor operating practices can adversely affect equipment efficiency and service life. Although these cooling systems may continue to function regardless of improper operation, it is worth noting that these systems are more prone to problems. In order to reduce this situation, special instructions for use and how to maintain the cold plunge chiller can be noted. Or follow us on youtube


the content will be updated to tell them how to use it correctly, so that they can more clearly regulate the correct use and protect the cold immersion chiller.

If the cold plunge chiller is not cooling, it may be because there is no coolant or there is not enough refrigerant capacity. Sometimes we receive feedback from customers that everything in the water cold plunge chiller is working normally, there is no strange noise, the water flow in and out of the water inlet is normal, there is no blockage, the water pump and adapter are also working normally, and nothing unusual can be seen. Sometimes it may be a problem with the coolant inside the cold plunge chiller. There may not be enough coolant to achieve the cooling effect.Another possibility is that the coolant is leaking. During the long-distance transportation of the cold plunge chiller, violent transportation may cause collision or compression of the cold plunge chiller, which may cause the pipes containing the coolant to become loose or ruptured, causing the coolant to leak and fail to meet the required cooling capacity, so there is no way to cool the cold plunge chiller. At this time, the coolant needs to be added again.

1)Ventilation is important but most often ignored

There are actually many factors responsible for the slow cooling speed. If everything in the cold plunge chiller seems to be working normally, but the cooling speed is slow, it may be related to the ventilation effect. The ventilation effect is relatively easy to be ignored by users. We recommend that customers place the cold plunge chiller in a place with good ventilation. The better the ventilation, the better the cooling effect, and the faster the cooling speed will be. It is best to keep the cold plunge chiller at least one meter away from walls or other objects. Do not block the cold plunge chiller to dissipate the heat inside. When cooling, a good space is needed inside the cold plunge chiller to quickly dissipate heat. This way the cooling effect will be better. In particular, users who use it indoors need to pay attention. We often see customers use it in the bathroom. The environment itself is relatively small, and the ventilation effect is limited. Later, we suggested that the customer place the cold plunge chiller one meter away from the wall, and the cooling effect and speed would be much better.Therefore, the ventilation effect is a factor that deserves attention for the slow cooling effect.We need to tell customers the importance of usage environment.

2)Problems with the compressor inside the cold plunge chiller will also affect the cooling speed.

At this time, you can check whether the wiring of the compressor in the inner tank is loose, and whether the air at the vent of the cold plunge chiller is cold or hot. It is recommended to use a better quality compressor, but under normal circumstances, the chance of compressor damage smaller.

The blockage of the water inlet and outlet of the cold plunge chiller and the blockage caused by the filter not being cleaned will affect the normal operation of the cold plunge chiller. Some users like to use the ice bath tub outdoors. Some fallen leaves will fall on the cold plunge tub, or there may be some weeds in the user’s garden. If the user’s feet touch the grass, they will enter the cold plunge tub with the user. It is very likely that Will cause blockage of water inlet and outlet. Therefore, users should pay attention to ensure that the water in the bathtub is clean as much as possible, so as to reduce the blockage of the water inlet and outlet.The filter also needs to be cleaned in time, and the filter core can be replaced regularly. Users can judge how often to clean the filter and replace the filter core based on local water quality and frequency of ice bath tub use.If it is used frequently, we generally recommend that customers remove the filter and clean it once a week, and the filter core can be replaced every six months. Customers can also observe whether the filter becomes dirty during use, and it can be removed and cleaned at any time. We also provide customers with a removable metal filter at the water inlet of the bathtub. It is very convenient for customers to disassemble. It only takes a minute for customers to clean the cold plunge tub every time they use it, so as to ensure that the water inlet and outlet will not be blocked.For customers who purchase our cold plunge chillers, we will provide them with an additional filter core for replacement.Users can ensure that the water quality is clean and clean it regularly to avoid the water cold plunge chiller becoming clogged and not working.

When the cold plunge chiller is at low temperature, condensed water will be discharged and flow to the floor. Sometimes this situation is mistaken for water leakage inside the cold plunge chiller. In fact, it is not the case. Condensation water does appear in the cold plunge chiller at low temperatures, including the pipes. You can see that there is condensation water on it, but this needs to be addressed. After practical testing, all the internal structural pipes of the cold plunge chiller in our factory are wrapped with insulation cotton. After low-temperature testing, our cold plunge chiller did not discharge condensed water at low temperatures (3°C), and we added additional water inside the cold plunge chiller. A pipe is specially designed to drain the condensed water, so that the condensed water will not flow into the inside of the cold plunge chiller. And the thermal insulation cotton we added can also be used for good insulation, allowing the cold plunge chiller to reduce losses when cooling or heating, so that the cooling or heating speed will be faster.

When the water pump is empty, it actually means that there is no water flowing into the pipe. At this time, you need to pay attention to the location of the pipe connecting the ice bath tub and the water cold plunge chiller. First, the size of the pipe connection should not be too long, and try to ensure that the pipe is straight rather than curved. Some users like to place the cold plunge chiller in the ice bath tub. The back side feels more beautiful, but this may also be caused by the bending of the pipe and the lack of normal flow of water, which causes the water pump to be evacuated. And the position of the water inlet is preferably higher than that of the cold plunge chiller. This position forms a natural gap, making it easier for the water flow to enter the inside of the cold plunge chiller pipe and then into the water pump. In this way, the water flow can be smooth and the water pump can work well. If the water pump is emptying, you need to shut down the cold plunge chiller first to avoid damaging the water pump due to long-term pumping. You need to fill the water inlet of the cold plunge tub with water, let the pipe water inside the cold plunge chiller enter, and the water slowly circulates, and then turn on the cold plunge chiller.

Leakage at the pipe interfaces inside the cold plunge chiller and rust on some spare parts are also common problems. For example, if some parts are not made of stainless steel, under the action of condensation water or in a humid climate, the cold plunge chiller will be oxidized and rusted after being used for a period of time. Water leakage actually means that the pipes and fittings are made of plastic or are of poor quality, causing water leakage problems.Moreover, the pipe joints are not tightened enough, and some suppliers even use glue to connect the pipes, which may not only easily cause water leakage, but also be difficult to disassemble. All pipes and fitting interfaces inside the cold plunge chiller in our factory are made of metal, which will not cause rust problems and are very easy to disassemble. There are also sealing rubber rings at the interfaces to avoid water leakage problems. Of course, the cause of water leakage may also be that the pipes became loose during transportation. The user can solve the problem by tightening the pipes after inspection.

There are several possible reasons why your cold plunge chiller may not start. Some common reasons include:Electrical Problems, If there is a problem with the power supply, such as a loose wire, a blown fuse, or a tripped circuit breaker, the cold plunge chiller may not start.Control system issues, such as a damaged control panel or thermostat, may prevent the cold plunge chiller from starting.Problems with the refrigerant system, such as low refrigerant levels or leaks, may prevent the cold plunge chiller from starting.

Problems with the compressor, such as a motor failure or a stuck compressor, may prevent the cold plunge chiller from starting.Mechanical Problems: If there is a mechanical problem, such as a broken part or a damaged belt, the cold plunge chiller may not start.
