Construction workers, or people working in boiler rooms, foundries, power plants or welding shops, are exposed to high temperatures daily. To avoid suffering from heat stress, and to help improve their productivity, these workers should turn to cooling vests.
There are different types of cooling vests on the market, but some are more convenient than others. Here is how you can choose the right personal air cooler for your needs.
1. Learn more about the different types of cooling vests available
Before you can find the right personal air cooler for you, you need to learn more about what is offered on the market. Personal air coolers are a popular option, and provide consistent cooling thanks to a vortex tube unit that circulates cool air through the vest. Other types of cooling vests involve cool water flowing through the vest with the help of a pump.
Evaporative cooling vests are vests that you have to wet with cold water before wearing them. They will help you stay cool while the water evaporates. Then, they will need to come in contact with more cold water, so they are not the best choice if you don’t have a reliable access to water during your work days.
Other vests use cold pack inserts to help workers stay cool, while others use phase change material packets as a cooling component. Those phase change materials can either be non-toxic, or toxic, so read all the details carefully if you are interested in this type of vest.
2. Personal air coolers can restrict your movements
Are you sitting or standing still for long periods of time, or do you need a cooling vest that does not restrict your movements? Some types of personal air coolers will allow a full range of motion, while others will lose their efficiency if the person wearing them moves too much.
Pay attention to this detail as you take a closer look at different models of personal cooling vests.
3. Some cooling vests are not meant to be worn under other clothing
Some cooling vests can be worn under welding aprons, or other protective clothing. Other types of cooling vests can be worn directly against the skin, while others must be worn over another layer of clothing to avoid cold burns.
Choose a personal air cooler that works best with the way you dress when you are working in hot environments.
4. The effectiveness of some personal cooling vests decreases with time
Some cooling vests provide continuous and consistent cooling. A personal air cooler or a cool flow cooling vest, for example, should keep you cool and comfortable for a long period of time, and they are generally more expensive than other types of cooling vests.
The effectiveness of other types of cooling vests, such as evaporative cooling vests or vests cooled with phase change material, will decrease with time. Those cooling vests are a better choice if you don’t expect to be needing them for long periods of time, as they are usually more affordable.
5. Some types of personal air coolers can also distribute heated air
Finally, did you know that some types of personal air coolers could also distribute heated air? This is convenient if you sometimes have to work in cold environments, as you will be able to use the same personal air cooler to keep yourself warm and comfortable.
Now that you have determined your needs and your expectations, it should be easier to find the right personal air cooler for your situation and your budget.
