10 Best Hydrocollator Moist Heat Pack

Physical fitness is one thing everyone struggles with today. Especially in this era of white-collar jobs and people are rarely getting enough time to exercise. Most people have resulted in house exercise and therapeutic exercise. One of the pieces of equipment helping put people back on the healthy path is the hydrocollator pack. 

Hydrocollator pack is kind of a medical tool used alongside hydrocollator unit. It contains natural fillings such a bentonite clay and it’s heated with a thermostatically controlled liquid. The concept of hydrocollators was first introduced by the Chattanooga Pharmaceutical Company in 1947. The heating packs are immersed in the hot water and heated up to approximately 160 degrees. The pads are covered with several layers of towels then applied on the body part and left in place for several minutes for the heat to penetrate the body tissues.

The main function of hydrocollator pack is to relieve various forms of body pains especially those related to muscles and joints. It works well for people struggling with arthritis, painful tissues, joints, and strains. Hydrocollator pack does this by increasing the temperatures of the affected tissue thus relaxing the muscle spasms and decongesting them to boost flexibility. It is commonly found with sports trainers, physical therapists, and kinesiologists. Hydrocollator pack helps to increase the rate of blood circulation thus speeding up the healing process of injured tissues and muscles.

What is Hydrocollator Used For?

Hydrocollator is used for heating the packs whenever a patient is referred for a moist, penetrating heat treatment. Moisture accelerates the rate of heat penetration into the muscle and skin layers to alleviate pain, relax the muscle and joints. The heating also leads to increased blood flow which is necessary for a speedy recovery of affected parts. You’ll find a hydrocollator with physical therapists and other medical practitioners.

How Do You Use a Hydrocollator Pack?

Hydrocollator pack has several uses on the human body. You can use it to relieve body pain or as part of general body therapy. To use it, first immerse in the hydrocollator for heating. The heating process should take approximately 20 minutes to raise the temperatures up to at least 160 degrees.

After heating, wrap the pack with several layers of towels preferably five. Then, once you are sure there are no exposed parts, you place it on the affected part of your body could be a leg, muscle, or joint. Leave it in place for like thirty minutes. If the part was aching, you should feel the effects by this time.

On the other hand, if you were carrying out massage, remove the pack, and then start the massage work. The packs help to relax the muscle and make the massage work easier. Once you are done with the pack, store it appropriately to ensure it doesn’t dry up.

How Does a Hydrocollator Work?

Hydrocollators are thermostatic heating devices used for physical therapy. They are made of stainless steel and can be either mobile or stationary. Whether stationary or mobile, hydrocollators are used to heat Bentonite-filled heat packs to a temperature of about 160 degrees. They have a hydraulic capillary thermostat responsible for ensuring that the packs are evenly heated. The function of insulated stainless steel is to guarantee a long life while insulation helps to prevent heat loss. It’s a way of preserving energy while preventing patients from burning.

A single hydrocollator can hold up to a minimum of four packs. This ensures that there are always readily available packs whenever needed. Since the packs are made of natural minerals, they can hold heat for as long as 30 minutes. The good thing is that they are in different sizes to allow use on different parts of the body; legs, shoulders, neck, etc.

When you want to apply the packs, you can use the tongs to avoid burning. After removing them from the water, drain them properly, and then wrap them in several layers of towels. Packs should never be allowed to come into direct contact with a naked body. Once covered, place the pack on the affected body part and leave it in place for some time. The duration can range between 15 to 30 minutes.

If you buy new packs, the first thing should be soaking them for at least 20 minutes. The soaking helps to ready the minerals to be ready to absorb heat evenly. Otherwise, it may not work well.

As you would have it with all medical equipment, hydrocollator and packs require maintenance. First of all, after use, you should place the pack in a microwave to prevent it from drying up completely. Allowing them to dry can destroy the mineral content present thus reducing its efficiency. The other important thing to do is to ensure that you keep the hydrocollator sanitized by cleaning it at least once after two weeks. It helps to avoid contamination of the packs after using them for a long time.

There is also a safety precaution when using hydrocollator. To avoid accidental burns, if you want to move it around, it is advisable to drain the hot water. Even if you trip, you’ll be safe.

Key Considerations Before Buying Hydrocollator Pack


The heat retention capacity of a hydrocollator park is an important factor that you should consider. It determines the length of time the heat park will take to work on your aching part without becoming cold. The higher the heat retention capacity, the better results you get from the heat pack.

The heat pack should be easy to heat up but hard to lose heat. This helps to conserve energy. The source of your heat should also be in mind. For example, if you are using the hydrocollator, you should ensure that the pack will endure the heat without bursting.


The sizing of a heat pack determines the parts it can work on. Big heat packs are more versatile in their use because they can work on several body parts. Smaller sized packs have limited options because they can’t wrap some parts that are too big. For example, you can find a pack that can work on the neck but not the back or the shoulders. Therefore, you should choose the size of your hydrocollator pack carefully depending on where you want to use it. If you are looking for your personal item, a big one is advisable because you can use it on several parts of the body.

If you are looking for a clinic heat pack, going for customized products is more beneficial. They tend to work best on their specific organs or parts. In most cases, you find if a pack is meant for the neck it’ll fit properly round the neck.

Extra Features

Additional features on heat packers are crucial in the operation of these important items. Some of the essential additions are the temperature control settings and self-moisturizing features. The heat packs with temperature control settings make it easy to heat your pack as you can automate the process. They also help to keep the users safe whenever using the packs.

You should always aim at getting the product with the most features within your budget. The good thing is that there are several models with many features that you can find at a low cost. Some products come with wrappers which cut on the cost of buying a separate cover.

User Reviews

User reviews are very important whenever you are shopping for anything in today’s market. The reviews act as the eyes of the buyer as they represent the true sentiments of the people who have interacted with the product.

If you find a heat pack with more positive reviews, the chances are that the product will satisfy your needs. If it has many negative reviews, you better avoid it lest the next review will be yours.


The materials making up the interior and external parts of the heat pack are equally important. For example, most of the heat packs contain Bentonite clay which retains a lot of heat and the material lasts long. You should also consider the composition of the outside fabric. There are some heat packs made of quality cotton covers that are quality and can last several years. The good the quality of the external material, the more durable the heat pack will last. Some materials also are allergic and you should check to ensure if you are buying for yourself, they won’t affect you negatively.

Ease to Use

Go for a heat pack with an exhaustive user manual. This will enable you to operate it without any complications. Usability is even more important because a heat pack is a hot product that is placed on the body. Therefore, accuracy is very critical and a simple mistake can lead to serious burns.

What Is The Correct Temperature For A Hydrocollator?

Hydrocollators do not have a fixed temperature unit to operate at. Therefore, the best range for most units is between 160 to 165 degrees.

How Long Should A Hydrocollator Pack Be Utilized?

15 to 30 minutes are enough time for hydrocollator pack on the affected part. This time allows the heat to penetrate deep into the body tissues or the muscles to bring much-needed relief. If you don’t feel okay, you can as well take a new pack and administer it on the part.
