Portable Infrared Heaters – An Introduction To Infrared Heaters

One of the best, most highly efficient sources of heating is the portable infra-red heaters. These types of heaters can be used for many different situations that require heating. They can be used for such applications as heating commercial and industrial buildings as well as area and spot heating. They have also been used for process heating ovens as well as broiling commercial food.

It has been proven that using such heaters can dramatically lower energy costs for many commercial buildings. One manufacture installed their product into one of there warehouses for a single heating season. Prior to the installation the energy costs were up to $106,000 per year but after the use of the heaters the energy cost dropped to just $27,000 per year. That is a huge savings that cannot be ignored. With statistics like this, portable infra-red heaters practically sell themselves. It shows that the money paid for the heaters will be made back many times over in just the first year of using such heaters.

There are more and more companies as well as people jumping on the band wagon of portable infrared heaters as they realize the many benefits that the heaters can provide. Generally, most people and companies can expect to see a 30 to 50% drop in their fuel consumption with a portable infrared heater then with the typical conventional heating systems.

How Do Portable Infrared Heaters Work

So just how do these wonders of man kind work? An infrared heater is a unit which has a higher temperature then bodies of substance around it. It transfers its energy to things that have lower temperature by electromagnetic radiation. It depends on the temperature of the body that is emitting the energy as to what the wavelength of the infrared radiation will be. It can range from 780 nm to 1nm. Amazingly enough, there does not need to be a medium or contact between the two items for the energy to transfer.

There is a classification of the infrared heaters for the wavelength bands where the emission of energy is concerned. 780 nm to 1400 nm is the range for the short or near infrared. These are named bright, as the emitters actually emit a glare that is visible to people. 1400 nm to 3000 nm is considered medium infrared and dark emitters or far infrared is for everything that is over 3000 nm.

Benefits of Portable Infrared Heaters

There are many benefits to using portable infrared heaters. One of the top reasons is the efficiency of the infrared heaters. Technically the efficiency of these heaters is considered to be 100% as it takes electrical energy and converts nearly 100% of it to heat in the filament. Once the heat is generated, the filament then emits the heat by the infrared radiation to the object to be heated. This is done either by a reflector or it can be done directly to the object. There is a bit of energy that is lost during this process but it doesn’t take away from the performance of the heater.

An infrared heater counts on matching up the ranges of wavelengths with the absorption range of the material or matter that is going to be heated. A good example of this is would be the absorption range for water, which reaches its crest or peak at around 3000 nm. So what exactly does that mean? It means that the carbon infrared heaters (with medium wave emission) are absorbed better with coatings that are water or water based rather than the short wave infrared radiation or NIR. This is also the same for various types of plastics such as polyethylene or even PVC. Both of these plastics have an absorption peak at around 3500 nm. It is important o be sure that you get the right range of infrared for the type of object that you are heating. Some metals will only absorb with the short wave and others with the medium and far infrared. So you need to be sure that you check to make sure you have the right range for your needs. The more you match it up the more efficient your heater will be.

Portable infrared heaters can be used to cure coating as well as to heat plastic prior to shaping or forming it. They can be used to weld plastic and to process glass. You can also use then for browning your food and to cook the food as well. These types of heaters have also been used to keep animals warm in places such as zoos and vet clinics. There are many used for the portable infrared heater. You can make your choice of which one to use.
