The Importance of Diesel Heater Clamps

 

It’s necessary and pleasant to have a diesel air heater installed to spend the freezing cold winter.

However, many customers would complain that they smell the exhaust gas inside the cabin after the heater is turned on for a while. It’s absolutely no good.

As we all know, the diesel exhaust gas contains harmful matters which can have adverse health effects. Among all of those matters, carbon monoxide(CO) is the most dangerous one.

 

 

It can cause headache, dizziness, weakness. Long-term exposures can lead to chronic, more serious health problems such as cardiovascular disease, cardiopulmonary disease, and lung cancer.

The following are classes of chemical compounds that have been found in diesel exhaust.

Another harmful one would be the particulates. They are existed because of incomplete combustion. Exposure to diesel exhaust and diesel particulate matter (DPM) has already become an occupational hazard.

For over 10 years, concerns have been raised in the USA regarding children’s exposure to DPM as they ride diesel-powered school buses to and from school.

Diesel air heaters can be installed into many vehicles such as cars, trucks, buses, RVs, and boats etc. Mostly, people would install the heater inside the cabin.

The purpose of people buying a diesel heater is to enjoy warmth during the freezing cold winter, and we certainly don’t want anything harmful mixed in the warm air. However, it’s highly possible.

 

It’s possible because the heater might have the poor quality. The manufacturers of those awful heaters don’t care about people’s health but only profits.

In this article, I’m not going to talk about all the parts that could cause safety problems. Today I will just focus on one, a small part which is a key of blocking hidden dangers outside, and the part is called clamp.

It is a very small part in a diesel heater package. However, it can be the most important one.

VVKB Diesel Heater Clamps

 VVKB Diesel Heater Clamps  

A clamp is a fastening device used to hold or secure objects tightly together to prevent movement or separation through the application of inward pressure.

Stainless steel pipe clamps are a practical method for holding cables, hoses, pipes, and tubes in place securely. Not only do they prevent leakages, they are also considered to be a cost-efficient investment!

Three Kinds of Clamps

From the picture above, we can see three kinds of clamps. They all can be used to secure the exhaust pipe of diesel heaters. But I believe readers can know which one is best just by looking at their appearances—the middle one.

Of course we can’t judge something just by the outlook. Let’s take a further study.

The clamp in the middle is from VVKB and it’s made of stainless steel, which has high corrosion resistance. The thickness of this clamp is 1.2 millimeter, so it has high-strength clamping force to connect the exhaust pipe and exhaust muffler.

In this way, it can avoid the loose exhaust pipe connection, and no harmful exhaust gas can enter the cabin.

The threaded end is directly fixed on the clamp, which is convenient for the customers to handle. And the stainless steel screw works very well, and with stainless steel flat pad and spring pad, the screw won’t be loose due to the vibration(we can see from the picture that the clamp totally wraps the pipe).

The screw type is A2-70, it can stand a strength of extension to 700MPa.

It’s proud to say that VVKB is using this heavy-type clamp. We are now more confident and are accepting more orders gradually.

Our dealers have many good words about this clamp, and we are happy they like it, we are also happy to see their business growing.

Actually, Webasto and Eberspacher are also using this heavy kind of clamp, and below is a picture:

Both of them are well known brands and VVKB respect them very much. They also make good heaters and put customers’ health and safety in the first place(another reason to use this clamp).
Not to brag, but VVKB’s clamp is better than that in the above pic. Firstly, the appearance looks more neat and VVKB also provides the flat pad and the spring pad so that the screw can be better protected, and the force can be higher.

However, the second clamp below is made of stainless steel wire. It looks very simple and It’s ok to use such clamp to fasten the pipe but the safety level is not as good as the first one:

The clamping force of this kind of clamp is generated between the screw and the elbow. It cannot withstand high tensile forces because of its structure. Excessive tension will straighten the clamp, and make it lose its original function.

And the worst one is this clamp(try to avoid this kind if you are going yo buy a heater):

It is made of thin stainless steel and the screw is made of iron. The clamping force is generated by iron screw’s movement on the small protrusion.

If there is too much tightening force, the clamp will fail. It has the smallest strength among these three. And in the long-term use, the iron screw will oxidize and rust. It will greatly reduce its service life.

Unfortunately, it’s very common to see this kind of clamp on some e-commerce retail websites. Some manufacturers from China try their best to cut off the money from materials.

They are not producing parts to serve customers but want to make as much money as possible. Customers should be careful about that.

It’s true that those heaters are very cheap, but you might buy it at the risk of your life. Just think twice, the danger of exhaust is no kidding.

Well, it might be good to use such clamp to secure hoses, but it’s definitely no good on pipes.

Now let’s compare these three clamps by weight. Readers can see the differences below. The first clamp is has the highest weight: 32.32 grams.

It also equals the weight of the other two clamps combined(21.72 grams and 11.52 grams). And that definitely proves the good quality.

From all the points above, I believe readers know how to find a good heater. It’s safe to say if a seller includes the good clamp in the heater package, the heater can be trusted.

Of course, customers should ask more before they hit the purchase button. Ask as many questions as possible.

If you have already purchased a heater and you now want to change the clamp to ours, you may send inquiries to info@vvkb.com or directly go to our retail website to purchase! Here is the link: www.rvheater.com For dealers, we provide better prices to help their business grow.

And dealers may also help to change the clamps so that their customers can be free from the danger caused by the exhaust.

As we always say—small problem makes big problem. If we gradually fix the small problem one by one, the product would be better and customers will like the product better. That’s how a company exist for long.

However, if we ignore those small problems, they might accumulate into big ones and get back on us real hard. Think about this, what if a poor quality heater takes somebody’s life?

And the company produces the heater will face real big problems, it happens just because of a small part—clamp.

Pay attention to the quality but not profits. Remember, quality can bring more profits.
