A "reefer truck," then, is a semi pulling a refrigerated trailer, designed to haul perishable goods. These trailers differ from cooling vans, which are just insulated and vented. What makes a reefer trailer different? Reefers include an active cooling system. Thus, you can transport frozen as well as refrigerated freight. A reefer could also be temperature adjusted to haul heated goods as well. However, this is much less common. You can find reefers using a couple of different cooling methods. You may see both diesel-powered generators and cryogenic cooling systems. Let's take a closer look at exactly how trailer cooling works.   How Reefer Units Work   Reefer units operate on a  closed system .

Buying ski/snowboard outerwear  comes with many confusing technical numbers such as 15,000 Waterproof or 10k Breathability. There’s also lots of other strange terms such as wrist gaiters & fully taped seams. Here’s a simple explanation on what it all means and how you should select your jackets/pants:   1) Breathability Rating This is how much moisture can escape from your  ski jackets /pants. Higher is better. Breathability rating usually starts at about 5,000 and goes as high as 30k+. What breathability rating do I need? You’ll typically want a minimum of 10k breathability rating. I find that going below 10k breathability results in your jacket/pants holding in too much sweat and moisture. Unless you ride for really short periods or never sweat, I wouldn’t go below 10k.     2) Seam Taping Seam taping describes how the waterproof tape has been placed over the stitches and seams of your clothing.

    Brake pads are also called brake pads. In the braking system of the car, the brake pad is the most critical safety part, and the brake pad plays a decisive role in the quality of all braking effects. The working principle of the brake is mainly from friction. The friction between the brake pad and the  brake disc   (drum) and the tire and the ground is used to convert the kinetic energy of the vehicle into the heat energy after friction, and the car is stopped. A good and efficient braking system must be able to provide stable, sufficient and controllable braking force, and have good hydraulic transmission and heat dissipation capabilities to ensure that the force exerted by the driver from the brake pedal can be fully and effectively transmitted to the master cylinder And each sub-pump, and avoid hydraulic failure and brake recession caused by high heat. The brake system on the car is divided into two categories: disc and drum, but in addition to the cost advant...
