Dometic & Norcold Cooling Unit Pressure Video

This video shows the measurement of both temperature and pressure for Dometic and Norcold cooling units, it demonstrates how the Fridge Defend protects your RV Fridge.

RV Fridge Boiler

This video shows how pressure is related to temperature, by measuring the temperature of your Dometic or Norcold cooling unit the pressure is also controlled. The Fridge Defend by ARP saves you money by preventing the boiler temperatures from becoming excessive.

The following photo is a failed RV fridge boiler. Please note that corrosion clearly is an issue for this fridge which failed. Please see following links to see how forensic engineers have confirmed that the ARP is the solution to RV fridge problems:

After viewing the video, please note that corrosion of the fridge is found to be a major problem. Please see following link and view what the "forensic engineer" stated reguarding corrosion.

The following link has a video of how the boiler fails.

What is the Pressure Issue Anyway?

As is stated in the video above the pressure within the cooling unit controls the temperature at which the water will boil within the RV cooling unit. The water should never boil in your cooling unit! When the water boils in the RV cooling unit; damage occurs, this damage cannot be reversed once started. The above video shows how the Fridge Defend Control protects your cooling unit by keeping the temperatures in check.

Putting it all Together

Norcold 1200 Boiler Failure

This photo shows the damage from the fluids boiling in the cooling unit of your fridge. Boiling produces pitting in your cooling unit just as it does in your cooking pans, this damage is called cavitation pitting ( Click on this link for more on cavitation ) When the bubble develops next to the overheated heating element, the bubble bursts and this energy will remove metal from the cooling unit tubing wall.

Thus, it should be conclusive to the casual observer that the Forbes article states that the Norcold Engineer stated that there is a corrosion problem along the welded joints. Therefore, it is just a fact that the Fridge Defend by ARP is necessary for controlling the boiler temperature so that this form of failure does not occur.
