Dometic cooling units are designed to be durable and reliable. norcold cooling units They are manufactured from high quality carbon steel with a copper core and an insulator layer, and a heat exchanger. This provides a more efficient cooling system. It also reduces refrigerant charge, which is an important factor in reducing power consumption and fuel use.
There are two production facilities in Europe for Dometic absorption refrigeration products, one in Siegen (Germany) and the other in Jaszbereny (Hungary). Both plants currently use sodium chromate as corrosion inhibitor of the carbon steel cooling system.
Using sodium chromate is a safe and effective way to protect against corrosion in a cooling system with a copper core. Sodium chromate is available in the EU and can be purchased from authorized dealers.
A number of studies have been conducted in order to evaluate the environmental impact and human health risk of sodium chromate on air, water, soil and food. These studies have shown that sodium chromate is safe to use and does not pose any risks to humans or the environment.
However, Dometic is currently evaluating alternatives to sodium chromate as the corrosion inhibitor in its absorption refrigeration systems. These alternatives include the development of a new corrosion inhibitor, which is based on a different compound. This inhibitor, called inhibitor 7, has been tested in field trials and will be introduced to the market when it has been proven to function properly.
Dometic will first use inhibitor 7 to protect its products with low boiler temperatures, then progressively introduce these products with higher boiler temperatures to the market. The new inhibitor will be incorporated into the design and manufacturing process of these products.
The transition to the new alternative inhibitor can take up to 12 years and will involve reengineering of all Dometic products in its European production sites, and a significant redesign of the cooling unit and assembly line. The total cost to replace the existing product portfolio with a new one is estimated to be 36,307,447 EUR.
In addition to the economic costs of the non-use scenario, there are social impacts as well. The local business communities, which rely on subcontracting from Dometic, may lose contracts and jobs as a result of the non-use scenario. The adjustment of the product mix, which would reduce the range of products offered by Dometic, could lead to discontinuation of some product lines, which in turn reduces Dometic’s competitiveness.
These changes to the product portfolio would have an impact on Dometic’s market share, and this in turn could have a negative effect on Dometic’s financial position. The reduced range of products and increased cost to deliver legacy parts are likely to increase the replacement cost for end customers.
For customers who want to continue to use the existing sodium chromate containing products in their RVs, the company can offer them alternatives that are less expensive and have no adverse effects on the environment or human health. For example, a new Dometic CoolAir truck air conditioner uses a fraction of the energy that a conventional cooler consumes to cool down the vehicle, while being much more efficient and cost-effective.
