Servel, Inc. (Gas-Powered Refrigerators)
A Wartime Message
March 23, 1942 Life Article

March 23, 1942 Life

March 23, 1942 Life Cover - RF Cafe[Table of Contents]

Wax nostalgic about and learn from the history of early technology. See articles from Life magazine, published 1883-1972. All copyrights hereby acknowledged.

Servel is not a name that immediately comes to mind (and probably not at all) when thinking of companies who manufactured refrigerators or any other household appliances. However, they were rather prominent in the in the early 1940's when this "Wartime Message" appeared in a 1942 issue of Life magazine. So, too, was Crosley, a name which lives on today, and they still make refrigerators (at one time manufactured by Westinghouse). Unique about Servel refrigerators was that they operated off of natural gas. It might seem strange that a cooling - even freezing - process can be accomplished via a flame, but such is the case. In fact, Melanie's parents had a gas-powered refrigerator and a gas-powered chest freezer at their house on a mountaintop in West Virginia, where they got free natural gas from a well a gas company operated from their property. But I digress... The motivation for posting this piece is that Servel was one of hundreds of American companies that spent some of their hard-earned their advertising money to promote the sacrificial efforts of fellow citizens (many of whom were former employees or relatives of current employees). It was a time when major companies were owned and run entirely by patriotic Americans.

Servel Company: A Brief Overview and Historical Context

Colonel William McCurdy Jr. was a businessman and the founder of the National Electric Products Company, which later became known as the Servel Corporation. The company was known for producing a variety of electrical appliances, including refrigerators.

The Servel refrigerator was one of the company's most successful products, and it was known for its innovative use of natural gas as a coolant. This allowed the refrigerator to operate without electricity, making it popular in areas where electrical service was not yet available.

The slogan "Serving Electricity" was used by Servel as a way to promote its products and highlight the company's commitment to providing reliable and efficient electrical appliances. It was a clever play on words, as the Servel refrigerator was actually powered by natural gas, not electricity.

Today, the Servel Corporation is part of the Dometic Group, a global manufacturer of a wide range of products for the RV, marine, and hospitality industries. However, the Servel refrigerator continues to be remembered as an important innovation in the history of electrical appliances.

A Wartime Message to the 2,000,000 owners of Servel Gas Refrigerators

On April 30th, the last refrigerator for normal civilian use will have rolled off the lines at Servel - and at every other refrigerator plant in America.

From that day - and until victory is won - every resource and facility of this industry not already devoted to war production will be geared to all-out manufacture of these vital materials.

Because automatic refrigerators have come to play such an important part in the lives of most families, it is natural that this change-over may raise some questions in people's minds. "Will my present one last?" "Suppose it doesn't?" "Can I still get service?"

You, as a Servel owner, are familiar with the qualities of the Gas Refrigerator. You remember your reasons for buying it. You can be assured, therefore, of this:

Your refrigerator is not likely to need repairs.

There are no moving parts in its freezing system. No moving parts means nothing to wear or cause noise. It means long life.

Besides, the order stopping the manufacture of refrigerators will not reduce or impair facilities for inspection and service. Servel will continue to cooperate with Gas Utilities, Distributors and Dealers in servicing Servel Refrigerators. You can feel confident that your refrigerator will continue to operate - will continue to provide you and your family with safe food protection and ice cubes.

Today, Gas Companies are also serving you another way. Their home economists are working hand-in-glove with the government on the National Nutrition Program. They'll show you how to feed your family better and more economically. Give you latest information on foods that keep you fit.

Looking beyond today, no one can say for sure what refrigerators are going to be like when peace returns. No one knows. But this is certain - that there will be refrigerators - that we'll be making them (and who knows what other modern appliances!) - and that they'll be finer than ever.

Gas-Powered Refrigerator

A gas-powered refrigerator, also known as an absorption refrigerator, works on the principle of using heat to drive a cooling cycle. The basic components of a gas-powered refrigerator are a heat source, a refrigerant, and an absorber.

The heat source is usually a propane flame or an electric heating element. The heat from the source is used to boil a refrigerant, typically ammonia, which turns into a gas and rises to the top of the system.

The refrigerant gas then enters the condenser, which is located outside the refrigerator and dissipates the heat, causing the refrigerant to condense back into a liquid.

The liquid refrigerant then flows into an evaporator inside the refrigerator, where it absorbs heat from the interior, causing it to evaporate back into a gas.

The refrigerant gas then flows into an absorber, which contains a solution of water and another chemical, usually lithium bromide. The refrigerant is absorbed into the solution, which generates heat that is removed through a radiator or cooling tower.

Once the refrigerant is absorbed, the cycle starts again. The gas-powered refrigerator operates continuously as long as there is heat applied to the system.

Gas-powered refrigerators are often used in recreational vehicles, cabins, and other off-grid locations where there is no access to electricity. They are also used in some industrial and commercial applications.

Crosley Refrigerators: A Brief Overview and Historical Context

Powel Crosley Jr.'s impact on American consumer culture extended far beyond his revolutionary work in radio and broadcasting. In the 1930s, he turned his inventive genius toward household appliances, most notably refrigerators. His introduction of the Crosley Shelvador refrigerator would change the way Americans stored food and positioned Crosley as a key player in the appliance industry. The evolution of Crosley refrigerators was characterized by innovation, affordability, and a strong understanding of consumer needs, and the Shelvador's success was an example of how Crosley transformed everyday household products into essential conveniences for American families.

The 1920s and 1930s were a period of significant innovation in the home appliance market, driven by increasing electrification and the rise of modern kitchen technologies. Early refrigerators were a luxury, out of reach for many American households due to their high price. The first electric refrigerators, introduced in the 1910s and 1920s, were cumbersome, expensive, and not yet optimized for mass production. Crosley, recognizing the potential of this new technology, sought to revolutionize the refrigerator industry just as he had done with radios - by making them more affordable and user-friendly.

In 1934, Crosley introduced what would become his most famous contribution to the refrigeration market: the Shelvador. This refrigerator was a groundbreaking innovation that changed the way refrigerators were designed. The defining feature of the Shelvador was its shelves built into the inside of the door—a concept so obvious in retrospect, yet no one had thought of it before. This innovation dramatically increased the usable storage space within the refrigerator without requiring a larger exterior footprint. By utilizing the often-overlooked space in the door, Crosley allowed consumers to store bottles, jars, and smaller items more conveniently, freeing up shelf space inside the main compartment for larger goods.

The Shelvador's design made it an immediate hit with consumers. Families appreciated the increased storage capacity, which allowed them to organize their food more efficiently and keep perishables fresher for longer. The convenience of having commonly used items, such as milk bottles or condiments, easily accessible in the door was a major selling point. Crosley was also careful to price the Shelvador competitively, ensuring that it was within reach of the growing middle class during a period of economic recovery after the Great Depression.

Crosley didn't stop at merely improving the design of the refrigerator—he also introduced several innovations in terms of materials and construction. The early Shelvadors were built using durable steel and were insulated with cork, a common material at the time for refrigeration insulation. The steel cabinets were sturdy and designed to last, and Crosley paid close attention to the quality of the finishes. These refrigerators were often coated with enamel finishes, which made them easy to clean and resistant to rust and stains. As the 1930s progressed, Crosley improved the insulation materials, eventually transitioning to more modern materials like fiberglass to improve efficiency and reduce energy consumption.

Throughout the 1930s and 1940s, Crosley continued to refine his refrigerators, making them more energy-efficient and reliable. Early refrigerators, including the Shelvador, often had separate compressors that could be quite noisy, but Crosley's engineers worked to improve these components, reducing the noise level and improving the longevity of the refrigeration units. As electricity became more widely available across the United States, particularly in rural areas, Crosley focused on making his appliances suitable for a wide range of environments. Some models were designed to operate efficiently even in areas with inconsistent electrical supply.

One of Crosley's key strategies in the refrigeration market was his focus on affordability. He used the same mass-production techniques that had made his radios so successful, driving down costs and passing the savings on to consumers. This approach was particularly important during the late 1930s and early 1940s, when America was still recovering from the Great Depression and many families were cautious about large expenditures. Crosley's refrigerators offered a combination of cutting-edge technology and budget-friendly pricing, making them an appealing option for cost-conscious consumers.

In terms of advertising, Crosley applied the same savvy strategies that had worked so well for his radios. He positioned the Shelvador as a must-have appliance that made everyday life easier. Ads often emphasized the unique door shelving system, highlighting how much more food it could hold compared to traditional refrigerators. Crosley's marketing also stressed the refrigerator's reliability and durability, which reassured consumers that they were making a long-term investment. As with his radios, Crosley's extensive use of print media, radio commercials, and demonstrations in department stores helped solidify the Shelvador's place in American kitchens.

The Shelvador's success helped Crosley become a major player in the appliance industry. By the late 1930s, Crosley refrigerators were sold across the country in department stores and appliance dealerships. The company had a nationwide network of distributors, which ensured that Crosley products were accessible to a broad market. Crosley also expanded his product line, offering different sizes and models of refrigerators to suit various customer needs—from small units for apartment dwellers to larger models for families.

As World War II began, Crosley shifted his company's focus to support the war effort, much like other American manufacturers. The production of consumer goods, including refrigerators, was curtailed as factories were repurposed for the manufacture of military equipment. Crosley Corporation, in particular, was involved in producing radio and communication equipment for the U.S. military. Despite the temporary halt in appliance production, Crosley refrigerators remained popular, and many households continued to use their pre-war models well into the post-war era.

After the war, the post-World War II economic boom created a surge in demand for modern appliances. Crosley was quick to capitalize on this trend, resuming production of the Shelvador and introducing new models with additional features and improvements. Post-war Crosley refrigerators were even more advanced, offering better cooling technologies, more efficient compressors, and larger storage capacities. The company also began experimenting with different designs and finishes, such as chrome accents and pastel colors, which reflected the aesthetic trends of the 1950s. These models were aimed at the rapidly expanding suburban market, where modern kitchens became a symbol of the American dream.

Crosley also responded to growing consumer demands for freezers, introducing combination refrigerator-freezer units that allowed households to store frozen foods for longer periods. The convenience of having both fresh and frozen food storage in one unit made these appliances particularly appealing to post-war families, who were enjoying the benefits of increased prosperity and larger homes with spacious kitchens.

Despite these advances, Crosley faced increasing competition from larger and more established companies like General Electric and Westinghouse in the post-war period. While the Shelvador had been a revolutionary product, the refrigeration market had become more crowded, with other manufacturers adopting similar designs and improving on them. By the early 1950s, Crosley's share of the market began to decline, and the company faced financial challenges. The rise of these competitors, combined with increased production costs and changes in consumer preferences, eventually forced Crosley out of the appliance business. In 1956, Crosley's appliance division was sold to AVCO Manufacturing Corporation, marking the end of Crosley's direct involvement in the refrigerator market.

While Crosley's time in the appliance industry was relatively brief compared to his success in radio, the impact of the Shelvador was long-lasting. The concept of door shelving became standard in refrigerator design, and many of the innovations introduced by Crosley, such as efficient storage solutions and user-friendly designs, became benchmarks for the industry. Crosley's emphasis on affordability also helped democratize access to modern refrigeration, making it possible for millions of American families to enjoy the convenience of a refrigerator in their homes.

Powel Crosley Jr.'s contributions to the appliance industry reflect his broader philosophy of making life easier and more comfortable for the average American. Just as he had done with radios, Crosley revolutionized the refrigerator by introducing innovative, practical features and making them affordable to a wide audience. Although his appliance business did not last as long as his radio empire, the Shelvador remains a symbol of his forward-thinking approach to design and his understanding of consumer needs. Crosley's influence can still be seen in modern refrigerators, where efficiency, convenience, and thoughtful design continue to be key factors in their success.
