	Nathan Kramer, a metalsmith from Russia, established Kramer in 1914 in Trenton, New Jersey, with automobile radiators as the company’s first product. Staying with finned coils and heat transfer, the company expanded into building refrigeration equipment, establishing a working relationship with Hill Refrigeration, also located in Trenton. Over the years, Kramer earned a reputation for quality, long-lived products while also leading the refrigeration industry with innovation and new product development. Kramer was the originator of packaged condensing units, engineered systems that matched compressors to coils for optimum performance and reliability. To expand, the Kramer family established additional manufacturing plants, with each business named by its location, Kramer-Trenton, Kramer-Pittsburgh, Kramer-New York. During World War II, Kramer’s product lines shifted temporarily from refrigeration equipment to artillery shells. During this time the company closed its Pittsburgh and New York plants and the company became identified as Kramer-Trenton. Nathan Kramer remained the driving force behind the company until his death in 1959 when Israel Kramer became president. One of Kramer’s over thirty patents is on the exclusive Minimum Charge Monitor®, which permits fully charging a system simply and quickly with a minimum of refrigerant. The Kramer-developed Thermolator™ used in Kramer-Saver® split systems helps keep energy costs low refrigeration systems on the market. In January 1990, Kramer-Trenton Co. closed its doors and the rights to the products and designs and name were acquired by Ardco Inc. Today, the Kramer philosophy of quality and innovation continue, with tens of thousands of reliable systems and products still operating and supported in the field, and new refrigeration equipment achievements being realized. New medium profile evaporators were introduced in 1995. Further refinements on the famed Thermobank® design were patented in 1997. After 82 years, Kramer-Trenton continues to lead with achievements in heat transfer, as it did when Nathan Kramer first started the business. It remains as true today as in 1914 that quality is the best investment.
