History of the original inline gas heater.

1938

In 1938, Roy E. Mcllrath managed soda fountain operations at the Aragon Ballroom in Chicago. He was constantly facing carbon dioxide freeze-ups when gas flows increased.

Roy invents and patents the “automatic electric carbon dioxide heater”—the forerunner of today’s model. He later sells the company to Calco owner, [Name], from whom he was leasing space.

1980

In 1980, Calco contracts Modern Engineering to begin manufacturing heaters.

1993

In 1993, Calco creates the first custom heater for IBM to heat nitrogen up to 400°F with a special 300-watt, 220-volt, adjustable temperature control model with stainless steel tubes—the birth of the second heater, Model CC-1000.

Today

Today, Calco is still the world leader in quality, inline heaters to prevent gas flow freeze-ups.
