1972 - Founded

Tempco Electric Heater Corporation was founded in August 1972 by Fermin Adames, Sr.

Established in Schiller Park, Illinois, Tempco began with three employees who manufactured and processed orders in a space of approximately 1500 square feet.

The first catalog totaled 24 pages with product details for three products – low-density cartridge heaters, hi-density cartridge heaters and mica-insulated band heaters.

2011 - Blizzard

The Groundhog's Day blizzard that hit Chicagoland in 2011 temporarily shut down Tempco for two days. Over a span of three days, upwards of 20 inches of snow fell and visibility was low. Along with high winds, there was thunder and lightning.

Snow had to be cleared away from the building because of how high it had drifted during the storm. Employees worked together diligently to make sure the building was safe to re-open.

We manufacture products used for medical devices, medical supplies, food service, transportation, additive manufacturing and energy.

Despite the many challenges of the pandemic, Tempco employees worked together to raise money to support the local Bensenville and Wood Dale Food Pantry.

Tempco was founded to manufacture electric heating elements for a wide range of industrial, commercial, scientific and medical applications. Mr. Adames’ leadership, ingenuity, dedication to hard work and focus on high-quality products and service have led Tempco to become one of the best electric heating element manufacturers in the world.

During the Company’s early years, Mr. Adames made a commitment to an ongoing program for the research and development of new and improved products. This foresight has contributed to the broadening of our product lines on a regular basis. As a result, Tempco has consistently met the needs of the diversified industries in which various types of heating elements are used.

Today we manufacture approximately thirty different types of electric heating elements and temperature sensors with hundreds of design variations. Some of our products were original developments in the industry for which Tempco holds patents. Many of our manufactured products are UL certified and CSA recognized. In addition to meeting our own rigorous quality standards, Tempco is an ISO:9001 certified company.

Over the years Tempco's growth has necessitated moves to larger facilities several times. Today we occupy our second and third custom-built offices and manufacturing facilities located in Wood Dale, Illinois. Our labor force consists of approximately 500 employees, and our annual sales are in the millions.

Tempco Buildings, Plant I and Plant IITempco is proud to produce American made and manufactured products.

We also service numerous industries where our products are used for heat processing.

In Memory of Our Founder – Fermin Adames Sr.

Fermin Adames Sr.Fermin was a man of many talents. He was an entrepreneur, engineer and mentor who spent a part of each day visiting every department at Tempco. But to really know who Fermin was and what was in his heart, one need to look no further than the three paintings he commissioned.

After the terrorist attacks on the United States that took place on September 11, 2001, he commissioned the first painting titled This Land is Your Land. In this painting, one or more landmarks from each of the fifty states and the District of Columbia are depicted. The Twin Towers of the World Trade Center are ghosted near the top in front of the American Flag.

The second painting, Nativity, depicts a Christmas scene in the small town of Nativity. Inspired by the desire to reduce the political correctness that has prompted many to replace the word 'Christmas' with 'Holiday' in recent years, Fermin commissioned this painting in 2005. He believed that people of every religion should be able to celebrate their important days without others changing their meaning.

The third painting, Defenders of Our Freedom, was commissioned to honor the men, women and animals (dogs and horses) who have served in the armed forces, winning and preserving our freedoms. Fermin was a veteran, and he felt a special respect for those who put everything on the line, including their lives, for all of us.


This Land Is Your Land

The first painting, This Land Is Your Land, became the back cover of our Visionary Solutions catalog from 2005 to 2011.           


Nativity became the cover of the Tempco Christmas Card for both 2006 and 2016.

Defending Our Freedom

The final painting, Defenders of Our Freedom, is on the back cover of our most recent catalog, the 40th Anniversary Edition.
