When Mr. H.O. Trerice founded our company back in 1923, America was a different place. We were a nation of industry. A country whose landscape was dotted with steel mills, foundries and factories. The entrepreneurial spirit of the twenties was in full swing, giving rise to a variety of new and exciting businesses. And the fledgling American automotive industry was just getting ready to take off on a fabulous joyride.
In this bustling and excitement-charged environment, Mr. Trerice saw both a need and an opportunity. The very backbone of America’s industrial growth, the boiler rooms and powerhouses of her factories and foundries, needed a reliable source of accurate, durable instrumentation and controls. He was determined to become that source.
And so, the H.O. Trerice Co. was born: designing, engineering and manufacturing the reliable, high quality, steam, boiler and HVAC instrumentation and controls early industrial America would use to power her way into the future.
Today, the H.O. Trerice Co. provides a full spectrum of the finest quality temperature and pressure instrumentation and controls demanded by industries the world over. Our marketplace literally is the world, and we are serving our customers every day all over the globe.
Wherever used, Trerice instrumentation and controls are considered the standard for quality and dependability. Chemical plants, food processing, petroleum refining, pharmaceutical manufacturing, the list of industries that rely on Trerice goes on and on.
