KOOLTRONIC 70TH ANNIVERSARY
From its early New Jersey roots to today’s Pennington campus, Kooltronic has spent 70 years advancing products, manufacturing, people, and innovative thermal management solutions.
THE STORY OF
PROGRESSION
The experience now begins with the original building and today’s campus, then continues through the major advances that changed Kooltronic: facility growth, product evolution, testing improvements, and the enduring strength of American manufacturing.
CHAPTER 01 / OUR HERITAGE
Four archival-reference views of Kooltronic’s buildings—from the original Princeton beginnings to the modern Pennington campus.

An original architectural illustration records Kooltronic’s early Princeton facility and its beginnings in 1956.
THE KOOLTRONIC EVOLUTION · 1956–2026
New technology. New capabilities. New standards. Follow the documented milestones that transformed a small New Jersey manufacturer into a specialist in industrial thermal management.
Kooltronic begins by making fans and blowers for the emerging electronics industry.

A focused beginning in air movement establishes the company's manufacturing and engineering roots.
Heat exchangers and closed-loop enclosure air conditioning broaden the company's offerings. Company history identifies its first closed-loop enclosure air conditioner in 1967.

Protection of heat-sensitive electronics becomes a defining area of expertise.
Operations move to a 100,000-square-foot Hopewell facility in 1975. A 1984 expansion adds 22,000 square feet and an automated powder-paint system.

Larger capacity and an upgraded finishing process support more sophisticated manufacturing.
This 2002 construction-stage building photo represents the company’s middle chapter—an important step between the earlier historic facility and the newer modern-era operation that followed.

It makes the progression tangible: Kooltronic was not only growing products and capabilities, but also evolving its physical environment on the way to today’s operation.
Solar installations begin in 2006 and expand in 2011; patented hazardous-location air conditioners arrive in 2015; advanced in-process testing is implemented in 2020; the slim Access Series launches in 2021.

Broader capabilities and greater process control strengthen the company's technical platform.
These present-day factory images show where Kooltronic stands today: active manufacturing, technical environments, and a company still developing enclosure cooling and airflow solutions in New Jersey.

The journey now lands in a real current-day setting, showing how the historic foundation, the transition years, and modern operations connect into one continuous story.
