About Us

California Controlled Atmosphere (CalCA) is a California industrial refrigeration company dedicated to providing our clients with a one-stop resource for all of their industrial refrigeration needs.

Over the past 30 years, we have grown from a small family business to an employee-owned corporation that is widely recognized as Central California’s leader in industrial refrigeration services.

We specialize in mechanical systems design, installation and maintenance for product cooling and cold storage/freezer facilities. In order to help our clients navigate the complicated maze of government regulations, we also offer consulting services through our sister company Resource Compliance, Inc. to help our clients comply with Risk Management Program (RMP) and Process Safety Management (PSM) regulations. Our controls department also provides the most advanced automated control and energy management systems using a wide variety of control platforms.

Why CalCa?

We will do for you what others will not—or simply can not. We have thrived as a company because we are willing and able to help our clients solve complicated problems that other California industrial refrigeration services usually shy away from.

Unlike many California industrial refrigeration contractors, we stand behind our work. In fact, we stake our reputation on it. Our job is not finished until you are satisfied. Period. This approach has led to many long-term relationships with our customers and accreditation by the Better Business Bureau of Central California.

In the ever-changing landscape of government codes and regulations, we have made it a priority to keep our customers ahead of the curve with compliance issues, partnering with Resource Compliance  Inc. to provide comprehensive Risk & Process Safety Management solutions.

Remembering Ray

In 1984, Ray Kliewer took a leap of faith and started CalCA out of his garage on a small five-acre raisin farm in Dinuba. Persevering through the many challenges of starting a new business, Ray grew the company thanks to his dedication to quality, honesty, and plain old hard work. Today, CalCA is an employee-owned corporation servicing clients throughout California and as far as India and China.

Ray passed away on July 11, 2009. At CalCA, we honor him every day by carrying on the tradition of teamwork, strength, and experience that the company was founded on.
