ENGINEERING DEPARTMENT

Engineering

We have three professional engineers on staff, available to provide an extensive array of services including assisting in compliance with PSM/RMP regulatory requirements and project engineering/design. Our engineers are constantly traveling to job sites for mechanical integrity checks and safety management.

Our History of Engineering


Doubl-Kold is proud to have an established engineering department since 1999. With multiple projects spanning farther than the United States to serve the industrial refrigeration industry.


Our engineers have assisted in dozens of designs for construction projects as well as remodeling and retrofitting. We strive to have the most efficient and user-friendly systems to give our customers the best opportunity to grow their company. Our engineers have the capability to visit our customers to physically assess and measure the systems for more precise support in our projects. 

Throughout the years, Doubl-Kold’s engineering department has hosted several Ammonia Emergency classes. In efforts to educate the community working with ammonia and ammonia emergency incidents, we provide annual refreshers on Ammonia Awareness and 24-hour Hazmat Technician courses. Courses provided by Doubl-Kold meet OSHA 29 CFR 1910.120 (q) requirements.


Having the opportunity to educate our community and fellow members in the industrial refrigeration industry allows us to expand our knowledge and understanding of the food packing and storage phenomenon. The laws and regulations within our industry are constantly being adjusted and added to so our engineers take the time to be part of the conversations and stay ahead of the fluctuating requirements.
