By maintaining proper room sanitation, you will reduce contamination from fungi, bacteria, and mold that can lead to spoilage. This not only improves fruit quality but also enhances the efficiency of your CA equipment system. Debris, dust, and microbial buildup can interfere with sensors and airflow systems. Keeping the room clean allows for more precise control of oxygen, humidity, and carbon dioxide levels. Overall, room sanitation improves product quality and helps achieve better results.

Pressure testing a cold storage facility increases airtightness, improving control over internal gas conditions. Identifying and eliminating leaks enables the room to maintain lower oxygen levels more efficiently, reducing energy use for your scrubber and nitrogen systems. Enhanced sealing also enables more precise regulation of carbon dioxide concentration, which is essential for controlled atmosphere storage.
As a result, facilities can achieve and maintain target atmosphere conditons even if the nitrogen system has limited capacity or is not installed. overall, pressure testing enables more effecient operations, improved product preservation, and less reliance on supplemental gas systems.

You want your operation, whether it is freezing, cold storage, packaging, or other automated process, to be accurately monitored and controlled. Our goal is to provide you with peace of mind, ensuring that your products are protected and that your paperwork is in order at every step of the process. We are USDA certified to perform temperature probe calibration. We are familiar with Empire Control Systems and DK systems.


Ammonia is a toxic gas and the proper safety monitoring procedures and equipment must always be in place to avoid serious accidental injury or death. We provide Oxygen and ammonia detection services; installation, calibration, and maintenance to meet standards for safety in refrigeration, chemical processing, and food industries.
Ammonia detection systems can counteract the possible effects of leaks, preventing equipment or property damage, personal injury, and loss of life.
