Further investigation revealed unusual damage to the valve plug, indicating that an ammonia theft was likely attempted. Thankfully, circumstances must have cut the crime short, but the potential consequence of a such an occurrence are […]
Many refrigeration systems installed in California are equipped with a diffusion tank which is designed to receive and mitigate ammonia vapor that is released when a relief valve lifts. Since the common application of diffusion tanks has been limited to the west coast, our industry lacks best practices for sampling diffusion tank water for the […]

Many refrigeration professionals are not familiar with the 2017 ASME B&PV Code Section VIII Appendix M-11 recommendation that “Spring-loaded safety and safety relief valves normally should be installed in the upright position with the spindle vertical. Where space or piping configuration preclude such an […]
Hoses are commonly used to transfer chemicals from one container to another. Anhydrous ammonia is no exception. In non-refrigeration applications, it is important that facility owners familiarize with the requirements for pressure testing hoses. In California, OSHA requires that hoses be tested annually to twice the tank working pressure, but not less than 500 psi. […]
