Ammonia is a potentially dangerous chemical requiring either high-pressure storage vessels or low temperature refrigerated vessels. Safe storage of large volumes of ammonia can be accomplished using properly manufactured vessels built to strict code compliance. Little P.Eng. Engineering is a leading ammonia tank manufacturer. We provide custom fabrication of ammonia storage tanks that conform to customer-supplied specifications. Located in Calgary, Alberta; Vancouver, BC; Toronto, Ontario; Buena Park, California; We serve our clients across Canada, USA and Middle East.

Sizing Anhydrous Ammonia Storage Tanks
We manufacture ammonia tanks keeping in mind, the different physical states, and behavior of ammonia gas,. Ammonia tank fabrication is performed to ensure maximum safety and reliability. The following factors are taken into consideration when manufacturing standard or custom ammonia tanks:
At 60°F, anhydrous ammonia liquid weighs approximately 5 pounds per gallon.
5 SCF of ammonia vapor and 45 SCR of dissociated ammonia gas is generated by a pound of liquid anhydrous ammonia.
A storage tank is designed keeping in mind that only 85% of its volume can be utilized. (Since the gas expands, vapor space of 15% is maintained to ensure safe storage and operations.)
