UNIFLUX® Ammonia Heater Features

There are many applications of ammonia for industrial use. One of the most common uses of ammonia is as fertilizer for the agriculture industry. Ammonia heaters are used to heat pressurized cryogenic liquid from around -30°F to approximately +40°F. This allows for the ammonia to be stored in the pressurized liquid phase and loaded into tanker trucks for easier transport to the ultimate destination. The UNIFLUX® heater design is ideal for this application due to the ability to handle and control cyclic temperature fluctuations. The UNIFLUX ammonia heater is designed to handle condensing combustion products that are cooled by the cold process tube walls.
