Our company is performing shutdown repairs to an ammonia refrigeration system which serves a commercial bakery. The photo shows a technician monitoring the flow meter of a tanker truck which is pumping anhydrous ammonia, R-717, into the system. R-717 is a natural refrigerant and has zero global warming potential, the lowest GWP of any refrigerant.
