The aNH3 SuperCool heat exchanger was designed to do what others cannot. The typical “shell and tube-style” heat exchanger produced by some companies in the industry have been used for decades and haven’t really changed much. When the gas/liquid mixture arrives at the heat exchanger, it has to be condensed back into liquid form thus allowing the Flowmeter to count the liquid accurately. The amount of usable liquid that can be obtained from a heat exchanger depends on two very important factors: The amount of coolant used, and the surface area (square inch) allowing the mixture to be brought back to liquid form.
The amount of liquid used for cooling can vary among manufacturers, depending on tank temperatures and rates, some vapor lines can reach anywhere from 150 - 200 gallons per hour of liquid NH3. In most cases being applied to an individual row that is already getting the correct amount of N. That amount of NH3 can add up in a hurry and starve other rows of the correct amount. The practice of dividing vapor lines among rows helps to an extent, but is still an excessive amount of unneeded NH3.
The cooling surface among heat exchangers is important to help determine flow. Typically the more cooling surface a heat exchanger has, the more product can be passed through it. Most heat exchangers in the industry today are anywhere from 200 – 900 square inches of cooling surface.
What We Do Differently
The aNH3 heat exchanger is very simple yet heavy-duty. It is a one-piece all stainless-steel design. The operator no longer needs to worry about corrosion and faulty O-rings. Our design is very durable and made to hold up to harsh conditions. A large basket style filter attached to the inlet side of the heat exchanger for easy cleaning.
The cooling capacity of this product simply supersedes anything on the market today. The surface area for coolant capacity is over 11,000 square inches, over 10x larger than anything in the industry. Our concept for cooling is very unique, instead of using a very large steady stream of NH3, We use a very small stream. Not only does this allow for better cooling, but minimizes the amount of vaporized NH3. No longer is there a need to split vapor rows among knives to help cut down on excessive NH3 vapor. The aNH3 system is designed to be highly accurate, by minimizing the amount of coolant by nearly 90% from other manufacturers in the industry.
