Air is one of the essential needs that used by living things either directly or indirectly. The demand for nitrogen in the chemical industry in the world continues to increase every year, especially in the fertilizer industry. In the industry, nitrogen can be used to manufacture ammonia or start tipping on an ammonia plant, also to protect materials from bacterial and fungal disorders. In addition, in the field of nitrogen transport is often to add to vehicle restrictions Pump the wheels using nitrogen will make the wheels more durable and the wheel rim is not easily damaged. Based on the amount of demand for nitrogen gas, the nitrogen production process is conducted by Pressure Swing Adsorption (PSA) method. The adsorption capacity of the adsorbent depends on the temperature, pressure, type of adsorbent and characteristic of the adsorbent. In this case, the temperature at the process is one of the most important parameters, the temperature, in this case, is the temperature of the adsorbate. When a gas or adsorbate molecule is attached to the surface of the adsorbent, there will be an energy release called an exothermic event. The reduced temperature will increase the amount of adsorbate adsorbed and also for the opposite event. Because of that, it is needed an air conditioner in the form of a cooler that serves to maintain and reduce the air temperature of the feed (adsorbate) does not experience an increase when operating conditions take place. The highest nitrogen purity was 95.7%, at 7 bar PSA, cooling fluid flow rate 35.4 m/s, daily cooling 41.58%, and air feed temperature 30.7°C.
