The separated steam is vented to atmosphere or returned to the deaerator. The liquid portion is then passed through an atemporation which mixes cold water with the blowdown to reduce the temperature to acceptable levels for discharge to drain.

A16DS – Simplified Automatic Aftercooler. Similar to our 18DF aftercooler described above only without the middle flanges. This aftercooler accommodates the cold water line, sensing bulb, and thermometer. Sizing should match the drain line size. Cooling water selection from Chart “B: assures adequate cooling of condensate to drain. Self Actuating Temperature Regulator Valve Automatically controls the flow of cooling water to the aftercooler fittings by responding to the temperature change at the bulb. Each is factory set at 135 deg. F. with an adjustable range from 115- 180 deg. F. the 6’ capillary allows installation of the valve in the cold water line while the bulb is remotely located in the aftercooler. The valve size should correspond to the recommended size on Chart “B” “Y” Type Strainer Cast iron construction with a .033 inch stainless steel screen are recommended prior to temperature regulator valve or solenoid valve in the cold water line to protect these cold water valves. Bi-Metal Thermometer Stainless steel body in 4” or 6” stainless steel stem. ¼” connection provided for use in the A18DF, A16DS or A20AO aftercoolers. Graduated scale shows temperature range 50 to 300 deg. F.
