In a typical compressed air system timer-based drains are installed at multiple locations such as at the bottom of air receivers, filters and even dryers. The timer drain has a fixed interval after which the solenoid in the drain opens the valve and releases the condensate trapped inside it. However, sometimes there is no condensate trapped inside the drain. In this situation, when the drain opens only air is leaked out. This is similar to having someone purging the extremely valuable compressed air to the environment. This sort of “man-made” leakage causes a lot of energy wastage, not to mention the tremendous financial implications of this wastage.
All compressed air audits focus on the leakages in the line but conveniently ignore this massive leakage occurring in the line at regular intervals. It is important to not only eliminate this leakage entirely from the system but to also have a fool-proof system for condensate drainage.
This is where Parker Domnick Hunter’s Zero-loss Condensate Drains can help you. There are two types of zero-loss drains namely, mechanical and electronic. Both are explained in detail below.
Zero-loss Mechanical Condensate Drains
| In this type of drain, there is mechanical float-ball type arrangement in the drain. When the float ball rises up to a pre-determined height, due to the filling of condensate inside it, the valve opens releasing the trapped condensate. When the float ball drops to a certain level the valve closes, trapping whatever condensate is left inside it but making sure that no compressed air is leaked out at the time of valve opening. This drain requires zero maintenance and does not require any electrical connections. |  |

Zero-loss Electronic Condensate Drains
| In this type of drain, there is an electronic sensor which detects the level of condensate trapped inside the drain. When the level reaches a certain set point the valve is opened electronically. However, there is also a minimum level at which the valve is closed. This ensures that no air lost at the time of the opening of the valve. This drain, as the name suggests, requires an electrical connection for it to operate. |  |
