Condensate drain ZLD series

automaticfloatzero-loss

Finite's zero loss condensate drains are desinged for economical removal of unwanted water, oil, emulsions, and other liquids. These drains will only open when liquid is present and will not allow compressed air to escape from the system. Advantages of Finite's ZLD: • Automatically drains condensate • When minimum level of condensate is reached, the valve closes in time before compressed air can escape • Includes an integrated dirt screen between the level measurement and drain valve to protect the diaphragm valve • Drain will remove condensate when liquid reached the high level sensor • The drain will not operate until the liquid level reaches the high level sensor • Particulate contamination is removed by the integrated dirt screen before fouling the outlet port Disadvantages of ther types of Drains: • Requires constant attention • Always leads to excess air loss because air escapes when the valve is left open to drain the condensate • Float is susceptible to blockage from particulate contamination in condensate • Often sticks in open (leaks excess air) or closed position (no condensate is drained) • The period for which the valve is open might not be long enough for adequate drainage of accumulated condensate • The valve will operate even if little or no condensate is present, resulting in air loss • Often requires a strainer to remove particulate contamination which can block the inlet and outlet ports How do they work? There are two collection tanks inside the ZLD housing. Tank one contains an electronic level controller that continuously monitors the liquid level inside the drain. Tank one stores condensate until it is drained away.
