Condensate is something that is always present in a compressed air system, but it’s also a byproduct that needs to be removed. If it’s not eliminated, you should expect awful consequences: downtime, adverse product quality and efficiency, or even issues downstream in your air tools.

There are many drain options out there – manual drains, float drains or solenoid operated drains – but the benefits of choosing a zero air loss condensate drain are hard to dispute.

What is a zero loss condensate drain?

Zero loss drains reliably remove unwanted water, chemicals, or other moisture in the air from your compressed air system. And they do so while providing maximum energy savings. Zero loss drains only open when liquid is present and do not allow any compressed air to escape from the system – compressed air costs money, hence the savings.

Why do you need a zero loss condensate drain?

All compressed air systems have condensate present, and you need to get rid of it. If the condensate is not removed from the compressed air system, your product quality can be impacted, as will the efficiency of your production. It may even lead to downtime or issues with your downstream tools.

The removal of condensate is especially important in industries such as in the pharmaceutical field, which need to get rid of moisture prior to packaging medications.

What are the advantages to choosing a zero loss condensate drain?

A zero loss drain means you won’t lose any of your air pressure while getting rid of moisture. Compare this to a manual drain. On manual drains, operators are required to manually open the valves to discharge condensate. This requires constant attention and leads to excess air loss, because the air escapes when the valve is left open to drain the condensate. Lost compressed air is lost money! In addition, as the pressure blows out, you lose pressure and must build that pressure back up – meaning your compressor must work harder than it really needs to.

By choosing a zero loss condensate drain, it automatically drains the condensate. In addition, when a minimum level of condensate is reached, the valve closes before compressed air can escape.

What kind of savings can I realize?

Some customers shy away from zero loss drains because of a higher upfront cost. However, they often don’t realize that the payback is typically within 6 – 12 months at most.

Ultimately, your savings would depend on the cost to run the machine, how much air you’re losing and the number of drain valves in your facility. Look at our estimated annual cost of use of different drain types. The major takeaway? A zero loss drain or one of Sullair SULLIMAXTM condensate drains is the way to go on the long run.

Zero loss drains are the top choice for reliably removing condensate and preventing the loss and waste of compressed air. Compressed air is one of the most expensive sources of energy in a plant, so who wouldn’t want to reduce the amount of lost air?
