Condensate Drains

STELSEP offers a range of condensate drains, encompassing simple yet reliable timer operated devices, float drains and zero-loss drains that offer considerable compressed air energy savings.

Timer controlled condensate drains. The simple timer controlled drain is probably the most frequently installed type, because it is usually reliable and has a low capital cost. STELSEP’s selection includes 1/4″, 3/8″ and 1/2″ optimised as standard for condensate discharge, with adjustable ‘open’ and ‘interval’ periods. Open or discharge time is adjustable between 0.5 and 10 seconds, interval period is from 30 seconds to 45 minutes. We can supply all drains with or without a BVS (ball valve & strainer) according to customer choice, although we always recommend installing a strainer to protect the drain valve and an isolating valve so that it can be easily removed for maintenance if required. We offer multiple voltage choices and because we’ve been working with these drains for some years we know for certain that they are at least as reliable and economical as you can get.

Electronic ‘zero-loss’ drains. Because the quantity of condensate that needs to be drained varies by the hour, the day and the season there is an inevitable loss of compressed air when using a drain with a fixed open/close profile. Zero loss drains collect condensate, monitor the level and expel it under system pressure – either for a predetermined period or until the level has reduced by a preset amount.

The monitoring is normally done by a capacitive sensor (or two if the drain senses the lower level). Installation has to be carefully considered as the plumbing can affect operation, but properly installed and maintained these drains can save hundreds of dollars per year compared with a timed drain.

STELSEP’s carefully chosen selection of zero loss drains incorporates the best of currently available technologies with options for both local and remote alarms, built-in and easily serviceable strainers, and flexible installation options
