Timer controlled drains

economical . . . reliable . . . available

The simple timer controlled drain is probably the most frequently installed as it's very reliable and has a low capital cost. STERLING’s selection includes 1/4″, 3/8″ and 1/2″ optimised 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 offer all drains with or without a ball valve & strainer according to customer choice, although we always recommend installing a strainer to protect the drain valve, as well as an isolating valve for easy removal when maintenance is 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.
