冷凝水处理

A 30 kW machine in a humid climate can produce over a hundred litres a day. It has to go somewhere, and in most plants nobody has decided where.

Not from a lubricated compressor. That liquid contains oil and discharging it is illegal in every market we operate in: an oil-water separator brings it below 10 ppm first.

It opens whether there is water there or not, and every time it opens with no water it blows away compressed air. Timer drains typically waste 2–4% of a plant's total output.

It senses the liquid level and opens only when there is water to remove. No air escapes, which is why it pays for itself quickly on any machine above about 15 kW.

One or two filter cartridge changes a year. That is far cheaper than tankering condensate away, which is the alternative on sites that take the rules seriously.

Water reaching the ring main is the late symptom. Fit drains with a volt-free fault contact and you find out before the water does any damage.

At the aftercooler, the receiver, the dryer and every low point in the pipework. A single drain at the compressor is not enough for a distributed system.

It needs drains, but not an oil-water separator. The condensate is clean water, so there is nothing to separate and nothing to declare.

Yes, and they are the item most often forgotten. A blocked drain is the single most common cause of water downstream, and clearing one takes minutes.

Discharge limits differ by country but all of Pakistan, the UAE, Saudi Arabia, Oman and Türkiye restrict oil in effluent. We specify to the limit that applies where the machine is installed.
