Systems for pressure separation in tunnelling and mining

Hydraulic pressure separation of water circuits

Because of great depths in mining and tunnelling it is often necessary to make a hydraulic pressure separation of water circuits.

For that application WAT offers a special system for pressure separation, e.g. between the central refrigeration system on surface and the air-cooling at underground. A battery of shell & tube heat exchangers from our in-house production is used here.

WAT HP/LP – heat exchangers are especially designed for aggressive water fluids in primary and secondary water circuits.
