MINE COOLING
The SIEMAG TECBERG group is a world leader in the application of the “Three Chamber Pipe Feeder” technology to mine cooling and desalination systems. Many mine-cooling systems rely on turbines for the recovery of energy from descending chilled water, however this is an inefficient solution and with today’s heightened awareness of ecological considerations and energy constraints, a new solution is required.
The three-chamber pipe feeder or pressure exchange system (P.E.S.) is a system for use in underground cooling systems. Situated below ground, the P.E.S. forms the link between two circuits, being a high-pressure circuit and a low-pressure circuit.
Winder Controls offers design, manufacture, installation, commissioning and maintenance of pressure exchange systems for new mine designs as well as for the conversion of existing turbine systems.
RECONDITIONING, REFURBISHMENTS AND UPGRADES
Winder Controls has extensive experience in the upgrading and refurbishment of all types of winders and related equipment.
We have carried out a significant number of large refurbishment projects, ranging from the replacement of worn components, to the total replacement of rotating masses to suit existing foundations and drive systems.
