KTI Underground Chiller (UC)

The KTI Underground Chiller (UC) is a mobile weather cooling machine specifically designed for underground mining applications. Both evaporator and condenser are designed to operate with heavily polluted and contaminated water and outperform conventional components in this application.

Due to its small footprint and mobility, the KTI Underground Chiller can be easily relocated at any time. This allows the weather chiller to be quickly deployed where it is needed most.

The KTI Underground Chillers are used as weather cooling machines especially for the expansion of underground mines.

Plant information

The KTI Underground Chiller is a mobile and robust weather cooling machine, which can withstand even the harshest conditions in underground mining. Due to the robust design and workmanship, this weather cooling maschie is superior to any conventional water cooler on the market:
  • Due to the very compact dimensions of the KTI Underground Chiller, it can be easily transported down through the mine shaft be used. The robust steel frame with protective housing also allows transport underground through the mine to any "hotspot" where cooling is required.
  • The weather cooling machine is used as turnkey solution delivered. Only the water connections and the power supply must be connected on site.
  • Thanks to its redundancy, the KTI Underground Chiller offers a exceptional efficiency and reliability. Three semi-hermetic piston compressors with the mexxFlow valve plate systemÂź guarantee a constant supply of the required refrigeration capacity.
  • Likewise, the Efficiency around 15% higher compared to conventional reciprocating compressors.
  • The operation takes place via a waterproof switching and control unitwhich is equipped with a color touch control monitor. Via a TCP/IP connection it is possible to Remote access the plant is controlled.

Maximum mobility, flexibility and efficiency

The KTI Underground Chiller is the answer to the challenge of developing a chiller that can operate underground. With which heat removal can be achieved either by using water from a spray chamber, from a cooling tower or even the contaminated water from the underground network that must be pumped to the surface. Weather chillers can also be used on the surface and moved underground at a later date. The Underground Chiller can be operated in high efficiency mode (COP = 5.77) using water from the underground network with water temperature of +17 ° C for heat removal (condensation). Alternatively, the standard mode is available using water from an underground cooling tower or spray chamber (COP = 3.89) with water inlet of +33 ° C.

Expert knowledge

The KTI Underground Chiller is unique on the market. With it, we have developed a weather cooling machine that our customers are enthusiastically using. Due to its compactness and plug-and-play design, we have already been able to help customers who needed a short-term solution so as not to interrupt the tunnelling work in underground mining.

The performance and reliability has always convinced our customers and with the Underground Chiller KTI has once again developed a product that has been missing for a long time. The Underground Chiller is also a perfect complement to KTI's plate ice plants used for surface mine cooling.
