Cooling Unit VT.ZUCH-1 is intended to use in closed (liquid circulation) cooling systems. It is mainly used in the machines cooling systems and other equipment working in underground excavations, including potentially explosive atmospheres. Cooling aggregate, by its connection into cooling modules of various types of mechanical devices (e.g. electric motors, hydraulic coolers, mechanical transmissions), enables efficient heat dissipation to the atmosphere. The aggregate can also be used wherever it is needed with assurance that is used in accordance to this manual and in correlation with technical parameters and with keeping required work conditions.
