Simplified example of a closed cooling system
The bypass valve is necessary for the temperature control and protection against condensation. The diaphragm
accumulator ensures a quite constant pressure in the cooling system even when great variations occur in the
coolant temperature. The pump provides the continuous coolant flow; it is recommended that such pump be
made of stainless steel. The acceptable differential pressure in the cooling circuit in relation to the atmosphere
must not exceed 6 bar. That must be guaranteed by the over pressure valve.
ATTENTION!
The hoses that connect the cooling system to the UP11W G2 must not conduct electricity.
ATTENTION!
The acceptable differential pressure in the cooling circuit in relation to the atmosphere must not
exceed 6 bar.
ATTENTION!
The cooling of the UP11Ws G2 must not be connected in series in the circuit of the cooling system.
