14. PowerStream / Jonathan Smith / 09-2010 HPC PowerStream SA – Options – Heat Exchanger Why do we offer it? i PowerStream is compact and can generate heat when used with some small machines and pump configurations: Sliding head machines with small tanks < 300 litres Sliding head machines with small tanks < 300 litres High flow rate pumps (up to 45 L/min) High flow rate pumps (up to 45 L/min) High pressure pump run continuous but not used by machine tool High pressure pump run continuous but not used by machine tool ii Thermal rise in coolant temperature Designed to maintain ambient temperature

15. PowerStream / Jonathan Smith / 09-2010 HPC PowerStream SA – Options – Heat Exchanger What does it do? i Maintains ambient temperature (Note: a chiller maintains set temperature) (Note: a chiller maintains set temperature) ii Helps stabilise temperature on machines with small tanks using HPC iii Directly cools coolant returned off pressure relief valve (a high temperature source due to friction across the valve) (a high temperature source due to friction across the valve) Designed to maintain ambient temperature

17. PowerStream / Jonathan Smith / 09-2010 HPC PowerStream SA – Additional Set Pressure Option We can offer additional pressure relieve valves to the various outputs which means they can be independently controlled from the system pressure. This means for example when port 1 is opened it produces, for example 70 bar but with the addition of a pressure relief valve to port 2 when the machine calls for port 2 it produces a different pressure, for example 40 bar (see below). It is important to note however, it is only possible to have one pressure running at any onetime… it is not possible to run both 70 and 40 at the same time. When the machine calls for port 1 the output pressure to the machine is 70 bar When the machine calls for port 2 the output pressure to the machine is 40 bar (although the out pressure of our PowerStream system remains the same)
