02.
Q: What is the expected payback time of an investment in system optimisation?
A: 1-5 years
02.
Q: What is the expected payback time of an investment in system optimisation?
A: System optimization is rarely economical valuable but should be done due to environmental concerns
03.
Q: Why does a cooling system that uses propylene glycol as coolant demand pumps with oversized motors?
A: The viscosity and density of propylene glycol is higher than tap water.
03.
Q: Why does a cooling system that uses propylene glycol as coolant demand pumps with oversized motors?
A: The viscosity and density of propylene glycol is lower than tap water.
03.
Q: Why does a cooling system that uses propylene glycol as coolant demand pumps with oversized motors?
A: Propylene glycol has a lower specific heat capacity and therefor requires a higher flow.
