6: Why does a cooling system that uses propylene glycol as coolant demand pumps with oversized motors?
The viscosity and density of propylene glycol is higher than tap water.
6: Why does a cooling system that uses propylene glycol as coolant demand pumps with oversized motors?
The viscosity and density of propylene glycol is lower than tap water.

6: Why does a cooling system that uses propylene glycol as coolant demand pumps with oversized motors?
Propylene glycol has a lower specific heat capacity and therefor requires a higher flow.
You can find the answer here >
7: What is the most efficient and simple way of controlling heating, cooling and refrigeration systems?
Intelligent three way valves controlling the amount of water to the pump and heat exchanger accordingly.
You can find the answer here >
7: What is the most efficient and simple way of controlling heating, cooling and refrigeration systems?
Intelligent pumps equipped with temperature sensors that measure the outlet temperature and signal the pump to regulate its flow accordingly – without the use of valves.
7: What is the most efficient and simple way of controlling heating, cooling and refrigeration systems?
Thermos element three way valves controlling the amount of water to the heat exchangers.
