Q: Which load profile will benefit the most from a demand driven control system?
A: Low flow rate with relatively few peak periods during the day.
Q: Which load profile will benefit the most from a demand driven control system?
A: High flow rate with relatively few low flow periods during the day.
Q: Which load profile will benefit the most from a demand driven control system?
A: Varying flow rate with relatively often periods with full flow and no flow.
Q: What is the most efficient and simple way of controlling heating, cooling and refrigeration systems?
A: Intelligent three way valves controlling the amount of water to the pump and heat exchanger accordingly.
Q: What is the most efficient and simple way of controlling heating, cooling and refrigeration systems?
A: 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.
Q: What is the most efficient and simple way of controlling heating, cooling and refrigeration systems?
A: Thermos element three way valves controlling the amount of water to the heat exchangers.
