Correct
Q: What is the expected payback time of an investment in system optimisation?
A: 1-5 years
Correct
Q: How high is the suction lift of the self-priming CM pump?
A: Up to 8 metres
Correct
Q: Why is ammonia an efficient coolant?
A: Ammonia is able to absorb large amount of heat when it evaporates.
Correct
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.
Correct
Q: How have temperature control systems traditionally been regulated?
A: Constant speed pumps and throttling valves regulating the amount of water entering the heat exchanger.
Correct
Q: Which component is often ‘the weakest link’ in centrifugal pumps?
A: Shaft seal
Correct
Q: Which of the following isn’t one of the main benefits of the CM pump range?
A: External control
Correct
Q: Which temperature control systems hold the greatest potential for optimisation?
A: Three way valve Regulated temperature control systems that adapts operation according to the load.
