• Two or three Maxi-Smarts in parallel
• A safer solution for the same price
Installing two parallel machines means halving the probability of a total shutdown in the surgery: this
is the reason why this solution is recommended. If we consider machines of equal performance,
two machines that together serve 30 dental units with simultaneous suction, will normally cost the
same as a machine with double fl ow serving the same number of units, always operating simulta-
neously.
• Operation
When the fi rst surgery starts using suction, the programme starts the machine with fewer operation
hours. Each time another dental unit starts suction, the units automatically increases its rotation
speed; before a total of 15 dental units is reached, the second Maxi-Smart is switched on. The two
suction units will then share the work-load evenly based on the programmed head and fl ow rate,
while keeping power consumption as low as possible. Before the two machines reach maximum
rotation speed, the third machine will be started. The programme follows the same method in the
opposite direction, when the number of dental units decreases. If the system is large compared to
the total number of users, the programme will always start the second or third machine before the
ones in operation reach their maximum operating speed. This precaution prevents stress on the
motor and keeps power consumption down. With this new technology you will no longer need to
buy a smaller system to save on purchase cost, because there will be no real saving; in addition
there will be an economic advantage over time in terms of life of the suction units and power con-
sumption.
