2900/1700-NXT SYSTEM 5 DUPLEX

Features include Fleck 2900/1700 3200NXT Simplex System with an electronic meter for each valve and includes two commercial brine tanks with the Clack 454 commercial shutoff valve.

Meter Immediate (Interlock) (2 – 4 Valves) This is a 2 to 4 unit system, each unit having a meter, and all in service. Only one unit is allowed in regeneration at a time. A unit regenerates immediately when the available volume of treated water drops to zero (0) and no other unit is in regeneration.

2900/1700-NXT SYSTEM 6 DUPLEX Features include two Fleck 2900/1700 3200NXT Simplex Systems with one 2" electronic meter for the system, also includes two commercial brine tanks with the Clack 454 commercial shutoff valve.

Meter Immediate Series (2 – 4 Valves) This is a 2 to 4 unit system, all in service, with one meter for the entire system. When the entire system volume of treated water drops to zero (0), it requests the first unit to go into regeneration. Then, when the first unit is done regenerating, the second follows, and so on.

2900/1700-NXT SYSTEM 7 DUPLEX Features include two Fleck 2900/1700 3200NXT Simplex Systems with one 2" electronic meter for the system, also includes one commercial brine tank with the Clack 454 commercial shutoff valve.

Meter Alternating (2 Valves) This is a 2 unit system, with only one unit having a meter and only one unit in service. When the volume of treated water drops to zero (0) in the unit in service, it requests regeneration. This causes the unit in standby to move to service. Then the unit requesting regeneration moves to standby and begins regeneration.

System 14 Meter Progressive (2 – 4 Valves) This is a 3 or 4 unit system, each unit having a meter, one unit in service and all other units in standby. As flow rates increase,units in standby go into service. As flow rates decrease units in service go back into standby until only one unit is in service. Only one unit is allowed in regeneration at a time. When the volume of treated water drops to zero (0) in the unit in service, it requests regeneration. This causes the unit in standby to move to service. Then the unit requesting regeneration moves to standby and begins regeneration.
