FLOW CONTROLLER DESCRIPTION
The AFC series Flow Controller is a compact, easy to mount
polystyrene cabinet that contains 3-way valves and pump(s)
with connections for flushing, filling and pumping residential
geothermal closed loop systems. The proven design is foam-
insulated to prevent condensation. Full flow service valves
minimize pressure drop. One or two Grundfos pump models
UP26-99 or UP26-116 are available for a variety of unit flow
rates and loop layouts. Flow Controllers are designed for
systems that require water flow rate of up to 20 U.S. GPM
[1.26 l/s]. Unit and loop connections are designed for double
o-ring adaptor fittings for a variety of connection types
(fusion, threaded, barbed, cam). Pumps are 230VAC, 60Hz.
An attractive gray polystyrene cabinet with black pump(s)
provides an esthetically pleasing enclosure for pump(s) and
valves.
