1. AFE SELF CONTAINED AIRFOG SYSTEMS
A. AFE MINI SYSTEMS
(1)
AFE MINI systems are self-contained packaged systems that include all necessary
components.
(2)
They require the following connections:
(a)
3/8” O.D. plastic or soft copper water supply line rated at a minimum of 25
psig.
(b)
1/4” O.D. plastic or soft copper air supply line rated at a minimum of 90 psig
(c)
Isolation valves for both air and water lines
(d) Mounting
hardware
(e) Support
anchors
(f)
1/4” lag bolts
(g)
120 VAC standard electrical receptacle
(h)
Humidity control device (Humidistat)
(3)
The best location for a MINI is on a wall or column with the mist discharging down
an aisle where it will not condense on solid surfaces. A clear run of at least 15 feet
forward of the nozzles is normally a sufficient distance for complete absorption.
Adiabatic cooling may be uncomfortable to people occupying workstations directly
beneath the Mini systems.
(4)
The Mini nozzles must be a minimum of 6 feet above the floor and 36” below the
ceiling in order to prevent condensation on these surfaces. See Figure 1 Mini
Installation.
(5)
Four accessible internal mounting holes are located in each corner of the rear
panel. The mounting procedure is:
(a)
Either attach the supplied mounting bracket hardware or bolt panel directly
onto the wall surface via the mounting holes.
(b)
Place the panel level against the surface and mark the drill holes.
(c)
Remove the panel and drill the holes (hole size to match field supplied lag
bolts and anchors).
(d)
Replace the panel and secure using bolts.
(6)
Install water and air supply lines. Both water and air lines should have an isolation
valve installed near the unit. Water connection at the unit is designed for 3/8”
plastic tubing but if soft copper pipe is to be used, replace the plastic sleeve in the
fitting with the supplied brass sleeve. The air connection is designed for 1/4”
plastic tubing. Figure 2 Plumbing End Connections illustrates details of the
interfaces.
