FLEX offers "true operational modularity
p
y"
which allows maintenance on any individual module without
system shutdown. Scheduling for chiller shutdowns becomes
a thing of the past.
The modules are simple to assemble and install and require
a minimal amount of site work. They are ex tremely “user
friendly” in installation, operation and maintenance respects.
All models come with aesthetically pleasing enclosures
for minimal noise transmission.
Modular Unit Design - FLEX Series
X
The
FLEX Series modules are designed to be refrigerant-
X
convertible. The system is to be comprised of individual
chiller sec tions that are modular in design. Modules must be
comprised of individual refrigerant circuits, compliant with
ASHRAE 90.1 operating on either R-22 or R-407C. Each
module is to be less than 34” in width to allow for maneuver-
ing through narrow openings. Each module’s length shall not
exceed 43 5/8” to min

Module Isolation and Room Footprint Requirements
All service and maintenance isolation valves are contained
within the module footprint dimensions (34" wide x 43 5/8"
deep). Water isolation valves are recessed within the 6"
header condenser and evaporator water piping dimensions
front and rear to prevent valve damage and to minimize ser-
vice clearances. All isolation valves are designed within the
module footprint dimensions. Valves which extend beyond
the main water header dimensions can result in an increase in
the equipment room footprint or add to the service clearance
dimensions. A motorized valve requires a 1 1/2" extension for
variable primary fl ow.
Hydronic Design
The chilled water piping on each module is pre-insulated at
the factory with 3/4” closed cell foam rubber. Insulation
(3/4") on the chilled water header connection fl anges is to
be applied in the fi eld by the installer, after the modules are
bolted together on site. Each module is factory supplied with
isolation valves on all water circuits to allow repair or main-
tenance without interrupting service of the entire system.

er system bolted in series to maintain constant and full fl ow
