Access:
11.1
A large galvanized, hinged, steel
access door 24" (711mm) wide and
42" (1066mm) high shall be located

cold water basin and fan plenum area.
Access doors shall be operable from

Collection Basin
:
12.1
The collection basin shall be heavy-
gauge galvanized steel. Suction
connections shall be equipped with
galvanized debris screens. A factory-
installed, float-operated, mechani-
cal makeup valve and waste water
blowdown line shall be included. A 4"
(101.7 mm) diameter PVC drain and
overflow shall be provided in each cell
of the tower. The basin shall include
a depressed section into which accu-
mulated silt can be flushed to permit
cleaning. The basin floor adjacent to
the depressed section shall slope
toward the depressed section to pre-
vent buildup of silt under the coil area.
12.2
Recirculation pump(s) shall be
mounted to the collection basin in
conjunction with a suction assembly.
Recirculation piping shall be schedule
40 PVC. A blowdown line with meter-
ing valve shall be connected directly to
the tower overflow.

Warranty
:
13.1
The fluid cooler shall be free from
defects in materials and workmanship
for a period of eighteen (18) months
from the date of shipment.
Q
Access doors on other manufacturer’s towers may be 18" wide
or smaller, which is unreasonably small for a human being.
Specifying the size of the door will cause those bidders to take
exception, alerting you to a potential maintenance headache. Two
doors are standard on all MH Fluid Coolers—one in each endwall.
The removable-standpipe type of overflow is valuable because
it provides a way to achieve flush-out cleanability. Other drains
may be as little as 1" (25mm) diameter, making flush-out cleaning
impractical at best.
Location of the coil in the lower portion of the MH Fluid Cooler
makes it much easier to access for cleaning and inspection.
