DX COOLER 300 (21 BAR) PSIG DWP WATERSIDE
– The waterside will be of 300 PSIG (21 bar) instead of
the standard 150 PSIG DWP. 300 PSIG R.F. anges are
included on the DX cooler nozzles. (Factory-mounted)
The companion anges will be eld-supplied by oth-
ers.
FLANGES (ANSI/AWWA C-606 COUPLINGS TYPE)
– Consists of (2) ange adapters for grooved end pipe
(standard 150 psi [10.5 bar] cooler). (Not available on
optional DX cooler 300 PSIG DWP waterside.) (Field-
mounted)
FLOW SWITCH – The ow switch or its equivalent must
be furnished with each unit.
150 PSIG (10.5 BAR) DWP – For standard units.
Johnson Controls model F61MG-1C Vapor-proof
SPDT, NEMA 3R switch (150 PSIG [10.5 bar] DWP),
- 20°F to 250°F (- 29°C to 121°C), with 1” NPT
connection for upright mounting in horizontal pipe.
(Field-mounted)
DIFFERENTIAL PRESSURE SWITCH – Alternative
to an above mentioned ow switch. Pretempco model
DPS300AP40PF-82582-5 (300 psi max. working pres-
sure), SPDT 5 amp 125/250VAC switch, Range 3 - 40
PSID, deadband 0.5 - 0.8 psi, with 1/4” NPTE Pressure
Connections.
HYDRO-KIT – Factory installed Hydro-Kit suitable for
water glycol systems with up to 35% glycol at leav-
ing temperatures down to 20° F. The Hydro-kit option
is available in a single or dual conguration (dual as
standby duty only), with totally enclosed permanently
lubricated pump motors.
The hydro-kit option comes standard with a balanc-
ing valve, ow switch, pressure ports, suction guide,
strainer, bleed and drain valves and frost protection.
Expansion tanks are optional within the Hydro-Kit op-
tion.
CONDENSER AND CABINET OPTIONS
Condenser coil protection against corrosive environ-
ments is available by choosing any of the following
options. For additional application recommendations,
refer to FORM 150.1 -ES1. (Factory-mounted)
POST-COATED DIPPED CONDENSER COILS
– The unit is built with dipped-cured condenser
coils. This is the choice for corrosive applications
(with the exception of strong alkalis, oxidizers and
wet bromine, chlorine and uorine in concentrations
greater than 100 ppm).
ENCLOSURE PANELS (UNIT) – Tamperproof En-
closure Panels prevent unauthorized access to units.
Enclosure Panels can provide an aesthetically pleasing
alternative to expensive fencing. Additionally, for proper
head pressure control, Johnson Controls recommends
the use of Condenser Louvered Panels for winter ap-
plications where wind gusts may exceed ve miles
per hour. The following types of enclosure panels are
available:
WIRE PANELS (FULL UNIT) – Consists of welded
wire-mesh guards mounted on the exterior of the unit.
Prevents unauthorized access, yet provides free air
ow. (Factory-mounted)
WIRE/LOUVERED PANELS – Consists of welded
wiremesh panels on the bottom part of unit and lou-
vered panels on the condenser section of the unit.
(Factory- mounted).
LOUVERED PANELS (CONDENSER COIL ONLY)
– Louvered panels are mounted on the sides and
ends of the condenser coils for protection. (Factory-
mounted)
LOUVERED PANELS (FULL UNIT) – Louvered
panels surround the front, back, and sides of the
unit. They prevent unauthorized access and visu-
ally screen unit components. Unrestricted air ow
is permitted through generously sized louvered
openings. This option is applicable for any outdoor
design ambient temperature up to 115°F (46°). (Fac-
tory-mounted)
COIL END HAIL GUARD – Louvered panel attached
to exposed coil end. (Factory-mounted)
