Basic Information
View and Options
The views of standard NG series dry coolers are shown on
Pic.C.1. and C.2 below.
Dry cooler Options
•Capacity. NG series dry coolers range broadly in their
capacities, which depends on factors including physical
size, fluid flow rate, glycol concentration and ambient
conditions. See submittal for specific capacity of your
equipment.
•Coils and Fans - single and multi fan and coil combo.
oPic. C.1 shows single fan dry coolers: NG-Z, NG-
V-01 and -02 are “single fan – single coil” type,
NG-V-11 is “single fan – two coil” cooler.
oExcept for NG-V-31 (Pic.C.2 - a), all the multi-fan
coolers (see Pic.C.2) are comprised of number
(up to six) of NG-V-12 (Pic.C.2 –b) coolers
(mounted on the same frame, piped, wired and
operating as one single unit).
oCooler capacity and number of fans are
reflected in its type/nomenclature: Pic. C.2-c
shows NG-V-62 cooler, comprised of six “two
fans –two coils” NG-V-12 sections.
•Fan type. NG series dry coolers have EC motor fans,
varying speed via 0-10vdc signal. Legacy models pre-
2020 may have been equipped with two-speed fans. See
submittal and wiring diagram.
Cooling media. Typically, water-glycol (rust inhibitor-infused
food-grade propylene glycol is used) mixture is used as
cooling media, with recommended concentration of 35% to
prevent pipe bursting. However higher or lower
concentrations could be used. Refer to dry cooler main label
for details on glycol type, ratio etc.
Pic. C.1

Attention: Glycol Concentration
NOTE. Equipment capacity is typically rated for
35% prop. glycol concentration in water mixture,
however dry coolers may be sold for different
specified concentrations. Be careful when
changing glycol concentration in the field as the
pump may become improperly sized as a result
of different required fluid flow rate. Contact the
factory for more information.

Dectron Dry Cooler OMM 6September 2020
External Systems Connection
Normally, the only systems need to be connected to the dry cooler are cooling media piping and electrical power
(control wiring connection is required also, unless dry cooler is self-controlled).
Cooling Media Piping Connection. Normally dry cooler is provided with two piping connections (one –inlet,
another –outlet) for cooling media. Connections are normally identified/labeled in respect to cooling media flow
direction (hot/warm media entering the dry cooler –IN, cool media leaving the dry cooler –OUT).
•If dry cooler is provided with pump package option, cooler connections might be located within pump package
–refer to specific dry cooler labels and submittal documentation (drawings etc.).
Electric Power and Control Connection. Electric power is normally brought to the dry cooler disconnect (if cooler is
equipped with one) or to power distribution block, located in cooler’s electrical box. Control wiring is normally
brought to the control terminals within electrical box.
•Dry coolers, equipped with multiple electrical boxes, normally required power and control connection only to
one box (indicated as”main”) – power and control wiring between boxes is normally done at the factory.
•Self-controlled dry coolers normally do not require external controls connected.
Equipment Specific Data
Specific information for individual dry cooler is provided in
the following methods:
Main Label (Pic. C.3):the manufacturer tag attached to the
dry cooler, that includes its most critical data:
General data including Serial Number and Dry cooler
Model (nomenclature)
oSerial Number is usually composed of 8 digits.
Additional letter “A”, placed at the end of
serial number, usually indicates that given dry
cooler is provided together with another
equipment it serves (dehumidifier etc.).
Operational data:
oElectrical (voltage, amp draw, HP etc.)
oCooling media (GPM, connection size etc.)
Note: The main label shown above is just an example.
CAUTION! Current manual refers to/depicts general/default external systems connection location. For details
regarding specific dry cooler’s connections (location/elevation, piping sizes, flow direction, wiring terminals etc.),
refer to the submittal documentation as well as dry cooler diagrams, labels and stickers.
Attention! Equipment Clearances!
CAUTION! Proper clearances should be maintained for adequate airflow and heat rejection, as well as for
maintenance and service of the equipment! Generally, up to 36” sides (all around) and 96” top clearances are
required. For more information on clearances as well as equipment dimensions and other details, refer to the
submittal documentation.

Labels and Stickers: attached normally to indicate dry cooler external systems connections (piping, electrical etc.),
terminals designation, to display warning etc.
Wiring Diagrams:typically, attached to the interior side of the dry cooler main electrical panel, depicting control
and power wiring.
Operation and Control
Dry cooler rejects the heat, absorbed by the cooling media (water etc.) from the external system(s) that dry cooler
serves, to the outdoor air.
Operation and Media Flow
Dry cooler operation is quite simple:
•Upon the command (when heat rejection is needed) dry cooler engages its fan(s) to establish the airflow
across the coil(s).
oDepending on the type of fans (modulating EC-type or two-speed), control type and command
received, cooler total airflow is adjusted by varying fan(s) speed and/or number of operating fans.
•Cooling media flow must be established also –either by separately controlled pump (part of the external
system) or by the built-in pump package pump. In latter case, pump would engage with the fan(s) and will stay
engaged while the command exists (while at least one fan is running).
•Until call for heat rejection is satisfied and command to dry cooler is removed, fan(s) and pump will run; once
command removed, all fans and the pump will stop.
Pic. C.4 below shows schematic layout of dry cooler operation and media (air and water/glycol) flow.
For more details on dry cooler piping connection refer to Installation Manual, submittal documentation etc. as well
as local Codes and proper field practices.
Pic. C.4

Dectron Dry Cooler OMM 8September 2020
Control
There may be some different types of controls used with NG series dry coolers.
Fan type:
•Modulating (EC-type) fans are capable of varying their speed (from 0 to 100%) based on 0-10VDC signal. These
fans are standard on NG series dry coolers built since 2020 and may be found on some built prior.
•Two-speed fans are capable of running in two alternative speed (low or high); normally done by switching
between “star” and “delta” motor wiring (fans are pre-wired from the factory to switch from one to another,
based on respective contactor –low or high speed –being engaged). These fans typically are used on legacy
mid- to large size multi-fans dry coolers.
oStaging. Standard (and the most simplistic) staging uses just two stages –low speed and high speed –
where all fans are running together (in low or high speed, as commanded).
Control Type (all control types referenced below are applicable to all fans type described above):
•Externally controlled Dry cooler. Fan(s) speed signal (modulating or stage switch-over) is provided from
external system (usually –the one that dry cooler serves, to satisfy said system operational requirement). This
is typical for dry cooler serving single systems. Typical signal type for this control type are modulating (0-
10VDC) or two-speed switch-over (however, other arrangements are available). It may control the fan
according to head pressure or another control method chosen by installer.
•Self-controlled (“stand-alone”) Dry cooler. Fan(s) speed signal (modulating or stage switch-over) is based on
built-in control device. Most commonly used one is an aquastate, monitoring temperature of the cooling
media (water/glycol mixture), leaving the dry cooler.
oTypically, aquastat is pre-set to maintain entering cooling media temperature at certain level: the
sensor issues the signal to start the fan(s) and increase their speed as temperature increases (and,
respectively, reduce fans’ speed when temperature reduces). Typically, this signal is 0-10vdc –it
could be accepted by EC-type fans directly or translated into staging signal with additional device (this
allows to set more than two stages to finetune dry cooler operation).
Dry cooler is normally provided with the wiring diagram, depicting its specific control schematic –refer to it as
needed.

Fig. 1, 2 and 4 show NG-V type dry coolers (two, six and single-fan models, respectively), while Fig. 3
shows NG-Z type dry cooler.
Examples show all/most available options (like pump package etc.); some of shown options may not be
present on your dry cooler –refer to submittal documentation as needed.
•Cooling airside coil(s) (31) (where heat from glycol mixture is rejected to the ambient air) is mounted onto
metal frame, upstream (before) the fan(s) (32), that pulls the air through the coils to absorb the heat.
oDepending on the equipment type and required capacity, dry cooler may have one or multiple coils
and fans –refer to Views and Options (Basic Information chapter).
•Dry cooler piping connections (33) are identified in respect to cooling media flow direction (hot/warm media
entering the dry cooler –IN, cool media leaving the dry cooler –OUT);
oIn some cases, dry cooler piping connection(s) may be located within pump package box (37), if dry
cooler is provided with one.
oPiping connection location may vary –refer to particular cooler labels, stickers, submittal and other
documentation.
oDry cooler manifold/connection, normally, is not equipped with isolating valves, filters etc. (this also
applies to pump package, if dry cooler is equipped with such option; see pump package layout
below).
•For NG-Z type (Fig. 3) ONLY! Said dry cooler ships with set of legs (34) to provide sufficient space between
horizontal mounting surface and airflow intake. On-site assembly is required for these legs. For more details
on the installation refer to the Installation Manual.
•Electric power is normally to be brought to disconnect (35) (if cooler is equipped with such), which feeds it to
the electrical box (36), that contains dry cooler power and control apparatuses.
oDepending on dry cooler specifics, location of electrical box may slightly differ; in some cases,
electrical box may be incorporated into pump package or located on the opposite side of the dry
cooler.

Electrical Box –Power and Control
Dry cooler power and control wiring and
apparatuses (transformer, contactor(s), fuses,
wiring terminals etc., as applicable) are located
in the electrical box, shown on Pic. D.2: typical box of dry
cooler type NG-Z (a) and type NG-V (b):
•In some cases dry cooler electrical box could be
incorporated within pump package.
•NG-V type dry cooler with multiple fans would have
multiple boxes (typically –one box per one pair of
fans).
oMultiple electrical boxes on one dry cooler are
normally connected to each other at the
factory, so external power and control wiring
has to be brought only to one (main) electrical box.
•Depending on the specifics of the dry cooler (size, type of fans, control method etc.), electrical box layout and
components may vary –refer to your dry cooler submittal, wiring diagram and other documentation.
Pump Package
If equipped with such option, dry cooler would have a pump package box. Pic.D.3 below shows general layout of
pump packages, used for NG-V model dry coolers. Note, that the package could be mounted onto the dry cooler
directly (standard) or provided separately.
Dry coolers Pump Package
Dry coolers, if equipped with such option, would have a pump package box. Pic.D.6 below shows general layout of
pump packages, used for NG series: NG-Z (a) and NG-V (b) type, respectively. Note that the package used with NG-
V coolers is normally mounted onto the cooler directly, however, it also could be provided separately.
•Pump (38) establishes glycol mixture circulation through the dry cooler and dehumidifier;
•Expansion tank (39) compensates for temperature-based glycol/cooling fluid volume fluctuation;
•The pump package electrical sub-panel (40) contains the pump package electrical power and control
apparatuses.
oIn some cases, pump package electrical sub-panel may contain power and control apparatuses for the
entire dry cooler (fan(s) and pump package).
•The pump package manifolds are usually equipped with pressure gauges, automatic air venting and manual
draining/charging valves.

•Straighten any coil fins that have been bent during the cleaning process
•Replace all panels and parts and restore electrical power to the equipment
Dry Cooler Service.
Normally dry coolers are filled with glycol mixture to prevent the system and the dry cooler from freezing and
potentially rupturing pipes when exposed to temperatures below freezing point.
When dry cooler is used with media that, when exposed to low temperatures, could freeze (pure water or very
low-percentage glycol mixture), one way to protect the equipment is to drain it (also known as “winterization” of
the equipment).
Though dry cooler itself is normally equipped with means to be drained properly/fully, it is recommended to have
same means in place for entire system/equipment dry cooler serves:
•Have each local high point of the system equipped with means to bleed the air (air bleeding valve etc.)
•Have each local low point of the system equipped with means to drain the fluid.
