INTRODUCTION
The SMC range of compressed air dryers are designed to remove moisture from
compressed air by utilising state of the art technology to obtain dewpoints of -40°F
PDP and by appropriate de-rating -100°F PDP.
SMC dryers have been designed to require minimal maintenance and can be installed
virtually anywhere.
The SMC dryer consists of upper and lower head assemblies joined together with an
aluminium extrusion containing twin internal chambers. The upper head assembly
contains inlet and outlet manifolds, pre-filter and autodrain. The lower head assembly
contains two exhaust valves and a passive shuttle ball valve. Contained in each
internal chamber is a combination desiccant / after-filter cartridge. During operation
one chamber is on-line (drying) while the other is regenerating, using the Pressure
Swing Adsorption (PSA) process.
Pressure Swing Adsorption (PSA)
A small percentage of dried air is taken from the dryer outlet flow and is used to
regenerate the saturated chamber by expanding the dried air from line pressure to
atmospheric pressure. During this process, the moisture is physically removed from
the regenerating chamber and vented to atmosphere through the exhaust.

2.0 INSTALLATION (refer to figure 1)
2.1 ESSENTIAL INFORMATION
Care must be taken to ensure that the dryer is not subject to flows (even peaks) in
excess of the dryers rated capacity, e.g. dryers downstream of an air receiver have
increased potential to be overflowed.
The dryer can be installed free standing, secured to the floor via the fastening points
provided in the base or secured to a wall using optional brackets.
The control enclosure (A) must be at the bottom and the dryer must be installed
vertical and level.
Two inlet and two outlet connections are available at the top of the dryer to enable
connection from either left or right. Unused connections (B) and (C) must be sealed
with the threaded plugs provided. Suitable rated pipe and connections must be used
for the installation. All pipework must be secure and safely positioned.
The purge flow is factory set for 87 psi g minimum operating pressure. Should the
minimum pressure requirement be different, the purge flow must be reset by a Sullair
engineer or a Sullair approved agent.
Ensure the dryer is electrically connected to a supply suitable for the unit. See wiring
diagram printed in 2.3 Electrical Details.
1. Filtration
A 0.01 micron pre-filter is contained within the upper head assembly. 1 micron after-
filters are integral within desiccant cartridges screwed into inserts in the upper head
assembly. Filters must be maintained by Sullair or a Sullair approved agent.
2. By-pass Line (D)
A by-pass line, 3/8" NPT (D) ensures complete safety during maintenance and
enables a continuous supply of compressed air to be maintained if required. It should
be remembered that air bypassing the dryer is dirty untreated air.
3. Valves (E, F, G)
Isolation valves, 3/8" NPT are recommended on the inlet (E), outlet (F) and bypass (G)
lines at the positions indicated in Figure 1.

2.5 RUNNING THE DRYER WITH A MINIMUM PRESSURE BELOW 102 PSIG
If the dryer is to be run with a minimum pressure of 102psig (7 Bar g) an alteration to
the timer board is required.
To carry out the alteration,ensure the electrical supply is isolated, lie the dryer on its
back, to gain access to the control base. Remove the large plate to gain access to the
timer board. Move electric jumper from Position 1 to Position 2, as shown.

3.0 START-UP AND OPERATION
3.1 INTIAL STARTUP
Ensure a suitable supply of compressed air between 58 psi g and 175 psi g pressure
is available and check that the dryer cannot be overflowed. Inlet temperature must be
between 34°F to 122°F at all times.
IMPORTANT NOTE
Ensure all valves are opened and closed gradually.
Proceed as follows: (Refer to figure 1)
3.2 WITHOUT THE BY-PASS LINE (D)
Close inlet (E) and outlet (F) valves.
Introduce air to the dryer by gradually turning the inlet valve (E) until fully open.
Allow dryer to fully pressurise, then gradually open the outlet valve (F).
Switch on the electrical isolator, the yellow ‘power on’ LED and the green ‘correct
operation’ LED will illuminate and the dryer will commence cycling. The dryer is now
on stream.
3.3 USING THE BY-PASS LINE (D)
With the inlet (E) and outlet (F) valves closed and the by-pass (G) valve open,
introduce air to the dryer by gradually turning inlet valve (E) until fully open.
Allow the dryer to fully pressurise, then open the outlet valve (F) while simultaneously
closing the by-pass valve (G).
Switch on the electrical isolator, the yellow ‘power on’ LED and the green ‘correct
operation’ LED will illuminate and the dryer will commence cycling. The dryer is now
on stream.
3.4 NORMAL OPERATION
Following the start-up procedure the operation of the dryer is fully automatic and
requires no further attention until shut down.
The yellow ‘power on’ LED and the green ‘correct operation’ LED should be illuminated
continuously.

The dryer contains two desiccant chambers, while one chamber is drying the
compressed air (adsorption), the other chamber is simultaneously undergoing
regeneration (desorption). At a predetermined time both exhaust valves close and
repressurisation begins. Every three minutes the chambers are reversed in function,
this is the changeover point. Changeover is characterised by an immediate venting of
compressed air from the chamber entering regeneration.
The dryer can be shut down at any point in its cycle and when restarted will enter an
automatic repressurisation stage. After repressurisation the cycle will commence at
the point at which it stopped.
NB
If power is switched on, the dryer will enter an automatic repressurisation stage at the
point at which it stopped.
3.5 SHUT-DOWN PROCEDURE
To Depressurize the Dryer
Prior to isolating the electrical supply close the outlet valve (F) while simultaneously
opening the by-pass valve (G) if fitted. Close the inlet valve (E). The dryer will now be
isolated from mains pressure. Cycle the dryer for a minimum of 3 minutes to ensure
the dryer vents and is completely depressurized. When the dryer is completely
depressurized, isolate the electrical supply.
NB
The by-pass valve (G) should only be opened if the dryer is undergoing maintenance.

4.0 MAINTENANCE
Daily
• Ensure the yellow ‘power on’ LED and the green ‘correct operation’ LED are
illuminated.
Weekly
• Check dryer seals, fittings and pipe work for air leaks.
• Ensure correct operation of inlet filtration condensate drainage.
The Combination desiccant / after-filter cartridges have a finite life dependent upon
operating conditions.
Cartridge status is indicated
Cartridges require changing and audible alarm will sound every 6 seconds.
NOTE: Temporary resetting of the alarm to prevent nuisance noise is possible after
alarm has sounded for the first time. This is done by depressing once the reset button
located inside the control enclosure, accessed by removing the black insert on the
side. The alarm will be muted for a 24 hour interval until the dryer has been serviced
and the reset sequence completed.
Servicing of the dryer must only be carried out by Sullair personnel or trained Sullair
service agents.

INTRODUCTION
La gamme SMC de sécheurs d’air comprimé est conçue pour éliminer l'humidité de
l'air comprimé en utilisant une technologie de pointe pour obtenir des points de rosée
sous pression de -40 °F et, par un déclassement approprié, de -100 °F.
Ces sécheurs SMC ont été conçus pour demander un entretien minimal et peuvent
être installés virtuellement n’importe où.
Le sécheur SMC se compose d’ensembles de têtes haut et bas assemblés par un
profilé extrudé d’aluminium contenant des chambres internes jumelles. L’ensemble de
têtes haut contient des collecteurs d’entrée et de sortie, un pré-filtre et une purge
automatique. L’ensemble de têtes bas contient deux soupapes d’échappement et un
sélecteur de circuit passif à tournant sphérique. Chaque chambre interne contient une
cartouche combinée déshydratant / post-filtre. En exploitation, une chambre est en
ligne (en séchage) tandis que l'autre est en régénération, par le processus
d'adsorption modulée en pression (AMP).
Adsorption modulée en pression (AMP)
Un faible pourcentage d’air séché est extrait du courant de sortie du sécheur et sert à
régénérer la chambre saturée en détendant l’air séché de la pression de canalisation
à la pression atmosphérique. Lors de ce processus, l’humidité est éliminée
physiquement de la chambre en régénération et évacuée dans l’atmosphère via
l’échappement.

2.0 INSTALLATION (se reporter à la figure 1)
2.1 Informations essentielles
Il faut faire attention de s’assurer que le sécheur n’est pas soumis à des débits (même
en crête) dépassant sa capacité nominale, par exemple que les sécheurs en aval d’un
collecteur d’air comprimé présentent un risque accru d’être débordés.
Le sécheur peut être posé au sol, fixé au sol via les points de fixation de sa base ou
fixé au mur par des équerres en option.
Le boîtier de commande (A) doit se trouver au fond et le sécheur doit être installé
vertical et plan.
Deux raccords d’entrée et deux raccords de sortie sont disponibles en haut du
sécheur pour permettre le raccord à gauche ou à droite. Les raccords non utilisés (B)
et (C) doivent être scellés par les bouchons filetés fournis. Des tuyaux et raccords
convenablement évalués doivent être utilisés pour l’installation. Toute la tuyauterie
doit être sûre et positionnée de façon sécurisée.
Le débit de purge est réglé en usine à 7 psi eff de pression de service minimale. Si la
pression minimale requise s’avérait différente, le débit de purge doit être réinitialisé
par un ingénieur de Sullair ou un agent agrée par Sullair.
S’assurer que le sécheur est raccordé électriquement à une alimentation qui convient
pour l’unité. Voir le schéma de câblage imprimé en 2.3 Détails électriques
1. Filtration
Un pré-filtre de 0,01 micron est contenu dans l’ensemble de têtes haut. Des post-
filtres de 1 micron sont intégrés dans les cartouches déshydratantes vissées dans les
pièces rapportées de l’ensemble de têtes haut. Les filtres doivent être entretenus par
Sullair ou un agent agréé par Sullair.
2. Conduite de dérivation (D)
Une conduite de dérivation, 3/8" NPT (D) garantit une complète sécurité lors de
l’entretien et permet de maintenir une fourniture continue d’air comprimé si
nécessaire. Il faut se souvenir que l’air qui contourne le sécheur est un air sale et non
traité.
3. Vannes (E, F, G)
Des vannes d’isolement, 3/8" NPT sont recommandées sur les conduites d’admission
(E), de refoulement (F) et de dérivation (G) aux positions indiquées à la figure 1.
