MODINE AIR13-111.5 Steam / Hot Water Convectors

MODEL NOMENCLATURE

Convectors

DESIGN BENEFITS
ENCLOSURE STYLES
Convector cabinets are available in four attractive and functional styles to fit a wide range of architectural requirements.

TYPE SL
Fully exposed convector designed for wall mounting. Features a louvered outlet grille in the Slope-Top that keeps debris from accumulating
on the top of the unit. The air inlet
is directed through the bottom to produce high outputs.
TYPE SF
This fully exposed floor unit has sloping outlet louvers and is designed for mounting to a sidewall. The air inlet is directed through the bottom front inlet louver. An optional arched inlet is available.
TYPE FL
This fully exposed floor-mounted convector is attached to the wall. The flat top design features front inlet and outlet louvers. The front panel is fastened to the liner.
TYPE PL
This fully recessed wall convector is designed to provide high outputs. The liner is recessed completely into the wall, and the front panel is fastened to the liner. Front inlet/outlet louvers are standard with sidewall mounted units.

HEATING ELEMENTS

Heating elements are available in three standard nominal depths: 4″ (2-tubes), 6″ (3-tubes), and 8″ (4-tubes). The assembly is protected by shield plates running the entire length of the element, and is supported in enclosure by a welded bracket to eliminate strain on piping or element. Fins of .010″ aluminum have integral collars to assure uniform spacing. Tubes are mechanically expanded into collars to permit maximum heat transfer. Headers are cast brass with top or bottom tappings. One header can be reversed to be mounted “up”, while the other is mounted “down”, for reverse piping applications.

ENCLOSURE CONSTRUCTION
Convectors are specially constructed to satisfy the requirements of strength, durability and safety in many different building applications. Cabinets are all suitably braced and reinforced and are available in heavy-gauge steel for special institutional applications.
END POCKETS
End pockets may be installed at one or both ends of the Cabinet Convectors. The heating element is shortened and a vertical baffle with element support is provided between the end of the element and the end of the cabinet. End pockets are available in 6″ or 8″ widths. (Note: Size unit capacities for actual coil length.)
Figure 4.2 – End Pocket Options

GRILLE OPTIONS
Convector front covers are available with louvered, perforated, or aluminum bar grille openings. All are designed to allow directional flow of air with maximum free open area. The four cover grille types are as follows:

• Die-formed louvered inlet/outlet. (Standard)
• Heavy-duty architectural inlet/outlet grilles with a deep-etched clear anodized (R-204) finish. The aluminum bar grille shall have vanes of continuous extrusion with a 15° deflection.
• Security inlet/outlet perforations with 1/8-inch diameter holes 1/4-inch staggered center lines.
• Arched inlet and a die-formed louvered outlet.

Figure 4.3 – Grille

ACCESS DOORS
Access door options are provided in the front panel of cabinet convectors for inspection or operation of valves, traps or air vents. These doors are hinged on one side with a heavy-duty hinge. A concealed 1/4-turn locking device may be provided with an optional Allen-head operator when security conditions dictate. Refer to page 14 for available door locations.
Figure 4.4 – Door Hardware

DESIGN BENEFITS

DAMPER
The damper assembly covers the entire outlet area of the enclosure and consists of a 20-gauge damper blade, which
is flanged top and bottom for additional rigidity. Damper assemblies are available with a knob operator or an optional tamper-resistant operator. The tamper-resistant operator functions with a simple Allen wrench and is particularly valuable in school or institutional settings where supervisory operation only is desired.
Figure 5.1 – Damper Options

COVER FASTENERS
The removable front cover shall be supported by a top panel clip and fastened at the bottom with a screw on each side. The standard screws are Phillips head with tamper-proof Spanner head screws available as an option.
Figure 5.2 – Fasteners

INSULATION
1/2″-thick fiberglass insulation is available on convector sides, tops, fronts or backs for special applications. (Top insulation does not apply to SF and SL models.)
SPECIAL FINISH
All convectors are thoroughly cleaned and phosphatized after fabrication and finished with a polyester-epoxy powder coating. As an option, cabinets may be finished in one of the standard decorator colors (see color chart 13-416).

DESIGN BENEFITS

Typical Piping Arrangements
VAPOR AND VACUUM SYSTEMS (STEAM)
Convectors are not recommended for one-pipe steam systems. Typical connections are shown below. Other arrangements, however, can be used.
Fig.1 –
This arrangement of down-feed hook-up is used when
the steam mains are above the Convectors with drops which are connected to the unit. This arrangement can be used only with freestanding units. The valve is shown inside the cabinet as it can easily be operated by lifting the removable front for an optional access door. A thermostatic control valve with a bulb in the inlet may be substituted for the hand-operated valve shown. The valve can also be installed outside the cabinet if desired. (Valve and piping installed by others.)

Fig. 2 – This shows an arrangement for an up-feed hook-up for semi-recessed or for freestanding units. A straight through tap of proper size may be substituted for the angle trap shown. This allows access to the valve.
On all steam systems, the convector element should pitch down to the return.

HOT WATER SYSTEMS
Two different arrangements are shown below for hot water piping connections, down-feed and up-feed.

Fig. 3 –
This shows a down-feed arrangement. The supply must be above the tube level of the convector. Air valves are not needed at the individual units. A proper piping system allows for the collection of air and venting at the high point.On all down-feed systems, the pitch should be down toward the return.

Fig. 4 –

This shows an up-feed arrangement which can be used with first floor units when mains are in the basement or where the upper floors are supplied by risers from lower floors. Up-feed systems require venting at each convector, and the pitch should be down toward the supply.An optional chamber with a remote air vent is available consisting of 3/4″ coupling, 3/4″ to 1/8″ reducing bushing and 6″ air assembly.
