Accessory

Description

External condensate cooling

Self-actuated and electric condensate waste water coolers are used to reduce waste water

temperatures to below 140 °F (60 °C) before it is discharged into drains.

Steam distributor

Steam distributors are used for adding steam into ventilation ducts. They are available in

three different steam capacities and various lengths to suit duct dimensions.

Refer to Steam Distributor Installation Manual (Condair document 2556592) for additional

details and part numbers.

SAM-e and Mini SAM-e

distribution manifolds

The SAM-e distribution manifolds are used for adding steam into ventilation ducts larger than

24 in (6 cm) where either higher steam capacity or short absorption distance is required. The

Mini SAM-e is available in dimensions under 24 in (61 cm). They are available in a range of

sizes and steam capacities to match duct and humidifier requirements.

Refer to SAM-e Engineering Manual (Condair document 1503529) for additional details and

part numbers.

Remote blower pack

Blower packs are used for direct humidification of the conditioned environment. Blower

packs are capable of distributing up to 100 lb/h (45 kg/h), should be selected to match or

exceed humidifier capacity.

Refer to Blower Pack Installation, Operation and Maintenance Manual (Condair document

2582277) for additional details.

On/Off humidistats

Condair offers a range of digital and mechanical On/Off duct and wall-mounted humidistats

for use with control and high limit applications. Refer to

Table 7 on page 11

Modulating humidistats

Condair offers a range of digital modulating duct and wall-mounted humidistats for use with

control and high limit applications. Refer to

Table 7 on page 11

Outdoor temperature sensors Provides automatic humidistat setpoint reduction to prevent condensation on windows/sur-

faces adjacent to outdoor air. Refer to

"Outdoor Temperature Setback" on page 44

for additional

details.

2520263 – Duct-mounted temperature sensor

2553858 – Outdoor mounted temperature sensor

Humidity transducers

Condair offers a range of digital humidity sensors for duct and wall-mounting for use with

control and high limit applications. Refer to

Table 7 on page 11

Air proving switch

Provides a mechanical differential pressure switch to enable humidifier operation when

there is airflow through the ventilation ducts. Adjustable for pressures 0.05-12 in H2O (0.01-

2.99 kPa). Refer to

"Air Proving Switch" on page 43

for additional details.

Steam line reducers

Provides a means of adapting steam line diameters to match the diameter of the steam

distributor.

1507846 – Steam line reducer (1-3/4 in to 7/8 in) copper

1508165 – Steam line reducer (1-3/4 in to 7/8 in) stainless steel

Condair flexible steam and

condensate hose

Steam hoses can be used as steam distribution lines or as couplers between copper or

stainless steel steam distribution lines. When used for steam distribution the maximum rec-

ommended hose length is 10 ft (3 m). Steam hose is available in two sizes.

Condensate hose can be used for draining condensate, or coupling to copper or stainless

steel condensate lines.

1328810 – Steam hose (7/8 in I.D.) per foot (30 cm)

1328820 – Steam hose (1-3/4 in I.D.) per foot (30 cm)

1328840 – Condensate hose (3/8 in I.D.) per foot (30 cm)

Large/small condensate trap

tee

Condensate trap tee must be used to remove condensate that forms in steam distribution

lines. Condair offers tees to match large and small steam lines. Offered in Copper only.

1329634 – Condensate trap tee – small (7/8 × 7/8 × 3/8 in)

1329635 – Condensate trap tee – large (1-3/4 × 1-3/4 × 3/8 in)

In-line water filter and re-

placement filter elements

In-line water filter to remove sediments in the supply water that can obstruct the fill valve

strainer or drain fittings.

1329505 – In-line water filter (5 micron)

1329561 – Replacement filter cartridge (1 micron)

1329506 – Replacement filter cartridge (5 micron)
