The unit is fit ted with an elec tronic steam bot tle hu midi fier suit able for use with wa ter of vary ing degrees of hard ness, pro vided that the wa ter is not treated or demineralized. The hu midi fier is com plete with a wa ter inlet valve, a wa ter outlet valve and a maximum wa ter level sensor.
The steam cyl in der is in stalled in the unit’s air tight com part ment to avoid heat losses. Steam from the cyl in der is mixed with the dis charge air from the evapo rat ing coil by means of a cop per steam dis tribu tor.
The unit con trol ler moni tors the con di tion of the steam cyl in der, and gen er ates an alarm when the cyl in der needs to be changed. Cyl in der re place ment is easy and quick.
The hu midi fier is com plete with a self- adapting flow con trol sys tem which moni tors wa ter con duc tiv ity and con trols the elec tri cal cur rent pass ing through the cyl in der. Out put ad just ment is from 30 - 100% via the unit con trol ler.

Re fer to the Op tional sec tion of the Tech ni cal Data Ta bles for hu midi fier ca paci ties, FLA’s, etc.
Dehumidification
On air- cooled mod els, the unit de hu midi fies the air by re duc ing the air flow across the coil (the fan is switched to a lower speed) and switch ing on the com pres sor.
In chilled wa ter mod els, the unit de hu midi fies by fully open ing the chilled wa ter valve.
In Dual Source units, the unit de hu midi fies us ing the "Cur rent" cool ing source. If the cur rent source is DX, the unit de hu midi fies the air by re duc ing the air flow across the coil (the fan is switched to a lower speed) and switch ing on the com pres sor. If the cur rent source is chilled wa ter, the unit de hu midi fies by fully open ing the chilled wa ter valve.
In Free cool ing units, the unit dis ables free cool ing on a call for de hu midi fi ca tion and de hu midi fies the air by re duc ing the air flow across the coil (the fan is switched to a lower speed) and switch ing on the com pres sor.
Packaging

Note: The suggested condenser selections/performances for each outdoor ambient are based on calculated data. The actual selection of a condenser should always be verified on the basis of the specific working conditions on each site.
Water cooled/freecooling units only
Plate heat exchanger
All wa ter cooled units (mod els W, H, F) are fit ted with a brazed plate heat ex chang ers made of stain less steel. This type of con denser is de signed for high ef fi ciency heat ex change. The con denser is in ten tion ally over sized for the ap pli ca tion to re duce pres sure drops (and the en ergy con sump tion of the cir culation pump) in the wa ter sup ply and thus al low the unit to op er ate with an ex ter nal wa ter cooler in a closed cir cuit at high out door tem pera tures. Pres sure re lief valves are fit ted down stream of the con denser. The valve is equipped with a threaded con nec tion to al low the re frig er ant to be dis charged out side of the con di tioned space.
Wa ter cooled units can op er ate with mains wa ter, cool ing tower wa ter or wa ter in a closed cir cuit with an ex ter nal dry cooler. Free cool ing units op er ate with wa ter in a closed cir cuit from an ex ter nal dry cooler only.
When op er at ing in a closed cir cuit, it may be nec es sary (de pend ing on out side tem pera tures) to add mono eth yl ene gly col to pre vent the wa ter freez ing in win ter , re fer to the unit In stal la tion Man ual for ap pli ca ble per cent ages.
A pump is used to cir cu late wa ter (wa ter/gly col) through the unit (it is not sup plied).
If mains wa ter or tower wa ter is used, it is rec om mended to fit a me chani cal fil ter on the wa ter line to pro tect the con denser against pos si ble im pu ri ties con tained in the wa ter (for con denser clean ing, re fer to the In stal la tion Man ual).
Drycooler
A dry cooler can be sup plied, if re quired. Full de tails of all dry cool ers are avail able in the Dry cooler Tech ni cal Data Man ual, P/N SLE DC TDM.
Head pressure control valve
Head pres sure op er ated regu lat ing valves ac cu rately con trol the con dens ing tem pera ture and sys tem ca pac ity for vari ous en ter ing fluid tem pera tures. A 2- way head pres sure con trol valve is fit ted as stan dard on wa ter/gly col cooled, dual source wa ter cooled and free cool ing units.
The valve con trols the con dens ing pres sure by regu lat ing the wa ter flow to the plate con denser. It is in stalled at the con denser out let with the pres sure probe po si tioned on the re frig er ant dis charge line. It is auto mati cally closed when the com pres sor is not op er at ing. It is sized for in let wa ter flow tem pera tures lower than 17 0C re sult ing in low water- side pres sure drops.
For higher wa ter in let tem pera tures, higher wa ter flowrates are re quired and pos si bly spe cial wa ter regu lat ing valves, con sult Lie bert Ap pli ca tions En gi neers for de tails.
Freecooling only
Freecooling coil
The Freecooling coil is lo cated on the re turn air side of the evapo ra tor coil. Wa ter/gly col flow to the coil is con trolled by a pre-piped 2- way modu lat ing motorised valve. When sup plied with a coolant so lu tion of suf fi ciently low tem pera ture, the coil is suf fi ciently sized to of fer an equal cool ing ca pac ity to that ob tained us ing the re frig era tion cir cuit. The coil is tested to 30 Bar.
2-way control valve
As the out door am bi ent drops to a suf fi ciently low tem pera ture, the 2- way mo tor ised valve modu lates the flow to the coil, as in a chilled wa ter sys tem. The valve in cludes an op er at ing link age and elec tric mo tor.

Hot gas reheat
Chal lenger Plus can be sup plied with a hot gas re heat coil if re quired. This type of re heat uses the heat which is nor mally re jected in the con denser to heat the air in the con di tioned space, thus sav ing en ergy. A con trol valve pre vents the re frig er ant from flow ing to the re heat ing coil when re heat is not re quired. The re heat coil is sin gle or dou ble row de pend ing on the model, and con structed of cop per tubes with alu mi num fins.
When hot gas re heat is re quested, it is sup plied in con junc tion with elec tri cal re heat in two stages as fol lows:

Influence of glycol concentration on the cooling capacity of Challenger Plus units
The presence of glycol mixed with water, as the thermal carrier fluid, reduces the cooling capaci ty of the unit. This capacity reduction differs depending on the glycol percentage and the return air temperature.
The average reductions for the Total Capacity and the Sensible Capacity are given in the following charts.
