by qualied personnel authorised by the manufacturer.
It is assumed that all persons working with the Condair EL are familiar and comply with the appropriate
regulations on work safety and the prevention of accidents.
Intended use
The Condair EL steam humidier is intended exclusively for air humidication via a steam distributor
or blower pack approved by Condair within specied operating conditions (see Condair EL operation
manual). Any other type of application, without the written consent of Condair, is considered as not
conforming with the intended purpose and may lead to dangerous operation and will void any warranty.
Operation of the equipment in the intended manner requires that all the information contained in this

3 Product Overview
3.1 Calculatingthemaximumrequiredsteamcapacity
The maximum required steam capacity must be calculated based on one of the following formulas:
mD: maximum steam demand in kg/h
V: volume of supply air portion per hour in m3/h (for indirect room humidication) or room volume to
be humidied per hour in m3/h (for direct room humidication)
ρ: specic gravity of air in kg/m3
ε: specic volume of air in m3/kg
x2: desired absolute room air humidity in g/kg
x1: minimum absolute supply air humidity in g/kg
The values for ρ,ε,x2and x1 can be gathered from the h,x-diagram or the Carrier-Diagram for moist
air respectively.

10 Product Overview
3.2 Models overview
