Condair humidifiers are used in datacenters around the world to providehumidity control, prevent electrostaticdischarge (ESD) or offer high capacity,low cost evaporative cooling.

Some of the World’s largest brands puttheir trust in Condair humidificationsystems to help them fulfil their datacenters’ environmental controlstrategies.

TRUSTED TECHNOLOGY

Condair has manufacturing facilities inCanada, UK, Denmark, Germany,Switzerland and China as well aswholly-owned sales operations in 13 countries and distributors in over 40 more.

The company has been serving theglobal data center industry for morethan 25 years. It has a dedicated Data

Center Business Development Team that draws expertise from all corners of the organisation, benefiting clients no matter where they or their projects are located.

Regional R&D departments work withproject teams to develop bespokesolutions, while specialist Condairservice engineering teams provide the

comprehensive maintenance supportcritical environments require.

Condair’s experience across manymajor global data center projects isbrought to bear from initial conceptdiscussions through to installation,commissioning and beyond.

HUMIDIFICATIONMaintaining ASHRAE standards & combating ESD

Humidity control in data centers isrequired to prevent ESD fromdamaging electrical equipment.

For existing data centers ASHRAErecommends a humidity level of 5.5°Cdew point to 60%RH and an allowablerange of between 20-80%RH (see fig 1).

Condair has a comprehensive range of humidifiers to help data centeroperators meet ASHRAE’s standards,including innovative low energyadiabatic systems that can utilise heatfrom the data halls to minimisehumidifier energy consumption.

A single Condair adiabatic humidifiercan deliver up to 630kW of evaporativecooling while operating on less than0.3kW of electricity. This technologyincreases the cooling capacity of a datacenter’s ventilation system and extendsthe use of free air cooling into periodswhen the outside air alone is too warmto meet the required internal conditions.

Condair humidifiers are used to deliver low energy evaporative coolingdirectly to incoming fresh air as well asbeing incorporated into in-directevaporative cooling systems. Thesereduce the temperature of incoming airwithout raising its humidity byhumidifying exhaust air andtransferring its resultant cool thermal

energy into the incoming air via a heatrecovery system.

These low energy cooling techniquescan significantly reduce or eveneliminate the need for mechanicalcooling in data centers with a resultantdrop in PUE.
