Where a server room needs to be

Precision cooling handles the main hall, but monsoon air, leaky doors, UPS rooms and smaller edge sites often drift well above safe humidity.

Below 40%

Very dry air raises static-discharge risk. Most sites handle this with humidification.

40–60%

A common operating range for IT equipment. Your design spec sets the exact limits.

Above 60%

Condensation, corrosion on boards and contacts, and damp in cable and battery rooms.

What humidity does to IT infrastructure

Most humidity damage in a data centre is slow: corrosion and intermittent faults that are hard to trace back to the air.

Helps you stay within

  • ASHRAE thermal guidelines
  • Uptime and SLA commitments
  • OEM equipment warranties
  • Corrosion and intermittent faults

    Moist air corrodes connectors, boards and contacts, leading to faults that come and go and are hard to diagnose.

  • Condensation risk

    Warm, humid air meeting cold surfaces near cooling units and supply grilles can leave water where it should never be.

  • Edge and branch server rooms

    Smaller rooms without precision cooling sit at the mercy of the monsoon and of office AC that switches off at night.

  • UPS and battery rooms

    Damp air shortens the life of batteries, panels and switchgear in rooms that are often outside the main cooled hall.

  • Dust and humid air at doors

    Loading bays and entrances let in dust, heat and humid air every time they open.

  • Cooling that works harder

    Removing extra moisture through the cooling system uses energy that a dedicated dehumidifier can save.

Server rooms and edge sites

What goes wrong

Rooms without precision cooling go damp in the monsoon and when office AC is switched off.

What we fit

Portable dehumidifiers with a humidity setting hold the room steady day and night.

AWHD-50LWDE-621

UPS, battery and electrical rooms

What goes wrong

Batteries, panels and switchgear sit in rooms that are often outside the cooled hall.

What we fit

Portable or ceiling dehumidifiers keep these rooms dry without extra cooling.

WDE-621WDE-168C

New sites before go-live

What goes wrong

Concrete, screed and plaster in a new building release moisture for weeks.

What we fit

Industrial dehumidifiers dry the halls out faster, so racks go in on schedule.

WDE-150SWDE-190S

Spares and media stores

What goes wrong

Stored drives, tapes, spares and cabling absorb moisture between uses.

What we fit

A small portable dehumidifier keeps the store within a safe range.

AWHD-40L

Loading bays and goods-in

What goes wrong

Shutters open for deliveries let dust, heat and humid air straight into the building.

What we fit

An air curtain above the shutter keeps outside air out while equipment moves in and out.

EOHV MS

Entrances and security lobbies

What goes wrong

Main doors open all day as staff and visitors come through.

What we fit

A slim air curtain over the door cuts dust and conditioned-air loss.

Data centre humidity questions

Share your room sizes, cooling setup and the readings you're seeing, and our team will recommend the right equipment, free of charge.

What humidity should a server room be kept at?

Many operators aim for roughly 40% to 60% RH, and international thermal guidelines for IT equipment also set dew-point limits. Your design specification or equipment maker sets the exact range, and we size the dehumidifier to hold it.

We already have precision cooling. Why add a dehumidifier?

Precision units manage the main hall well. Dehumidifiers help where they don't reach: edge and branch server rooms, UPS and battery rooms, spares stores, and new buildings drying out before go-live.

Will a dehumidifier add heat to the room?

Yes, a refrigerant dehumidifier releases a small amount of heat as it works. In most rooms your cooling absorbs this easily, but we check it when sizing so the room stays within its temperature range.

Do we need someone to empty the water tank?

No. Most models we recommend for server rooms support continuous drainage to a nearby drain point, so they run unattended.

Do you supply and install outside Mumbai?

Yes, we deliver across India with free consultation and setup guidance. On-site installation and demos by our own team are available in Mumbai. Elsewhere, service and spares come through our network in 100+ locations.

Where do air curtains help in a data centre?

At loading bays, goods-in and busy entrances, where doors open often and let in dust, heat and humid air. We size the air curtain to your door width and height.

Seeing humidity alarms in your server rooms?

Send us your room sizes and current RH readings. We'll recommend dehumidifiers and door protection that fit around your existing cooling, free of charge.
