A Small Dryer Fault Can Affect Your Entire Air System

An air dryer removes the moisture that compressed air carries from the compressor. When it stops working well, water travels into your pipes, valves, cylinders and tools. The result is rust, sticking valves, failed seals, spoiled products and unplanned stoppages.
We repair and maintain industrial air dryers so they hold the dryness your process needs. Our work covers fault finding, repair, planned servicing and performance checks, with the aim of finding small faults before they turn into a breakdown.

What a well-kept dryer gives you

  • Dry air at your machines, day after day
  • Fewer valve, seal and tool failures
  • Protection for your products and finishes
  • Lower repair bills and fewer surprises

Types of Air Dryers We Service

Refrigerated dryer

Cools the air so moisture condenses and is drained out

Typical Use

General plant air, workshops, light industry

Desiccant dryer (heatless)

Passes air through desiccant beads that absorb moisture, with towers switching over

Typical Use

Very dry air for paint, pharma, instruments

Desiccant dryer (heated)

Uses heat to regenerate the desiccant, saving purge air

Typical Use

Larger plants needing very dry air

Blower purge desiccant dryer

Uses a blower and heater to regenerate the desiccant

Typical Use

Large systems and high flow rates

Heat of compression dryer

Uses the heat of the compressor to regenerate the desiccant

Typical Use

Large oil-free compressor installations

Membrane dryer

Passes air over a membrane that removes moisture vapour, with no moving parts

Typical Use

Point-of-use drying and small, low-flow needs

Warning Signs Your Air Dryer Needs Attention

01

  • Water in air lines: the dryer isn't removing enough moisture and drops or tools show water.

02

  • High dew point alarm: the dryer cannot reach its rated dryness.

03

  • Overheating or high-temperature trips: blocked condenser, high ambient heat or a failing fan.

04

  • Icing or freezing: the cooling circuit freezes up and blocks air flow.

05

  • Desiccant saturated or dusting: beads have absorbed too much moisture or broken down.

06

  • Drain failures: drains stuck closed or open, flooding the dryer or wasting air.

07

  • High pressure drop: a clogged filter or internal blockage cutting flow to the plant.

08

  • Valve or switching faults: twin-tower valves stuck, so a tower stays wet.

01

  • Dust on the condenser: it cuts cooling and forces the dryer to work harder.

02

  • Neglected drains and filters: small blockages add up to big losses.

03

  • Hot, dirty plant rooms: heat and dust shorten the life of dryer parts.

04

  • Oil carry-over: oil from the compressor coats desiccant and heat exchangers.

05

  • Running past its capacity: added machines can push air flow beyond what the dryer can handle.

06

  • Skipped servicing: wear is found only when the dryer fails.

How We Bring Your Dryer Back to Full Performance

Fault diagnosis

We test the dryer, find the real cause and don't swap parts by guesswork.

Repair and part renewal

We repair faults and renew worn parts such as drains, valves, fans and filters.

Condenser and heat exchanger cleaning

We restore cooling performance and lower running load.

Desiccant care

We check and recharge desiccant in twin-tower dryers.

Refrigeration circuit service

We check refrigerant, controls and compressor, using qualified technicians.

Controls and valve repair

We set and repair the switching, timers and controls that run the dryer.

Dew point and pressure drop checks

Ee measure performance before and after service.

Planned maintenance visits

Regular servicing set to your dryer's hours and conditions.

What sets Kewat Flow Control apart

We are also a compressed air piping contractor, so we look beyond the dryer itself. If wet air comes from a drain point, an undersized line or a failing filter elsewhere in the system, we find that too, and we can correct it. You get one team that fixes the dryer and the cause of the moisture.

Frequently Asked Questions

Can you repair an air dryer that is causing moisture in the compressed air line?
Yes. We inspect the dryer, drains, filters and other connected components to identify the cause of moisture carryover. For industries requiring air dryer repair in Mumbai, we first identify the fault and then recommend the required repair or component replacement.
Do you repair both refrigerated and desiccant air dryers?
Yes. We service different types of industrial air dryers, including refrigerated and desiccant models. Our air dryer repair in Mumbai service is based on the dryer type, operating condition and issue identified during inspection.
Can you repair an air dryer that keeps shutting down or showing alarms?
Yes. We check the controls, temperature, pressure, condenser, fans, valves and other relevant components to identify the cause of repeated shutdowns or alarms. If you need air dryer repair in Mumbai, we can inspect the unit and recommend the required corrective work.
Can you service an existing air dryer without replacing the complete unit?
Yes. We first check whether the existing dryer can be repaired before recommending a replacement. Our air dryer repair in Mumbai service can include inspection, cleaning, faulty component replacement, testing and routine maintenance.
Can you check the compressed air system if the dryer is working but moisture is still reaching the machines?
Yes. Moisture can also result from issues with drains, filters, piping or other parts of the compressed air system. When handling air dryer repair in Mumbai, we can assess the connected system to identify whether the problem is with the dryer or another part of the air network.
