Munters ML420 Munters industrial dryer

ML420 is a desiccant dehumidifier. Unlike conventional devices that work with a compressor and refrigerant gas, this device uses a silica gel rotor.

Steps of work:

The main advantage of this technology is that it maintains its performance even at low temperatures and very low humidity.

Why is the ML420 expensive?

Most dehumidifiers on the market have a price of 1000 to 3000 euros and are compressor type.

But the ML420 usually trades for between €12,000 and €18,000 new, and depending on options, switchboard, RH controller and country of supply, it may even reach over €20,000.

The reason for the high price:

✅ industrial silica gel rotor made in Sweden

✅ 24-hour continuous operation in an industrial environment

✅ Ability to produce very dry air

✅ Performance in sub-zero temperature

✅ anti-corrosion body and parts

✅ Very high lifespan (usually more than 15 years)

✅ Accurate humidity control for sensitive industries

Supply in Iran

For supply, technical advice, capacity selection and implementation of industrial humidity control systems, the critical industrial group can be introduced as a supplier and consultant for industrial dehumidification projects.

In one sentence, ML420 should not be compared with building or household dehumidifiers; This device is actually a process equipment (Process Dehumidifier) ​​for sensitive industries and its value is in the ability to produce very dry and stable air in conditions that normal devices are practically unable to do.
