Munters - Dehumidification / Humidification / Cooling

Desiccant Rotor - PowerPurge™ - Adiabatic Humidification - Oasis™ - GLASdek

Munters Desiccant Rotor Technology

Munters desiccant dehumidifiers attract moisture from the air by creating an area of low vapour pressure at the surface of the desiccant. The pressure exerted by the water in the air is higher, so the water molecules move from the air to the desiccant and the air is dehumidified.

Munters desiccant dehumidifiers make use of changing vapour pressures to dry air continuously in a repeating cycle described by the simple diagram below.

As the desiccant picks up moisture from the surrounding air, dry air is discharged to the process area and the reactivation air stream discharges the wet air outside.

Munters units can operate in a wide range of temperatures, including at low temperatures down to -40°C.

Munters PowerPurge™ - Save up to 35% Energy

PowerPurge works in a similar way to the standard desiccant rotor, yet it has its own small fan that circulates the air between the two additional sectors. PowerPurge saves energy in two ways:

The unique patented PowerPurge acts as an energy recovery system, collecting waste heat off the hottest section of the desiccant wheel and using it to help with the regeneration by pre-heating the coolest part of the rotor. This reduces the energy required for reactivation while also reducing the discharge temperature of the process air, resulting in lower energy costs for post-cooling;

PowerPurge can also save on first cost. Equipping a desiccant system with PowerPurge can reduce the size of the desiccant rotor without diminishing the dehumidification capacity.

Benefits of Munters PowerPurge™:

  • Reduced reactivation energy
  • Reduced post cooling energy
  • Energy savings
  • Improved drying performance

Munters Adiabatic Humidification & Cooling

Water is circulated through a pump station and supplied to the top of the cooling pad via a distribution manifold. A distribution pad on the top of the cooling pad ensures an even water distribution. The water flows down the corrugated surface of the GLASdek evaporative cooling pad.

Part of the water is evaporated by the warm and dry air that passes through the pad. The heat that is needed for the evaporation is taken from the air itself. The air that leaves the pad is therefore cooled and humidified simultaneously without any external energy supply for the evaporation process. This is nature’s own cooling process.

Modular design fits all AHUs, for airflows from 0.5 to 30m³/s.

Munters Direct and Indirect Evaporative Cooling systems reject heat without adding moisture to hospitals, airports, correctional and power facilities. Munters award winning Oasis™ Indirect Evaporative Coolers can provide energy savings of more than 70% when compared to traditional chiller cooling systems.

Evaporative cooling is an energy efficient solution for industry, where hot indoor climates lead to low yields, reduced productivity and unsatisfied working staff.

EC Plug Fan Upgrades

Upgrading dehumidifiers and air handling units (AHU's) with EC Plug fan technology can realise significant savings. Benefits include:

  • Reduce energy consumption by up to 75%
  • Reduce running costs
  • Save on labour & maintenance
  • No more belts to change
  • Reduce CO2 – help meet targets
  • Improve speed control
  • Upgrading rather than replacing AHU’s saves time, money & resources

Munters offer a FREE, full survey report and data logging service. This ensures any proposals are based on actual power use, enabling Munters engineers to forecast expected savings. Munters unique modular frame and fan plate systems enable fast installation, reducing downtime.
