MA-R series

Adsorbers of the all-aluminum MA-R series are robust. They offer high resistance, are available with NBR, FKM or EPDM seals and are used on numerous systems and containers – for example, on 200l drums and 1000l IBCs. They protect isocyanates, polyols, DOT4, SKYDROL, solvents, oils and more from moisture ingress.

MA-R adsorbers are refillable. This makes the investment profitable after a short time. Desiccants and spare parts can be reordered at low cost and quickly replaced.

The use according to ATEX product directive 2014/34/EU in zone II 2 G / D IIC T4 is also possible. In the viewing window, the saturation of the desiccant is checked to see the status of the adsorber.

Structure and added value

1Sustainability:
Refillable version ensures favorable operating costs

2Self-regeneration:
Increase in utilization times through the use of activated carbon

Clean supply air due to integrated 3μm filter

4Desiccant:
Efficient desiccant with harmless color indicator from orange to green

5Sloshing protection:
Prevents oil droplets from entering the desiccant

6Robust housing:
Housing completely made of aluminum. Can be used according to ATEX 2014/34/EU, Zone II 2 G/D IIC T4

Method of operation

Adsorption – drying of the supply air

  • Level of the plant decreases
  • Humid air is sucked in
  • Air flows pressureless into adsorber
  • Uniform flow through the adsorber
  • Air is dried to 2%rH
  • Silica gel changes color
  • Air is filtered to 3μm

Dry and clean supply air

Desorption – Separation of oil particles

  • Level in the plant increases
  • Dry, oily air is squeezed out
  • Activated carbon absorbs oil mist
  • Dry, oil-free air regenerates the silica gel
  • Silica gel partially recolors

Self-regeneration and oil-free exhaust air

Technical Data

Flowchart

The sucked-in air flows into the adsorber almost without pressure and distributes the air evenly over the cross-section. The pre-filter disc frees the air from coarse dirt particles.

When the desiccant silica gel flows through, the water molecules are reliably removed from the air. The gap volume of the granulate is optimally selected with 2 to 5 mm grains and guarantees a minimum pressure build-up with simultaneous very good drying efficiency. Thus, at the beginning of the drying process, a residual air humidity of max. 2 % rH and a dew point of -40 °C are achieved. Due to the water absorption, the silica gel in the standard changes color from orange to green. A complete green coloration indicates the end of the product life cycle. The 3 µm filter ensures that all dirt particles are separated from the ambient air and the silica gel and that the connected equipment is not contaminated.

When the air flows out, the two-stage slosh protection prevents larger oil droplets from penetrating the desiccant. The activated carbon also adsorbs the finest oil particles, thus enabling the adsorber to regenerate itself.

Adsorbers of the MA-R series consist of aluminum, silica gel orange, an FKM or EPDM seal and can be used for the aeration of all common hydraulic and gear oils, lubricants, fuels as well as isocyanates. In addition, SKYDROL, brake fluids and solvents, for example, can be aerated with this series.

Spare part kits

Sustainability starts with using product components for as long as their life cycle allows and replacing only those components that show signs of wear. With our spare parts kits for the refillable adsorber series, we ensure that you can replace each individual component of an adsorber as needed.

For example, the desiccant in our adsorbers becomes loaded during use, increasingly loses its ability to adsorb moisture and needs to be replaced, but the adsorber housing is particularly durable. Our refillable adsorbers can therefore be easily opened and the desiccant replaced. Seals, particle filters & activated carbon discs, on the other hand, can withstand a few replacement cycles, depending on the load. However, we recommend replacing them after 4-5 replacement cycles at the latest to ensure smooth operation of the adsorbers.

Our spare parts kits include seals, particle filters, activated carbon discs and other components that match the respective adsorber series. The matching desiccants for the adsorbers are available separately and in different size classes.
