TM-RV 5M

The high quality adsorber TM-RV 5M is completely made of A4 stainless steel. With a separate valve part the maintenance interval is considerably extended. With 2,5 kg desiccant, even large transformers in offshore use can be efficiently ventilated.

The use according to ATEX product directive 2014/34/EU in zone II 2 G / D IIC T4 is possible as well as according to the corrosiveness category C5-M. On transformers, the valves protect the desiccant as well as the oils and lubricants from contamination and damage caused by water during swell and rain.

Product Description

The high quality adsorber TM-RV 5M is completely made of A4 stainless steel. With a separate valve part the maintenance interval is considerably extended. With 2,5 kg desiccant, even large transformers in offshore use can be efficiently ventilated.

The use according to ATEX product directive 2014/34/EU in zone II 2 G / D IIC T4 is possible as well as according to the corrosiveness category C5-M. On transformers, the valves protect the desiccant as well as the oils and lubricants from contamination and damage caused by water during swell and rain.

The adsorbers TM-RV are available with all standard connections for transformers. Due to the optimized design, these adsorbers can be maintained very quickly and cost-effectively. The wearing parts or the pure desiccant are quickly inserted and the protection of the plant to be ventilated is restored.

This product is also available in a food compliant manner – please contact us for further information.

Method of operation

Adsorber – supply air filtration

  • Level in transformer decreases
  • Humid air is sucked in
  • Valves open at 5 mbar
  • Uniform flow
  • Air is dried up to 2%rH
  • Silicagel changes color
  • Air is filtered up to 2μm

Dry and clean supply air

Desorption – Separation oil particles

  • Level in transformer increases
  • Dry, oily air is squeezed out
  • Activated carbon absorbs all oil particles
  • Dry, oil-free air regenerates silica gel

Self regeneration and oil-free exhaust air

Technical Data

Flowchart

The sucked-in air opens the valves in the lower part of the adsorber already at approx. 5 mbar. After flowing into the adsorber, the air is distributed evenly over the cross-section. A pre-filter disc removes coarse dirt particles from the air.

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 turns from orange to green. A complete green coloration indicates the end of the product life cycle. A 2 µm filter pad ensures that all dirt particles are separated from the ambient air and the silica gel and that the connected transformer is not contaminated.

In the case of outgoing air, the activated carbon prevents contamination of the silica gel and thus blocks the water-absorbing pores, allowing the adsorber to self-regenerate.

These adsorbers are made of stainless steel A4, silica gel orange, FKM sealings and can be used with all types of DIN connections for the ventilation of transformers.
