Condensation in reservoirs
Hydraulic and lubricating oils must be kept free from contamination and water. Most fluid reservoirs need to be able to breathe, which allows water vapour and solid contaminants to enter. Temperature fluctuations in the reservoir cause this water vapour to condense which not only causes oxidation of the oil, but can also lead to considerable mechanical damage.

Filtration and drying: a single process
Standard air breathers remove some of the solid particles but allow water vapour in the air to pass freely. The RMF 'Air conditioner' deals effectively with both so reservoirs can breath clean, dry air. The air is first dried by passage through a column packed with   Z-R gel granules. The dried air is then passed through a pleated synthetic fibre filter element (replaceable spin-on type) where solid particles are removed, so that the air reaching the reservoir is both clean and dry.

Monitoring
The uptake of moisture can be observed by the change in colour of the indicator granules in the Z-R gel. They turn from ruby-red (active) to a light orange (replace) The Z-R gel granules are completely replaceable, non toxic and non carcinogenic. The operation of the air filter can be monitored by an optional 'filter minder'.

Active coal
RMF 'Air conditioners' can be fitted with a combination of Z-R gel and active coal. The active coal will eliminate oil vapour and the smell, it will also prevent the Z-R gel from being contaminated with this oil damp.

• Benefits RMF 'Air conditioner'
• Reducing water contamination level prolongs the life of the additive package and reduces oxidation of the oil and bearing surfaces
• Eliminates rusting due to condensation                  
• Reduces machine downtime
• Extends the machine's useful life
• Reduces cost of ownership

Applications
RMF 'Air conditioners' can be used on hydraulic power units, lube and oil tanks, gearboxes, diesel

fuel tanks, storage tanks for biodegradable fluids.

Industries that are successfully applying 'Air conditioners' include: steel industry, aviation industry, forestry industry, pulp & paper industry, cement industry and petrochemical industry.
