Concentration Control
To achieve optimum performance, freedom from
micro-organisms and corrosion it is essential that
coolants are maintained at the recommended
concentration. The concentration can be
monitored on a day to day basis using a
refractometer and the Fluid Concentration Chart.
More accurate values can be obtained using
laboratory titration methods. Your Houghton
Representative can advise on overall fluid control
within our comprehensive Fluid Management
System.
Mixing
Use coolant mixing valves where possible. W hen
mixing by hand slowly add concentrate to water
whilst stirring vigorously. Coolants should not be
mixed in the machine sump. Avoid using chilled
water.
Top Up
Coolant concentration may increase in use due to
water evaporation. To maintain the
recommended concentration, top up should be
made with a more dilute concentration and not by
water alone.
W ater Quality
Coolant performance can be affected by extremes of water
quality. Hard water (in excess of 300 ppm CaCO3) and high
levels of chlorides and sulphates can reduce the stability of
emulsions and reduce corrosion protection. Your Houghton
Representative can advise on local water quality.
Contamination
Where possible avoid contamination from foreign matter and
other fluids. Remove swarf and tramp oil from the machine
sumps frequently.
Disposal
Discarded metal working coolants may be removed by a
competent waste contractor. Alternatively, the product may
be treated by conventional oil separation and effluent
disposal methods. Specific advice is available on request.
Product concentrate or diluted fluid should not be introduced
into waterways. It is advisable to consult the Local Water
Authority regarding disposal.
Storage
Metal working coolants should be stored indoors in clean, dry
conditions. Protect from frost. Recommended storage
temperature is between 5ºC and 35ºC. If temporarily stored
outdoors, do not place drums upright. Tops should be
replaced on all containers when not in use.
