NYCODIEL 1244

With extra low pour point and low viscosity at low temperature, NYCODIEL^® 1244 might be used at temperatures as low as -30°C.

With high saturation limits, NYCODIEL^® 1244 can absorb large quantities of moisture without impacting breakdown voltage. It enables slower ageing of transformers, extension of cellulose insulation life, reduction of bubble evolution during overloads and of condensation during cool down.

NYCODIEL 1244 are fully compatible and miscible in all proportions with mineral oil, natural ester oils and other synthetic esters meeting the same specification but are not miscible with silicone oils. fluid is mineral oil, NYCO recommends that remaining content is less than 2%, to ensure keeping fire resistance properties (class K3).

As readily biodegradable products with non-hazardous classification, NYCODIEL^® 1244 has lower impact on the environment in case of leakage. Containment measures can be adapted accordingly. It meets European Ecolabel and Federal environment agency of Germany (UmweltBundes Amt.) requirements.

With extra low pour point and low viscosity at low temperature, NYCODIEL^® 1244 can be used in cold climates and over a wide range of temperature (from -45°C to +140°C).

With high saturation limits, NYCODIEL^® 1244 can absorb large quantities of moisture without impacting breakdown voltage. It enables slower ageing of transformers, extension of cellulose insulation life, reduction of bubble evolution during overloads and of condensation during cool down.

• Due to their structures, synthetic esters absorb water (water is not free but “inactive” since it links to ester molecules by hydrogen bonds and Van der Walls links). Synthetic esters can absorb a high level of water without loss of dielectric breakdown voltage.
• Allows for partial drying of insulating paper, leading to improvement of transformer lifetime without loss of power (very useful in retrofilling operation).

Retro-filling is a possible solution to extend transformer lifetime. Owing to its ability to entrap water molecules, NYCODIEL 1244 will even remove residual humidity from the insulating paper. NYCODIEL 1244 are fully compatible and miscible in all proportion with mineral oil, natural ester oils and other synthetic esters meeting the same specification but are not miscible with silicone oils. NYCODIEL® 1244 is a K Class fluid, exhibiting Fire Points above 300°C. In case of retro-filling, if the ‘former’ fluid is mineral oil, then a high percentage of residual mineral oil may impact the properties of the ‘new’ fluid, such as lowering of the Flash / Fire Points and the breakdown voltage. If former fluid is mineral oil, NYCO recommends that remaining content is less than 2%, to ensure keeping fire resistance properties (class K3).
