The HIDROSECUR D-46 applications cover the entire field of hydraulic installations that work near a heat source and that a mineral oil leak could spread fire. HIDROSECUR D-46 is highly biodegradable so small leaks do not create environmental pollution problems in soils, aquifers, etc. As an example, some applications are detailed below: - Hot rolling mills. - Continuous casting. - Bullion conveyors. - Die casting of metals. - Forging, stamping and sintering presses. - Heat treatment furnaces. - Welding machines. - Forestry machinery. No special measures are required for handling this product. HIDROSECUR D-46 is compatible with most of the rubbers that make up the gaskets and seals of the circuits that work with mineral oil. Natural rubbers and polyurethane are not advisable. To use the HIDROSECUR D-46 in a circuit that has previously worked with mineral-type hydraulic oil, it is enough to proceed as follows: 1. Empty the oil circuit and clean the tank, making sure that it is not painted inside. 2. Remove the filters from the circuit. 3. Fill the tank with HIDROSECUR D-46 to the minimum level for the circuit to work. 4. Start the circuit by operating at low pressure, activating all movements, for 1 to 2 hours. 5. Empty the HIDROSECUR D-46, put the filters, fill the tank with new HIDROSECUR D-46 and work under normal conditions. 6. If a high degree of dirt is observed during the emptying of the previous point, repeat points 3, 4 and 5.
