Heatra Series
PAL Heatra oils are premium quality mineral-based heat transfer fluids with excellent thermal and oxidation stability. The base oils used in Heatra Series have been put through special refining steps to improve many of their exceptional properties and to remove undesirable characteristics that might lead to sludge or gum build-up under heat. These heat transfer fluids have high boiling points and good thermal conductivity making them ideal for use in closed circulating systems having bulk oil temperatures of up to 320ºC. They may also be used in open systems if the bulk oil temperatures do not exceed 180ºC.
Peregrine Heatra heat transfer oils are recommended to be used in systems with forced circulation. Systems that depend on convection for circulation of the heat transfer medium do not provide a rapid enough flow to prevent local overheating and rapid deterioration of the oil.
Features
- High resistance to oxidation gives long oil service life.
- Low viscosity (especially Heatra 32) for efficient heat transfer
- Economical long life fluids
- Non-corrosive to brass, steel, stainless steel and aluminum heat transfer systems
- Good pumpability for ease of circulation
Applications
- Can be used in open and closed installations where the bulk oil temperature ranges are as outlined above, and where minimum shutdown temperatures are not below -7ºC.
- Closed, cold-oil sealed, indirect heating and cooling systems in all kinds of industrial processes operating at bulk oil temperatures up to the maximum temperatures quoted above and at atmospheric pressure.
- Open systems provided the bulk temperatures do not exceed the maximum temperatures quoted above.
- Typical applications include direct- and indirect-fired asphalt heaters, building heaters, plastic and wax coating
