      High flash point of greater than 410°F (210°C) as measured by Pensky-Martens Closed Cup method (ASTM D93), petroleum based, non-toxic for use up to 600°F (315°C).
    • XCELTHERM® DCT
      A high performing, low cost hot oil heat transfer fluid formulated for the die casting and injection molding industries. Xceltherm® DCT has excellent heat transfer efficiency and an extended operational life due to its inherent thermal stability. For use up to 600°F (315°C).

Asphalt Industry Heat Transfer Fluids

    • XCELTHERM® ASP
      Superior resistance to heat stress for long life with the economy needed to keep plant operations profitable. Highly efficient, it moves heat at an economic operating cost, too. We developed this fluid for the Asphalt Industry to be consistent with environmental leadership by being non-toxic, aromatic free, more efficient and higher performing. All aspects of XCELTHERM® manufacturing and packaging processes are controlled by a stringent ISO 9001 quality program. Backed by a high degree of technical support and service, our heat transfer fluids are at the forefront of the latest thermal fluid technologies.
    • XCELTHERM® LT
      A highly compatible flush fluid to cleanly wash out used and degraded fluid from moderately sludged or viscous systems. For full system flush, can be run for a week or more just as heat transfer fluid before draining.
    • XCELTHERM® FF
      An aromatic solvent-based Flushing fluid for wash out of moderately sludged or viscous systems. Designed for and highly compatible with most other synthetic aromatic based heat transfer fluids including Dowtherm A but with maximum operation design up to 650 F/ 345 C. Fluid is designed for full system flush and production can be run for a week or more before draining.
    • XCELTHERM® CLX Cleaner
      One step non-hazardous cleaning agent for systems with fouling and other degradation issues. Restores heat transfer and removes degradation material while running production. Add 15% of the system volume and run for up to two weeks at up to 550°F for removing carbon and sludge.
    • XCELTHERM® TLX Cleaner
      “Super” cleaning agent for systems with that require removal of heavily degraded fluid that has caused excessive carbon and sludge. This low temperature cleaning leaves the system with a bare metal finish on internal piping in only one day. Drain, flush and refill the system to return it to full efficiency.
