Description
Ultratherm LT Heat Transfer Fluid | Recommended for USA Lab Chillers
Ultratherm LT is engineered for long-term operation in heat transfer applications that demand precise temperature control from -84°C (-120°F) up to 177°C (350°F). Recommended for USA Lab chillers, this versatile fluid is ideal for near-cryogenic applications and a wide range of heating and cooling processes.
Its economical cost, stable performance, and broad operating range make Ultratherm LT well-suited for the food processing, pharmaceutical, chemical, and botanical extraction industries. With extreme low-temperature capability and non-corrosive characteristics, it supports consistent system performance over extended service life.
Ultratherm LT also offers trouble-free operation with no need to monitor concentration or additive levels, making it a practical choice for demanding recirculating chiller and secondary cooling loop applications. Ultratherm LT is plant and user friendly with low odor, a high flash point, and no SARA reportable substances.
After its service life, Ultratherm LT can typically be disposed of through local waste oil recycling programs. Always check local regulations.
