产品说明
KATMOTO HEAT TRANSFER OIL is a high-stability heat transfer (thermal) oil to L-QB, based on ISO VG 32 fluidity, for closed indirect heating systems. Its highly refined, thermally stable formulation provides efficient heat transfer with excellent resistance to thermal cracking, oxidation and coking, low vapour pressure and high flash and autoignition temperatures for safe, reliable and long-life operation in thermal-fluid circulation systems.
主要性能特点
| High thermal stability
resists thermal cracking and coking at high bulk operating temperatures. |
Efficient heat transfer
low viscosity and good thermal conductivity for fast, even heat transfer. |
| 耐氧化性
resists oxidation and sludge for long fluid life in closed systems. |
High flash & autoignition
high flash and autoignition temperatures for safe operation. |
| Low deposit formation
minimises coke and deposits on heater surfaces. |
Long fluid life
stable performance reduces fluid replacement and maintenance. |
应用和性能水平
| 应用 | Closed, indirect heat-transfer (thermal oil) systems in process heating, with forced circulation and bulk temperatures up to about 320°C, requiring an L-QB thermal oil. |
| 规格 | L-QB (thermal oil) — heat-transfer oil classification for closed indirect heating. DIN 51522 (Q) — heat-transfer fluid standard. High thermal stability — resists cracking and coking at high bulk temperatures. High flash / autoignition — safe high-temperature operation. Forced-circulation systems — suitable for closed forced-circulation thermal systems. |
| OEM适用性 | Closed thermal-oil heating systems operating up to about 320°C bulk temperature requiring an L-QB heat-transfer oil. Follow the heater/system manufacturer’s maximum film and bulk temperature limits. |
| 重要通知 | Observe the system’s maximum bulk and film temperature limits and ensure proper circulation. ”Suitable for” does not mean official approval unless separately certified. |
