Shell Heat Transfer Oil S4 X
High Performance Synthetic Heat Transfer Fluid
Deskripsi Produk
Shell Heat Transfer Oil S4 X adalah oli transfer panas sintetis yang dirancang untuk performa tinggi dan masa pakai lama pada sistem tertutup (indirect closed heat transfer).
Performance, Features & Benefits
-
Extended maintenance intervals → Mengandung antioksidan untuk mencegah oil cracking, oksidasi, dan penebalan.
-
Enhanced System Efficiency → Indeks viskositas tinggi → aliran & transfer panas optimal pada rentang suhu luas.
-
Low Vapour Pressure → Mengurangi risiko cracking & pembentukan produk dekomposisi volatil.
Main Applications
