Detail Oli HTO ( Heat Trasfer Oil)
Description
PIKOLI is a high quality heat transfer medium made from solvent refined mineral oil. It gives
outstanding performance in indirect heating installations operating at bulk oil temperatures up to 315° C.
Benefits
PIKOLI offers the following benefits:
Highly resistant to thermal cracking and decomposition
Excellent thermal stability reduces viscosity increase
Low viscosity gives early start-up
Non toxic in the event of leakage
Good handling properties at low temperature
Minimum heat transfer interference due to deposit formation
Excellent thermal properties give improved operating efficiency
Long trouble free service life giving improved operating profit
Applications
PIKOLI is recommended for use in indirect heating and cooling installations in all kinds of industrial
processes operating at bulk oil temperatures up to 315° C.
The limitation of the upper temperature is based on the high temperature properties ofPIKOLI at
atmospheric pressure. If used above this level
vapour lock may result unless the system is designed to operate
at the higher temperature by
pressurising with an inert gas, such as nitrogen.
At higher temperatures fluid life will be shortened because the rate of thermal degradation increases markedly
as temperatures rise above the recommended limit. In
well designed systems the temperature of the oil film
surrounding the heating element will be about 15° C to 30° C above the bulk oil temperature. To ensure long
service life and freedom from deposition of sludge and coke-like material, which interferes with heat transfer
rates, the temperature of the oil film adjacent to the heater element should preferably not exceed 345° C.
Properties
The high thermal stabilitPIKOLI will reduce the tendency towards viscosity increase in correctly
designed indirect heating systems and
prevent formation of deposits which interfere with efficient heat transfer
operations. The viscosity has been selected to provide quick circulation at start-up and the Pour Point gives
good handling properties at low temperatures.
The density of the product gives good thermal properties, specific heat and thermal conductivity. These
features all help to reduce circulating pump power input and enable systems to be built with smaller bore
piping, thus contributing to lower initial installation costs and increased op
