COMBINED HEATING OIL HEATER PNK-1.9

27-1.jpg

 PNK-1.9 general layout.

GENERAL DATA

Combined oil heater (further PNK-1.9) applied for heating oil of various viscosity and oil emulsion in oil processing and transportation systems.

features

Heating temperature can reach up to 110° С, therefore the heater can be used in heavy oil processing as well as in technologies of oil and gas condensate stabilization. 

Climatic modification – U, HL by GOST 15150-69.

Placement category –1 by GOST 15150-69.
