Wellhead heaters NUS 0.1 (ZhM), UN 0.2 МЗ (Zh)

The wellhead  heater with separation unit NUS-0.1 (ZhМ) and wellhead heater UN-0.2M3 (Zh) are designed for heating oil and oil emulsion at wellheads during  their transportation in gathering systems.

The heater can be designed for work with gas or liquid fuel as well as on combined fuel  (oil, mazut, diesel fuel, gas), in this case the index "Zh" is used in the designation.
