Heaters PT-16/150 MG(Zh), PT-25/100 MG(Zh), PT-6.3/200 MG(Zh), PT-4-64Zh (K)

Designed for heating oil, petroleum gas or their mixtures in oil and gas gathering systems from wells to main pipelines as well as for heating water in various industries. Climatic performance - "U(moderate)" and "HL(cold)"

Automation

Possible to supply the heater with various control systems.

The oil heater is normally equipped with the control system SA-PPNbased on the Direct Logic DL-205 controller.

Control systems provide the ability to exchange information with the upper control level and remote control using various industrial protocols (MODBUS RTU, etc.), RS-232 and RS-485 interfaces which makes it easy to integrate the heater into the process control system.

On request 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.
