Function: The distillation column uses a fluid as the heat transfer medium, providing indirect, uniform, and precise heating through a closed-loop circulation system, which partially vaporizes the materials inside the column, thereby achieving efficient separation.

Common Applications: Petroleum & chemical, new energy & advanced materials, textile & chemical fiber, oils & fats / food, building materials & road construction, plastics & rubber, wood & paper, pharmaceuticals & fine chemicals, etc.

Function: Fractionating Column uses a fluid heat transfer medium to separate close-boiling mixtures via repeated vapor-liquid contact, achieving multi-stage distillation: low-boilers at top, high-boilers at bottom.

Common Applications: Petroleum & chemical, new energy & advanced materials, textile & chemical fiber, oils & fats / food, building materials & road construction, plastics & rubber, wood & paper, pharmaceuticals & fine chemicals, etc.

Function: Thermal oil heater rapidly heats oil in a closed-loop system and circulates it to downstream equipment (e.g., reactors, calenders, ovens), providing stable, precise indirect heat with automatic temperature control for energy efficiency.

Common Applications: Petroleum & chemical, new energy & advanced materials, textile & chemical fiber, oils & fats / food, building materials & road construction, plastics & rubber, wood & paper, pharmaceuticals & fine chemicals, etc.

Function: Heat exchange is achieved through a jacket or coil using thermal fluid, ensuring uniform and stable temperature distribution within the reactor vessel.

Common Applications: Biopharmaceuticals, pesticide synthesis, scientific research, chemical processing, etc.

Function: Asphalt heater uses high-temperature thermal oil for uniform, precise heating to melt solid asphalt into liquid (pumping/construction), control prevents aging/coking, supports tank heating and pipe tracing at atmospheric pressure.

Common Applications: Road construction and maintenance, building waterproofing engineering, ports and large-scale storage and transportation bases, etc.

Function: Using a closed-loop system, it precisely heats/cools thermal oil to ±0.1–1°C, delivers it to mold/equipment channels, stabilizing mold temperature, improving product quality and efficiency.

Common Applications: Petroleum & chemical, new energy & advanced materials, textile & chemical fiber, oils & fats / food, building materials & road construction, plastics & rubber, wood & paper, pharmaceuticals & fine chemicals, etc.

Function: Through a closed-loop system, thermal oil is precisely heated and uniformly delivered to calender rolls, maintaining constant roll surface temperature to ensure even plasticization and thickness control of materials (e.g., plastic, rubber) as they pass through the nip, preventing defects from temperature variations.

Common Applications: Plastic calendering, rubber calendering, nonwoven and textile coating, paper and metal foil processing, etc.

Function: Through a closed-loop system, thermal oil uniformly heats the mixing chamber's jacket/rotor, providing precise temperature control. This ensures rubber mixing at constant temperature, prevents local overheating (scorch/vulcanization), and improves compound uniformity and quality stability.

Common Applications: Petroleum & chemical, new energy & advanced materials, textile & chemical fiber, oils & fats / food, building materials & road construction, plastics & rubber, wood & paper, pharmaceuticals & fine chemicals, etc.

Function: Through a closed-loop system, heated thermal oil circulates uniformly through the tenter's chambers or rollers, setting fabric at constant high temperature to relieve stress, stabilize dimensions, improve hand feel, and prevent color variation or distortion from uneven heating.

Common Applications: Petroleum & chemical, new energy & advanced materials, textile & chemical fiber, oils & fats / food, building materials & road construction, plastics & rubber, wood & paper, pharmaceuticals & fine chemicals, etc.
