High-Quality Thermal Oil Heaters from ZOZEN
ZOZEN, as one of the most trusted thermal oil heater suppliers, offer a diverse range of thermal oil heater products which can be divided into three series: YQW series gas/oil-fired horizontal thermal oil heaters, YQL series gas/oil-fired vertical thermal oil heaters, and YLW series coal/biomass-fired horizontal thermal oil heaters. These heaters operate with a working pressure of 0.8 – 1 MPa and a working temperature of up to 320°C. They offer broad fuel adaptability and can achieve high temperatures with low pressure, minimizing heat loss to only radiation and transportation losses.

YQW Series Gas/Oil-Fired Horizontal Thermal Oil Heaters
Capacity Range: 1400 – 14000 KW
Applicable Fuel: Natural gas, coke oven gas, biogas, heavy oil, diesel, light oil, etc.
Design Features:

  • Multi-layer densely packed tube bundles and multiple sealing steel rings prevent flue gas bypass.
  • The inner coil absorbs more heat than the middle and outer coils, so it is designed with a larger flow rate for safer and more reliable operation at high temperatures.
  • Pre-paint sandblasting, high-quality paint, and automotive painting techniques ensure a four-layer paint finish and one layer of varnish, making the boiler aesthetically pleasing and resistant to sea water corrosion during transport. This YQW series has made ZOZEN a wise choice among all thermal oil heater suppliers.

YQL Series Gas/Oil-Fired Vertical Thermal Oil Heaters
Capacity Range: 7000 – 29000 KW
Applicable Fuel: Natural gas, coke oven gas, biogas, heavy oil, diesel, light oil, etc.
Design Features:

  • Different refractory and insulation structures are used for different temperature zones; high-quality refractory insulation materials are used inside, and stainless steel protective plates are used outside to minimize heat loss.
  • The rear of the boiler is equipped with various energy-saving devices such as waste heat boilers, economizers, and air preheaters, which can be combined based on customer needs and process conditions to fully utilize waste heat, reducing exhaust gas temperature to ≤90°C.
  • The three-pass coil structure ensures strong safety and ample heating surface. This YQL series has made ZOZEN a wise choice among all thermal oil heater suppliers.

YLW Series Coal/Biomass-Fired Horizontal Thermal Oil Heaters
Capacity Range: 1400 – 29000 KW
Applicable Fuel: Bituminous coal, anthracite, biomass pellets
Design Features:

  • With a service life of up to 20 years, following the operation manual ensures the boiler’s longevity.
  • The boiler features protections for oil temperature, flue gas temperature, liquid level, flow rate, and pressure differential, enhancing safety.
  • Optimized convection heating surfaces and effective fixing and support structures extend the boiler’s service life. This YLW series has made ZOZEN a wise choice among all thermal oil heater suppliers.

ZOZEN’s Collaboration with the Oilfield Industry
A Qingdao-based energy technology company has embarked on an in-depth cooperation with Kazakhstan on environmental technology in oilfields. ZOZEN, as one of the most reliable solution among all thermal oil heater suppliers, provided stable and efficient thermal oil heaters for this project. The first batch of YQW series thermal oil heaters and WNS series gas-fired steam boilers has been shipped to Kazakhstan, marking another successful endorsement of ZOZEN in Kazakhstan. The automated CNC coil production line ensures that the coils are formed in one go, eliminating the need for reshaping and extending the lifespan of the thermal oil heaters. ZOZEN not only boasts advanced manufacturing processes but has also developed various waste heat recovery devices. By utilizing high-temperature flue gases, these devices reduce heat energy loss, increasing the overall thermal efficiency of the organic heat carrier boilers to over 95%.

In conclusion, ZOZEN stands out as one of the most trust-worthy thermal oil heater suppliers with its high-quality products.
