With outstanding advantages of quality and performance, ZOZEN thermal oil heaters have established a good reputation in the international markets. Recently, ZOZEN YQW series thermal oil heaters gained favor of SOTRATECH in Mauritius. SOTRATECH is an energy company engaged in rational utilization and sustainable development of energy, and it is committed to providing users with systematic energy solutions. This time SOTRATECH undertook a major project of a local textile mill. An energy-efficient thermal oil heater has a direct impact on the quality of the whole project, which provides heat energy for dying, printing, drying and other product progresses in textile industry. Therefore, SOTRATECH was very careful in the selection of the thermal oil heater. SOTRATECH ultimately chose ZOZEN as its thermal oil heater supplier after a series of comparative studies. The director of SOTRATECH expressed that ZOZEN thermal oil heater featured advanced production technology and strict inspection, which fully ensured the quality and performance. After learning the actual condition of the project, ZOZEN provided SOTRATECH with a set of 2.8MW YQW series gas-fired thermal oil heater. The heat exchange surface of the thermal oil heater adopts multi-loop round coil tube structure, which features high security, sufficient heating surface and high thermal efficiency. The waste heat boiler, air pre-heater and economizer are installed on the tails of the thermal oil heater to effectively save energy and reduce consumption.
