Luhua Group, a well-known Chinese edible oil company, is a large enterprise with 24 production bases, mainly engaged in a number of industries such as edible oil, condiments and vegetable processing. The manager of the edible oil plant needed to purchase a thermal oil boiler to provide high-temperature steam for the complex production processes of drying/cooling - hot air baking and frying - suction cooling - grits rolling and crushing/skinning - steaming and frying in edible oil processing. The ZOZEN design team customized a 1.2 million kcal hot oil boiler system solution for the customer.

The YQW series thermal oil boiler system manufactured by ZOZEN adopts the injection type forced circulation system, which can realize low-pressure and high-temperature heating, and is also equipped with a waste heat recovery device, which improves the comprehensive heat efficiency through the waste heat recovery and utilization of high-temperature flue gas. After a period of use, ZOZEN heat-conducting oil boiler has stable operation, perfect safety devices, and very obvious energy-saving and high-efficiency features.

The customer was impressed with ZOZEN's extensive project experience and comprehensive service, and the boiler has significantly improved the efficiency of cooking oil production since its installation. The boiler has been running steadily for the past year without any problems. It is such outstanding product quality that Luhua Group purchased 11 sets of YQW series heat-conducting oil boilers directly from ZOZEN for other production bases.
