A packaging company in Thailand is a professional manufacturer of heat shrink films, who is focusing on the production and innovative development of heat shrink films. The company's main products include PETG, PVC heat shrink film, and polyester for PETG heat shrink film. Polyester PET heat shrink film is a new type of heat shrink packaging material. Due to its characteristics of easy recycling, non-toxic, odorless, and good mechanical performance, it particularly meets environmental protection requirements of many countries and regions. PET film is internationally recognized as an environmentally friendly heat shrink film material. The production processes of PET film have such as blow molding, drying, thermal shrinkage, and maturation. The temperature of the thermal shrinkage process is high. So it can achieve higher temperatures compared to steam boilers by  using the thermal oil boiler for heating. Therefore, zhongde Boiler recommended a 1000kw YY (Q) W series oil gas fired thermal oil heater to the customer based on the production process of their company. And the customer ultimately chose heavy oil as the boiler fuel.

The YY (Q) W series oil gas fired thermal oil heater from zhongde Boiler adopts a three passes disc structure with a conical coil at the end, which can effectively protect the furnace wall at the end of the boiler. The inner coil has a larger flow rate that makes it much safer and more reliable during high-temperature running. What’s more, this thermal oil boiler from zhongde Boiler uses high-quality insulation materials on the inside of the furnace body and stainless steel plates on the outside, which greatly reduces heat loss. At the same time, the design of multi-layer densely arranged pipe bundles and multiple steel rings in each circle plays a good sealing and fixing role. It greatly eliminate smoke short circuits. zhongde Boiler's technical team use professional devices to remove the residual water from the water pressure test before the boiler leaving zhongde Boiler factory, which effectively compresses the boiling time of the thermal oil and greatly reducing the system exhaust time so that it can reduce customer’s time cost.
