With excellent product quality and comprehensive customized services, ZOZEN Boiler has opened up the new overseas market of Moldova, has become a partner of Granit Unic, a well-known enterprise in the building materials industry, and has formed a good market reputation in the Russian-speaking regions, direct fired oil heaters.
ZOZEN WNS series gas-fired (oil-fired) boilers are wetback fire-tube boilers with a two-pass or three-pass design. It uses threaded smoke tube for heat transfer and manages to achieve a thermal efficiency up to 98%. The economizer is installed at the tail of boiler, giving the boiler a compact size. Meanwhile, sound automatic control system enables unattended operation.
direct fired oil heaters, As a pioneer of industrial boiler industry, ZOZEN Boiler has always been committed to the research, development and manufacture of industrial boilers since its establishment in 1988. Researching the market demands carefully, ZOZEN officially launches a new type of gas/oil-fired skid-mounted boiler which has the advantages of sufficient output, easy installation and fully automatic and safe operation.
The boiler hydrostatic test is a test of strength and tightness with pressurized water after the boiler or components are assembled. The main purpose of the hydrostatic test is to test the tightness and compression strength of boiler pressure-bearing components, tell whether there is leakage of welding seams, flange joints and pipe expansions, and watch the deformation conditions of pressure-bearing components with naked eyes. Practice has proved that the boiler defects can be found through the hydrostatic test, and the safety of boiler operation can be ensured after the corresponding measures are taken in time. Therefore, the hydrostatic test is an important step and means to ensure the safe boiler operation, direct fired oil heaters.
Over the past 40 years of reform and opening up, our country’s wood processing industry has achieved considerable development. Processing logs into the boards that we use is inseparable from the high-temperature steam produced by the boiler for drying. As a large-scale industrial boiler manufacturer with a history of more than 30 years, ZOZEN Boiler has accumulated rich project experience in the wood processing industry. It has achieved the win-win cooperation with Langfang Jiarun Wood Company, Jiangsu Baoyuan Wood Company, Shandong Jiulefu Wood Company and many other enterprises, direct fired oil heaters.
