With the wide application of plate heat exchangers, there are many domestic manufacturers of plate heat exchangers. However, in terms of the actual heat exchange effect of the equipment, its quality is indeed very different, especially for industrial use like quenching liquid cooling. 
Each manufacturer can achieve the results you expect.


Quenching fluid can meet the quenching needs of almost any steel to obtain ideal quenching performance. It overcomes the shortcomings of fast water cooling and easy cracking of the workpiece; slow oil cooling, poor quenching effect and flammability. 

The continuous quenching of the workpiece makes the temperature of the quenching liquid increase and the cooling rate slows down. In order to keep the temperature of the quenching liquid constant within the usable range, the use of the quenching liquid cooling plate heat exchanger is particularly important.

Qingdao RPT has been researching and producing plate heat exchangers for 13 years. In the working conditions of the quenching liquid, the quenching liquid cooling plate heat exchanger has been widely used and recognized by customers. Through different plate angles and corrugation depths 
The design greatly improves the heat exchange performance, makes the heat exchange effect of the medium more sufficient, and more satisfies the requirements of workpiece quenching.


Qingdao RPT’s strict process flow and high-quality raw materials, and the products have strict inspection procedures at the factory, so that every quenching liquid cooling plate heat exchanger produced can reach extremely high quality, and the products comply with CE and ASME 
System certification, quality assurance, so that you can use it at ease and comfort.
