When it comes to plate heat exchanger components, everyone must think of rubber strips and plates for the first time. They think that the plates and rubber strips are the main body of heat exchange. Other parts such as frame plates are not important. 
The role of the frame is not to be underestimated in the part of "film and tape", and it is also a key point to reflect the beauty of craftsmanship. What is going on?

Some customers reported that when buying a plate heat exchanger, the frame plate looked shiny and slippery, but it didn’t take long before the paint began to fade and peel; this was considered good, and some of the plates did not have any problems, the bushing, 

The flanges started to strike first; what's more, in order to save the budget, the choice of frame plates is simply not acceptable, and they have to be returned to the factory as soon as they leave the factory.

However, buyers who bought these parts from Raptor never complained or replaced them. Instead, they became a loyal user of Raptor. How did Raptor do it?

It's simple, use the best raw materials and technology to create the best parts.

For example, the board and frame, from cutting to baking, only one step must be painted with customized paint to go through 6 processes. The light-proof frame board is not only beautiful and textured, but also does not peel off the paint, and it will not corrode; 
Holes and tapping are made of CNC technology, and the location selection and processing are very precise, so that customers can save time and effort during assembly. 
And when you use the requirements completely higher than the industry standard for processing, how can such a frame not have uniform force and large pressure?

As for the bushing, we use the best stainless steel to do it. Basically, we do not recommend customers to use rubber products, so that there is no worries about the operation of the heat exchanger.

RPT has been using the spirit of making handicrafts and strictly requires its own industrial production, with zero return to the factory record, which is deeply trusted by customers.
