 Brazed Heat Exchangers
The brazed heat exchanger is the most advanced form of the compact plate heat exchanger especially designed for a wide range of applications in both process and hydronic applications. These heat exchangers are also widely used for refrigeration applications as evaporators, condensers and sub-coolers.
Operating Principle
The brazed plate heat exchanger has a simple operating principle. Based on the plate and nozzle orientation, each fluid passes through alternative channels within the heat exchanger. All plate material and nozzles are Stainless Steel 316 with 99.9% copper used for brazing the heat exchanger together.
An extremely high heat transfer coefficient is attained due to the flow characteristics in each channel. A specially designed and tested chevron pattern causes a turbulent flow of the fluid resulting in higher heat transfer.

Advantages of the Brazed Heat Exchanger
Compact:
Due to the high efficiency of the brazed plate heat exchangers, these heat exchangers are often half the size of conventional shell & tube heat exchangers. The smaller footprint also makes it easier to be installed on skid systems and portable equipment packages.
High Efficiency:
Due to the turbulent flow of the fluid in the channels, the heat transfer coefficients of our brazed plate heat exchangers are 3-5 times higher than that of a conventional Shell & Tube heat exchanger for a similar application.
Rugged Construction:
The brazed plate heat exchanger is brazed using 99.9% copper. The copper provides a strong bond when heated in a special furnace, keeping the plates bonded together. The heat exchangers have a high pressure-temperature rating. All our copper brazed heat exchangers are rated for 413psig, 406 degrees..
Closer Approach
The brazed plate heat exchanger can provide a temperature approach of 1 degree F. This allows for maximum utilization of waste heat recovery.
24-Hour Service:
We can be reached on a 24 hour basis, 7 days a week for any replacement of heat exchangers on an emergency basis.
Stock:
We stock a complete range of brazed plate heat exchangers at our facility to meet all your heat transfer requirements.
