Certifications

The following are certifications/testings which apply to all of our heat exchangers:



Heat Exchanger Characteristics

Dimensions L: 7.5" W: 2.9" H: 1.22"
Heat Transfer Area/Plate 0.012 m²/plate (.14 ft²/plate)
Thickness of plates 0.3 mm (.0118")
Max Flow Rate 66.6 L/min (17.6 gpm)
Channel Capacities 0.018L/channel (.004756 gal/channel)
Design pressure 1.0 Mpa (145 psi)
Test Pressure 2.0 Mpa (290 psi)
Design Temperature -195°C to +220°C (-319°F to 430°F)
Refrigeration Capacity 1-5KW (3400-17,000 BTU/hour)
Flow direction F1-F3 and F2-F4 (see diag above)
Welding Material 99.9% Copper
Corrosion Resistance SS304 has good general corrosion resistance to a range of organic and in-organic fluids. It will have poor resistance to sulfuric and hydrochloric acids. Crevice corrosion may also occur when chlorides (salts) are present in the fluid. Since chlorides are in all natural sources of water it is best to use distilled water whenever possible. typically, a unit will last about 10 years with regular tap water depending on salt content. Not recommended for use with salt water.
Manufacture Material Stainless Steel 304
Applications SVO conversions, Heat pump system, household type central air conditioning, after heat recycling, refrigeration equipment, industry cold water machine,cooleroil and so on
UL Listed Yes - TUVReinland ISO9001:2000

We carry many different sized copper brazed plate heat exchangers, with various welded-in fitting options & varying number of plates.

These units may be used for SVO conversions, beer wort chilling, biodiesel cooling or heating, refrigeration & boiler applications.

Stainless Steel Copper Brazed Plate Heat Exchangers

How Heat Transfer Works

Heat transfer occurs when there is a difference in temperature between two mediums. Heat will travel from the hot source to the cold source. The rate at which the heat transfer occurs at is determined by many factors such as the heat conductivity of the two materials andthe difference in temperatures of the two mediums. Convectiuve heat transfer occurs when the materials are moving against each other.

Plate heat exchangers have significantly good heat transfer rates because they use metal plates which have high heat conductivity rates and the plates are extremely thin. The plate heat exchangers also achieve high amounts of heat transfer through convective forces with both working fluids. With large temperature differentials, great amounts of heat transfer can be achieved using a plate heat exchanger.

Corrosion

Corrosion is usually how these units will fail. Use fluids with reasonable pH levels to ensure a long lasting life. Hard water will corrode faster than regular water. (Use distilled if possible; Distilled should never corrode it) Salt water will corrode stainless steel very fast. It is recommended to clean the exchanger often if you are using corrosive fluids. Normal usage (non-corrosive fluids) should expect 10-20 years of life. Fluids containing chlorides will corrode the unit quickly.

Applications

This is an extremely popular unit for wood burning furnaces, radiant floor systems, refrigerant systems, straight vegetable oil conversions, beer chilling, air conditioning system and solar water heating systems. It will work for any application in which the desired result is for two fluids (liquid or gas) to exchange heat.

How a heat exchanger works

This image shows a counter flow configuration. Counter flow is the most efficient configuration since in theory, the cold fluid can reach the same temperature as the hot fluid.

How it Works

Fluid A passes from the port on the left of the heat exchanger through every other channel created by the plates to the opposite end port on the left of the heat exchanger (looking at it the long way). Fluid B passes from the port on the right through the other channels created by the plates and comes out the other port on the right side. The fluids are essentially touching each other through the plates and heat is transferred from the hot fluid to the cold fluid. (but the fluids do not mix)

Performance

Beer Wort Chilling - Please see the following charts for performance estimates on applications specific to beer wort chilling.

Beer wort chilling chart (pdf)

Heat Exchanger Sizing

Generally speaking, the more length the heat exchanger has, the more efficiency in heat transfer it has. An infinitely long heat exchanger would allow for the hot fluid to become the temperature of the cold fluid and the cold fluid the hot fluid, assuming perfect energy balance.

The more plates and more width the heat exchanger has, the less pressure loss to the fluids flowing through. While adding more plates and width may increase some heat transfer, it is best to add more length for optimal heat transfer gain. More plates and width should be considered when flow rates reach half or more the max flow rate for the particular unit to avoid pressure loss in the fluid flow. Pressure loss means a slower flowing liquid and therefore, less heat transfer overall. In our designs, we typically allow up to a 7 psi pressure drop. Most small applications experience less than 1 psi drop.
