Frequently Asked Questions - EATB28-100 Vevor

What is the maximum operating pressure of the EATB28-100 heat exchanger?

The maximum operating pressure is 3.0 MPa.

How to prevent frost in the heat exchanger?

To prevent freezing, use a protection thermostat and a constant water flow. If stopped, drain the water. If the evaporation temperature is near freezing, add antifreeze (glycol) to the water.

What is the tightening torque for the connectors of the EATB28-100?

The tightening torque for threaded connectors is 400 Nm.

How to clean the heat exchanger?

Regular backflushing is recommended. In case of scaling, chemical cleaning with a weak acid (formic, citric) should be done counter-current for about 24 hours, followed by a rinse with clean water for at least 30 minutes.

Which fluids are compatible with the heat exchanger?

Compatible: refrigerants (except ammonia and chlorine), DI water, oil, steam, organic solvents and gases. The pH should be between 6 and 8.

What are the dimensions and weight of the EATB28-100?

Dimensions: 301 × 126 × 248 mm. Net weight: 15.2 kg.

How many plates does the heat exchanger contain?

The heat exchanger contains 100 plates.

How to avoid refrigerant leaks?

Use brazed valves to prevent leaks. Ensure a tight connection with a suitable gasket and respect the recommended tightening torque.

What is the maximum brazing temperature?

The maximum brazing temperature is 650 °C (1202 °F). Use silver-based brazing rods at 40-50%.

How to install the heat exchanger correctly?

Install the heat exchanger vertically according to the nameplate diagram. Use a suitable support and, if necessary, dampers (rubber pad, corrugated pipe) to avoid vibrations.

Security & Warnings

1. This product should be used for welding spigots when using to avoid refrigerant leakage.
2. If undissolved solids like sand, weeds, leaves, and other fibers are in the water, the channels are easily blocked; we recommend up to 40~70 mesh strainer to avoid blocking. 3. Any heat exchanger could freeze up when the temperature is zero. Freezing up inside the heat exchanger will result in structural damage and leaking. If leaking happens in the evaporator, ever compressor could be destroyed. In order to avoid freezing: * Use a freeze protection thermostat and flow switch to guarantee consistent water flow before, during and after compressor operation. * Avoid operating the unit during pump downtimes. Discharge the water when the exchanger is left unused and keep heating the water in use. * Use antifreeze when the evaporating temperature is close to freezing. Adding glycol or other antifreezing in the water.
3. Cleaning: Regular reverse flushing in situ is the simplest option, however, if scaling has occurred, chemical cleaning will be necessary. Clean with detergents for fatty deposits (without chlorine), for he

Fouling: use chemicals compatible with copper and stainless steel, such as formic acid, citric acid, or any other organic acids. Use a weak acid solution pumped through the heat exchanger in reverse flow direction at approximately twice the normal flow rate. Remember that the acid should be circulated in reverse flow for usually 24 hours. After completion of the cleaning process, it is important that the unit is flushed with clean water for at least 30 minutes.

5. Suitable Medium:

* Any refrigerants except ammonia, chlorine, and DI water * Water, vapor * Oil, organic solvents, gas * pH 6~8

*Please pay attention to the operating temperature and design of the PHE.

Operation

1. Screw thread link

In order to avoid danger to the components, there will be no link between the BPHE and the piece; you need to use a screw airproof circle to airproof. Use the torque wrench and refer to the data table to do the screw thread link.

Model	Torque
EATB12-30/40/60	《170 Nm
EATB28-30/50/80/100	《400 Nm
2. Copper brazing linkClean the weld surface and brush the flux, using 40-50 silver-based rods for welding; the maximum temperature does not exceed 650 (1202F); cooling water into the water-side and in the vicinity of t welding department to impose an appropriate cooling and the refrigerant-side injection with Nitrogen to avoid oxidation.
3. Bolt FasteningIn order to avoid excessive torque lead to bolt come off and t cover plate deformation, using the measuring wrench according t data listed on the table to fasten the bolt.

Please refer to the nameplate's connected tube sketch and installation drawing. Moreover, the customer should configure a connected tube accurately, and install the brazed plate heat exchanger vertically.

If the pipeline has vibration, longer pipe, and higher thermal expansion, which will affect the brazed plate heat exchanger. You'd better consider adopting the following devices: install rubber pad between the brazed heat exchanger and bracket; compressor with shock absorber, a corrugated pipe, or other damping devices when straight pipe is used.

Correspondingly, there is a certain gap between the relative corrugated plates pointed by arrows here. They are not welded together and thus leave an opening for the liquid in the angle holes to get in.
