Frequently Asked Questions - EATB28-80 Vevor

How to install the EATB28-80 heat exchanger?

Mount the device vertically using a mounting bracket. Connect the pipes with a torque of 400 Nm for the 1-1/4\" NPT connections. If the circuit has vibrations, install a rubber buffer or a corrugated pipe.

What is the torque for the connections?

For the EATB28-80 model, the recommended torque is 400 Nm. Use a torque wrench to avoid damaging the threads.

How to prevent freezing in the heat exchanger?

To prevent freezing, use a freeze protection thermostat and a flowstat to maintain constant water flow. You can also add glycol-based antifreeze or drain the water if not used for a long time.

How to clean the heat exchanger?

Perform backflushing regularly. For scale, use a chemical cleaner based on formic or citric acid (compatible with copper and stainless steel). Let it circulate backflush for about 24 hours, then rinse with clean water for 30 minutes.

What fluids are compatible with the heat exchanger?

The heat exchanger accepts water, oil, steam, and organic solvents (except ammonia, chlorine). The fluid pH must be between 6 and 8. Avoid suspended solids by installing a 40 to 70 mesh filter.

What is the maximum operating pressure?

The maximum operating pressure is 3.0 MPa (approximately 30 bar). Do not exceed this limit to avoid any risk of leakage or damage.

How to choose the right heat exchanger size?

Use the selection form provided in the manual: enter the inlet/outlet temperatures and flow rates of both fluids. For an unknown heating capacity, provide the flow rate. Consult the dimension table for the model suited to your needs.

What to do in case of a leak?

Stop the device immediately. Check the connections and tighten to the recommended torque. If the leak persists, internal freezing may be the cause; defrost and inspect the plates. Contact technical support if necessary.

Where to find Vevor technical support?

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 in the water, the channels are easily blocked; we recommend using a 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 operation the unit during pump downtimes, Discharge the when the exchanger is left unused and keep heating the water use. *Use antifreeze when the evaporating temperature is close to like freezing, Adding glycol or other antifreezing in the water.
3. Cleaning: Regular reverse flushing in situ is the simplest option, however, 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 on the PHE.

Operation

1. Screw thread link

In order to avoid danger to the components, there will be no link between BPHE and the piece; you need to use a screw airproof circle to airproof. Use the ergometer to 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 nameplate's connected tube sketch and installation drawing. Moreover, customer should configure a connected tube accurately, and install brazed plate heat exchanger vertically.

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