Product Description
VT20 Titanium SS316 Hastelloy NBR EPDM Viton Plate Heat Exchanger Seawater Desalination fresh water processorThe frame type plate heat exchanger is composed of a set of corrugated metal plates, which are made of stainless steel or titanium plates and other special materials. The plates are mounted with rubber pads and supported by the front and rear frames, pull bolts and other accessories. Through high and low temperature conversion and by two or more kinds of medium, the plates to achieve heat transfer, and sterilization effect. Our products are commonly used in shipping, chemical industry, petroleum, food, medicine, central heating and other fields. LJ has been constantly exploring and developing breakthroughs in new fields. At present, it has made some progress in waste water recycling.VT20 Parameters | Gasket Material | Temperature Range ( ºC) | Hardness | Available Medium |

Plate Theta: Low Theta and High ThetaVT20 Basic informationPlate heat exchanger gasket is one of the important parts of plate heat exchanger,which can produce plastic deformation and have certain strength.LJ's gaskets are customized to fit the customer's working conditions and are manufactured by a professional factory in a specified size.The contact width between the high pressure gasket and the sealing surface is very narrow ( line contact).Sealing PrincipleThe corrugated plate is pasted with sealing gasket, which is designed to double seal structure and has signal hole. When the medium leaks from the first seal, it can leak out from the signal hole, and the problem can be detected and solved as soon as possible, without causing the mixing of the two media. Sealing gasket according to different media and operation temperature to choose different types of gaskets.Brand Name: LJGasket Material: NBR,EPDM,HNBR,EPDM-HT,VITON,FKM

VT20 PHE Problem SolvingIf you have problems with your plate type heat exchanger, in most cases these can be solved by your own personnel. Please find below a summary of possible problems as well as possible causes and solutions.A condition for the continuous proper functioning of your plate type heat exchanger is in strict compliance with the permissible values for pressure and temperature mentioned on the name plate.Exceeding these values, even as a short-lasting pressure peaks will cause damage to the unit and be the cause of problems.To avoid costly repairs, we advise you to have the installation work and maintenance carried out by properly trained personnel. You can also contact us. | Problem | Possible Cause | Possible Solution |
| Leakage | At the connections | - Check the rubber liners (if fitted)
- Check the flange gasket(if fitted)
- Check the O-ring
- Fit the pipes tension-free
|
| Mixing of primary and secondary circuit | - Check the plates for holes and/or cracks
|
| In plate package | - Check the assembly
- Check the condition of the gaskets
- Check the proper position of the gasket
|
| The operating Conditions deviate from the specification | - Adjust the operating conditions
|
| Insufficient Capacity | Air in the system | - De-aerate the pipe system
- Check the pipe work for possible air traps
|
| The operating conditions deviate from the specification | - Adjust the operating conditions
|
| The heat exchanger is dirty | |
| The connections have been interchanged | |
| Too high pressure drop | Flow large the design flow | |
| Channels in plate(s) blocked | |
| Incorrect measurements | - Check the pressure indicator
|
| Medium deviating from the design | - Addition of for instance anti-freeze will increase the pressure drop
|
| Air in the system | - De-aerate the pipe system
- Check the pipe work for possible air traps
