GEA Plate Heat Exchanger NT250M Plates And Gaskets For Maintenance Cleaning

Plate Heat Exchanger Introduction

NT250M  Model Plate Heat Exchanger Specification
 

NT250M  Plate Heat Exchanger Technical Information

The HE plate pack consists of individual embossed HE plates with the asso- ciated HE plate gaskets.
The HE plate gaskets seal the flow media towards one another and the envi- ronment.
The number and the arrangement of HE plates depends on the requirements specified in the order.

NT250M Plate Heat Exchangers Application And Benefits

Application:

With M&C Heat Parts product group, the NT series is a gasketed plate heat exchanger for multiple applications. Variety of materials that work across a broad range of liquids, temperatures and pressures. Well-suited for these liquid-to-liquid applications:

Benefits:

Versatility-

• The right design, not a "good enough" design. A wide variety of materials, sizes, and plate configurations combine with sophisticated selection software to ensure a perfect selection, whatever your needs.
• The compact footprint allows you to use it in locations that you wouldn't dream of with a shell and tube heat exchanger.

Higher Performance at a Lower Cost -

• Optiwave plate corrugations distribute the liquid evenly across the entire plate width, maximizing heat transfer and minimizing the number of plates (and cost) required.

Convenient Maintenance-

• PosLoc plate lead-ins cause the plate pack to self-align when re-installing.
• Ecoloc tools-free gaskets make gasket replacement a snap.
• Individual plates mean no heavy lifting tools are needed. Faster more efficient maintenance, with shorter down times.

Long Service Life-

• Careful corrugation design provides the ideal balance of high turbulence and proper fluid distribution, reducing fouling from less than perfect media.

Plate Heat Exchanger Leak Conditions And Solutions

When the HE plate pack is tensioned to less than tensioning dimension a min., the HE plates are damaged. The PHE may become leaky and flow media can escape.

• Never tension to less than tensioning dimension a min.
• Ensure that the tensioning dimension a of the HE plate pack is always within the permitted value range a min. ≤ a ≤ a max.

Environmental damage due to leaks

• When using environmentally hazardous media, ensure that these can be reliably collected in case of a PHE leak (e.g. collecting trays and suction equipment) and cannot pollute the environment

Damage to PHE by sudden pressure rise (liquid hammer ) or sudden pressure drop (cavitation hammer)

When the flow velocity of a flow medium changes, a liquid hammer or a cavitation hammer may occur. This can damage the PHE and flow media can escape.

• Always open or close the valves of the piping connected to the PHE slowly.
• Avoid sudden condensation of gases by suitable process control.

Damage to PHE due to freezing of flow media

• Ensure that under all setting-up and operating conditions, the temperature never falls below the freezing temperature of the flow media used.

Leaks when putting multi-stage PHE into and out of operation

When putting multi-stage PHEs into and out of operation and failing to pressurize or relieve all sections evenly, the tensioning dimension may be exceeded in individual sections. This may produce leaks.

• Ensure that when putting multi-stage PHEs into and out of operation, all sections must be pressurized or relieved evenly.

Plate Heat Exchanger Commissioning
 

Initial commissioning of the PHE is to follow the conditions below: Before starting PHE commissioning, ensure

• That all required components of the PHE have been completely installed,
• That all piping connections are firmly connected with the PHE,
• That the tensioning dimension a of the HE plate pack is always within the permitted value range a min. < a < a max.
• That no residues from previous processes (e.g. cleaning media) are present inside the PHE when putting the unit back into operation.

Ensure that operating conditions are so

• That liquid hammers and cavitation hammers are avoided,
• That the PHE is not operated with unpermitted flow media, pressure or temperature levels.
• When integrating the PHE into your plant, ensure that the PHE is vented.

Safety instructions:Commissioning at very low ambient temperatures
If you wish to commission or re-commission the PHE at very low ambient temperatures, M&C Heat recommends to heat up the PHE slowly to the oper- ating temperature, using the flow media.

• Bring the PHE to the operating temperatures of the two circuits by means of the flow media at low pressure.
• In this process, cold leaks may occur briefly due to the low elasticity of the gaskets. These will disappear as soon as the operating temperature has been reached.

Safety instructions:Commissioning of multi-stage PHE
Ensure that when commissioning multi-stage PHE, all sections must be pressurized or relieved evenly.
