GEA VT40/VT40P/VT40M Stainless Steel Plate Heat Exchangers Plates and Gaskets
VT40/VT40P/VT40M Plate Heat Exchanger Basic Design
The basic structure of a PHE is shown below. The specific execution depends on the application.
Components of a gasketed PHE
| No. | Component | No. | Component |
| 1 | Top beam | 6 | HE plates |
| 2 | Piping cinnections | 7 | Bottom guide beam |
| 3 | Fixed plate | 8 | HE plate gasket |
| 4 | Column | 9 | Nut on tensioning bolt |
| 5 | Loose plate | 10 | Tensioning bolts |
The HE plate pack consists of individual embossed HE plates with the associated HE plate gaskets.
The HE plate gaskets seal the flow media towards one another and the environment.
The number and the arrangement of HE plates depends on the requirements specified in the order.

VT40/VT40P/VT40M Gasketed Plate Heat Exchanger - Varitherm Systematic Product Variety
Whether in heating or cooling of liquids containing particles of up to 2mm in size, in condensing vapours or in gas cooling and gas dehumidifying in special cases- Varitherm plate heat exchangers offer a convincing solution with the widest range of possible applications.
The Varitherm Series has two convincing arguments in its favour. Firstly there is a wide range of materials available, including 1.40301/AISI304, nickel-based alloy, Incolloy, nickel, tantalum and titanium. Secondly it comes with an individual plate pack that can be easily expanded to meet your future needs. And this makes the Varitherm Series the optimum economic solution for just about every application.

Gentle product handling
The gentle treatment of products caused by the soft corrugation makes the Varitherm the obvious choice for the foodstuffs industry.
PHE Type of Safetherm and Varitherm
| Safetytherm | VT10 VT20 VT40 |
| Varitherm | VT04 VT10 VT20 VT40 VT80 VT130 VT180 VT250 VT405 VT805 VT1306 VT2508 |
VT40/VT40P/VT40M Frame
PHEs are available in various application-specific frame versions. The basic versions are the C and B designs, with the B design being used above all for longer plate packs.Variants of these designs are marked by further abbreviations.
Special Stianless steel versions are employed in foodstuff and pharmaceutical applications and may include intermediate plates for separating the individual sections.
Some frames are equipped with height-adjustable bases
PHE Troubleshooting
1. Insufficient Performance
| Fault | Cause | Remedy |
| Reduced heat transfer | Deposits on the HE plates | Clean HE plates - Cleaning HE plates while PHE is open and cleaning HE plates while PHE is closed. |
| Operation, flow media etc. differing from the design case | Have PHE design with new operating data checked by M&C | |
| Excessive pressure loss | Plugging of manifold flow gaps obstructs flow | Clean HE plates - Cleaning HE plates while PHE is open and cleaning HE plates while PHE is closed. |
| Incorrect installation of HE plates obstructs flow | Check installation order by means of circuit diagram | |
| Operation, flow media etc.differing from the design case | Have PHE design with new operating data checked by M&C |
2. Leaks
| Fault | Cause | Remedy |
| Leaks between the HE plates - flow media escape from the HE plate pack | Incorrect tensioning dimension of PHE | Check correct tensioning dimension according to rating plate data |
| Excessive operating pressure | Check operating pressure according to rating plate data | |
| Operating temperatures too high/too low | Check operating temperatures according to rating plate data | |
| HE plate gaskets are not properly seated | Open the PHE and correct the seat of HE plate gaskets | |
| HE plate gaskets are soiled | Open the PHE and clean the HE plate gaskets | |
| HE plate gaskets either defective or hardened | Open the PHE and replace the HE plate gaskets | |
| Leaks between HE plates and frames, reinforcement plates and intermediate plates | Incorrectly seated HE plate and frame gaskets | Open the PHE and correct seat of plate and frame gaskets |
| HE plate and frame gaskets are soiled | Open the PHE and clean the HE plate and frame gaskets | |
| HE plate and frame gaskets are defective | Open the PHE and replace the HE plate and frame gaskets | |
| Leaks between frame connection and pipework | Excessive load of frame connection from pipework | Reduce connecting loads to permitted values |
| Gasket improperly seated | Slacken off frame connection and correct gasket seat | |
| Dirty gasket | Slacken off frame connection and clean the gasket | |
| Defective gasket | Slacken off frame connection and replace the gasket | |
| Flange connection is not sufficiently tightened | Check gasket and retighten connection evenly if required | |
| Damaged HE plates | Excessive tightening of HE plate pack (tensioning dimension below a min.) | Replace defective HE plates |
| Damaged HE plates | Corrosion of HE plate material | Check design of PHE regarding flow media, contact M&C |
| Damaged HE plates at the beginning or at the end of the PHE | Incorrect earthing when welding on special connections to open frame connecting pipes | Repalce defective HE plates |
