Operating Conditions

Temperature & Pressure

Selecting a heat exchanger begins with understanding the temperature and pressure limits of the application. Every gasketed plate heat exchanger must operate within safe ranges to maintain performance and reliability. The SHPHE model offers a compact design that handles demanding environments with ease. Operators should always check the recommended ranges before installation.

This table shows the typical operating ranges for gasketed plate heat exchangers in industrial settings. Staying within these limits helps protect the unit and ensures efficient energy transfer. High efficiency depends on matching the heat transfer requirements to the correct design specifications.

In a plate HXCH a gasket separates the thin metal plates. The gasket acts to stop the contents escaping from the HXCH and to direct the flows within the HXCH. If incompatible gasket material is selected for the process chemicals and conditions then it will fail early. For example rubber gaskets have a limited temperature range. If the design selection assumes both liquids will be present and a rubber is selected because it will stay cool in the fluid flows then that will be a recipe for disaster.

This block quote highlights the importance of choosing the right gasket material. Operators must consider both the process chemicals and the expected temperature range. Exceeding design limits can lead to early gasket failure and loss of containment.

Flow Rate & Fluid Type

Flow rate and fluid type play a major role in selecting a gasketed plate heat exchanger. The SHPHE design supports a wide range of flow rates and adapts to different fluid properties. Operators should measure the flow rate and analyze the fluid before making a selection.

This table lists key fluid factors that affect the selection and efficiency of a gasketed plate heat exchanger. High viscosity fluids may require special plate patterns to maintain energy efficiency. Fluids with high particulate content can increase fouling potential and maintenance needs.

• Viscosity

• Corrosiveness

• Particulate content

• Fouling potential

Operators should review these factors to match the heat exchanger to the process. The SHPHE model offers high efficiency and a low fouling design, which helps maintain performance over time. Proper selection ensures the unit meets heat transfer requirements and delivers reliable operation.

Materials & Design

Plate & Gasket Selection

Selecting the right materials for a gasketed plate heat exchanger is essential for reliable operation and long service life. The choice of plate and gasket materials depends on fluid compatibility, corrosion resistance, and the specific heat transfer requirements of the application. Stainless steel, titanium, and Hastelloy are common plate materials. Stainless steel works well for most water-based and mild chemical processes. Titanium resists corrosion in seawater and aggressive fluids. Hastelloy provides excellent durability in highly corrosive environments.

Gasket selection also plays a critical role in performance and compatibility. Operators must match gasket material to the chemical and temperature conditions of the process. EPDM gaskets perform reliably in water and steam systems, handling temperatures from -50°C to 150°C. Nitrile gaskets suit hydrocarbon-based applications, with a temperature range of -40°C to 120°C. Viton gaskets excel in high-temperature, high-pressure, and chemically aggressive environments, tolerating temperatures up to 250°C.

Tip: Always verify fluid compatibility before selecting plate and gasket materials. This step helps prevent early failure and ensures optimal performance.
