Skip to content Since more than 30 years, CALORPLAST Plastic heat exchangers are the benchmark for heat transfer solutions in corrosive environments. The unique and patented modular system that combines the efficiency and reliability of a serial product with the flexibility to design fully customized solutions to meet your high expectations. Thermoplastic Immersion Type Heat ExchangerPlastic immersion type heat exchangers are essential components in the surface finishing and chemical process industries. The CALORPLAST polymer immersion-type heat exchangers are suitable for heating and cooling of highly concentrated acids and alkaline liquids (Polyethylene), high-purity media or aggressive and scale depositing fluids in tanks and vessels. Corrosion Resistant Gas-Liquid Heat ExchangerThe CALORPLAST all-plastic gas-liquid heat exchanger is manufactured entirely from thermoplastics and is used for heat recovery as well as for cooling and heating of high volume gas flows. The heat exchanger is designed to transfer heat from a corrosive vapor stream to a liquid stream for heat recovery or other process use. PVDF High purity Shell and Tube Heat ExchangerThe PVDF shell and tube heat exchanger features a compact design and a very high heat transfer capability, due to the use of thin-walled, non-fouling tubes. Utilizing a traditional shell-and-tube design, the CALORPLAST thermoplastic shell and tube heat exchanger is an external heat exchanger for cooling, heating, condensing or evaporating of high-purity media. Plastic Gas-Gas Heat ExchangerEntirely made from non-metallic material, the CALORPLAST plastic gas-gas heat exchanger allows efficient heat recovery of polluted exhaust gases in highly acidic environments. The heat exchanger is a completely new and innovative device for heat transfer between two gases. Due to the polymer design, the risk of damaging corrosion resistant linings is completely eliminated and guarantees long term use of the equipment. Thermoplastic Tube Plate Heat ExchangerPolymer tube plate heat exchangers are often used in the surface To represent a range of common heat exchangers, ESDU, 93012. Approximately 90 geometries were represented by an expression with 14 variable coefficients. The curve fitting approach matches the exact relationships to better than 2%. By incorporating the algebraic expression into a computer program, a range of geometries and designs can be readily accessed. The accuracy of the computer calculations does not, however, bring any increase in the accuracy of the overall method.F values or effectiveness-NTU relationships are obtained by making simplifying assumptions about the geometry of a heat exchanger and then carrying out a process of integration. The integration can either be carried out algebraically (most designs of shell and tube heat exchanger) or using finite element methods (most designs of crossflow heat exchanger). In all but the simplest of geometries, the process of integration is complex. For shell and tube exchangers, the resulting algebraic expressions require care in application to avoid error. For example, for the single E-shell with any even number of passes, the expression linking NTU with E is(7)whereand(8)For crossflow heat exchangers, particularly with more than one pass, the finite element integration often involves iteration as well. Users of mean temperature difference techniques are therefore advised to use the graphical presentations of these integrations or curve fits to the data.Table 1 gives references to sources of graphical data for various types of heat exchanger.Table 1.

The Carotek Heat Exchanger Selection Guide provides a model of the heat exchanger sizing and selection process.Heat exchangers are used throughout industrial processes whenever heat needs to be transferred from one medium to another. Understanding how to size and select a heat exchanger benefits both productivity and the bottom line. Types of Heat ExchangersBy its most basic definition, an industrial heat exchanger transfers thermal energy from one fluid to another without mixing them. Heat exchangers can be generally classified into a few main types:Shell and Tube heat exchangers consist of a shell enclosing a number of tubes. Because they are widely used, these versatile heat exchangers are generally well understood. The shell and tube design helps these heat exchangers withstand a wide range of pressures and temperatures.Plate and Frame heat exchangers are compact, efficient products designed with a number of stacked heat transfer plates clamped together within a frame.Gasketed Plate heat exchangers feature titanium or other nickel alloys for accurate fluid temperature control for heat recovery. These designs are often used for food or sanitary applications.Brazed Plate heat exchangers are constructed without gaskets, and they are suited for greater range of pressures and temperatures. Available in materials like copper or nickel, these corrosion resistant heat exchangers are suitable for many applications.For any given application, there is usually more than one heat exchanger design that could be used. A starting point for heat transfer solution sizing and selection is to compare models that fit the temperatures and pressures required for the process. The best type of heat exchanger depends on design parameters, fluid characteristics, space, and budget.Main Criteria for Heat Exchanger Sizing and Selection Function that the heat exchanger will perform (whether condensing, boiling, etc.) Pressure limits (high/low), which may vary throughout the process, and pressure drops across the exchanger Approach temperature and temperature ranges (which may vary throughout the process) Fluid flow capacity Materials requirements. Conditions like sudden temperature changes or corrosive media may require special materials. For a gasketed plate heat exchanger, the gaskets must be compatible with the fluids in the unit. Thermal fluid characteristics and product mix. If the heating or cooling fluid is susceptible to fouling, a corrosion resistant material may be needed. Location. Some exchangers may require cooling water, steam, or hot oil, and they may be relevant options only where these utilities are available. Footprint. Space limitations and layout may also affect which heat exchanger models are suitable. Keep in mind that lower approach temperatures generally correlate to larger units. Maintenance requirements. Depending on housekeeping procedures, it may be useful to choose a design lends itself to easy cleaning. Ease of repair or inspection may be a factor as well.Generally, more than one heat exchanger model will work for a given application, so additional criteria may help in evaluating the best fit. Consider factors like future scalability, overall cost to purchase and operate, and efficiency/carbon footprint to narrow the options.Importance of Sizing a Heat ExchangerOnce a heat exchanger design is selected, the most efficient. tube heat exchanger using HTRI software.

The guessed value is adjusted until convergence is achieved.Published relationships for F in graphical form are available for most geometries of shell and tube heat exchanger and a range of geometries of crossflow heat exchanger (see guide to references at the end of this section). The size of the graphical presentations rarely allows values of F to be estimated to better than two significant figures. This accuracy of estimation is consistent with the overall accuracy of the mean temperature difference approach and the lack of compliance with the underlying assumptions. Attempts to improve the accuracy in the estimation of F values are therefore unlikely to produce significant benefits for heat exchanger designers.An alternative method of presenting mean temperature difference information is known as the effectiveness—NTU method. This method is based upon exactly the same initial assumptions. The heat transfer behavior are presented as a relationship between effectiveness, E (defined in a similar way to P), the ratio of the thermal capacities of the streams, R, and the number of heat transfer units, NTU which as calculated from the expression(6)where ()smaller is the smaller of ()1 and ()2.Unfortunately, the parameters E, R and NTU are again not consistently defined and any user should check the definition used by the supplier of data and apply those definitions when using the data.Effectiveness-NTU information is typically presented graphically as the relationship of effectiveness against NTU for various values of R. Figure 2 shows a typical relationship. This shows that the effectiveness tends to zero as the NTU tends to zero and the effectiveness tends to a maximum value as NTU becomes large.Figure 3. Typical relationship between E and NTU for various values of R (Based on Single E-shell with any even number of tube passes).Users of the effectiveness-NTU technique are not required to calculate the log mean temperature difference when carrying out design or rating calculations. For design calculations, E and R can be calculated from the mass flowrates, specific heat capacities and inlet and outlet temperatures. The value of NTU can be read from the graph for the chosen design of heat exchanger and used to calculate the required surface area. In rating calculations, the surface area, mass flowrates and specific heat capacities can be used to calculate R and NTU. The value of E can be read from the graph and used to calculate the rate of heat transfer in the heat exchanger. It can therefore be argued that the effectiveness-NTU method can be used for rating calculations without the need for an iteration. In reality, since heat transfer coefficient will change with temperature, it is still likely that an iterative calculation will be required.Effectiveness-NTU relationships are generally presented graphically and may be used to produced estimates to two significant figures. Again, because of deviations from the underlying assumptions, this level of precision in the calculations is consistent with the precision of the overall method. An attempt has been made to produce a single algebraic expression with a number of variable coefficients

Location …but no mention of the fact that the 94°F occurs at 3 PM and the 100% relative humidity occurs at 3 AM when the air temperature is 65°F. Given the exponential shape of the dew point curve, it would grossly overstate the amount of moisture in the air to take data like this and presume the average high temperature/humidity is 94°F and 100% relative humidity.The capital and operating costs (e.g. refrigeration) of heat exchangers that cool below dew point are exponentially related to the specified dew point. Notice how the curve above is trending towards a vertical line as temperature increases. Overly conservative humidity specifications make projects financially unjustifiable and have kept a lot of beneficial systems on the drawing board. Please take care to specify a realistic dew point, or ask us and we’ll look up the ASHRAE design climate data for the installation site.Q. How is heat transfer duty calculated?Heat transfer can be classified in two ways:Sensible heat transfer, also known as temperature change. For example, it takes one BTU to raise one pound of water one °F. The key relationship here is:Q = Cp • M • TDWhere:Q is BTU/hrCp is heat capacity in BTU/lb-F (the Cp of water is 1)M is mass flow in lb/hrTD is Temperature difference in °FLatent heat transfer, also known as phase change. For example, it takes 1000 BTUs to boil one pound of liquid water into steam – at the same temperature. The key relationship here is:Q = Hfg • MWhere:Q is BTU/hrHfg is the latent heat of vaporization in BTU/lb (the Hfg of water is 1000)M is mass flow in lb/hrQ. How is heat exchanger performance calculated?Heat exchanger design starts looking just as simple, but it gets much more interesting! Heat exchangers are machines that get fluids to transfer their heat. Most heat exchangers work with two fluids flowing through separate passages, for example cold water flowing inside a tube and warm air flowing outside the tube. When this happens, the cold fluid warms up and the hot fluid cools off. The key relationship here is:Where:A is the required amount of surface area in ft2Q is duty in BTU/hrU is the performance of the heat exchanger in BTU/hr-ft2-°FLMTD is the mean temperature difference throughout the heat exchanger in deg FQ. How is a U value calculated?The U value is the heat exchanger’s performance coefficient, it’s based on the unit’s design, materials and the fluids that flow through. A heat exchanger made from aluminum will have a higher U value than one made of plastic, because aluminum is a better conductor of heat. A heat exchanger using water as coolant will have a higher U value than it would using air as coolant, because water is a better coolant. The key relationship here is:Where:U is the performance coefficient for the heat exchanger in BTU/hr-ft2-°Fh1, h2, h3, etc. for a fin tube, air-to-water heat exchanger are heat transfer coefficients typically:air, fin, tube, water.R1, R2, R3, etc. is the thermal resistance of. tube heat exchanger using HTRI software.
