All units are produced at our global production facilities with our proprietary production equipment according to the same standardized processes, ensuring uniform product quality and favorable lead times worldwide. Our products are field tested and have proven to deliver a fast ROI. Particularly in industrial applications such as process air systems, cross-flow plate heat exchangers must often withstand extreme temperatures. Both sensible and latent heat may be transferred. Model P is our most robust aluminum cross flow plate heat exchanger. Plate exchangers are often built into systems in which air circulation is unwanted. Custom made accessories like bypass and dampers are available for all our cross-flow heat exchangers. Latent heat when moisture in the outlet air condensates on the recuperator. Join our newsletter to stay up to date on features, releases and more. Moisture is not transferred. Tweet 0. Both sensible and latent heat may be transferred. © 2010 - 2020 Energy Recovery Industries Corp. S.r.L. Available in aluminium, epoxy-coated aluminium or stainless steel as required.Ideal for use in industry, in ventilation and extraction systems, for adiabatic cooling and for cooling electrical cabinets.Our cross-flow exchangers are available as individual units with edge lengths from just 200 to 1200 millimetres. Our special sealant has an adhesive effect that blocks off all possible nooks, niches or gaps that could be colonised by bacteria.Consequently all condensate flows out of the exchanger, leaving no residue whatsoever. If you continue to use this site we will assume that you are happy with it. Model P is a heavy duty, cross flow plate heat exchanger, specially designed for applications where high differential pressures occur. ME 3264 Lab 3: Cross-Flow Heat Exchanger 1 ME 3264: Lab 3 Department of Mechanical Engineering, University of Connecticut Cross-Flow Heat Exchanger Professor Wilson K. S. Chiu Spring 2017 Objectives The objectives of this experiment are: (a) Understand and practice basic heat exchanger analysis methods. All Heatex cross flow plate heat exchangers meet several hygiene requirements. Please contact our manager by phone +39081 188 572 23 or info@ericorporation.com. View from below of a high-temperature plate heat exchanger tower over eight metres high. This will also improve the already high tightness of the exchanger and limit leakage to a minimum. Get in touch! Share this. This tower is used to produce washing powders. This can be seen by comparing the graphs in Figure 3, Figure 4, and Figure 5. For improved corrosion protection in demanding applications such as in coastal environments, all Heatex aluminum heat exchangers are available with epoxy coated plates. Maximum impermeability is thus called for – and our plate heat exchangers deliver.Larger models with edge lengths of 500 mm or more and potentially exposed to particularly high pressures are double-folded at the inflow edges, which gives them exceptional sealing.The double fold gives the edges five times the strength of the construction material, lending the plate exchanger outstanding stability, however high the air pressure. We invite you to view a short video clip, showing the physical processes of our technology. (b) Measure the hot and cold fluid temperatures and mass flow rates.

In a crossflow heat exchanger heat is transferred directly from the outlet air to the make up air through the separating walls of the heat exchanger. Their modular construction means that we can deliver any desired edge dimension and package length. Very high differential pressure resistance, A single pass exchanger can provide a sensible efficiency of 65 – 70%. Well-proven plate design creates turbulence even at lower velocities which, combined with high channel heights, results in a low-pressure drop and a total increase in efficiency. Therefore the log mean temperature for a counter flow heat exchanger is larger than the log mean temperature for a similar parallel or cross flow heat exchanger. For the highest corrosion protection, we recommend adding both Epoxy Coated Plates and Closed Plate Cutting Edges. Airflows at temperatures of up to 300°C are no problem for our stainless steel models.We offer various module variations to meet your requirements, together with installation-ready housings. Share 0. Dynamic Model of a Cross-Flow Heat Exchanger Introduction This article will develop a dynamic model of a cross-flow heat exchanger from first principles, and then discretize the governing partial differential equation with finite difference approximations. In a crossflow heat exchanger heat is transferred directly from the outlet air to the make up air through the separating walls of the heat exchanger. We use cookies to ensure that we give you the best experience on our website. Probably everyone wondering: “How does a crossflow heat exchanger work?”. For corrosion protection in wet and humid applications, all Heatex exchangers are available with powder coated framework and sealed joints. Suitable for close/open bypass exchanger section in connection with a cross-flow plate heat exchanger. (See the Thermodynamics, Heat Transfer, and Fluid Flow Fundamentals for a review of log mean temperature). Model P is a heavy duty, cross flow plate heat exchanger, specially designed for applications where high differential pressures occur. Cross flow. .contact, .contact-us{background-color: #7cc9da;}. Our products always comply with standards, perform according to (or even exceed) codes and specifications, and always live up to the highest technical standards. Subscribe to our Newsletter! For examples, cross flow exchangers are ubiquitous in heating, ventilating, and air conditioning (HVAC) systems not only as cooling and dehumidification coils but also as heating coils and air-cooled condensers. The internal and external air flows must therefore be completely separated.Even the slightest gaps or nooks have to be eliminated. Based on the same well-proven plate design as Model H, Model P’s efficiency is similar but offers a higher differential pressure resistance due to its extra strong aluminum plates. All rights reserved. Combined as modules, there is practically no limit.Suitable for air temperatures up to 300°C, important in the textile and film industries, detergent and PVC production and sewage-sludge drying. Model P is a heavy duty, cross flow plate heat exchanger, specially designed for applications where high differential pressures occur. Latent heat when moisture in the outlet air condensates on the recuperator. For ultimate corrosion protection, we recommend Closed Plate Cutting Edges which means that lacquer is run along the joints of the plates, covering the cutting edges found on epoxy coated plates. We are always here to help you! Cross Flow Heat Exchanger Calculation. It can easily be configured to comply with Ecodesign 1253/2014 requirements. The spacing between the plate often exceeds that in Counterflow plate models and this is important in industrial systems in which the air may be heavily contaminated. Efficiencies up to 65% for single units and up to 85% for two-step arrangements are typical. The fluids can also flow in perpendicular directions which is known as cross flow arrangement. For the highest corrosion protection, we recommend to add both Painted Framework and Closed Plate Cutting Edges. Share 0. Heatex air-to-air heat exchangers are designed to comply with all national and local building codes. A wide range of options including painted framework, epoxy coated plates and closed plate cutting edges will improve corrosion resistance and minimize air leakage even further. Keywords: Heat Exchangers, Cross Flow INTRODUCTION The cross flow exchanger is probably the dominant heat exchanger type in overall usage. We guarantee that there will be … With a global team of sales and technical support, Heatex responds quickly to inquires. Sizes vary between 200 and 1200 mm, while the spacings between the transfer plates vary between 2,0 and 13,5 mm. This model can be combined into various configurations to suit particular requirements. The two most common types of plate air to air heat exchangers are cross flow and counter flow heat exchangers. Model P is commonly used in the following applications. We offer a wide range of options to suit various application and performance requirements. The two main types are finned and unfinned tubular. The cross-flow plate heat exchangers (PWT) from Klingenburg are dimensionally stable and exceptionally impermeable and tough. Particularly in industrial applications such as process air systems, cross-flow plate heat exchangers must often withstand extreme temperatures. We hold several certifications for product and operation quality worldwide, including Eurovent, AHRI, EAC, RLT-Hygiene and ISO 9001.
