Welcome to Murphyfinnedtubes!

The AHR expo 2020 promises to be the biggest congregation of HVAC professionals in the world, which is a very exciting prospect for those looking to make new connections, find better suppliers and upgrade their current HVAC systems. However, with so many options and vendors showing their wares, it can be overwhelming and it is important to go into AHR expo 2020 with a game plan to maximize your time.  With the following guidelines you will be able to efficiently manage every aspect of your experience. Don’t Ignore The Basics While it can be exciting to see demonstrations of brand new technology that looks destined to change the HVAC world remember that most of the time these out-of-the-box ideas die after a few years. What never falls out of fashion is the tried and true core components of the HVAC industry and it is in these areas where incremental progress can lead to vast differences in your life. The humble heat exchanger might seem as if it hasn’t been upgraded in dec...

Spiral plate heat exchanger improved heat transfer, actually also is in order to improve the efficiency of the spiral plate heat exchanger and the ability to, first of all, we actually is to pay attention to, and also reduce the thickness of the plate thickness plate design, and on its corrosion resistance would have no relation, is associated with the bearing capacity of spiral plate heat exchanger equipment. If the plate is thickened, the pressure capacity of the heat exchanger can be improved. , spiral plate heat exchanger on the plate if using combination of chevron plate, this time also is to pay attention to each other with respect to its adjacent plate upside down, on the corrugated will have to contact each other, at this point, we also is to pay attention to, actually this time also can form high density, homogeneous distribution of fulcrum, plate Angle away L and its edge sealing structure has gradually improve, make the heat exchanger equipment has the very good bearing cap...

Spiral plate heat exchanger equipment can be broken down, mostly because of quality problems. Compared with the heat transfer surface of other heat exchangers, the heat transfer surface of this heat exchanger is quite thin, that is, 0.5mm, and the allowable high corrosion degree is 0.05mm/ year. The material of common spiral plate heat exchanger equipment usually USES alloy material (304 or 316), 304 is the low cost of austenitic stainless steel, has the ability to resist corrosion to a certain range of organic matter, but the ability to resist hydrochloric acid and sulfuric acid is weak. Spiral plate heat exchanger equipment can be broken down, but also because of its own maintenance problems. Spiral plate heat exchanger equipment is an important component of heat exchange technology in process industrial equipment. The resilient gasket that seals between the various helical fins is a vulnerable part and also an easily aged part under natural conditions. Its service life has an impo...

When selecting spiral plate heat exchanger equipment, Murphy experts suggest that users should specify the general requirements for heat exchangers, including the specific requirements for the selection of spiral plate heat exchanger equipment should have thermal performance, including the flow of fluid on each side, inlet and outlet temperature, heat transfer, etc. Attention should also be paid to the type of fluid and the fluid's thermophysical properties, physical and chemical properties (such as fouling, corrosion, danger, and impurities, etc.). Clarify the operating conditions, working pressure and environmental conditions of spiral plate heat exchanger equipment; Next, it is necessary to pay attention to the clear technical and economic requirements, such as heat exchanger material, price, weight, size, flow resistance and fan and pump power, operating life, maintenance and cleaning requirements, maintenance cycle, transportation and installation restrictions. www.murph...

Plate spacing in spiral plate heat exchanger, the ripple height or the gasket groove depth is 25% higher than normal, so that can prolong the heat exchange between the liquid on the plate, so that will make heat transfer more sufficient, increases the cold and hot medium temperature, at the same time, it can improve the thermal efficiency, small heat transfer temperature difference is only 1 ℃. Spiral plate heat exchanger heat transfer coefficient is higher, has the characteristics of high efficiency and energy saving, because the liquid into the heat exchanger plate, between turbulence is very developed, the formation of turbulence and support the contact between the plate and there will be more close relationship, many support contact will also makes heat exchanger heat transfer capacity was improved, bearing capacity will be strengthened. Murphy spiral plate heat exchanger plate stiffness is better. Since the thickness and width of the gasket (that is, the volume) on the much larg...

Spiral plate heat exchanger devices used by the plate on both sides of seal groove, of course, there will be a continuous distribution side, and, in general, actually a side is straight, the other side also is irregular corrugated side. The continuous side edge in the center will provide strong support to the gasket, but the corrugated side edge of the plate and the corrugated side edge of the gasket will also realize just biting each other, which will make the gasket more firmly fixed on the plate, not easy to slide out of the seal groove due to pressure fluctuations and other reasons. The plate used in the helical plate heat exchanger equipment, Murphy experts use new technology and make non-bonding gasket appears to be very easy to install, and the ridgelike projection on the outside of the gasket just matches the groove on the back of the other plate, so that the whole plate group can get stuck when clamping to avoid dislocation. www.murphyfinnedtubes.com Spiral plate heat e...

The application of spacing column in spiral plate heat exchanger is, simply speaking,  refers to the small cylinder or cuboid welded on the spiral plate. The function of spacing column in spiral plate heat exchanger is to keep the spacing of the spiral plate to one. At this time, the rigidity, stability and strength of the spiral plate can be improved. Most of the spiral plate heat exchanger manufacturers use the fixed distance column is made of the car, because the different center of the car caused by the beating of its section center residual boss, in the spiral winding plate surface damage is very large, and reduce the pressure capacity of the cylinder body. Murphy adopted the blanking and shaping process to effectively solve the problem and greatly improve the production efficiency. When it comes to spiral plate heat exchanger equipment, we should pay attention to the middle of Japan and Sweden, carbon steel distance column extruded by wire, the surface after phosphating tre...
