Daikin Altherma 4 on R454C and R290
The T21 brings new energy to energy efficiency
Efficient heat transfer can save millions of tons of CO 2
. With Alfa Laval ’ s new T21 plate heat exchanger , customers can boost their sustainability journey , reducing
CO 2 and energy consumption . When it comes to combating climate change and meeting the goals of the Paris Agreement , energy efficiency has a vital role to play . Over the next 20 years , increased efficiency could account for more than 40 percent of emissions reductions . And the solutions to enable these energy efficiency improvements already exist . Alfa Laval ’ s new T21 plate heat exchanger enables energy efficiency across most industries and will
become one of the main drivers within the plate heat exchanger portfolio . It ’ s more compact , more convenient , and more adaptable . Thanks to several plate materials and pressing depths that it can now offer efficient heat transfer to even more industries . “ We are launching the new T21 GPHE , which is replacing the T20 one of the most popular Alfa Laval products in our range ,” says Julien Gennetier , President , of BU GPHE . “ Now we are working to push even further with the T21 . Thanks to several plate materials and pressing depths we can now offer efficient heat transfer to even more industries .”
Daikin is about to launch its latest range of Altherma 4 heat pumps with versions using R454C and R290 ( propane ) refrigerants . Daikin says the new range of airto-water heat pumps is a response to REPowerEU , the European Commission ’ s plan to make Europe independent of Russian fossil fuels , and to Europe ’ s HFC phaseout . R454C with GWP 148 is a mixture of A2L R32 and 1234yf . According to Daikin , the use of this lower GWP refrigerant offers a wide range of installation options , making it suitable for use in a variety of residential building types across Europe . R290 , better known as propane , is an A3 refrigerant with a GWP of just 3 .
The first series , the Daikin Altherma 4 H Standard , will be launched in 2024 in sizes from 4kW to 8kW . The heat pump with an operating range down to -25 ° C is reportedly suitable for various European countries and can be used for various types of heat distribution systems , from underfloor heating to radiators . Outlet water temperature up to 65 ° C . The second series is the Daikin Altherma 4 H Quiet , powered by R290 , with a power of 8 , 10 , and 12 kW . As the name implies , the main feature of this series is the particularly low noise level . Producing water temperatures up to 70 ° C , it will be available in both single-phase and three-phase versions .
Kaltra offers reengineered Turbocor-based chillers
With the launch of Powerstream Turbo II water-cooled chillers this month , Kaltra extends and improves its portfolio for IT- and process cooling applications . In terms of energy efficiency , new chillers are a step ahead of mainstream units available on the market , far exceeding seasonal efficiency levels of EcoDesign 2021 specification . When introduced in April 2018 , the Powerstream Turbo has previously been available in capacities from 300kW to 4.5MW with R134a and R1234ze refrigerants , with R513a , added later .
The new range , Powerstream Turbo II , will be launched with R1234ze in capacities of up to 2MW and extended to 4.5MW later in 2023 .
Inheriting all advantages of its predecessor , the Powerstream Turbo II operates with supply water temperatures of up to 25 ° C and evaporator deltas up to 15 ° C , condenser water temperatures of as high as up to 55 ° C , and features lower noise emission levels ( -15dB ( A ) in lineup average ). Powerstream Turbo II ’ s set of options includes integrated sequence management with a dynamically selectable master unit and resource priority management , fast restart , refrigerant leak control , and built-in energy analysis software .
Bendel Tank & Heat Exchanger stainless steel storage tanks
Bendel Tank & Heat Exchanger recently shipped a pair of custom fabricated stainless steel storage tanks to a Minnesotabased food & beverage industry customer . Storage tanks utilised for the storage and transportation of food and beverage products are typically made of stainless steel , chosen for its durability , corrosion-resistance , and its ease of cleaning .
Bendel has the expertise to design and manufacture custom above-ground vertical and horizontal stainless steel storage tanks to meet all process and industrial manufacturing needs . The storage tank fabrication process starts with the design and specifications of the tank , which are typically provided by the customers . The in-house engineers often work with the customers to achieve optimal designs .
Following the design and engineering stage , stainless steel is cut to size and shaped using specialised equipment , including water jets , lasers , or plasma cutters . Tank components are then welded together by expert team of AWS-certified welders , utilising specialised welding techniques which can include TIG ( Tungsten Inert Gas ) welding or
MIG ( Metal Inert Gas ) welding . Once welding is complete , the tank is polished and cleaned to remove any surface impurities or contaminants . The last step is the installation of any required components such as valves , gauges , and other fittings which are attached to the tank using specialised welding and / or bolting techniques .
