ANDRITZ launches PrimeDry HotAir Box
ANDRITZ has developed the PrimeDry HotAir Box , an innovative solution that enables tissue producers to reduce energy consumption and CO 2 emissions while increasing machine efficiency . Designed to address the energy-intensive nature of tissue drying , the PrimeDry HotAir Box recovers a
Daikin Applied launches glycol-free chiller option
Going glycol free can improve heat transfer efficiency and , therefore , performance while also reducing running costs . While glycol is useful in applications where freezing is a concern , it can be an environmental or health hazard due to its toxicity and can degrade over time which causes reliability problems .
Choosing a glycol-free option can also be a regulatory requirement in some regions and for sensitive environments like food processing , pharmaceutical manufacturing , or data centres . So , Daikin has developed a “ closed loop ” system that delivers an efficient solution for applications where avoiding the use of glycol is
portion of the hot , wet exhaust air from the drying hood for reuse in the process . The exhaust air is separated after the air-to-air heat exchanger , filtered , and evenly blown onto the tissue web ahead of the suction roll . The temperature increase reduces the water viscosity of the web , resulting in higher dryness after the press . In this way , the PrimeDry HotAir Box contributes to a significant reduction in the total energy required to achieve the final paper dryness or to a significant increase in production . The PrimeDryHotAir Box includes a retraction system allowing for maintenance , tail threading , and cleaning operations . The filter is cleaned automatically at regular intervals . It is compatible with any suction press configuration , the system is suitable for new installations and rebuilds .
preferred . It is the latest addition to the company ’ s TZ D air-cooled free cooling chiller range which employs the latest technology to deliver top performance across a wide range of capacities from 180 to 2150 kW . These free-cooling products are a popular solution for comfort , process , and critical cooling applications where the outdoor ambient conditions are between – 20 ° C up to + 55 ° C and the supply water temperature is – 12 ° C up to + 30 ° C . The new EWFH / S / D-TZ D models are designed with a fully integrated free cooling system and the controls enable free cooling operation when the outdoor air temperature is low enough to cool the fluid returning from the system to the chiller . The range is available with a choice of three refrigerants : R-1234ze , R-513A , and R-134a , and in four efficiency levels based around its single screw compressor design .
Metso launches a renewed Metso Plus concept
Metso launched its Planet Positive approach as a concrete answer to tackling the sustainability challenges of its customer industries . Ever since the products and services included in Metso ’ s sustainable portfolio have been important to differentiate the company . To date , Metso has over 100 products in its portfolio of sustainable products . These products are demonstrably more energy or water efficient than the industry benchmark or Metso ’ s previous generation products . They provide added benefits to the customers , helping them cut their
CO 2 emissions , reduce pollution to land , air , and soil , increase circularity and safety , and improve productivity . To comply with the proposed changing EU legislation and to emphasize the focus on supporting the customers with their key challenges , Metso is renaming its Planet Positive offering to Metso Plus . Similarly , the former Planet Positive label will change and have a new design . Metso Plus builds on the company ’ s extensive expertise and the reliability of its products and services supporting customers from pit to port . The offering marks Metso ’ s commitment to go beyond and exceed expectations - by continuously enhancing technologies and providing additional sustainability benefits for both customers and the environment . Metso ’ s R & D initiatives aim to expand this portfolio .
Graham plans for advanced cryogenic propellant testing facility
Graham Corporation ( Graham ), a global leader in the design and manufacture of mission critical fluid , power , heat transfer , and vacuum technologies for the defense , space , energy , and process industries , its plans to construct a stateof-the-art cryogenic propellant testing facility in Florida , near its P3 Technologies , LLC subsidiary .
Leveraging Graham ’ s longstanding expertise in the cryogenic and space launch industries , this new facility will help to meet the increasing demand for efficient , scalable testing solutions in key markets , including Space , Defense , New Energy , and potential applications in the medical field .
The facility will offer a cost-effective , timely alternative to existing testing centers , which often prioritize flagship programs and leave other critical programs with limited options . This new facility will enable liquid hydrogen ( LH2 ), liquid oxygen ( LOX ), and liquid methane ( LCH4 ) testing at pressurized , sub-cooled , or saturated conditions , and is ideally suited for testing pumps , components , fluid management systems , and combustion devices . By expanding Graham ’ s capabilities in cryogenic propellant testing , the Company aims to better support both current and future customer programs , adding agility and depth to its testing services in response to diverse and evolving program requirements . The project will be executed over the next year , with initial tests anticipated to begin by mid-2025 . The facility is projected to achieve a cash payback period of approximately two to three years and deliver an internal rate of return exceeding 20 %, representing a strategic investment in Graham ’ s future . www . heat-exchanger-world . com Heat Exchanger World December 2024
