LPW Technology

The Background

LPW is headquartered in Widnes, UK with additional processing operations in Pennsylvania, and is renowned for its metal powders and management, storage and monitoring systems. Those materials are developed for powder bed fusion processes and optimised to the specific machine type, whether it be EOS, SLM Solutions, Concept Laser, Renishaw, 3D Systems, Trumpf, Arcam, and so on. In more recent times, the company has stepped up its embrace of automation and end-to-end solutions, bringing to market its PowderLife portfolio, which ensures powder can be properly managed and assured.

The Challenge

The project comprised of providing a detailed design, process development, coordination, supply, installation, commissioning and setting to work of a cooling system incorporating all Mechanical and Electrical Services installation, for a cooling capacity of 650kW and for the unit to be designed with a +32℃ ambient temperature.

The Solution

Following our design options BRS recommended a bulk glycol system in order to meet the 650Kw cooling demand and to ensure maximum efficiency and continuous efforts to improve energy efficiency, save water and reduce noise adiabatic cooling was utilised, BRS at this stage have not performed any formal heat load calculations and based the design using the following design criteria…

The Specification Included:

  • Requested Duty:  650Kw
  • Cooling Medium:  Water/Glycol
  • Glycol Anti-Freeze:  22%
  • Cooling Medium Flow Rate:  11.20l/s
  • Flow Water Temperature:  +28℃
  • Return Water Temperature: +47.59℃
  • Reduced Air on Temperature:  +22℃
  • Outlet Air Temperature:  +39.01℃
Process engineering systems
Process engineering
  • 1 off Adiabatic Air blast cooler – Model: 9.A.FB.VEBI.CCF
  • Centrifugal inverter glycol pump packs
  • Mains electrical supply installation
  • Stainless steel Mapress glycol primary and secondary flow and return ring mains, thermally Insulated
  • Glycol cooling header and buffer tank
  • Control and control strategy system with integration to atomiser control circuit
  • De-ionised water system and pressurisation systems

The Result

Highly intelligent and efficient cooling system to provide demand cooling during the atomising of solid titanium steel rods which requires automated start up and shut down control procedures, With confidence in the cooling capacity and system installed this allows the experimental process to be tested and developed and the project team to focus on developing the next phases of the business.
