Armstrong has introduced new larger sizes of the Design Envelope Tango, a compact, low-carbon dual pump that ensures uninterrupted service, even during maintenance. The Design Envelope Tango includes two motors and two impeller assemblies in a single casing. Integrated valves can isolate one side of the pump for service, without interrupting flow or affecting occupant comfort. New sizes are now available with motors ranging from 11 to 30 kilowatts (15 to 40 horsepower) and are capable of serving applications up to 160 feet of pressure (2000 GPM).

Al Manar Building is a combined residential and commercial property located in Ras al-Khaimah, UAE. In a bid to reduce the building’s energy consumption and HVAC operating costs, energy service provider Active Sustainable Solutions enlisted the help of Armstrong for an extensive HVAC system upgrade.
In 2018, the HVAC system at a popular holiday resort suffered a series of failures and leaks, resulting in frequent downtime. An initial review determined that the existing pumps were the cause and had to be replaced. The review also noted that the pumps were oversized, which affected system efficiency. With the resort occupancy rates near 95% for most of the year, HVAC performance and reliability are crucial, so managers decided to go ahead with an upgrade.

Kevin Laidler, sales director for Middle East and Africa at Armstrong Fluid Technology, writes forTechnical Review Middle East, explaining how innovations in the HVAC sector can help data centres.
CAD (computer-aided design) drawings are digital files that house 3D & 2D models of physical objects. CAD files can include information such as geometric data, manufacturing data, material properties, and other data. CAD files are ‘to-scale’, meaning designers are able to create drawings in real-world dimensions.
Pumps can be grouped according to the method of displacement, the direction of fluid flow, orientation, and control capabilities. Major types of pumps include positive-displacement pumps, centrifugal pumps, and axial flow pumps.
In fluid-based HVAC systems an impeller is a component of the pump that creates pressure to maintain flow. In this post we’ll touch on key design aspects of impellers and present answers to the most common questions.
Armstrong Fluid Technology has formed a strategic partnership with Hysopt to bring customers new insights into HVAC energy saving options, harnessing state-of-the-art digital twinning.
Bringing together Armstrong’s extensive experience of installations worldwide, and Hysopt’s powerful technology, the new partnership will provide customers with more robust scientific simulation and verification of HVAC system energy and carbon savings than ever before.
Stephen Hart, spokesperson forArmstrong Fluid Technologyexplained: “Reliable information on the potential for improving energy efficiency of HVAC systems has never been more crucial. World events have brought a new sense of urgency.
It’s important for HVAC system designers to understand that the relationship between pump costs and pump size is not a simple straight line. As pump sizes increase, the costs for the equipment, related components and installation increase faster. The result is that a pumping system that serves an HVAC load using two small pumps is less expensive than buying and installing one large pump.
As facility managers, contractors and service professionals gain experience working with remote performance tracking capabilities for intelligent pumps, the HVAC industry is learning how valuable this type of subscription service can be. It seems that many customers originally agreed to the purchase of a performance tracking subscription service on the assumption that it would serve only as a security blanket, but would be mostly unnecessary. Based on the testimonial stories provided by customers describing service, maintenance and performance management scenarios, the subscription service has proven its value many times over. Examples detailing how remote performance tracking prevented a serious negative outcome, organized into categories, are presented below.
