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).

Design Envelope Tango is a compact solution that com

Harmonics are voltage or current waveforms that are distorted from their fundamental sinusoidal shape. They are multiples of the fundamental frequency (50 or 60 Hz) and are generated by non-linear electrical loads. These are loads that draw current in abrupt pulses rather than in a smooth sinusoidal manner. Common sources include:

What is the main cause of water hammer?

In commercial plumbing installations, which often incorporate large diameter pipework and pumped systems, water hammer can be a single destructive event that occurs when a pressure wave rapidly propagates through the pipework. The magnitude of the incident and the reflected pressure waves can sometimes exceed the rated operating pressures of components within the plumbing system. Surges can typically exceed 1.5 times the normal system operating pressure.

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.

Pumps that are designed and approved for fire suppression systems can be grouped into four major categories based on configuration.

Design Envelope Fire pumps are designed, assembled, and tested to meet the code requirements of a Self-Regulating Variable Speed Fire Pump Unit, as described in NFPA 20 – 2019 edition. Design Envelope Fire pumps are factory-built, integrated fire pumps consisting of a Vertical In-Line pump, driver, and variable speed control unit. They’re configured to maintain a set pressure until the maximum power draw is reached, while modulating pump speed to control to meet limits on pressure or suction.

Design Envelope 6800 boosters are pre-assembled, compact systems. With Vertical Multi-stage pumps, these systems are energy-efficient and require minimal maintenance for reliable, long-term occupant comfort.
