Heat exchangers are a crucial piece of any application that involves heat transfer. In residential buildings heat exchangers can be found in radiant floor applications, pools, or domestic drinking water applications. In commercial buildings, heat exchangers are used for free cooling applications, chiller and heater loops and district energy. In Industrial and Process applications, heat exchangers are found in areas such as steam plants transferring heat from steam to water. They are also used in the refrigeration cycle as evaporators and condensers in chillers to save space and improve efficiency.

Power factor is a measure of how effectively electrical power is being used by a system. It is defined as the ratio of real power (measured in kilowatts, kW) to apparent power (measured in kilovolt-amperes, kVA). Mathematically, it is expressed as:

In a commercial potable water system, a booster pump plays a vital role, ensuring consistent water pressure and distribution. Booster pumps, typically installed in buildings with high-rise structures or complex layouts, elevate water pressure to meet the flow demands of fixtures and appliances. Like any mechanical equipment, booster pumps require regular service and maintenance to function optimally and avoid the possibility of disruptions in the water supply. In this article, we'll delve into the importance of servicing and maintaining booster pumps in commercial potable water systems.

Profile of Vertical Turbine Pumps

Vertical turbine pumps are specially designed to move water from an underground well or reservoir. Water enters the pump through a bell-shaped part called the suction bell. From there it moves into the first stage impeller, which raises the water's velocity. Vertical turbine pumps are typically used in applications where a flooded suction cannot be maintained. These include applications with underground water sources or below-ground tanks with an above-ground pump room.

Vertical in-Line centrifugal pumps are single-stage centrifugal pumps. They are designed for vertical installation with suction and discharge in-line, to provide a smooth flow of liquid through the system. This design aligns the driver, shaft and impeller with gravitational force, so the pumps experience minimal vibration. Vertical In-line pumps serve a wide range of applications, including commercial, municipal and residential high-rise buildings, large industrial premises and storage warehouses, offshore and remote facilities, airports and power stations. Because of their small footprint, they are excellent for industrial applications where space is limited.

This type of centrifugal pump uses a casing design that draws in fluid from the end of the pump and discharges fluid out the top. End suction pumps are almost always single stage pumps, which means they use only one impeller.

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:
