The power solutions division of BANZ Trading & Contracting focus on providing the local customers in Bahrain with different products and services in relation to energy and power saving and monitoring.


Power quality analysis

Identify the origin and source of the disturbance or conditions that leads to poor power quality like dips and swells, spikes, surges, momentary outages, sags etc, that results in malfunctioning, premature failure and sudden shutdown of computers and other electrical equipment and provide an effective solution.

Harmonic analysis and calculations

Harmonics or distorted steady state electrical current waveforms are caused by single phase non-linear loads in office buildings and three phase non-linear loads in factories and plants. The harmonic analysis involves the use of predictive computer software to identify potential problems and resolve mitigation solution.

PF analysis

Power factors below 1.0 require a utility to generate more than the minimum volt-amperes necessary to supply the real power (watts). This increases generation and transmission costs. For example, if the load power factor were as low as 0.7, the apparent power would be 1.4 times the real power used by the load. Line current in the circuit would also be 1.4 times the current required at 1.0 power factor, so the losses in the circuit would be doubled (since they are proportional to the square of the current). Alternatively all components of the system such as generators, conductors, transformers, and switchgear would be increased in size (and cost) to carry the extra current. Utilities typically charge additional costs to commercial customers who have a power factor below some limit, which is typically 0.9 to 0.95.

Power factor study is carried out to observe the loading pattern and the conditions of poor average power factor maintained in the plant and to suggest remedial measures to maintain healthy average power factor.


Automatic power factor control panels

They are made up of a combination of capacitor steps connected in parallel in order to improve the PF of an electrical system. Switching on and switching off of each step is done by a power factor controller which is a part of the panel.

Active and passive harmonic filters

There are two main types of harmonic filters used for VFDs – passive and active.

Passive filters typically filter a single drive; meaning a separate filter is required for each VFD in a multiple VFD system. Passive filters are usually most effective when running at close to their rated capacity, so need to be sized carefully to suit the load. Active filters monitor the current for a complete installation and inject currents to mitigate harmonics as required – so that a single active filter can be used for filtering of many VFDs of varying sizes.

PQ meters

Installed in any 11KV systems to measure flickers, harmonics, voltage, power, reactive power, energy, current etc.  It is connected to a software for the collection and analysis of data.

Energy meters

These are used for power monitoring and energy management for all types of electrical networks (small and large consumers).


What is an Air barrier?

The Enershield air barrier creates a “virtual door” by re-circulating ambient air and directing it across an opening in a laminar airflow to create up to a 90% seal. This “invisible” door seals the opening and provides an effective “environmental separation” and stops the transfer of temperature, humidity, dust, odours and insects. With just a draught of air creating the barrier, vehicles and pedestrians can pass without obstruction.

Air Barrier v. Air Curtain

Air barriers should not be confused with a heated warm air curtain, whose primary design objective is to provide warmth at a retail doorway. Without a proper seal over an open door, your expensively heated or air-conditioned air, along with the warm blast from a typical heated air curtain is immediately conveyed to the outside. 

A typical 5kw air curtain operating 8 hours per day, 5 days per week will consume £1,000 of energy per annum. In the same conditions, an Enershield air barrier will consume £60 of energy per annum. 

How the air barrier works

Enershield Air Barriers create an effective seal on the doorway by re-circulating the facility air in a laminar (smooth) flow across an open doorway. The kinetic energy in the moving air generates a barrier, like a waterfall, that prevents leakage of air between two areas with different pressure and climate. The more laminar this air flow, the harder it is for outside air to penetrate the barrier.
