In a number of countries, such as Indonesia, it is common for a device such as a POWEREES to be referred to as an inverter.  Technically speaking an inverter is a general-purpose device that converts direct current (DC) to alternating current (AC), whilst a POWEREES is used to adjust the motors power supply to control the motors speed and torque.  In controlling the motor the POWEREES will actually use an inverter in the process, and can be referred to as the output part of the POWEREES drive. 

Businesses are charged electricity based upon the kWh consumed from their electricity supplier.  By installing a POWEREES drive, this power consumption is reduced by ensuring that your electrical motor only uses the power it needs to operate at its optimum level.  This reduction in power consumption translates directly into lower power bills.

In 1995 at the UN Climate Change Conference (COP21) 196 countries adopted The Paris Agreement with the aim of limiting temperature increases to a maximum of 1.5°C above pre-industrial levels.   To do this greenhouse emissions must peak before 2025. 

Greenhouse gas emissions include carbon dioxide (CO₂) produced in the generation of electricity, particularly with regards to fossil fuel sourced power.  Reducing the amount of kWh consumed directly reduces the amount of power needed to be generated and in turn reduces the amount of CO₂ released.  As an example, for an average 8kW motor operating 12 hours a day, CO₂ emissions of over 10t can be saved every year by installing a POWEREES drive.

EES will install a data logger on the electrical motor that our POWEREES drive is connected to.  Amongst other things, this will accurately measure the power used by the motor in kilowatt hours (kWh).  This data is provided at the end of each month but can also be accessed in real time through our SMARTEES platform.

Prior to installing a POWEREES drive , EES will install a data logger on your operating motor(s) and measure the power being drawn by the motor (kW) and the power consumption (kWh). This is the base line for that motor. After installation the data logger will remain installed and will continue to measure the kW and kWh for the electrical motor with the POWEREES working. This difference between the two readings is the verified power consumption as a result of installing the POWEREES.

Whilst the data loggers are primarily used to measure the power consumption of the pool pumps, they can be installed on any circuit.  Clients have used this tool to confirm the accuracy of their power bills, or to even assist in allocating power costs between shared offices or where separate businesses may use a single power meter.

No.  In fact the POWEREES drive is built with features that help protect your pumps from faults and potential brown outs.  In addition, by having your pump work more effectively, repair and maintenance costs will be reduced and the life of your pump extended.

The reduction in power and the reduction in flowrate are not equal.  By installing a POWEREES drive there will be a small reduction in waterflow, but nothing that will adversely affect the pool turnover rate.  In fact, by installing a POWEREES drive your pump will work the way it was designed to.  A slower flow rate reduces water flow resistance and adds to improving filtration efficiency, resulting in crisper water.  The EES team work with our partners to ensure that the pools operations are not impacted, whilst at the same time saving on power consumption and therefore costs.  Pool features such as fountains and waterfalls will continue to work in exactly the same way.

Yes it will – in a positive way.  By installing a POWEREES drive your pool pump will work the way it was intended, meaning improved filtration and cleaner, crisper water.

A pool system is made up of 3 separate elements – pump (circulation); filtration (purification) and chemical balance.  The POWEREES drive only focuses on the pump element, and helps the pump work more effectively.  Green water is normally a sign of algae meaning that in most cases if the pool water has turned green, it’s one of the other 2 elements that have an issue. EES has seen where installing a POWEREES drive it has highlighted issues such as poor chemical balance or improperly maintained sand filtration systems.  In 99% of the cases, any deterioration in water quality is a result of 1, or sometimes both, elements.

It can, however it must be remembered that every motor is different, even if they are the same size and from the same manufacturer.  Before installing a POWEREES drive on multiple pumps, the EES team will work with your operations team to understand how best to install the POWEREES so as to gain the greatest power savings without comprising on your operations.

Our POWEREES drives are IP66 rated, meaning total protection against dust and strong jets of water.  Built with tough polycarbonate, they are specifically designed to withstand degradation by ultra-violet (UV) light, greases, oils and acids.  Able to operate in environments of up to 95% humidity, space is generally the only potential limitation on where a POWEREES drive can be installed.

The POWEREES drive comes with motor protection features.  If the POWEREES drive detects a fault within the power supply – such as a dropped phase – then the POWERees will stop the supply of power to the pump in order to protect the pump from damage.  Where this happens, clients should request assistance from EES to investigate the reason for the shutdown and address the potential harmful cause rather than requesting to bypass the POWERees, as ultimately without the protection of the POWERees you are risking more damage to your pump, which will potentially lead to higher costs.

No, in fact by installing a POWEREES drive it will help reduce maintenance costs.  During start up the POWEREES will eliminate in-rush current, reducing  heat and stress on a motors windings, as well as detecting problems early and notifying operators before problems lead to costly repairs and downtime.   

The POWEREES range covers both single and 3 Phase motors, meaning that there are very few motors that EES can’t help with.  For single phase motors our drives are limited to 10.5A whilst for 3 phase motors we can supply for motors all the way up to 110kW in size. 

POWEREES is designed with versatility in mind, making it suitable for installation on a wide range of motor-driven equipment.  This includes devices such as pool pumps, extraction fans, fresh air systems and water distribution pumps.  The POWEREES range covers both single and 3 Phase motors, meaning that there are very few motors that EES can’t help with.  For single phase motors our drives are limited to 10.5A whilst for 3 phase motors we can supply for motors all the way up to 110kW in size.  By optimising motor performance, POWEREES helps reduce energy consumption and operational costs across various applications, delivering tailored efficiency benefits based on the device in use.

Every motor is different, so it is impossible to give an accurate prediction on exact savings until the POWEREES drive is installed.  In general EES won’t recommend the installation of a POWEREES drive unless we believe we can achieve greater than 40% power savings for a single phase motor and 50% power savings for a 3 phase motor.  In some instances it has not been uncommon to see savings of 65% and greater for pool pump motors.  With over 15 years of experience in installing and programming equipment such as the POWEREES drive you can rest assured that EES will assist you in maximising your savings whilst not compromising on performance.
