IMO Self Funding Energy Saving Scheme... ...quite simply, peace of mind.

Why do all energy saving initiatives seem to involve considerable upfront cost? Today that is no longer the case as IMO can deliver energy savings without any capital outlay. Traditional fans and pumps are hugely inefficient consumers of energy and the introduction of a Variable Speed Drive can deliver energy savings of up to 50% in many cases. Equipment such as air handling units, swimming pool pumps and extraction systems can all be controlled to deliver optimum performance but at a fraction of the cost. Lets work out how much electricity your motor could be costing you... Typical...

Want to know the technology behind saving energy with Variable Speed Drives? Energy can be saved if the motor speed matches requirements at any given moment in time. This applies in particular to centrifugal pumps and fans where the energy consumed is reduced by the cube of the speed. So, for example, a pump or motor running at half speed would only consume 12.5% of the rated power. Before calculating Energy Saving we need to consider; 1. What type of load is on the Motor? 2. How much energy can be saved? 3. What is the payback period? There are two types of load when calculating energy...

In these kinds of applications, torque (current) is proportional to the square of the speed and power is proportional to the cube of the speed, often referred to as “Cube Law”. However, speed reduction in these applications is usually achieved by “damping”, which is similar in concept to slowing a car by braking without releasing the accelerator. By using an inverter to electronically reduce the speed of the fan or pump and applying Cube Law, the power actually reduces by the cube of the speed change. It follows that a 20% reduction in speed equates to a 50% reduction in energy consumed...

Mechanical damping and flow control Many industrial and commercial fan or pump applications have been over specified in terms of motor size with mechanical damping or flow control systems introduced in order to achieve speed reduction. This type of mechanical control is highly inefficient as the motors run continuously at the speed required for the maximum delivery rate. This maximum speed is rarely required in practice. Additionally, the throttles and valves lose energy and cause high temperatures and vibration levels which can have a negative operational impact. Fan with Damper Control...

Now for the maths...calculating energy saving for Variable Torque Loads Step 3 : Step 1: Calculate the cost of the power you currently use (no VSD): Now for your energy saving per year: Savings = X - Y = Z Yearly cost = kW x T x C = X kW = Power used by motor T = Pump / Fan duty (hours) C = Power cost (£) per kW hour Step 2 : Calculate the cost of the power at a reduced speed (with VSD): 3 Yearly cost = kW x S x T x C = Y kW = Power used by motor (at full speed) T = Pump / Fan duty (hours) C = Power cost (£) per kW hour Y = Annual Cost (with VSD) Step 4 : Finally calculate your Overall...

Just some IMO customers that are saving energy and money thanks to Jaguar Drives. Jaguar Drives make a splash with energy saving swimming pools After reviewing and implementing all other ways to save energy and recognising that greater energy savings could still be achieved through pump and fan control in their Leisure and Spa facilities, the Thistle Hotel in Brands Hatch looked for a partner that specialised in this technology and turned to market leader IMO. The application was the re-circulating pumps for the main pool and spa pool running at a fixed speed (50Hz). The recommended...

Jaguar Drives make a splash with energy saving swimming pools (continued) Monitoring of the Spa pump with the Jaguar CUB attached showed that the power consumption over a 24Hr period was 26.14kWh equivalent to 40% reduction in the power used (figures based upon a 40Hz running speed during daytime and 30Hz during the evening). Over the same 24Hr period the average Amps used was 1.54 Amps in Variable Speed Operation, a 41% reduction in the power absorbed. Once the results were presented, Kevin Filmer, Site Property Maintenance Manager, had no hesitation in recommending the IMO Jaguar backed...

Jaguar drives mixers to €1000 per day energy saving. IMO is enabling a manufacturer of paper bleaching agents to fight back against rapidly rising energy costs. The manufacturer, Tielle S.R.L. is benefiting from savings of €1000 per day in production costs following the installation of 8 – 280kW IMO Jaguar drives to grinding mixers at its plant in North West Italy. “This application ably demonstrates the potential for energy saving with AC drives, outside of the normal areas such as pumps, fans and compressors,” said Del Tiwana, Drives and Automation Manager at IMO. “The rapid rise in the...
