Here are the top five features of the Revolution SLC EC:

1. Future-proofed

The evolving nature of the ventilation industry means that products are frequently at risk of not being compliant, with manufacturers under constant pressure to deliver in-line with the latest legislative changes.

The Revolution SLC EC has been developed to ensure compliance with legislation likely in 2021, and should easily pass any regulations that are anticipated before 2030. In a sector that is vulnerable to sudden change, it provides an assurance of continuity for those tasked with delivering ventilation solutions.

2. Lower running costs

A defining feature of the new fan is the transition from an AC motor to a low energy EC motor. This has a number of benefits, not least the reduction in running costs associated with the unit.

Complete with high-quality impeller blades and an increased blade chord and twist, the Revolution SLC EC achieves running cost savings of up to 20%, helping to reduce overall energy consumption compared to previous models. It also makes ventilation management far easier for the end user, due to built-in control for setting fan speed during commissioning and operation.

3. Greener credentials

Aside from the lowering the running costs, the Revolution SLC EC also significantly reduces CO2 emissions. This is particularly important with the current trend towards improving the environmental impact of buildings, putting pressure on contractors and facilities managers to deliver effective products. The efficiency of the new fan is ideal for decreasing energy consumption and ensuring compliance with the latest ecodesign regulations.

4. Versatility

The range of applications that it can be used in marks the Revolution SLC EC as a versatile ventilation option. It’s designed to operate in a wide range of locations, including sports centres, warehousing and stores, factories, and commercial kitchens.

It’s also available in a range of sizes, from 315mm to 630mm, ensuring that the benefits of the long-cased axial fan can be enjoyed in a wide range of applications.

5. Easy installation

The host of benefits associated with the Revolution SLC EC are underpinned by the straightforward installation and maintenance processes. A fitted IP55 terminal box allows the fan to be positioned conveniently to incoming electrical inputs, and the complicated task of having to install a commissioning device is removed because it’s located within the fan itself.

Contractors are able to pass on these savings to their customers, and in an industry fraught with uncertainty, the innovative Revolution SLC EC provides peace of mind for those tasked with delivering ventilation strategies.

1. Concentrate

Poor indoor air quality (IAQ) has been shown to have a negative effect on the attention span of school children, leading to a noticeable drop in concentration when CO₂ levels are high. There are also longer-term impacts on health, which can include headaches, coughs, and irritation of the eyes, nose, throat and skin.

Mechanical ventilation is the most effective way to provide fresh, filtered air into classrooms. CO₂ sensors detect changes in pollution levels, automatically adjusting fan speed to ensure that air quality is reliably controlled, and drowsiness doesn’t set in.

2. Control

Managing the comfort levels within a school can be challenging, and many opt for natural ventilation as a way to improve the IAQ. However, this can become an issue in colder months, when cool air flows from outside, into the building, placing a huge amount of strain on a school’s heating system. It is also reliant on the quality of the surrounding outdoor air with very little control over the flow of air coming in to the building. This is where mechanical ventilation comes in, which avoids these issues by providing schools with much greater control over the temperature and quality of air flowing into classrooms, thus increasing the comfort and wellbeing of occupants.

3. Cost-effective

Schools are tasked with balancing occupancy and comfort levels, all while considering the potential financial burden of providing good indoor air quality. Heating bills – especially in a climate as temperamental as the UK’s – can become very large, very quickly. The prospect of having to decide between thermal comfort and clean air for schoolchildren is a chilling one, which is what makes mechanical ventilation such a good option.

Combining thermal energy recovery with added thermal treatment for when it’s needed can help to reduce energy expenditure. Thermal energy recovery units are able to recover heat from warm air inside the school, and use it to raise the temperature of incoming air. Adopting an intelligent ventilation strategy that uses indoor air quality and energy recovery management devices, such as the KINAIRTICO controller, helps to maximise energy savings.

4. Compliant

Recent updates to the Building Bulletin 101 (BB101) bring stricter guidelines to air management in schools, especially when it comes to overheating in summer months and CO₂ levels in teaching spaces.

Between the 1^st May and 30^th September, there should be no more than 40 hours when the temperature is 1⁰C above the allowable maximum. For CO₂, the daily concentration in an occupied space must be less than 1500ppm for natural ventilation, and for mechanical ventilation it should be under 1000ppm.

Having a ventilation system which can adapt to fluctuating requirements is absolutely crucial for schools, and mechanical ventilation is the most reliable way of achieving this.

6. Clear and easy set-up

For the sake of minimal disruption, schools often conduct building and refurbishment works outside of term-time. Therefore, any mechanical ventilation must be installed quickly and easily, in order to be ready in time for students returning.

Elta’s PREMA range of energy recovery units are amongst the lightest on the market, which makes them easier to install than many other mechanical ventilation units. With quick set-up times, and intuitive controls once up and running, mechanical ventilation units are an important asset for schools in the provision of clean air and thermal comfort to their students.

The Intelligent Demand Control Diffuser adjusts ventilation levels according to demand by measuring CO₂ levels and adapting to suit occupancy patterns. It has been aerodynamically designed to provide optimum ventilation effectiveness, as well as being easy to install and commission.

With no other method available on the UK market that offers such a fine-tuned automatic ventilation control, the solution also stands out through not being limited by building size or layout. The diffuser works in a constant pressure control system incorporating technology from other brands within the group including the Demand Control Ventilation fans from Elta and Air Handling Units from Air Design. Ultimately, it encourages the use of low pressure systems, further optimising energy usage and lowering building energy consumption.
