Advertorial Mitsubishi Electric upgrades flagship


ventilation system for offices, schools, hotels and more


1


st June 2023 – Mitsubishi Electric launches the LGH-RVX3-E Lossnay Mechanical Ventilation with Heat Recovery (MVHR) system to provide clean and healthy air for every commercial setting.


We all spend an average of 90% of our time indoors, so ensuring the air inside buildings is fresh and clean is vital for our health. Dangerous pollutants like particulate matter and carbon monoxide are found indoors, and outdoor pollutants like nitrogen dioxide can also enter buildings from the outside. To combat their potential negative effects on health, equipping offices, schools, shops and more with the technology to support good air quality is essential. This is why Mitsubishi Electric has upgraded its trusted flagship Lossnay ventilation range, with the new LGH-RVX3-E system designed specifically for the UK’s commercial buildings. The units are designed to extract stale indoor air continuously and efficiently, and replace it with fresh filtered air from outside. With heat recovery, the system also minimises the amount of energy lost by recovering the heat from the extracted air and transferring it to the supply of fresh air. Hern Yau, Ventilation Product Manager at Mitsubishi Electric, said “The RVX3 Lossnay system is the next


iteration of our tried and trusted ventilation range. Maintaining good indoor air quality is imperative for commercial buildings, and the new units will enable every space to benefit. It can also work in conjunction with our Mr Slim and City Multi air conditioning systems to deliver fresh, energy efficient comfort”. The new system features a host of improvements to enhance performance, efficiency and versatility – all


while reducing running costs. The units can now be installed vertically for the first time, to allow for use in more spaces and make quality ventilation accessible to a wider range of buildings. Enhanced controls, with five different levels, allow for optimal efficiency, and fan speeds can also be adjusted in 5% increments to use less energy where possible and comply with Part L. The system is also designed to operate at ultra-low noise levels, to provide a comfortable environment for every building occupant, from office workers to hotel guests. A built-in automatic summer bypass also allows the RVX3 units to bring in fresh air from outside without recovering heat during hot weather, in order to reduce the risk of offices, gyms or other commercial spaces overheating. With 100% airflow still operating during bypass mode, the same volume of air is brought in – while staying cool. The addition of optional CO₂ sensors from Mitsubishi Electric also allows for automatic incremental fan control, and the sensors can optimise efficiency by managing the RVX3 system to react to the air quality. The sensors are directly powered by the RVX3 unit, so no additional power supply is required. The new system also offers patented fan coating for improved air quality, longer life and easier maintenance, and comes in a range offering air volumes from 150 m3/ h to 2,000 m3/ h to meet the need of every project specification.

AHU EVAPORATIVE COOLING CPD C


ondair is pleased to offer a CIBSE-approved CPD seminar on “Using humidifiers for evaporative cooling in AHUs”. The 45-minute presentation includes training on the psychrometrics of evaporative cooling, a review of the three main AHU strategies (direct, indirect and exhaust-air indirect), analysis


of three real-life case studies that employed these cooling strategies, and a comparison of the latest adiabatic humidifiers. Dave Marshall-George, UK Sales Director, comments, “A single adiabatic humidifier can provide up to 680kW of evaporative cooling to an AHU from as little as 0.3kW of consumed electrical energy. Their potential for delivering low energy cooling to an air handling unit is great and we frequently see this application being employed in modern AHU designs. This CPD is an invaluable chance for consultants and building designers to explore how humidifiers can be used in AHUs to take advantage of this low energy cooling method. The case studies detailed in the session provide a clear understanding, beyond the theory and physics, of the actual energy savings that can be enjoyed.” The seminar has been developed specifically for mechanical engineers and consultants. The presentation has been CIBSE-approved, therefore verified to be unbiased, up-to-date and technically accurate. All attendees will receive CIBSE points towards their continuous professional development (CPD) record. The presentation can be given in-house at a recipient’s office, typically over a lunch period with refreshments supplied by Condair, or online via a webinar platform. Bookings can be requested at www. condair.co.uk/CPD. The Condair Group is the world’s leading specialist in humidification and evaporative cooling, with energy efficient, hygienic and innovative technologies for commercial, industrial and heritage applications. Condair is represented in the UK by Condair Limited, which offers system design, manufacture, supply, installation, commissioning, maintenance and spares.

Unicrimp expands Q-Crimp accessories range


nicrimp, part of the Scolmore Group of companies, continues to expand its popular Q-Crimp range of cable accessories to provide installers with an increasing number of problem-solving products. The latest additions are a Green Earth Inspection Box and Hexagon Plain Driller Screws. Designed to house and help protect the connection to an earth point, the new Green Earth Inspection


Box forms part of the company’s growing earthing rods and components range which was first introduced in 2019. Measuring 100mm x 100mm x 50mm, it is constructed from PA66 to provide high mechanical strength and it is supplied complete with lid, fixings and a safety label. Joining Unicrimp’s extensive Q-Crimp range of fixings are the new Hexagon Head Plain Driller Screws.


These robust screws are designed to save valuable installation time with no need for pre-drilling. Because they are self-drilling this eliminates the need for a pre-drilled pilot hole as the screw performs the drilling, tapping and fastening in one action. They are available in a large range of sizes from 4.8mm x 13mm to 6.3mm x 50mm. The 6.3mm x 50mm comes in a pack size of 100, while all other sizes are in packs of 200. The Unicrimp catalogue which showcases the entire range of Q-Crimp accessories can be downloaded from the Unicrimp website - www.unicrimp.com – as well as from the Scolmore Group app.
