Lossnay LGH-RVX3-E FRESH AIR ENERGY RECOVERY SYSTEM The Lossnay LGH-RVX3-E Mechanical Ventilation Fresh Air Heat Recovery (MVHR) systems are designed to supply clean, fresh air into any commercial building, whilst simultaneously extracting stale air, ensuring good indoor air quality for occupant wellbeing. These units are also able to recover valuable heat and latent energy from inside the building, maximising energy efficiency and reducing running costs. Key Features Maximise Heating and Cooling Efficiencies Through its unique energy recovery core, the Lossnay LGH-RVX3-E range can recover up to 88%*1 of the thermal exchange efficiency from stale outgoing air, and transfer this to pre-warm (or pre-cool) incoming fresh, filtered air being supplied into commercial buildings. For example, in winter a building that has an inside temperature of 20°C and 4°C air outside, the incoming fresh air can be warmed to over 18°C by transferring through a Lossnay Ventilation System and benefiting from the efficient energy transfer process. The building’s air conditioning systems no longer have to work as hard to maintain desired indoor air temperatures. * 1 LGH-25RVX3-E on lowest fan speed for winter conditions Optimise Indoor Air Quality Lossnay LGH-RVX3-E models are equipped with a treated paper core to recover total energy (sensible and latent heat) from the outgoing stale air to pre-warm (or pre-cool) incoming fresh air. This total energy recovery allows buildings to maximise efficiencies whilst maintaining healthy CO2 and humidity levels for better indoor air quality. Improved Airflow Range The LGH-RVX3-E range offers upgraded variable air control for finer, more effective ventilation. Default fan speed values of both supply air and exhaust air can be adjusted in 5% increments (between 25% and 100%) in order to match required airflow rates with greater precision.

Low Noise Design Offering whisper quiet operation across all fan speeds (starting from 17dBA*2), the LGH-RVX3-E range is the ideal solution for meeting stringent sound level requirements. *2 LGH-15/25/35/50RVX3-E on lowest fan speed. Improved External Static Pressure External static pressure has been improved by up to 35Pa / 41%*3 compared to previous models, increasing both the flexibility of duct work design as well as the number of applications that can be catered for. *3 LGH-25RVX3-E model on highest fan speed. Dual Barrier Coating The patented and world’s first Dual Barrier Coating from Mitsubishi Electric prevents dust and dirt from accumulating on the interior of the Lossnay unit; helping to keep it clean for optimal performance all year-round. Keeping the heat exchanger clean is important for both home comfort and efficiency. Not only can dust and dirt build-up typically create unpleasant odours, it also significantly impairs heat exchanger efficiency. Dual Barrier Coating prevents dust and dirt build-up occurring, ensuring peace of mind and increased efficiency. VERTICAL Vertical Installation Using optional parts, the Lossnay RVX3 range can be installed vertically*4, expanding the number of installation possibilities. *4 LGH-RVX3160/200 are unable to be installed vertically WEEK 1 Weekly Timer Optimise airflow for each application with the new PZ-62DR-E*5 remote controller. The operation pattern for each day of the week, ON / OFF functionality, and air volume can be set using the weekly timer function (up to eight separate Start/ Stop patterns per day over a 7 day period). Compared to previous models, much finer control contributes to enhanced energy saving operation. With a wider range of air flow control, the Lossnay LGH-RVX3-e range enables optimised ventilation not just at different times of the day, but for different days of the week, enabling further energy savings. *5 PZ-62DR-E purchased separately. 2 Optimised Control with Optional CO2 Sensor Through the addition of optional Mitsubishi Electric CO2 sensors, CO2 levels can be detected, and airflow intuitively adjusted to ensure optimum air quality, no matter how many people are within the space. The system will continuously adjust the volume of fresh air changes until optimum CO2 levels are reached, with the system then reverting back to the original fan speed. Make Heat Recovery Ventilation Visible – with Optional Lossnay Wi-Fi Control Elevating air quality and maximising energy efficiencies within your commercial building has never been easier, because now the power is in your hands. Lossnay Wi-Fi Control allows you to see by how many degrees Lossnay is pre-warming or cooling your space in real time, helping you save on your power bill because less additional heating is required to get a room up to temperature. And in summer, monitor by how many degrees Lossnay reduces the average temperature in your space, using Automatic Free Cooling*6 Mode. The app will also proactively remind you when it is time to clean your filters to maximise both cost efficient operation and health benefits. Lossnay Wi-Fi Control truly is the smart evolution in fresh air ventilation. And with the option of an additional CO2 sensor, when connected with the optional Wi-Fi Control Interface, CO2 levels can be viewed in real-time making it ideal for schools, medical facilities and offices. * 6 In comparison to using a dedicated cooling device. The unit will continue to use a small amount of power to bring colder fresh air from outside. ©Mitsubishi Electric Corporation 1 ENERGY RECOVERY VENTILATORS LGH-RVX3 series
