Lossnay LGH-RVX3-E FRESH AIR ENERGY RECOVERY SYSTEM ENERGY RECOVERY SYSTEM The Lossnay LGH-RVX3-E Fresh Air Energy Recovery Ventilation range is designed to supply clean, fresh air into commercial and residential buildings, while 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 outgoing stale air, maximising energy efficiency and reducing running costs. LGH-15RVX3-E 10-42 L/s of air LGH-160RVX3-E 111-444 L/s of air LGH-25RVX3-E 17-69 L/s of air LGH-35RVX3-E 24-97 L/s of air LGH-50RVX3-E 35-139 L/s of air LGH-65RVX3-E 45-181 L/s of air LGH-200RVX3-E 139-556 L/s of air LGH-80RVX3-E 56-222 L/s of air LGH-100RVX3-E 69-278 L/s of air 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 both residential and 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. Optimise Indoor Air Quality Each unit features a treated paper core that transfers both sensible and latent heat, managing humidity and CO2 levels while maximising overall efficiency. Improved Airflow Range Featuring upgraded variable air control for more precise and efficient ventilation. Both supply and exhaust default fan speeds can be adjusted in 5% increments (from 25% to 100%) to accurately match the required airflow for each application. Low Noise Design Operating as quietly as 17dBA*2, the LGH-RVX3-E range meets stringent sound level requirements, ideal for offices, schools, and other occupied spaces where quietness matters most. Improved External Static Pressure External static pressure has been improved by up to 35Pa / 41%*3 compared to previous models, providing greater flexibility in ductwork design and installation options. Vertical Installation Using optional parts, the Lossnay RVX3 range can be installed vertically*4, expanding the number of installation possibilities. 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 all year-round. Not only can dust and dirt build-up typically create unpleasant odours, but it also significantly impairs heat exchanger efficiency. Dual Barrier Coating ensures peace of mind and optimal performance. Weekly Timer Enables Energy Saving Operation Optimise airflow with the PZ-62DR-E*5 remote controller. The weekly timer lets you set up to eight ON/OFF patterns per day across seven days, with adjustable air volume for each. Offering finer control than previous models, the PZ-62DR-E controller enables precise, energy-efficient ventilation tailored to different times and days. *1 LGH-25RVX3-E on lowest fan speed for winter conditions. *2 LGH-15/25/35/50RVX3-E on lowest fan speed. *3 LGH-25RVX3-E model on highest fan speed. *4 LGH-160/200RVX3-E are unable to be installed vertically. *5 PZ-62DR-E purchased separately.
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. Optional Accessories PZ-70CSD-E2 Duct-in Type PZ-70CSW-E2 Wall Mounted Type CO2 levels are indicated by LED lights Make Heat Recovery Ventilation Visible – with Optional Lossnay Wi-Fi Control Elevating air quality and maximising energy efficiencies has never been easier, because now the power is in your hands. See by how many degrees Lossnay is pre-warming or pre-cooling the incoming fresh air to the building in real time, helping save on operating costs 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 using Automatic Free Cooling*7 Mode. In addition, the App will also proactively remind you when it is time to clean filters to maximise both cost efficient operation and health benefits. Lossnay Wi-Fi Control truly is the smart evolution in fresh air ventilation. 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 Please refer to our “Lossnay Filter Range” brochure for more details. *7 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. Optional High-Efficiency Filters Available*6 For spaces where clean air matters most like hospitals, schools and offices, optional high-efficiency filters provide added protection. By capturing fine airborne particles, they enhance indoor air quality, creating a healthier and more comfortable space for everyone.
