Offering the Best System Solution for All Area Ventilation LGH-RVS Series – Sensible Heat Lossnay
Easy Installation Key Features Easy Drain Piping Light Chassis Being light in weight is one of the most important factors for installation. The light chassis of the LGH-RVS series can provide a huge advantage in terms of cost and safety in installation. Low Noise Operation and Energy Ef ciency The LGH-RVS series operates with low noise thanks to a specialized sirocco fan produced by Mitsubishi Electric. The fan balances airflow and static pressure to minimize the noise level. The series also incorporates high-efficiency motor to reduce energy consumption. Low noise and high efficiency are thus achieved with the LGH-RVS series! • Only one drain piping for both SA and EA. • 360-degree drain pipe connection. • Trap piping work is NOT required owing to an internal backflow stopper. Various Optional Parts The LGH-RVS series can connect with various optional parts. A CO2 sensor is one of the best solutions for optimized air volume control. The unit operates while optimizing air volume in accordance with the level of CO2 condensation in the room. Optimized ventilation can reduce the energy consumption of the air conditioner. A high-efficiency filter can be optionally installed in the unit as an easy solution for even better indoor air quality. 1 Drain Piping 190kg A 235kg B 270kg C Competitors 73kg *LGH-100RVS-E LGH-RVS Series CO2 sensor Silencer duct Filter

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 cooling your room 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 your room temperature, using Automatic Free Cooling* Mode. View actual CO2 Levels and watch how the system automatically activates Boost Mode to maintain optimum air quality. 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. *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.

Filters Silencer Ducts Accessories Standard Filter Medium-efficiency Filter High-efficiency Filter A lineup of three types of filters offers optimum indoor air quality solutions! All filters are ISO and EN779:2012 certified, and can be easily installed in the units. Maintenance and exchanges can also be performed easily, simply by opening the maintenance panel. In facilities and applications requiring quiet operations, the silencer duct that reduces noise levels is the ideal solution. It contains glass wool and attenuates sound power by absorbing the noise from the airflow or operation of the unit. 1. Figures on the chart above are based on the comparison with a general steel duct of the same length. 2. The silencer is placed on just before the outlet during the measurement. 3. When the air ow rate differs, the insertion loss is also different from the chart above. 4. Figures on the chart above are at (No-weighted) values.
