Product Overview

Fresh Air Ventilation and Heat Recovery for Higher Humidity Environments

The LossnayPro LGH-100RVS-E is a sensible heat recovery ventilation system designed to supply fresh, filtered outdoor air while extracting stale, moisture-laden air from areas such as bathrooms, kitchens and laundries.

Unlike standard Lossnay Total Heat Recovery systems, the LossnayPro features a non-permeable plastic counterflow heat exchanger, allowing heat energy to be recovered without transferring moisture between the incoming and outgoing air streams.

This makes the LossnayPro particularly suitable for higher-humidity environments, where effective moisture extraction and energy-efficient ventilation are essential.

With a maximum airflow of 278 l/s, the LGH-100RVS-E is suitable for commercial and larger residential applications, including gyms, healthcare facilities, schools and offices.

Key Features

Designed for Moisture-Laden Environments

The non-permeable plastic counterflow Lossnay Core allows stale, humid air to be extracted from bathrooms, kitchens, laundries and other higher-humidity areas without transferring moisture to the incoming fresh air.

Sensible Heat Recovery

Recovers heat energy from outgoing air to pre-condition incoming fresh air, helping maintain indoor comfort while reducing heating and cooling demand.

Energy-Efficient Performance

High-efficiency EC fan motors deliver low Specific Fan Power (SFP), providing effective ventilation with reduced energy consumption.

Flexible Airflow Control

• Four fan speeds with variable airflow control.

• Supply and exhaust fan speeds can be set independently.

• EC fan motors support external 0–10V control.

• Heat exchange bypass function for suitable outdoor conditions.

Quiet Operation

Designed for low-noise performance, operating from just 18 dB(A) at the lowest fan speed.

Easy Installation and Maintenance

• Lightweight chassis for easier handling.

• Multidirectional single condensate drain connection.

• Washable plastic Lossnay Core for straightforward maintenance.

• Accessible components for servicing.

Smart Control and Integration

• Optional Wi-Fi Control Adapter: Enables remote monitoring and control.

• Optional Mitsubishi Electric CO₂ Sensors: Automatically adjust ventilation airflow in response to indoor CO₂ levels.

• BMS Connectivity: Suitable for integration with Building Management Systems.

• Ducted Heat Pump Integration: Can be combined with Mitsubishi Electric ducted air conditioning systems.
