Residential Ventilation Designed for Cold-Weather Comfort
Fresh air is essential for a comfortable indoor environment. However, during cold weather, opening windows can introduce cold outdoor air and increase the demand on heating systems.The MENRED W5 is a residential energy recovery ventilator (ERV) designed to supply filtered outdoor air while recovering heat and moisture energy from outgoing indoor air.With 350 m³/h rated airflow, up to 500 m³/h maximum airflow and a built-in preheater, the W5 provides an integrated ventilation solution for villas, large residences and cold-climate residential projects.Key Features and Benefits
1. 350 m³/h Rated Airflow for Residential VentilationThe W5 delivers 350 m³/h rated airflow, with a maximum airflow capacity of 500 m³/h.It supports centralized ventilation for residential projects requiring higher fresh air volumes. Final system capacity should be selected according to ventilation demand and ductwork design.2. Built-In Preheater for Cold-Climate ApplicationsCold outdoor air can create challenges for ventilation equipment during winter.The W5 incorporates a built-in preheater and frost protection functions to support energy recovery ventilation in low outdoor temperatures.3. Energy Recovery for Heat and Moisture TransferUnlike ventilation systems that only exhaust indoor air, the W5 incorporates an energy recovery heat exchanger.It transfers thermal energy and part of the moisture energy between outgoing indoor air and incoming outdoor air, helping reduce ventilation-related heating and cooling loads.The published heating efficiency is 90.3%, while the cooling efficiency is 72%.4. EC Fan with G4 + HEPA FiltrationThe W5 features an EC fan for fresh air supply and exhaust ventilation.Its G4 + HEPA filtration system helps capture dust, pollen and fine airborne particles from incoming outdoor air.The unit also incorporates a bypass damper and condensate drain pan.How Does the W5 ERV Work?
The MENRED W5 combines fresh air ventilation, stale air extraction and energy recovery in one unit.Fresh Air SupplyOutdoor air enters the ventilation system and passes through the filtration section before being supplied indoors.Energy RecoveryThe energy recovery heat exchanger transfers heat and part of the moisture energy between outgoing indoor air and incoming outdoor air, helping reduce ventilation energy losses.Cold-Weather ProtectionWhen outdoor temperatures are low, the built-in preheater supports the system's frost protection strategy.Indoor Air RenewalStale indoor air is extracted and replaced with filtered outdoor air, supporting ventilation without relying solely on opening windows.Applications
Villas and Large HomesThe W5 is suitable for larger residential projects requiring centralized fresh air ventilation and energy recovery.Cold-Climate Residential BuildingsFor homes in colder regions, the built-in preheater and frost protection functions support ERV system design during winter conditions.Residential HVAC IntegrationThe W5 can be integrated into residential ventilation designs alongside separate heating and cooling equipment.The final system configuration depends on building requirements, ventilation calculations and installation conditions.Technical Specifications
