Commercial ERV DX heat recovery unit
with humidifier, 500 m³/h

Commercial ERV DX heat recovery unit LG with humidifier, 500 m³/h

LZ-H050GXH4

  • Cools and dehumidifies the air in summer, and heats and humidifies it in winter, ensuring comfortable indoor conditions all year round
  • The heat recovery system allows for the reuse of thermal energy, reducing heating and air conditioning costs
  • The built-in DX coil and humidification system help maintain optimal temperature and humidity levels for a healthy indoor microclimate
  • The unit integrates easily with building systems and supports convenient control via a wired remote controller
  • ERV DX provides a constant flow of purified fresh air while removing dust, excess moisture, exhaust air, and unpleasant odors
