ERU Series Central Fresh Air System (Foam Version)
ERU 250 / 350 / 450 / 650
Enchoy Introduction
A fresh and healthy indoor climate is of highest importance for health and well-being as well as energy saving for a better environment and cost effective ventilation solutions. We at Enchoy strive for develop and manufacture high quality energy efficient solutions for ventilation, energy recovery and air purification for each individual need. Enchoy has both the knowledge and the products to find the right solution for your specific needs. We continuously develop our products for a better, healthier and energy efficient indoor climate for a greener world.
Heat exchanger technology from Finland
Enchoy is one of the leaders in heat exchange research and westrive with new technology and long-term development for an intelligent indoor air quality for both health, energy saving and a greener world.
Indoor Air Quality
A correctly specified mechanical ventilation system can ensure the quality of the indoor air is constantly maintained for the health and well-being of the occupants as well as of the building. Duly maintained filters ensure that incom-ingair is suitably filtered of dust and pollen before if enters the home.
Application
Whole house heat recovery and air purification. Suitable for ceiling / false ceiling and wall installation.
Specification
Outer Casing
Outer casing is manufactured with high grade galvanized steel with a strong designed casing and powder coated for maximum corrosion resistance. Standard color.
Inner Casing
Inner casing is manufactured with EPP (expanded polypropylene) for good thermal insulation, low sound emission, fire, proof, water proof and environmentally friendly.
External Motors
Equipped with German EC DC brushless fan. It has the characteristics of maintenance-free, energy-saving and long service life. And the wind speed of air supply and exhaust can be set separately to make ventilation more comfortable.
Features & Benefits
Easy Installation
270mm height for ceiling model and 729 mm for wall mounted, including fixing brackets (excluding drain connection).
Filters
G4 prefilter and F9 high efficient filter that are easily removable for maintenance or replacement. No tooling required.
Preheater
ERU 250/350/450/650 can be connected to external pro/pre heater and are fully implemented in the control system, (optional).
Drainage
The unit is prepared for drainage in the bottom of the unit for usage in colder climate.
Heat Exchanger
Can realize the exchange of temperature and humidity at the same time, Unique vortex plate design and high density and low thickness characteristics, While improving gas isolation and thermal conductivity, the heat exchange efficiency is greatly improved. Enthalpy efficiency is 78%, which is much higher than the level of 55% of similar products.
ERU 250/350/450/650 have fully automatic frost protection controlled by the system. During anti frost process the heat recovery function is disabled.

Professional Heat Exchange Technology
The exchange core is made of Nano graphene polymer material, good temperature resistance at -30℃ to -45℃, effective moisture permeability and no gas leakage, mould-proof and bacteria-proof membrane material. Service life can usually reach more than 10 years.
Can realize the exchange of temperature and humidity at the same time; the unique vortex plate design and the characteristics of high density and low thickness not only improve the gas isolation and thermal conductivity, but also greatly improve the heat exchange efficiency. Enthalpy efficiency is 78%, which is much higher than the level of 55% of similar products in the industry.
