Heat Recovery Ventilation System
Heat Recovery Ventilation System
Exchange outdoor fresh air with indoor contaminated air
Getting IAQ to the Next Level
Heat recovery ventilation unit fitted with a heat recovery core and two motors. The airflows move bidirectionally. With the heat recovery, the heat or cold that would be otherwise be lost by natural ventilation is recovered. By recovering the energy, electricity consumption would be reduced.
Supply Fan
To form a continuously circulation of air for the indoor by delivering fresh air to indoor.
Extract Fan
To form a continuously circulation of air for the indoor by delivering contaminated air to outdoor.
Heat Recovery Core
For the exchange of heat and energy from the air by crossing each other in different layers of the core.
Heat Recovery Ventilation Unit
a standard for home and working venues
The design of the products are flexible for installation, high performance, energy saving by equipping the latest innovative technology.
Heat Recovery Core
Counter-flow plate heat exchanger with an optimal distance between layers to ensure a high heat recovery efficiency and a smooth movement of the airflows. Counter-flow heat exchanger provides a long distance flows of air and with a large plate area. Material with Graphene used also has a high heat recovery efficiency, where the counter-flow heat exchanger is washable and durable, anti-mold, anti-viral and anti-bacterial. No cross contamination during the air exchange process, the fresh air from outdoor and the contaminated air from indoor move in separate layers where they don’t contact each other.
Fan Motor
The high performance Variable Speed Drive (VSD) EC motor equipped in the unit has the features of low power consumption, quiet and high static pressure. This not only reduces the long run electricity cost, but also ensures the air delivering to the room is sufficient after ducting. EC motor provides an excellent overall performance including energy saving.
Bypass Damper
All models are equipped with a bypass damper for summer bypass (free-cooling). Without exchanging the heat at the heat exchanger, the fresh air with comfortable temperature level from outdoor can be delivered into the room directly and the hot air from indoor can be exhausted to the outdoor directly. Automation of the bypass function depending on the internal temperature sensors is also available when pairing with Control System Model VK8.

More about the unit
The models are equipped with ducts that is easy for ducting connection. With a rubber circular band on the ducts, this helps putting installation at ease.
External Casing
The models with coated sheet steel housing, CS and W Series, are equipped with 15mm-20mm internal heat and sound insulation, while TP Series designed with EPP housing has a insulation of 30-45mm.
Service Panel
With the service panels of filters at the front of the unit, this reduces the service space needed especially when the unit is installed in an apartment. The slim designs fit better when the unit is installed in the ceiling or in the wall.
Filter
G4 extract filter and G4 supply filter are fitted as standard in each unit. F8 supply filter is optional. H11 supply filter is available upon request (H11 filtering efficiency of PM2.5 is >99.9%).
98%
MAX. HEAT RECOVERY EFFICIENCY
Installer can choose which ports facing which sides for a better installation by simply flipping around the unit to the other side. No modification to the unit is needed.
The unit has a high performance in heat recovery which means a reduction of heat or cold loss for indoor, thanks to the double heat recovery core, it increases the size of the total area that the air crosses through so as to also increases the length of the heat recovery process.
The design is slim and fit for ceiling installation. The advanced internal structure makes this slim height possible. It balances different parameters to the optimal, from heat recovery efficiency to airflow. A complex and admirable structure together with high density spacing heat recovery cores and the outstanding strength of the motor, plus the unique design of the bypass airflow channel, makes the unit to have a high overall performance.

W OPTIMAL Series / W PREMIUM Series
Designed with service panels on the both sides, which installers can choose for left or right orientation by simply turning the unit over to the other side with the same unit.
TP THERMAL Series
EPP has properties of light weight, heat and sound insulation. With a full EPP housing and structure from internal to external, the unit has an internal insulation of 30-45mm, which enhances the heat and sound insulation level. Counter-flow heat recovery cores, high static pressure and ultra silent EC motors, built-in bypass system, class G4 and F8 filters are some of the main configurations of the product.
TP THERMAL Series
The classic four ports on the top for installation fits residential uses and also fits office uses. Ports with circular rubber band for easy ducting connection, easy-open service panel and easy wall mounting are some of the features for installation and maintenance. The unit can be installed in left hand or right hand, it can be just simply turned around to the other side for another orientation. Both sides have the service panel for filters or heat exchangers maintenance.
