1. Crossflow heat exchanger: Made of Aluminum, cross flow passages, sensible heat exchanger.
2. Fresh air filters: Triple filtration to ensure air cleanness, G4+F7+H10.Aluminum frame, solid, stable, ametabolic and anti corrosive.
3. Return air filter: Nonwoven material, G4 class, filtering return air.-Aluminum frame, solid, stable, ametabolic and anti corrosive.
4. Bypass system: By adjusting the opening angle, different fresh air volume can go through theheat exchanger and by-pass synchronously. When it’s opened completely, the air goes without passing the heat exchanger.
5. Compressors: Made by Panasonic, rated cooling capacity is 2410W.-R410A refrigeration, environment friendly.
6. Evaporator: Plate fin heat exchanger, with coated hydrophilic fins.
7. Connection box: Circuit board, core of intelligent control system-Power switch, power supply to the compressor, fans and by-passWiring terminal, easy access for field connection.
8. Electrical heater: 1200W power controlled by the intelligent set program signal.
9. Drain tray: Made of coated galvanized steel, collecting the drain water from heat exchanger, evaporator and condenser.10. Drain pump-Integrated with ball cock to test the water level, the water is drain out automatically if the water is full.

Q1:what’s your ERV machine’s advantage?
A1: overall filtering, adopt multi-filtering screen, the efficiency of filtering rise up to 99%.
Q2:can you accept customized needs?
A2: we can do OEM sevice for customers. The specifc needs can be negotiated
Q3:Are your machines energy-saving?
A2: yes, our whole series of ERV adopts EC fan motor, less electricity cost, and safer.
Q4: Do your machines have controller board to monitor its operation?
A4: yes, our ERV machines are equipped with our own developing system integrated into its controller board, it’s convenient for customers to ask to find problem accurately and timely.
Q5: how do you guarantee your service timely?
A5: both of our engineers and salesmen work at factory office, it can reflect customers’ feedback as soon as possible after shortening the distance between sale department and technical department.
Q6: Can your own system be interfaced with other control center by establish communication protocols?
A6: yes, we have many such experiences in this part.
