Fresh air heat exchangers Energy Recovery Ventilators
Holtop has manufactured heat and energy recovery ventilation products for over 12 years. We pay high attentions on the energy saving in the modern buildings and indoor air quality, aiming at reducing carbon emission and improving human health. “Eco-Smart” is a new ERV series to bring down energy consumption by using DC motors and improving energy efficiency with smart control system, bringing you eco friendly climatic experience.
Operation noise up to 23dB(A), 2-5dB(A) lower than the ERV with AC motor, making the room more quiet and comfortable, having no influence to your living.
2)Holtop DC motors
- High efficiency, energy saving by 20-60% - Good liability and stability - Easy maintenance - Longer service life - Strong vibration resistance with lower noise and smooth operation - Superior torque performance, big starting torque with less starting current
3) High Efficiency Counterflow Heat Exchanger
Holtop energy recovery ventilator TP series is equipped with high efficiency counter flow plate total heat exchanger. It is made of ER paper which is featured by high moisture permeability, good air tightness, excellent tear resistance, and aging resistance. The clearance between the fibers is very small, so only the moisture molecules of small diameter can go through, the odor molecules of larger diameter are unable to pass through it. By this means, the temperature and humidity can be recovered smoothly, and prevent the pollutants infiltrating to the fresh air.
4)Reducing air conditioning load, save your running costs further
Power input (W)
1)Airflow rate switch (10 speeds)
5)Data memory/power to restart
7)Electric heater defrosting (optional)
8)Comfortable heating (optional)
9)External ON/OFF (optional)
10)CO2 concentration control (optional)
11)BMS integration (optional)
12)Working condition monitor (optional)
8)Working principle of Holtop brushless DC motor heat recovery ventilator
Holtop heat & energy recovery ventilator can expel the stale air indoor out of room, meanwhile supplying the fresh air outside into the room, by using the advanced heat/energy recovering technology, the energy can exchange taking advantage of the difference of the temperature and humidity between indoor and outdoor air. By this means, it can not only smooth away the problem of indoor pollution, but also saving energy.
