Holtop Factory

What's Eco-Smart?

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.

Silencing operation

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.

Cross counter flow plate heat exchanger

It is made of ER paper which has high moisture permeability, good air tightness, excellent tear resistance, and aging resistance. 

Two air streams pass through counterly, and increases the heat exchane area in a large degree.  Thus, the efficiency is much more higher.  

Saving your running cost further, reducing air conditioning load

Costs reduce by 30% per year than conventional AC motor ERVs.
