Holtop High Efficiency Eco design ERV Forced  Fresh Air Energy Recovery Ventilation System


Product Description

In the past, building owners and facilities managers reduced fresh air levels to save on energy costs at the expense of health. This reduction is no longer necessary due to the increased availability and code requirements for Energy Recovery Ventilation (ERV). ERVs reduce fresh air ventilation costs by up to 80% by using recycled energy from building exhaust air. In addition to lowering operating expenses, ERVs help control humidity and often pay for themselves by lowering heating and air conditioning capital equipment costs.



Modern buildings are being built tightly to improve energy efficiency. Eco-smart ERV is ideal

ventilation solution for energy efficient buildings to reduce ecological footprint and improve human health. The energy can be saved by using DC motors and improving energy efficiency with smart control system, to achieve eco friendly climatic experience.





1. Wide range of airflow, suitable for more application
2. Higher heat exchange efficiency up to 80%
3. Perfect silence design
4. Air filtration and purification
5. By-pass function
6. High airproof feature and easy maintenance









1. Choose the proper installation types based on the building structure

2. Determine the fresh airflow required according to the use, size and number of persons

3. Select the right specifications and quantity according to the determined fresh airflow





The area of a computer room is 60 sq. meters (S=60), the net height is 3 meters (H=3), and there are 10 per-sons (N=10) in it.

If it is calculated according to “Personal fresh air consumption”, and assume that: Q=70, the result is

Q1 =N*Q=10*70=700(m3/h)

If it is calculated according to “Air changes per hour”, and assume that: P=5, the result is

Q2 =P*S*H=5*60*3=900(m3)

Since Q2 > Q1 , Q2 is better for selecting the unit.


As to special industry such as hospitals (surgery and the special nursing rooms), labs, workshops, airflow re-quired should be determined in conformity with regulations concerned.
