ERV, HRV and Low Profile Duct System

JungSang E&T is specialized in ERV, HRV and low-profile duct system for air movement components of HVAC, heating, ventilation and air-conditioning system. Its products will appeal to many customers who need high air-quality of HVAC system.


The company acquired its first CE certification related to Energy Recovery Ventilator (ERV) in Korea since the act on obligatory ERV installation in 2006. As we spend most of our time indoors, it is very important to have good indoor air quality with the ERV system. The stale air flows through a duct and transfers its heat to the plates above and below. Unused fresh air streams in through separate ducts on the other side of the plates. It takes up the heat and is available as warm supply air.
Saving energy by using energy recovery is not only cost-effective and environmentally friendly, but also healthy fresh air is provided constantly without having to keep opening windows. Stale air with humidity, toxins and odors are extracted from the kitchen, bathroom and toilets via design valves to the heat exchanger in the ventilation unit.

The company’s air-to-air heat exchangers, made of corrosion resistant aluminum, are installed within the air-handling units and ventilators to recover heat energy. Its airtight structure prevents cross-contamination of air, making it ideal for providing clean and safe HVAC in buildings such as medical facilities, laboratories, clean rooms and swimming pools. All models are made in Korea. The plate heat exchanger consists of an exchanger housing and recovery cube that is made of aluminum foil fins for heat transfer, corner sections, a bottom and a cover made of galvanized painted or stainless steel.
In addition, the company carries various product sizes for low-profile duct and gets credit for its high quality. They maximize fan performance while available in three sizes to suit a large quantity of air with low resistance at a low noise level.
