ERV, HRV & Low Profile Duct System

[INQ. NO. 2012M15] JungSang E&T is specialized in ERV, HRV and low profile duct systems for air movement components of HVAC, heating, ventilation and air-conditioning systems. Its products will appeal to many customers who need a high air-quality HVAC system.

JungSang E&T 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 air supply.
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 is extracted from the kitchen, bathroom and toilets via design valves to the heat exchanger in the ventilation unit.
JungSang E&T’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, JungSang E&T carries various product sizes for low-profile ducts, and is praised for its high quality. They maximize fan performance, and are available in three sizes to suit a large quantity of air with low resistance at a low noise level. | Blog Magazine of korean-machinery, brands and Goods

Korea’s HVAC Products

Korea’s HVAC companies facing big challenge
from Chinese market

Korea’s HVAC (Heating, Ventilation, and Air Conditioning) industry circle sets a further aggressive aim of advancing into new potential global markets including Southeast Asia through securing high-efficiency and ecofriendly technologies, based on continuous growth in both production and export. Now, Korea is ranked the world’s No. 4 in the industry.

Korea’s-HVAC Korea’s HVAC industry circle at an early stage grasped the potential importance of the HVAC industry as one of the indispensable industries in improving both the living environment and industry production process in a global scope.

Korea has early designated the industry as one of the major growth engines leading the national economy in the global markets while encouraging the companies associated to massively invest in this industry and thus to beef up the presence of those companies in an increasingly competitive global market.

Korean companies’ timely advance into promising markets is expected to spread technological recognition in the nation into the global market, thus contributing to the increase of their awareness in global markets.

One of the current hottest issues facing Korea’s HVAC industry is the massive influx of Chinese HVAC products into Korea. The influx of Chinese HVAC products would be accelerated when the recently signed Korea-China FTA officially comes into effect. Given the current situation when the influx of the nation’s HVAC products is visualized, the ratified FTA will help acceleration of the influx of Chinese products into Korean market.

Meanwhile, the recovery of the global economy and global high attention on the green industry will positively play for Korea’s HVAC companies, which have global competitiveness, especially against Chinese competitors in terms of technology power.

Heat Insulating Material – ILSIN INDUSTRIAL

Heat moves from one material to another. This transfer takes place due to temperature differences between the two. For buildings where uniform temperatures must be maintained throughout the indoor space, heat transfer is not at all beneficial ─ especially in winter. Thus, people use thermal insulators to reduce the heat transfer in order to save money (energy-efficient) and maintain a uniform temperature. However, not all thermal insulators produce the same results. With Ilsin Industry’s Low-E thermal insulator, you can see the difference.

Started in 2001, Ilsin Industry has been supplying heat insulating materials. As a specialist, the firm has earned various certificates regarding quality, environment-friendliness, management, and technology. Its own technologies have resulted in manufacturing reflective thermal insulators and many different types of Low-E thermal insulators. Built upon Ilsin’s motivation, “Achieving the common goal with diverse opinion,” Pogeuni maker’s all employees are keen to develop and provide the best quality and eco-friendly Low-E thermal insulators to customers all over the world.

Pogeuni is Ilsin Industry’s highly functional thermal insulator. This Low-E thermal insulator uses the radiant-heat-insulating principle of aluminum and the heat conductivity and convection insulating principle of volume thermal insulators. Pogeuni can effectively block heat that is being transmitted through conduction, convection, and radiation. It also can keep the heat from slipping out of conduction or convection.

Among many advantages that Pogeuni can offer, here are a few major features: The Low-E thermal insulator is about low radiation due to the low radiation rage of the aluminum film with low radiation coating ;durability resulting from its anti-oxidization process; harmlessness as Pogeuni uses the heat-bonding method without any chemical agent; and eco-friendliness by producing a low level of carbon and CO2.

High-Frequency Induction Heating – KOREA NETUREN

Induction heating is the process in which usually a metal become electrically heated by using electromagnetic induction. A typical induction heater has an electromagnet and a high-frequency alternating current (AC). The technique is useful for both industrial and home use. The most common applications we can find easily are electronic cookers like an oven and an electric range. And, as a specialist, KOREA NETUREN Co., Ltd. is the company to turn to when it comes to the induction heating business.

With its establishment in 1987, the power supply maker has been gradually building its references based on competitive technology and quality, also in close cooperation with NETUREN Japan. As a result, KOREA NETUREN can provide the latest induction heating equipment, transistor type power suppliers, and more, by effectively capitalizing on the principle of high-frequency induction heating.

Applicable to various uses, KOREA NETUREN’s MK16A transistor inverter is the recent offspring of its technology and is equipped with large-current and high-voltage IGBT devices. The system is highly effective performance-wise and space-wise. With its frequency range of 1kHz to 50 kHz at an output ranging from 50kW to 600kW, MK16A operates with a high-speed and low-loss device that can save nearly 5% for input power and 44% cooling water. Transistors, printed circuit boards, and the other components are easily accessible for easy maintenance. Also protective circuits guarantee safety during its inverter operation against coil-interruption, overloaded operations, and the other possible risks.

MK22A model offers the same features with an extended frequency range of 100kHz to 350kHz and its output range 100kW to 600kW. KOREA NETUREN offers induction heating equipment for drive shafts, wheel bearings, rack steering bars, axle shafts, etc. For more information, you can visit
