Energy-Recovery Ventilation Unit

https://korean-machinery.com///inquiry

 AP Co., Ltd., established in 2008 is a KS-certified company for Energy Recovery Ventilation (ERV) air circulation units and fan coil units (FCUs).
AP is a growing company based on differentiated technology and stable production capacity, with its headquarters and manufacturing facilities located in Paju, Gyeonggi-do, Korea.
AP produces and sells various air conditioning-related products necessary for different living environments through detailed analysis of product demand.
A ventilation unit is a device that transfers heat contained in the exhaust air during ventilation to the air supplied through a heat exchanger and returns it to the room.

Recovering over 70% of temperature
AP’s ventilation unit recovers over 70% of temperature. When cooling, it uses dry and refrigerated exhaust to humidify and cool the outside air; and when heating, it uses the exhaust energy to humidify and heat the outside air, thereby saving energy required for heating and cooling.
AP’s ventilation unit is thus a device that allows ventilation with the door closed in modern housing environments with increased efficiency.

In addition, the ventilation unit is effective in lowering the concentration of harmful new house syndrome substances by exchanging polluted indoor air with fresh air outside; and it lowers the concentration of indoor carbon dioxide, which cannot be achieved with an air purifier, by bringing in fresh air from outside.

Aluminum Formworks

https://korean-machinery.com///inquiry

Established in 1985, SAMMOK S-FORM CO., LTD. is a company that specializes in manufacturing, selling, and leasing aluminum formworks used in various construction sites.
SAMMOK S-FORM provides clients with eco-friendly and technology-intensive solutions for safety, constructability, expandability, and worker-environment improvement in national industrial infrastructure, housing, apartments, and multi-use buildings.

Reducing labor and processing by 30-40% compared to conventional formworks
Aluminum formwork can reduce labor and processing by 30-40% compared to conventional formworks, and post-processing is possible without special processing of cutting concrete after pouring. Aluminum formwork has uniform horizontal and vertical lines, which increases the efficiency of finishing material construction, and is eco-friendly because it does not require plywood replacement like conventional materials. In addition, it is easy to move and store after construction is completed, does not rust, and has expandability that can be applied to other sites.

SAMMOK S-FORM has developed gang formwork for high-rise residential and commercial sites of 30 stories or more, high-tech systems, and automatic formwork lifting systems (S.C.S, G.C.S, PCS), and thus has contributed greatly to the development of national key industries by promoting the import-substitution effect in the domestic market.

SAMMOK S-FORM is expanding its business territory in overseas markets such as India, Malaysia, Vietnam, Singapore, Brazil and Saudi Arabia through the S-FORM brand.
SAMMOK S-FORM has secured a large number of aluminum formwork systems through long-term investment and is the first in Korea to have complete requirements for a series of production processes ― from melting, to extrusion, production and leasing.

SAMMOK S-FORM is securing existing excellent business partners and seeking to discover new excellent business partners, and is using sales strategies to strengthen pre- and post-customer service.
The CEO of the company explained, “We will strengthen our domestic and international competitiveness through continuous quality innovation and the introduction of a pre- and post-customer management system,” adding, “We will not be satisfied with being a leading company in the country to achieve constructive and future-oriented growth in overseas markets ― based on the successful business model we have built through our domestic business.”

Sludge Treatment System

https://korean-machinery.com///inquiry

BLUEWIN CO., LTD. is an EPC manufacturing group for all kinds of sludge treatment processes.
With over 40 years of experience in over 60 countries and know-how of customers’ networks and field experience, BLUEWIN has been able to deliver timely delivery of optimal products at optimal prices to meet the needs of customers locally and overseas.

Sludge generated from public sewage and factory wastewater is also not buried or incinerated. Sludge with calories is produced with up to 90% DS, mixed with sawdust and hay, and compressed to produce pellet fuel, and it can be used as a renewable energy source with high calorific value (2,500-3,500 kcal/kg).
If about 20~25%ds dehydrated from the 1st-stage mechanical dewatering machines such as beltpress, filtrepress, screwpress, centrifuge, vacuumpress, and volute screwpress are reclaimed or incinerated as they are, then it results in high treatment costs and serious secondary environmental pollution.
However, if it is reduced to 80-90%ds and dried, high-quality renewable energy can be produced – and secondary environmental pollution can be reduced by more than 99%.

ELODE+NVD combination system
This system can process 80~90%ds in the shortest time with the lowest OPEX and CAPEX cost. It is simple and compact, allowing large-capacity processing in a small space.
It does not require as much space or maintenance costs as a rotary dryer, film dryer, low temp dryer, and thermal dryer. ELODE+NVD with the best competitiveness is now the latest trend.
The earlier you choose, the faster your ROI will surely be. If sludge of 20% DS per day is processed at $100/ton, 30 tons/day will require expenditure of more than US$1 million per year – but if ELODE+NVD is installed, such costs can be reduced by more than 90% and the initial purchase cost can be recovered within 24 months.
ELODE+NVD is not supplied directly to end users. It must be provided and managed through the sole agent only. Those who wish to become a sole agent only need to purchase EODS-500. If you become a sole agent, you will be invited to Korea for 15 days to complete pre-training.

Vacuum Pump

https://korean-machinery.com///inquiry

dooVAC’s DEN 400 is a water-sealed vacuum pump developed by complementing suction pumps exclusively for dental hospitals. The basic structure of the product is simply composed of a turbo-fan wing and a cylinder.
Water-sealed vacuum pumps are well-suited for processes in which the incoming air contains corrosive gases or large amounts of water by vacuuming in a sealed state with liquid inside a cylinder.

For this application, a filter, a vacuum gauge and a pressure controller are installed in the suction pipe, filters and valves in the water supply pipe for leak prevention. In addition, a double-temperature sensor and an overload protection-switch protect the motor.
To ensure safety in using electricity and water at the same time, the company manufactured the product as a practical one-piece by incorporating an electric converter with the product to turn the product on-and-off with DC 24 volt power. One DEN suction pump can be used for three or four dental chairs at the same time.
The company’s DES402 works for four to ten dental chairs, and can save water and electric power if it is used in large hospitals.
The use of a single large-capacity model can prevent the inhalation pump from shutting down medical services in an entire hospital.
Recently, the DEN 400 product’s symbol sticker has been redesigned. The company adopted a bolder design to enhance the image of the product. It is gaining in popularity in the medical industry and countries where the medical industry is reviving such as Vietnam and Mexico.
dooVAC supplies its cutting-edge vacuum pumps with global quality based on its self-developed technology and accumulated know-how of development. More than 32 years of research and performance improvement resulted in new application fields and innovative products.
Its vacuum pumps are recognized for outstanding performance and technological prowess in the air solution industry, and the company has established a position as a global leader in the vacuum industry.
Lastly, dooVAC started a business in a new factory from August 2020. It attributes the new start to its customers’ support and loyalty.
dooVAC always appreciates your support and looks forward to forming new relationships.
