Eco-friendly Care Mat

https://korean-machinery.com///inquiry[INQ. NO. 1807M12] Due to global climate change and rapid industrial development, our surroundings are exposed to harmful environmental substances. Particularly in South Korea, we need to pay special attention as our health can be damaged by harmful substances, such as yellow dust, fine dust, smog from China, super viruses, murder mites, fine dust of heavy metal, carcinogens including radon that can enter our bodies through the mouth or be brought into buildings from outside by contaminated shoes or clothes.
In this context, U-CARETECH Co. is capturing the limelight in the industry by recently having introduced a breakthrough, the new-concept and eco-friendly ‘U-Care Mat’ in order to block harmful substances at the source and improve the harmful environment.
U-Care Mat is an innovative product that can prevent various harmful substances from entering through the entrance door. Unlike conventional mats, when human access is detected through a photo sensor, the motor installed in the mat is operated and a hole is opened in the part on which the user steps and sucks in the air around the bottom part of shoes, etc. Then, this product collects fine dusts and harmful substances through the filter in the control box and sterilizes them with ultraviolet rays.
U-Care Mat, having obtained KC Certification for the first time in the industry, is strong and durable (the triple structure of upper, middle and bottom plate), and the mat height for it is low and the edge slope is gentle. This product is manufactured with user safety as a top priority.
In particular, in order to reduce noise drastically and to maximize the suction power of the mat bottom, we maximized the suction efficiency by minimizing the contact area of the mat’s upper plate (completed the design registration in 2014). In order to minimize the residues of the top plate and give a neat finishing touch, we injection-molded the end tip of the hose, thus making the hose connected easily and conveniently.
Especially, for protection against an emergency such as a fire, U-CARETECH applied the luminescence line to the ball of the top plate for emergency induction in dark conditions. (Currently the only such product in Korea) Because of the ball characteristics of the mat, static may occur. By using the ball containing antistatic agent, U-Care Tech has considered the consumer’s health as a top priority.
This product consists of a control box and mat. The mat sizes come in five basic types and two directional types range from 600 to 1,000mm and additional orders are available. Especially, the U-Care Mat has the highest efficiency because it exerts strong suction force even to the corner of the maximum size.
U-Care Tech is in the process of launching the mat for family use in addition to commercial mats currently on sale and is leading the technology-intensive global care industry with high technological prospects and growth potential. Jae-un Shin, president of U-Care Tech remarked, “The environmental problem of air pollution will be more serious in the future. We will introduce only the best products leading to solutions of environmental problems through continuous research and development.”

Cleaning Equipment of Refrigerant Pipes

https://korean-machinery.com///inquiry[INQ. NO. 1807M11] It has been announced that a cleaning technology capable of using the existing refrigerant pipes without replacement has been developed.
Bumsuk Engineering has developed a cleaning equipment of refrigerant pipes for the system air conditioner which can use the recovered refrigerant as a cleaning agent.
R22 was the refrigerant of system air-conditioners (multi-conditioners, heat pumps) installed before 2010 in residential complexes, large office buildings, public institutions (schools, libraries, etc.). In cases where an outdoor unit using R22 refrigerant is replaced with a new one using R410a refrigerant, as the existing refrigerant pipe is embedded in a wall or a ceiling, it is often reused as it is without cleaning.
When you use R410a refrigerant for the outdoor unit of newly replaced system air-conditioners, be sure to clean the inside of the already installed refrigerant pipes before reusing it as refrigeration oil or other contaminants are attached to the inside of the pipes.
In the conventional cleaning method, pipes are cleaned by connecting the recovery system and regenerator separately even in case of using either chemical cleaning agent (solvent cleaner) or existing refrigerant. However, mineral oil or residues of acid content existing in the oil cannot be eliminated even by vacuum cleaning over three times; and mineral oil, moisture and acid content are not eliminated even after vacuuming for one week, thereby causing problems such as damage of the compressor.
A spokesperson for Bumsuk Engineering explained, “As all new system air conditioners (outdoor units) use HFC series R410A or R407C (partially imported goods), synthetic oil is used for refrigeration and, as a result, contaminants are generated while the mineral oil passes through the existing pipes. Such contaminants can clog the refrigerant circuit or damage the compressor.”

 

Eliminating impurities by more than 99%

The cleaning equipment of refrigerant pipes developed by Bumsuk Engineering is a single piece of equipment combined with the functions of recovery and regeneration capable of recovering and regenerating the existing refrigerant and uses the recovered refrigerant as a cleaning agent.
A spokesperson for Bumsuk Engineering added, “We obtained a patent for ‘Cleaning equipment for refrigerant pipes in air-conditioners and its cleaning method’ by automatically controlling pressure, temperature and electronic valve with technology of inside of pipe cleaning by using the refrigerant (R22) recovered from the removed system air-conditioner. The patented refrigerant pipe cleaning equipment is a technology-cum-equipment that removes more than 95% of impurities such as oil attached to pipes by cleaning 40 meters of pipes connected to indoor unit for about 20 minutes.”
It is possible to extend the service life of the outdoor unit by eliminating the cause of its failure through cleaning when the equipment is replaced with a new one. By reusing the pipes, you can expect saving of installation costs and work time as well as reduction of waste. Especially, as the cost for removing the refrigerant pipes installed in both the outer and inner walls and the roof is not required and the pipes are reused, you can reduce costs drastically.

DGA-X

DGA-X is a product that analyzes multi-pollutant (NOx, SOx) gasses from industrial boiler chimneys and reduction facilities or chemical process of air-pollution emissions. The method of the product is by inserting the probe and detector directly into the chimney/duct where the gas flows and measuring the gas concentration inside the chimney/duct. This product has a feature of fast reaction speed and does not require a separate preprocessor, thereby making it easy to install and use.
As for the measuring method, an optical mode is used in a large amount of gas and continuous measurement. SO2 and NOx contained in the emissions have an absorption band in the region of 200 to 300 nm of ultraviolet rays. It uses the Differential Optical Absorption Spectroscopy (DOAS) based on the Beer-Lambert Law which has combined the Beer Law that the absorbance is proportional to the concentration of the absorbed substance as the emissions have the absorption band of ultraviolet rays and the Lambert Law that the absorbance is proportional to the thickness of the absorption layer. It extracts the interference components between the gases by separating the gas component, the dust and the signal on the optical path among the optical signals inputted to the analyzer by replacing the optical path corresponding to the standard gas or the reference path with a mathematical algorithm.

 

DST-X

DST-X is a chimney gas measuring instrument of continuous sampling type, which is a continuous automatic measuring instrument for measuring components of emissions from a chimney. Its principle is analyzing the gas which absorbs energy in the ultraviolet (UV) region by utilizing the UV light source. In general, it measures concentration of the sample gas by injecting the sample taken from the chimney in the extractive (continuous sampling) method with the sample probe into the gas cell of the measuring instrument through the pretreatment system.
It has adopted the method of analyzing the gas type and gas concentration by using ultraviolet rays of 200~400 nm region. DST-X has applied two measurement methods of both nondispersive and dispersive methods simultaneously. By selecting non-dispersive light in the first step and separating the light in detail by dispersion in the final step, it minimized the effect of interference gas, thereby improving the accuracy of measurement.
