- Type 1: EPS Panel is covered by two sides, stainless steel, in the middle is EPS foam layer.
- Type 2: PU Panel are insulation panels with PU (polyurethane) core.
- Type 3: Fireproof rockwool Panel, also known as heat-resistant rockwol panel. This material is manufactured in some factories of Vietnam such as: Phuong Nam, Viet Nhat, Dong A ... This product is popularly used to prevent fire in clean room construction, construction of factory roof insulation. , as a temporary fireproof wall for all constructions.
Like fire retardant paint, the rockwool panel is fireproof thanks to the exterior paint and combined with soundproof mineral wool cotton made from dolomite.
II. HAVC system.
HVAC system stands for Heating, Ventilation and Air Conditioning - This is a clean room system that uses air filtration devices to create different levels of cleanliness based on GMP clean room standards, GLP and GSP - WHO. HVAC system controls and controls the concentration of dust particles in the room, creates a difference in pressure between the clean room and the outside environment, regulates the temperature and humidity are always stable within the permissible measuring range. In other words, the HVAC system is a system that creates a clean airflow with the appropriate temperature and humidity values, circulating through the rooms to create different levels of cleanliness.
HVAC systems are installed simultaneously with modular systems to supply and exhaust air to clean room areas. Structure of HVAC systems for clean room projects (including production lines for pharmaceuticals, foodstuffs, cosmetics, factories producing equipment and electronic components, refrigeration, etc.) and rooms biosecurity (including operating rooms of modern standards and biosafety rooms for hospitals). It includes:
- Cluster of inlet air: Prevent insects, rain, dirt.
- Silencer: Reduce noise in operation.
- Wind control valve: Adjust the air flow to control the flow and pressure.
- Control valve: adjust air volume.
- Coil heating: Heat air to the appropriate temperature.
- Refrigeration coil: cools the air to the required temperature, the amount of moisture in the air meets condensation to help dehumidify and reduce the humidity of fresh air entering the clean room.
- Humidifying cluster: If the air humidity is too low compared to the humidity in a clean room, the humidifying cluster will increase the air humidity accordingly.
- Filter: Removes particles with pre-defined dimensions and / or microorganisms. There are two types of filters:
Raw filtration: membrane filter of the AHU, which eliminates particles of large size
Purification: HEPA filters, usually using the H13 type, help remove small particles and / or microorganisms.
- Wind pipe: guide air in the system.
The HVAC system consists of three main cycles:
Supply Air: this cycle helps to supply air into the room, the air here includes cold air and hot air.
Return Air: return new air.
Exhaust Air: air flow is not clean, quality will be discharged outside, usually will be discharged in the toilet.
III. M&E system (heavy electricity, light electricity and fire alarm).
*. Heavy electricity includes:
Main power supply: is the main power supply system, including medium voltage cabinets, medium voltage lines, 24kV / 0.4kV transformers and main switchboards (called MSB, main switch board). There may be more (Automatic Voltage Regulator System, referred to as AVR).
Distribution system of cabinets: Submain power supply
Living lighting system: Lighting
Socket system: Socket outlet
Incident lighting system: Emergency lighting
Grounding system: Earthing system

*. Light electricity includes:
Lan network and Internet: Data network system
Phone system: Telephone system
Security monitoring system: Security & Supervisior system
PA system (public address system) ...
*. Automatic fire alarm system: Helping to promptly detect fire incidents and timely alarms to help minimize damage when a fire occurs.
What is a fire alarm system?
Fire alarm system is a system of equipment that automatically detects and notifies fire locations (according to Vietnam standard TCVN 5738-2001).
Automatic fire alarm system includes: Fire alarm center, fire detectors, (combination of bells, lights, buttons) and other peripheral devices ...
Fire protection system is divided into 2 systems: FA system (Fire Alarm - also known as fire alarm system) and FP system (Fire Protection - also known as fire protection system).
FA system is an electronic system structured like a PLC. Companies all keep their manufacturing technology secret, but keep in mind the following: FA needs safety first, then precision.
The FP system is also divided into many systems such as: FH (fire fighting walls), SP (automatic fire fighting Spinkler), OF (fire fighting overflow ...). Control FP systems are simple and do not use electronic devices to control because people are afraid it will hang. Therefore this system does not have PLC, programming language at all.
V. Water supply and drainage system.
RO water supply and wastewater treatment:
RO technology is currently considered to have a strong ability to filter and handle almost all types of water sources, including alum, saline, polluted water ... Along with the popularity of this technology, many consumers catch water. First concern about RO water and its quality as well as the process of RO water is created.
RO water is a type of water produced by reverse osmosis technology (reverse osmosis). This technology uses ultra-small size filters to filter water at the molecular level. With a filter size of 0.0001 micrometres, most metals, organic matter, bacteria ... cannot penetrate. Filtered water with a reverse osmosis mechanism will flow into a strong stream due to the pressure difference, which pushes residue and impurities to where the pressure is lower and clean water goes on to another filtration level.
The process of removing dirt, impurities
The water produced from RO technology is pure clean, more than 99% of bacteria are removed. Toxic substances, chemicals, heavy metal residues ... are completely non-existent in this country. When used for tap water, RO water has been neutralized, reducing chlorine levels to a safe level. The results of quality tests show that the removal of heavy metals, arsenic, viruses ... of this technology all reached over 90%. Therefore, RO water is completely drinkable directly after being released from the filter, users do not need to boil or through any filtration stage.
In the process of industrial production, depending on the type of production. Wastewater can contain heavy metals, phosphorus, suspended sediments, colors, BOD, COD ... collectively known as industrial wastewater affecting humans as well as the environment. Waste water treatment is a common problem of the whole society in general and of industries in particular. Depending on the characteristics of wastewater, one or more of the following treatment systems may apply:
Mechanical treatment: remove trash, sediment, ... through filters, regulating the flow and concentration of wastewater.
Chemical treatment: flocculation - flocculation - settling.
Biological treatment combined with the denitrification process: removal of organic pollutants from wastewater.
Treatment of sludge: reduce the moisture of mud before being discharged as prescribed.
