During the design of data centers, professionals often face the question of raised floor systems versus the use of an overhead cable tray while designing cabling distribution and air handling systems. Twenty years ago, this wasn't even a discussion, as virtually all data centers used raised floor systems, although it has now become a heated debate. While a case can be made for both options, there are certainly many reasons raised floors have remained the industry standard in data centers across the United States.
Perforated raised floors are often used in clean rooms, computer rooms, data centers, large high-end offices, and spaces that require good ventilation. The perforated raised floor is designed to provide excellent cooling to manage the heat load in mission-critical facilities. However, if you want to optimize the ventilation of the perforated raised floor and create the most efficient air conditioning system (UFAD - Under Floor Air Distribution) for the space, it is necessary to properly and correctly lay the perforated raised floor, which also includes selecting the right raised floor perforated tiles according to different environmental needs.
With science and technology advances, the clean room, also called dust free workshop, has become an indispensable working area for electronics factory, medical, food, and other industries. The selection of clean room floors is based on product construction technique, installation and more factors. Now, we bring you four common clean room floor panels with the difference, installation, construction, applications and choosing tips.
Cleanroom flooring systems must take account of the whole production process and materials must be chosen that will not give rise to airborne molecular or particle contamination. At the same time they must withstand harsh cleaning regimes and strong cleaning agents and disinfectants
The bulk of the contamination in a Cleanroom resides on the floor. It is important that consideration be given to the best flooring solution for your application.
Cleanroom floors demand the same kind of special attention required for other details of cleanroom design and construction. Among the criteria for cleanroom floors are:
Concrete is an excellent construction material. Pourable and formable, concrete develops into a hard structural material capable of supporting heavy loads and is durable enough to last for many years. But concrete is porous and subject to wear and to attack from corrosive chemicals. Also, it tends to abrade and give off large amounts of dust, while spilled materials tend to seep into and through it. Even with additives to increase hardness and seal the surface, concrete cannot be exposed in cleanrooms. Still, it forms the base for almost all flooring materials that do provide the required characteristics. These materials must be compatible with the concrete substance and must adhere well for long-term durability.
To maintain the highest level of clean air, Class 1 and sub-Class 1 cleanrooms generally use vertical laminar air flow systems with perforated, raised access floors. Space between the raised floor and concrete-slab on grade is used as a return air duct and also as a service area for wiring, cable and piping. Perforated panels provide a way to achieve vertical laminar flow conditions while controlling ESD, air flow, particulate contamination and vibration. Floor panels vary according to the application and may include aluminum, fabricated steel, aluminum casting, woodcore, gypsum and cement.
Clean rooms are highly sophisticated buildings that fulfill crucial functions for highly sensitive processes. Clean room design and construction is now a special segment of the building industry and accounts for the specification and installation of an ever increasing amount of interior surface finish material. A clean room is a specialized enclosure that establishes an environmentally controlled space where airborne particles, microbes, temperature, humidity, airflow, and other elements are carefully regulated. Clean rooms are no longer used just in the aerospace industry. Today clean rooms are built wherever contamination control is important: pharmaceutical and medical technology labs and production areas; semiconductor, computer, and communication system assembly and testing facilities; optical, biotechnology, food and drink processing plants.
MANY FACILITY PLANNERS, concerned about contamination or potential scheduling delays, once dismissed the thought of installing electrostatic discharge (ESD) safe tile in operational clean spaces. Rather than risk tearing their buildings apart and losing valuable production time, many companies chose alternative methods to ESD flooring to be ANSI/ESD S20.20-1999 compliant. ESD industry control practices may include the combination of wrist straps, grounding cords, floor mats and “Faraday Cage” material handling protocols. Until recently, installing a new ESD floor most often included the difficult taskof removing the old floor first.
