Weiss Clean Room Technology: Plan everything from the very beginning Clean Room Technology is a complex domain. For this reason Weiss places importance from the very beginning on a clearly structured, transparent consultation process and on close dialogue with the customer in all phases of the project. What is definitely regarded as clean, is defined in an abundance of standards, guidelines and classification systems. Only those who can find their way through this jungle, can provide solutions which reliably stand up to all tests. Clean Room Classificationan Room Classification Class of Max.

LifeSciences Solutions by Weiss: The fight against Micro-Organisms and Germs In the LifeSciences application sector of clean room technology, considerably higher risks emanate from micro-organisms than from particle contamination. Weiss offers turnkey systems which are specially designed to eliminate this risk and are being successfully used world-wide in the pharmaceutical industry, in foodstuffs, beverage, bio, gene and medical technology as well as in numerous laboratories and research institutes. Quality inspections and assurance for example have top priority for pharmaceutical products. With its comprehensive qualification concept, Weiss Klimatechnik supports the pharmaceutical industry.

Remarks: (a) To comply with room class B, C and D the number of air changes per hour should correspond with the room size, the appliances and persons present in the room. The air system should be equipped with adequate filters, e.g. with HEPA filters for room classes A, B and C. (b) The maximum particle concentration in a non-operative state is in accordance with the classification system of the US Federal Standard 209e and ISO. Thus e.g. room class A and B is equivalent to the air cleanliness classes 100, M 3.5 as well as ISO 5. (c) The requirements and threshold values in these room zones depend on the activities performed there.

Process Control 2 (PC 2) Process Control 2 is a specially developed microprocessor controlled DDC control and regulation system. Process Control 2 is freely programmable and enables the control and regulation of typical parameters e. g. temperature, humidity, pressure, cascade, monitoring of limit values, alarm functions, operation time counters etc. Process Control 2 achieves a minimal energy balance due to an intelligent software program. The required set values and operating limits are entered at the foil keyboard. By means of the freely programmable DDC, the software can be adapted to particular equipment. Data security is assured using EEPROMS. The 4 x 20 digit alphanumerical LCD display shows the measured value, set value, hysteresis, regulation and control parameters, alarm and malfunction reports clearly. The LCD displays all operation modes. The user-friendly foil keyboard allows menu selection and the input of set values and control parameters. Audio and visual malfunction reports with alarm new value and last value reports. For safety, programming at all three user levels is protected by password. With the freely programmable Process Control 2, standard air conditioning functions e.g. heating, cooling, humidification and dehumidification and further functions e.g. fire prevention flaps, volume flow control and post-heating can be programmed.

Air Flow Control: How to remove particles reliably Turbulent Vertical Downward Air Flow Control Supply air enters the room creating turbulence. Sufficient mixing with the room air allows a room temperature constancy of up to ± 0.3 k/m to be maintained. Horizontal Air Flow Control Horizontal air flow is recommended for rooms with low ceilings. A room temperature constancy of ± 0.1 k/m is achieved. Homogeneous Vertical Upward Air Flow Control Supply air enters the room through a raised floor. This air flow system is most suitable for measuring rooms requiring a room temperature constancy of ± 0.1 k/m. This type of air flow is not recommended for clean rooms. Homogeneous Vertical Air Flow Control Supply air enters the room through a suspended ceiling, for clean rooms equipped with integrated particle filters. This type of air flow requires a high room temperature constancy of ± 0.1 k/m. Supply air Return air 22

Cooling of recirculated air: Four options, one concept Direct Cooling Air cooler Cooling unit The evaporator of the refrigerating unit is installed directly in the air flow (direct evaporator). A temporary temperature constancy of ± 0.1 up to 0.5 k and a humidity constancy of ± 5 % r. h. is achieved. Refrigerant Indirect Cooling Chilled water circulates through the cooler. The temporary temperature constancy which can be achieved is approx. ± 0.3 k, the humidity constancy ± 3 % r. h. Air cooler Pump Cold water Cold water Three-way valve Indirect/Direct Cooling Due to the combination of direct cooling of re-circulated air with an intermediate indirect cooling circuit, sophisticated control technology permits a temperature constancy of ± 0.1 k and a humidity constancy of ± 1 % to be achieved. Air cooler Cooling brine Pump Brine tank Cooling unit Air cooler Indirect/Indirect Cooling This is an alternative to indirect/direct cooling of re-circulated air which also permits a temporary temperature constancy of ± 0.02 k and a humidity constancy of ± 1 % r.h. to be maintained.
