Yes. Electropolishing is an electrochemical process that simultaneously smoothes micro-roughness reducing the Ra value and passivates the surface by removing free iron and enhancing corrosion resistance. This results in a smooth non-sticky surface that is easier to clean and significantly less prone to retaining biofilm or particulate matter. The process and testing protocols are covered under the ASTM B912 standard, and research consistently confirms a notable reduction in Ra following the electropolishing of 316L stainless steel.

In hygienic design, a threshold of Ra ≤ 0,8 μm is commonly used because this level of smoothness is proven to aid in cleanability and cleaning validation. Even lower values achieved through electropolishing further facilitate sterilization. In practice, the goal is to achieve the smoothest functionally optimal surface required for the specific process.

Yes. Industrial practice shows excellent compatibility of VHP with 300 series stainless steel (304 and 316L) as well as aluminum, provided that correct procedures and sealing materials are selected. For repeated cycles, 316L is typically more robust due to its superior corrosion resistance.

Use non-corrosive, non-acidic, and chloride-free detergents, rinse with plenty of clean water, and if necessary, wipe dry with single-use cleanroom wipers. Avoid abrasives and long-term contact with concentrated chlorides such as hypochlorite, as they accelerate pitting corrosion, especially on 304 stainless steel. If you must use them, minimize the concentration, limit exposure time, and perform a thorough rinse with water.

Yes. In cleanrooms antistatic (ESD) castors reduce static buildup, thereby attracting fewer dust particles while simultaneously protecting sensitive electronics from electrostatic discharge. The right choice of wheels ensures smooth, quiet, and low-particle movement of the equipment.

Of course. When facility standards or validation protocols prohibit drilling, we utilize special clamps and self-supporting structures that do not damage the room envelope. This is frequently required in GMP environments and validated zones, and it is fully included in our standard suite of solutions.

Aluminum has significantly higher thermal conductivity (≈205–235 W/mK) than stainless steel (≈15–25 W/mK), which is why aluminum drawers are frequently used in refrigeration and ultra-low temperature (ULT) equipment. They transfer heat faster, are lighter, and put less strain on mechanical systems at low temperatures. However, for highly corrosive zones, 316L stainless steel remains the most robust choice.

ISO 14644-1 specifies air cleanliness classification by particle concentration (ISO 1 to 9). If you want to consistently achieve for example ISO 7 to 8, the furniture must also be designed without particle traps: fully welded joints, rounded edges, smooth surfaces, easy cleaning, and minimal particle generation during movement (castors and seals).

Prior to manufacturing, we prepare 3D models (STEP) and technical drawings (PDF/DWG). Upon delivery, you receive material certificates ensuring batch traceability, processing records such as passivation according to ASTM A967 or electropolishing according to ASTM B912, and IQ/OQ support if required. The goal is to ensure the equipment seamlessly passes internal and external audits.
