Double Clean Window | Flush Mount | Cleanroom & Hospital Grade

Sealed, Flush & Customizable: Double Clean Windows

The Double Clean Window delivers excellent sealing performance with the wall and window on the same plane — providing flexible installation and a beautiful, flush appearance. Manufactured to suit different wall thicknesses, especially 50-100 mm color steel panels, the window is available in double-layer, hollow, and moisture-proof types. Standard, non-standard, and custom designs are accepted per user requirements — making it widely applicable to pharmaceutical, food, biological, electronics, and other production workshops.

Excellent Sealing Performance

• High-grade sealing strips around the full perimeter create an airtight bond with the cleanroom panel — preventing drafts, dust, and airborne particles from crossing the boundary and maintaining indoor purification.

Same-Plane Installation — Wall & Window Flush

• The wall and window are on the same plane — no protruding edges, no dust-collecting ledges, no shadow gaps — the continuous surface wipes clean and presents a beautiful, professional appearance.

Flexible & Beautiful Installation

• The flush, same-plane design allows flexible placement anywhere along the partition wall, while the clean seamless look enhances the overall facility aesthetic.

Made for Different Wall Thicknesses — Especially 50-100 mm Panels

• The window is manufactured to match the actual wall thickness, with special suitability for 50-100 mm color steel panels — ensuring a perfect fit with standard cleanroom partition systems.

Three Types — Double-Layer, Hollow & Moisture-Proof

• Available in double-layer (double-glazed), hollow (insulating air gap), and moisture-proof configurations — matched to the insulation, acoustic, and humidity requirements of each environment.

Standard, Non-Standard & Custom Designs Accepted

• Standard sizes stocked, non-standard sizes available, and user-special designs accepted — every project gets a window that fits its exact requirements.

Widely Applicable — Pharma, Food, Bio & Electronics Workshops

• Widely applicable to pharmaceutical, food, biological, electronics, and other production workshops — where sealing, cleanliness, and flush aesthetics are essential.

Applications:

Sinopek is a high-tech provider of comprehensive cleanroom engineering solutions, originating in China and serving a global clientele. For over two decades, we have focused on delivering one-stop, turnkey engineering services that span the entire project lifecycle—from conceptual design to lifelong maintenance. We are not merely builders of physical spaces; we are strategic partners deeply committed to ensuring process reliability, operational efficiency, and regulatory compliance for our clients.

Our Core Strengths: Integrated Delivery and Full-Lifecycle Support

We recognize that a successful cleanroom project is far more than an assembly of equipment and construction materials; it is a systematic engineering endeavor that spans the facility's entire lifecycle. Sinopek creates unparalleled value for clients through four core pillars:

Precise, Forward-Looking Consultative Design
Our design team—comprising process experts, HVAC engineers, and registered architects—adheres strictly to the principle that "process requirements drive design." We are not only well-versed in the highest international and domestic standards (such as ISO, GMP, and FDA) but also possess deep expertise in the specific requirements of sectors like semiconductors, lithium batteries, biopharmaceuticals, and medical devices. From the initial planning stage, we comprehensively address energy efficiency, cost control, and flexibility for future expansion. By proactively mitigating potential risks, we lay the foundation for optimal total-cost-of-ownership for our clients.

Reliable, Efficient Modular Manufacturing and Global Delivery
We take pride in seamlessly blending the modular concepts of "German precision engineering" with the supply chain efficiency of "Smart Manufacturing in China." All core components are precision-prefabricated and pre-assembled on automated lines within Sinopek’s own modern, clean-standard factories, undergoing "zero-defect" factory inspections that exceed ISO 9001 requirements. Supported by a global digital logistics network, we ensure that every shipment reaches project sites worldwide safely, on time, and under controlled conditions. This enables "install-upon-arrival" capabilities, significantly shortening construction timelines.

Professional On-Site Installation Across Borders
Sinopek possesses mature global project delivery capabilities. We have assembled an international project management force that combines a technical core of senior Chinese engineers with local professional teams to ensure successful implementation. Leveraging our proprietary "Cloud-based Project Management Platform" and a deep understanding of local regulations and culture, we efficiently coordinate resources and overcome the challenges of overseas construction. We ensure the precise, "right-first-time" execution of every project and guarantee successful passage of the strictest local third-party verifications.

Smart, Responsive Full-Lifecycle Services
Our service commitment begins after project delivery. Utilizing IoT technology and the "Sinopek Cloud Service" platform, we provide clients with 24/7 remote monitoring, preventive maintenance, and big-data-driven energy efficiency analysis. Whenever and wherever issues arise, our engineers respond immediately with comprehensive solutions—ranging from online diagnostics and rapid spare-parts delivery to on-site support—to ensure the continuous stability and regulatory compliance of the client's production environment, ultimately securing long-term asset value and worry-free operations.
