Service and Maintenance

Question 1

What are the advantages of waste gas treatment from DAS Environmental Experts?

Accepted Answer

DAS EE combines technical expertise with decades of experience in the industry. The systems are durable, energy-efficient and customisable – developed and manufactured in Dresden, used worldwide.

Question 2

How do I select the right waste gas treatment process for my process?

Accepted Answer

The selection depends on several factors, including:
Type and concentration of pollutants

Temperature, humidity and volume flow of the waste gas

Process conditions and available operating resources

Space requirements and maintenance requirements

DAS Environmental Experts analyses each application individually and develops the appropriate solution based on this analysis – from process analysis to tailor-made systems.

Question 3

How do we deal with customer inquiries, complaints and service cases?

Accepted Answer

At DAS Environmental Experts, we put customer satisfaction at the heart of our corporate philosophy. Our Customer Care and Technical Support Teams worldwide ensure that inquiries, complaints, and service cases are handled professionally, quickly, and transparently. A ticket-based system with defined process steps, including root cause analysis and 8D methodology, ensures timely responses and systematic handling of all feedback. Responsibilities are clearly assigned, and escalation processes are in place to notify customers proactively if service levels are at risk. 
Customer feedback is thoroughly documented in a traceable complaint ledger, and all cases are regularly analyzed to identify patterns and drive continuous improvement. If an issue relates to internal operations, relevant employees are involved in the review to ensure process awareness and accountability. 
We offer a full range of post-delivery services, including spare parts supply, warranty and out-of-warranty support, and clearly defined service specifications. Our inventory management ensures the availability of required consumables and parts at all times. 
To ensure a high-quality customer experience, we conduct regular customer satisfaction surveys and integrate findings into our risk and opportunity assessments. Customer requirements are captured via our CRM system, contractually reviewed with the support of our legal department, and communicated across all relevant teams to ensure consistent delivery. 
Our internal training program and our Innovation and Support Centers ensure a skilled workforce at any time. With well-trained and experienced personnel, structured service processes, and a strong commitment to responsiveness, we ensure long-term customer satisfaction and reliable support throughout the entire product lifecycle.

Question 4

How do we ensure safety in operation?

Accepted Answer

At DAS Environmental Experts, safety is a fundamental aspect of our operational philosophy. All our products are third-party certified to comply with SEMI S2/S8 and CE standards, ensuring full alignment with the EU Machinery Directive and applicable regulations for electrical and mechanical safety. To secure smooth distribution processes we comply with the Airfreight Security Program (Known Consignor) of the German Federal Aviation Office. 
Based on systematic occupational health and safety (OHS) risk assessments, we implement targeted safety measures across all work areas. These include grounding of equipment, clearly visible safety labels, and specific warnings for hazardous substances where applicable. 
Hazardous substances are not part of our delivered systems and are not transported by us. However, when we handle chemicals in the course of our internal operations, they are stored in certified hazardous substance cabinets and a dedicated chemical storage area—both designed in accordance with legal and safety requirements. This includes explosion-proof lighting, fire safety equipment, spill containment, and environmental monitoring. Regular monthly safety inspections are conducted, and containers are cleaned, inspected, and decommissioned as required by law. 
Our waste management system includes a separate, clearly marked waste storage area with categorization based on legal requirements. Hazardous waste is not treated on-site, but collected and disposed of exclusively by certified external partners. 
Our fire protection systems comply with local regulations and have been validated by the relevant authorities. By systematically integrating OHS principles into daily operations, DAS EE ensures a safe working environment—for our employees, partners, and customers alike.

Question 5

How do we handle Procurement, storage and quality of materials?

Accepted Answer

To ensure consistently high product quality, DAS Environmental Experts relies on a robust supplier and material management. All main materials and parts are procured exclusively from qualified suppliers, listed and managed via our ERP system. Supplier performance and component quality are continuously monitored, and any nonconformities are addressed through a formal claims process, with full traceability in our systems. Materials and parts that do not meet quality standards are quarantined in a dedicated blocked storage area until resolution. 
Our warehouses are organized into clearly defined zones with appropriate labelling and efficient access routes. Environmental conditions such as temperature and cleanliness are strictly maintained—standard storage temperature is 20°C, and sensitive materials and parts are stored in individual bins or on pallets. We use suitable transport and handling equipment and conduct regular checks on reusable packaging materials to ensure safety and integrity. 
Hazardous substances and waste are stored in accordance with all legal and safety requirements. We operate a central chemical storage area and several compliant hazardous substance cabinets, and our waste handling follows a categorization system aligned with national regulations and our certified disposal partner. 
By combining certified storage practices with proactive supplier management, we ensure material and parts quality and compliance from procurement through to production.

Question 6

How do we secure Product and Process Quality at DAS Environmental Experts?

Accepted Answer

At DAS Environmental Experts (DAS EE), quality is an integral part of everything we do. As an ISO 9001 certified company, we follow a structured and transparent quality management system embedded in our Integrated Management System (IMS). Product development is guided by clearly defined gates, mandatory design reviews, and cross-functional stakeholder involvement to ensure compliance with customer requirements and regulatory standards. 
We use a Product Lifecycle Management (PLM) system to document, review, and track all technical changes, supported by a workflow-based four-eye principle and audit-proof revision management. All DAS EE products are third-party certified in accordance with SEMI S2/S8 and CE standards. 
Changes that affect product performance undergo defined testing procedures, including internal lab validation, installation checks, and—in some cases—field tests. Materials and critical components are clearly labeled and traceable, and all testing equipment is regularly calibrated and documented. 
Our approach ensures reliable performance, traceability, and continuous improvement — across the entire product lifecycle and at each DAS site worldwide.
