AMC & Validation Support
DAH Healthcare Solution Pvt. Ltd. provides comprehensive Annual Maintenance Contract (AMC) services for cleanrooms, HVAC systems, modular operation theatres, ICUs, and critical cleanroom equipment, ensuring continuous system reliability and performance. Our preventive and corrective maintenance programs are designed to maintain key environmental parameters such as temperature, humidity, airflow, and pressure differentials within specified limits.
In addition to maintenance, DAH offers cleanroom and HVAC validation support to help facilities meet ongoing regulatory and audit requirements. Our validation services include airborne particle count testing, HEPA filter integrity testing (PAO/DOP), airflow volume and velocity measurement, pressure differential verification, and temperature–humidity mapping, conducted in accordance with ISO 14644, WHO-GMP, NABL, and applicable standards.
Backed by strong engineering expertise and field experience, DAH’s AMC and validation support services help clients sustain compliance, minimize downtime, and extend the operational life of cleanroom and healthcare facilities, ensuring that systems continue to perform as designed over the long term.
