Feedback from teams who rely on our cleanroom HVAC and pressure control systems every day.

“The DPT-3000 transmitters gave us stable readings across four airlocks. Calibration held after six months without drift. We ordered two more for the new isolator line.”

Drishti Pradeep Sabharwal Lab Operations Lead, Virar Pharma

“We replaced an older HVAC controller with the CRCS-500. The cascade pressure logic cut our alarm events by 70% in the first quarter. Remote access is a real time-saver.”

Aditi Ray Facility Engineer, Mumbai Bio Labs

“HEPA module installation was straightforward with the T-bar grid kit. The scan report came back 99.997% at MPPS. No leaks, no rework.”

Komal Kumar QA Manager, Palghar Research Centre

“The team at PharmWare helped us design the airlock sequence for a Class 10,000 cleanroom. Differential pressure targets were met on the first commissioning run.”

Aarti Varkey Project Engineer, Thane Diagnostics

Cleanroom HVAC & Filtration FAQ

Answers to common questions about pressurized enclosures, HEPA terminal modules, and differential pressure control for industrial laboratories.

Still have a question?

Contact our engineering team for a tailored recommendation based on your lab’s classification and airflow requirements.

What HEPA grade do I need for ISO 7?

For ISO 7 cleanrooms, we recommend H14 HEPA filters (≥99.995% efficiency at MPPS). Our terminal modules are factory-scanned and certified per EN 1822.

How do you maintain pressure differentials between zones?

We use cascade pressure control with DPT-3000 transmitters and PID loops in the CRCS-500 system. Each airlock has independent setpoints and alarm thresholds.

Can the HVAC control system integrate with existing BMS?

Yes, the CRCS-500 supports BACnet and Modbus RTU. It can log 12 months of trend data and provide remote monitoring via a web interface.

What is the typical lead time for a terminal HEPA module?

Standard H14 modules ship within 2–3 weeks. Custom sizes or gel-seal frames may add 1–2 weeks. We provide a factory test certificate with each unit.

Do you offer on-site commissioning and validation?

Yes, our team performs airflow balancing, pressure cascade verification, and particle count testing. We also supply NIST-traceable calibration certificates.
