Trusted by lab managers and facility engineers

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

What our clients say about our cleanroom HVAC installations

Real feedback from lab and pharma facility managers

Measurable pressure stability across all airlocks

After commissioning the CRCS-500 and DPT-3000 transmitters, our ISO 7 suite maintained ±0.5 Pa differentials for six consecutive months. No drift, no false alarms.

The H14 terminal modules arrived with individual scan certificates. Installation took two days, and the final airflow test passed on the first attempt.

We replaced three older filter banks with the HEPA Terminal Filtration Module H14. Pressure drop dropped by 40 Pa, and the room classification improved from ISO 8 to ISO 7.

The DPT-3000 transmitters communicate directly with our BMS via Modbus. Setup was straightforward, and the ceramic diaphragm has held calibration for over a year.

We needed cascade pressure control for three adjacent cleanrooms. The CRCS-500 handled the logic without extra relays. The touchscreen interface made commissioning simple.

Why spec our cleanroom HVAC over packaged alternatives

We design and install pressurized enclosure networks for industrial labs — not generic comfort HVAC. Every component is selected for differential pressure integrity, not just air change rates.

Our systems are built around terminal HEPA filtration and real-time pressure cascade control. This is the difference between a room that feels clean and one that meets ISO 5–8 classification under dynamic load.
HEPA terminal modules, not ceiling boxes

Each H14 module is individually scanned and certified per EN 1822. The housing includes a gel seal frame and factory-tested gasket — no field-assembled leaks. Airflow capacity from 500 to 2000 m³/h with pressure drop below 250 Pa at nominal flow.

DPT-3000 transmitters with 0.5% accuracy

Ceramic diaphragm sensor with thermal compensation. Measurement range from 0–100 Pa up to 0–1000 Pa. Output via 4–20 mA and Modbus RTU. IP65 enclosure for wash-down areas. NIST-traceable calibration included.

CRCS-500 cascade control for multi-zone labs

Supports up to 32 independent zones with individual temperature, humidity, and pressure setpoints. PID controllers maintain stable differentials between adjacent rooms. BACnet and Modbus integration for BMS. 12-month data logging onboard.

Design and commissioning, not just equipment

We handle ductwork layout, pressure cascade calculations, and on-site validation. Each installation includes a differential pressure test report and filter scan certificate. No hand-off to a third party.
