Freeze dryer services: retrofits to AMC
End-to-end freeze dryer support: retrofits, control panel upgrades, Windows, PLC and SCADA upgrades, mechanical upgrades, TXV to EEV/ETV conversions, compressor upgrades, SQL Server/SSRS cycle reports and AMC.

Cresco Engineers designs, programs, retrofits and validates control systems for lyophilizers, washing, filling, extrusion and process equipment. We are an AVEVA Registered System Integrator and a B&R Value Provider, and we produce the PLC code, SCADA, panels and IQ/OQ documents ourselves.
Most automation suppliers stop at code. We also build the panel, write the validation documents and come back when the line stops, so you have a single accountable partner across the lifecycle.
End-to-end support for pharmaceutical freeze dryers: control, refrigeration and mechanical upgrades, retrofits and AMC.

Learn more 03Give proven machines a new control system: obsolete PLCs, drives and HMIs replaced with minimum downtime and full documentation.
Learn more 04Design and build of GMP-grade control panels, MCCs and SS enclosures, wired, tested and documented in-house.
Learn more 05URS-to-PQ documentation written by the engineers who build the system: FDS, HDS/SDS, IQ/OQ, traceability and Part 11 assessments.
Learn more 06Breakdown support, troubleshooting and annual maintenance contracts for PLC, drives and SCADA, on site or remote.
Learn moreOur engineers work on sterile and oral-solid process equipment every week. We understand the process each machine runs, the failure modes, and what QA will ask about.
Cresco designs, deploys and supports AVEVA InTouch HMI and System Platform applications, and engineers B&R automation and motion systems, for regulated manufacturing. The same team writes your PLC code.


Our project flow follows the GAMP 5 lifecycle, so the documents line up with your change control and qualification steps.
A selection of current and recent work. Client names are kept confidential on project details; references are available on request.
End-to-end freeze dryer support: retrofits, control panel upgrades, Windows, PLC and SCADA upgrades, mechanical upgrades, TXV to EEV/ETV conversions, compressor upgrades, SQL Server/SSRS cycle reports and AMC.
Modified the SCADA application for a purified-water and distribution system at an injectables facility, including screens, alarms, reporting and change-control documentation.
Full documentation suite and PROFINET integration of servo drives with a Siemens PLC for a pharmaceutical hot-melt extruder, covering alarms, interlocks and qualification documents.
Replacing an ageing IPC/SCADA on a roll compactor with a supported platform built on AVEVA InTouch HMI, with recipes, audit trail and reporting.
PLC upgrades, breakdown support and field service reporting for formulation plants of a leading Indian pharmaceutical company.
Automation, validation documents and proposals for process equipment at a major Indian vaccine and biologicals manufacturer.
Data integrity and computerised-system expectations are tightening. We track the guidance so your systems meet current expectations when they are commissioned.
The FDA’s CSA guidance moves effort from scripted documentation to risk-based testing of the functions that affect product quality. We size our OQ effort the same way.
The draft revision of EU GMP Annex 11 places more weight on audit-trail review, identity and access management, cybersecurity and supplier oversight. A new Annex 22 on AI was drafted alongside it. Our designs already cover these areas.
OPC UA, historians and IEC 62443-style segmentation let you use plant data for reports and dashboards without exposing the control network.
From global generic manufacturers to vaccine makers and hospitals, our clients return to us for upgrades, AMCs and new projects.
