Control Panels for Pharmaceutical & Biotech

Sterling Made builds UL 508A industrial control panels for pharmaceutical manufacturing, biotech research facilities, and life sciences production environments.

Massachusetts has the largest life sciences cluster in the United States, with over $460 million in active construction projects including AbbVie, Moderna, and Alnylam facilities — each requiring dozens to hundreds of control panels.

Panel Types

Clean utility control panels — WFI, purified water, clean steam generators, CIP skids
HVAC and cleanroom monitoring — AHU control, differential pressure monitoring, temperature/humidity, room pressurization cascade
Process skid control panels — Bioreactors, chromatography, TFF, fill-finish equipment
Environmental monitoring — Particle counters, temperature, humidity, differential pressure across classified areas
Utility monitoring and control — Compressed air (oil-free), nitrogen generation, chilled water, hot water

Example Project

Purified Water System Control Panel

A biotech manufacturer expanding a Greater Boston facility needed a control panel for a new purified water system — multimedia prefilter, carbon filter, water softener, RO unit, EDI polisher, storage tank, and UV sanitization loop. Sterling Made built a 480V/120V panel in a NEMA 4X 316L stainless enclosure with an Allen-Bradley CompactLogix L33 PLC, 32 DI, 16 DO, 12 AI (4-20mA), and three ABB ACS580 VFDs. Ethernet/IP to the facility's PlantPAx DCS. Full IQ/OQ documentation support and FAT hosted at our Massachusetts facility.
