Pfizer case study

Magcat stopped scale formation at Pfizer’s Dagenham plant, eliminated weekly shutdowns, and delivered a fast ROI.

Client: Pfizer
Region: United Kingdom
Application: Heat exchangers on multi-stage compressors
Sector: Pharmaceutical
Product: Magcat water conditioner

Pfizer is a global biopharmaceutical company with a UK plant in Dagenham, London. Multi-stage compressors at the site relied on heat exchangers that were prone to heavy scale build-up, even with chemical inhibitors in use.

The challenge

Heat exchangers scaled rapidly, causing efficiency losses

Weekly shutdowns were required for chemical cleaning

High costs from chemical purchase, labour, and lost production

Health and safety risks associated with regular handling of chemicals

The solution

A 3” Magcat was installed on the water supply line to the heat exchanger. Engineers tracked performance following installation.

Results

Scale formation was eliminated

Weekly shutdowns for chemical cleaning no longer required

Annual savings of around £13,000 in labour and chemical costs

ROI achieved in just six months

Ongoing benefits: higher efficiency, extended equipment lifespan, reduced health and safety risks, and lower environmental impact
