Alfa Laval Alfa P-Scale acidic CIP cleaner for heat exchangers (scale removal)
- Application: descaling and inorganic-deposit removal from plate heat exchangers
- Active substance: sulphamic acid + corrosion inhibitor
- Solution pH: acidic (typically 2-4 depending on concentration)
- Used with: Alfa Laval CIP unit or equivalent circulation pump
Where P-Scale is used
Plate heat exchangers (CB brazed range, M/T/TS gasketed range, AlfaNova) accumulate calcium carbonate deposits on plate surfaces over time — especially in DHW, DH, and industrial cooling circuits. Scale reduces the heat transfer coefficient (K), raises pressure drop (Δp), and cuts capacity. P-Scale dissolves inorganic deposits in a single 2-4 h service cycle without disassembly. After cleaning, use Alfa P-Neutra (SKU 3284000601) to neutralise the acid.

When to choose P-Scale
- DHW plate heat exchangers with noticeable capacity loss (≥15 % vs. new)
- Systems with water hardness > 10 °dH
- Routine preventive service every 3-5 years (CB/M range brazed)
- After exchanger operation with process water (cooling loops)
- Compatibility: all Alfa Laval plate heat exchangers with stainless steel / titanium plates; use caution with AlfaNova (SS brazing) — consult Alfa Laval

Frequently asked questions
Is P-Neutra required after cleaning?
Yes, mandatory. The acidic solution must be neutralised to pH 6-8 before sewer discharge. Alfa P-Neutra (SKU 3284000601) is added to the used P-Scale solution until neutral pH is reached.
Can it be used without a CIP unit?
Technically — yes, if an equivalent circulation pump with solution tank and heater is available. In practice — Alfa Laval CIP delivers controlled flow, temperature, and time, hard to match with an ad-hoc setup.
How to calculate required P-Scale?
Depends on exchanger volume and scale thickness. Typical dosing — 5-10 % mass concentration, circulated 2-4 h. Example: CB60 (~5 L internal volume) needs 250-500 g P-Scale. See Alfa Laval CIP guide for details.
Any health hazard?
Sulphamic acid is skin and eye irritant. Goggles, gloves, and lab coat are required. SDS supplied with delivery. Well-ventilated area required.
Suitable for gasketed exchangers (M/T range)?
Yes, if gaskets are EPDM or NBR (Alfa Laval standard). For special gasket materials (Viton, FEP) — consult Alfa Laval before cleaning.
