Rising head pressure at constant load — a fouled condenser, priced.

No client is named, no logo is shown and no figure here was measured at any site (R2).

How it went.

Every study on this site runs the same four beats, in the same order.

  1. 01

    Alert

    A fouling condenser makes the compressor work harder for the same cooling. It never trips an alarm. It just quietly raises the electricity bill.

  2. 02

    Cost

    Head pressure vs. load — The ratio drifts long before the system trips on high pressure.

  3. 03

The problem

A fouling condenser makes the compressor work harder for the same cooling. It never trips an alarm. It just quietly raises the electricity bill.

What would be installed

  • Head pressure transducer on the refrigeration circuit
  • Compressor current monitoring
  • Ratio trending with a cleaning threshold

What changes

Before — A cleaning schedule based on the calendar After — A cleaning schedule based on the measured penalty

The number

Head pressure vs. load — The ratio drifts long before the system trips on high pressure. Illustrative scenario, not a client result. Figure is representative, not measured. [TOM-REVIEW]

In one line

Maintenance on condition, not on the calendar — and a number attached to the delay.
