Small Ammonia Leaks Become Big Problems When Nobody Sees Them

Most ammonia leaks do not start with a visible cloud or a system shutdown.

They start small.

And in systems using water or glycol as a secondary refrigerant, these leaks can remain unnoticed for a long time while gradually affecting system performance and increasing the risk of costly repairs.

The challenge is simple:

How do you detect ammonia before the leak becomes a problem?

Our pH Sensor is designed to do exactly that.

Detect Ammonia Where It First Appears

In indirect refrigeration systems, even a small ammonia leak into the water circuit changes the chemistry of the medium.

This change affects the pH value long before other symptoms become visible.

Installed downstream of the ammonia evaporator, the sensor continuously monitors the water or brine circuit and detects pH changes caused by ammonia contamination.

This provides an early warning signal that allows operators to investigate and correct problems before they escalate.

Because finding a leak early is always less expensive than repairing the damage it causes later.

Designed for Long-Term Stability

Traditional pH sensors often require frequent maintenance and calibration.

In industrial refrigeration environments, this creates unnecessary service requirements and increases operating costs.

Our sensor uses differential measurement technology, which significantly improves stability and extends sensor lifetime.

The sensor element is designed for a minimum operational lifetime of two years under normal operating conditions and requires less frequent calibration than many conventional pH measurement technologies.

The result is more reliable monitoring and less maintenance.

Built for Industrial Refrigeration

A pH sensor used in refrigeration must withstand more than laboratory conditions.

It must operate reliably in demanding industrial environments where temperature fluctuations, vibration and continuous operation are part of daily life.

The sensor operates across temperatures from -15°C to +95°C and is designed specifically for industrial refrigeration applications.

This ensures stable performance even under challenging operating conditions.

Simple Integration into Existing Control Systems

Monitoring should not add complexity.

The sensor operates as a standard two-wire transmitter and provides a 4–20 mA output corresponding to a pH range from 0 to 14.

This allows straightforward integration into PLCs, SCADA systems and existing control platforms without requiring special interfaces or communication protocols.

Operators receive continuous pH measurements and can implement alarm functions based on their own operational requirements.

Better Leak Detection Through Better Measurement

Ammonia leaks into water and brine systems are often difficult to detect through visual inspection alone.

By continuously monitoring pH values, operators gain an additional layer of protection that helps identify problems before they affect system performance or develop into larger failures.

Because the most effective leak detection strategy is not reacting to leaks.

It is finding them while they are still small enough to fix easily.
