Refrigerant leaks and liquid slugging are rarely isolated incidents.

They are often early signs of problems that can lead to costly downtime, reduced efficiency, damaged equipment and safety risks. The question is not whether you can detect these issues. The question is how early you detect them.

At HB Products, we develop sensors that help refrigeration systems respond before small issues become major failures. From leak detection in machine rooms to compressor protection and monitoring of cascade systems, our solutions provide direct insight into what is happening inside the system.

Early Leak Detection Protects More Than Equipment

A refrigerant leak affects more than system performance.

It can compromise safety, increase operating costs and, in some applications, put products and production at risk. Detecting leaks early allows corrective action before the consequences escalate.

Our gas alarms continuously monitor refrigeration systems for small refrigerant leaks in areas such as machine rooms and cold storage facilities. The sensors are available for a range of refrigerants, including CO₂ and ammonia, providing reliable detection where it matters most.

Monitoring Ammonia in Water and Brine Systems

Ammonia contamination in water and glycol systems is not always immediately visible.

Our pH sensors are designed to detect ammonia concentrations above 100 ppm in water and glycol brines, helping operators identify leaks before they develop into larger operational challenges.

In applications involving high-pH antifreeze solutions or seawater, larger leak volumes may be required for detection due to the properties of the medium. Understanding these conditions is essential for reliable monitoring and system protection.

Compressor Protection Starts Before the Compressor

Compressor failures caused by liquid slugging are often expensive—and preventable.

Our compressor protection sensors continuously measure liquid content in the suction line ahead of the compressor. Instead of relying on indirect calculations, the sensors provide direct information about the presence of liquid, allowing operators to react before damaging amounts reach the compressor.

The result is improved reliability, reduced maintenance costs and longer compressor lifetime.

Protecting Cascade Systems from Hidden Risks

CO₂/NH₃ cascade systems offer significant advantages, but they also introduce unique challenges.

One of the most critical is CO₂ leakage into the ammonia circuit. When this occurs, ammonia carbamate can form and create blockages that restrict flow, reduce performance and, in severe cases, cause system failure.

Our monitoring solutions help identify these conditions at an early stage, allowing intervention before deposits affect system operation.

Better Decisions Through Better Measurement

Many refrigeration failures develop gradually.

The difference between stable operation and unexpected downtime often comes down to how quickly you identify changes inside the system.

By measuring leaks, liquid carryover and contamination directly, operators gain the information needed to improve safety, protect equipment and maintain reliable system performance.
