Reliable Safety and Leakage Detection for Challenging Environments
Early leak detection is vital to ensure safety and provide early warnings to avoid damage. HB Products offers a range of sensors designed to detect and protect your refrigeration system, stored goods, and employees. With Gas Alarms, pH Sensors, Compressor protection sensors, and Cascade Systems, you can find a solution to safeguard against liquid slugging, compressor damage, clogged systems, and costly repairs.
Achieve Safety and Compliance with Our Gas Detection Alarms
Our Gas Alarms are designed to detect small amounts of leaking refrigerant in areas such as cold storage facilities and machine rooms in order to provide early warning and avoid harm.
Our Gas Alarms come in different variations for both CO2 and ammonia that fulfill the requirements for gas leakage measurement in accordance with F-GAS regulation EU/517/2014.
The Gas Alarms provide easy integration as they can be configured with HB Tool. To further enhance safety, we offer a service kit to assist you with the maintenance.
Easy Brine Leakage Detection With a pH Sensor
Our pH Sensors are highly sensitive and designed to detect ammonia levels above 100 ppm in water and glycol brines.
To enhance durability, the pH Sensors have a protected universal flat-faced glass process electrode specially designed for tough applications.
Additionally, the pH Sensors have a “semi-flush” design to minimize the build-up of dirt on the probe and to ensure easy maintenance and low costs.

Prevent Damage to Compressors With Compressor Protection
Our Compressor Protection Sensors monitor the suction line in front of the compressor, providing an alert when liquids are detected, thereby safeguarding functionality and helping to prevent damage to the system.
We offer two versions: the Strainer Housing and the Rod Style.
The Rod Style Sensor must be installed in an elbow at the end of a horizontal pipe, at the bottom, where the liquid flows. The Strainer Housing Sensor is installed in an empty strainer housing and measures all the liquid flowing along the walls.
Cascade Leakage Detection in Liquid Ammonia
Cascade systems that use CO2 and ammonia face challenges with the leakage of CO2 into ammonia, and failure to address it promptly can cause significant downtime and damage to the entire ammonia system.
Our sensors are designed to detect and resolve such issues, ensuring the safety and longevity of refrigeration systems by triggering a digital alarm and increasing mA output when ammonium carbamate is detected in the ammonia.
For optimal detection, install the sensor at the bottom of the vessel. However, it can be installed in any position as long as it is covered by liquid ammonia.

What Is Your Potential Savings by Optimizing Defrosting?
Our Defrost Sensors ensure automatic defrosting based on the capacitive measuring principle, thereby eliminating excessive defrost cycles.
You can calculate your potential savings with our calculator. It is based on the conservative estimation of a 50% reduction, while the heat calculation is based on the Danfoss Liquid Drain method.
Systems using hot gas with pressure control and systems using electrical heating or hot water will consume more energy.
AB-Catering Eliminated Issues With Condensation and Continual Adjustments
For AB-Catering, their defrost cycles had caused serious issues for years, as they needed to adjust the cycles regularly, especially every time spring and fall rolled around.
In addition, they were having problems with condensation that dripped down on the conveyor belt and then froze to ice.
The solution to their problems was the Defrost Sensors from HB Products. Read the entire case study if you are curious about the solution and collaboration.
Store Ice During Off-Peak Hours with Our Ice Bank Sensor
Our Ice Bank Sensor is designed to optimize ice storage management in industrial and commercial refrigeration systems.
Using the capacitive measuring principle, the sensor accurately monitors ice build-up, enabling efficient ice storage during off-peak hours. This not only reduces energy consumption but also enhances system reliability by preventing excessive ice formation.
