Precise Measurements with Accurate Sensor Technology
HB Products specializes in designing and developing second-to-none sensors for refrigeration and heat pump systems. All our sensors are engineered to withstand harsh environments and extreme temperatures, ensuring accurate and continuous measurements. How do they work? Find out in the animations below.
How Do Our Liquid Level Switches
and Liquid Level Sensors Work?
Ensuring Longevity with a
Practical Split Design
By implementing our Liquid Level Switches, Liquid Level Sensors, or a combination of both, you get essential insights and a dependable solution to effectively monitor and control your refrigeration system.
Our sensors and switches have an efficient split design, making them not only user-friendly for everyday operations but also easy to maintain. This design choice significantly enhances the durability and longevity of our devices.
To ensure the optimal solution, our sensors have been designed to handle all types of liquids.
This means, whether you use natural refrigerants like ammonia, propane, or CO2, or need a sensor for synthetic refrigerants such as HFCs, CFCs, or HFOs, HB Products has a sensor designed to accommodate your requirements.
A Simple and Cost-Effective Approach to Automatic Oil Return
Our oil ejector is propelled by hot gas and used for returning oil from a low position up to the suction line or compressor. It is typically with two solenoid valves, which can be controlled directly by a HBOR/C or HBOC/C making up a simple oil return system.
HBOR/C is used for ammonia systems where you have liquid ammonia or gas on top of the oil. HBOC/C is used for all other systems where you only have gas on top of the oil. Both switches have a direct control output for the valves.
For ammonia systems the oil return can also be controlled from a HBOR or HBSR providing input to a PLC or similar.
The ejector is a cost-efficient and durable solution for oil return, which does not need maintenance.
The ejector works with hot gas up to 130 bar (1885 psi), and it can handle liquid/hot-gas temperatures from -60°C to +150°C (-76°F to 302°F).
The oil pumping capacity depends on the viscosity and potential pressure loss between the ejector and the suction line.
