Liquid Level Control Sensor- HB Series

HBDX is a new revolutionary, patent-pending sensor technology, and it is thus the first sensor in the world capable of measuring the relationship between vapor and liquid a refrigeration system. The sensor measures the degree of dryness, “X”, of the gas in the gas pipes, and the value is converted into a 4-20 mA analogue signal corresponding to “X”. The HBDX measures the dryness of the gas in the range X = 0.85…1.05.
The sensor is available in two variants, “Rod Style” for installation in a pipe elbow and “In-line” for welding into the suction pipe.

The sensor offers very precise measurements and provides instant read-outs of the gas quality, making it useable in most evaporators (plate, pipe, and air evaporators).
The sensor’s microprocessor also functions as a controller, enabling the direct control of a modulating motor valve, thereby bypassing the external controller or the PLC. The controller can be set up with all the parameters that are necessary for regulating a modulating motor valve or a stepper motor valve. The sensor is available with a cable for direct supply to and control of the motor valve, or as a sensor where the signal is sent to the external controller/PLC.

The sensor cannot measure actual overheating, but with proper installation and system design, overheating can be reduced or eliminated, thus leading to substantial energy savings.

Markets:
• Industrial Refrigeration

Features and Benefits:
• The vapor quality sensor allows for the operation of DX ammonia technology with minimal “superheat”.
• A dry suction pipe from the freezer minimizes loss of pressure in risers and provides increased flexibility of the pipe installation.
• 30 to 50 times less refrigerant required (ammonia systems), following the installation of the vapor quality sensor and the construction of the system based on DX technology.
• Measures vapor quality in refrigeration systems – measures the relationship between gas and liquid.

Application:
• Useable in most evaporators (plate, pipe, and air evaporators)

HBAC is used for detecting leakage in cascade systems. The sensor triggers an alarm if there is an NH3 leak in the CO2 part. A leak results in several hours of cleaning the pipes and heat exchanger. If a CO2 leak occurs in the NH3 part, salt crystals are formed. These salt crystals are very corrosive and lead to clogging of the parts. If the leak is not stopped in time, it can lead to extensive damage to
the heat exchanger, pipes, and pump.
The sensor detects even very small leaks.

Markets:
• Industrial Refrigeration

Features and Benefits:
• CO2 leakage detection in NH3 cascade heat exchanger
• Simple to install with a sleeve. A cost-optimized solution
• LED indication for power and alarm status
• Single Shared design that make it easy to install and diagnostics. The electronic part can be easily removed from the mechanical part by two small screws.
Applications:
• Detecting leakage in cascade systems

Defrost Sensor
HBDF is a simple solution for energy-optimal automatic defrosting of evaporators. It results in energy savings of approximately 10%, thus quickly recouping its cost. The sensor measures the thickness of ice deposits between the fins and sends a 4-20mA signal to the system’s PLC. The 4 mA signal is emitted when the evaporator is free of ice. The defrost point is set according to the evaporator type and the amount of moisture, and it is determined based on a visual assessment of the ice deposits on the evaporator.

The sensor can be installed in less than one hour, on both new and old evaporators. It can be installed when the system is in operation, and therefore, system shutdown is not necessary. The electronic part is mounted on the evaporator’s frame using 2 screws. The mechanical part consists of a thin Teflon-coated wire, which is installed between the fins of the evaporator. HBDF is available in 3 variants, with a 10m, 20m, and 30m wire respectively.

Markets:
• Industrial Refrigeration

Features and Benefits:
• Provides energy savings of up to 40 %, compared with conventional defrosting.
• Reduces downtime and minimizes system defrost time.
• Split design, which makes the sensor easy to install and service. The electronic part can be separated from the mechanical part.
• Can be installed on all evaporator types from all manufactures.

Application:
• Energy-optimal automatic defrosting of evaporators
