Angle Rod Housing - Vapor Quality Sensor

Category: HBX-DX/C-SS - ATEX/IECEx Certified

HB products has developed the unique vapor quality sensor, which is the only sensor able to directly measure the liquid content of liquid in the evaporator output. The sensor works both in pump circulated and DX systems and can optimize the efficiency and capacity to a new level.

Evaporator control
The optimal evaporator is not filled with liquid refrigerant like you often have in pump circulated refrigerant systems with circulation ratios above 1.5. The optimal evaporator is not dry like a lot of superheat-controlled evaporators.
By measuring the liquid content in the evaporator output and using this measurement to control the liquid feed.

Most refrigeration systems operate most of the time in part load and especially during part load the efficiency is typically rather poor and can be optimized significantly. Pump circulated systems fills the evaporator with liquid which reduce heat transfer by 50 % and increases the pressure loss which increase energy consumption. For pump circulated systems an energy saving of minimum 20% is typical for optimized systems, and much more on systems without circulation control.

In DX systems a larger part of the evaporator is used for superheating and the superheat is increased which reduce capacity and increase the power consumption dramatically. We have documentation showing an energy saving of 20% during full load and 50% during part load for a DX ammonia system. Link to the documentation.

Angle Rod version
The Angle Rod version is suited for smaller systems and is made in stainless steel. It accepts flow in both directions and is suited for all common refrigerants. 
The sensor comes with reductions to compensate for a restricted flow area as standard. The sensor is made in stainless steel and can be butt welded (TIG) or brazed into the system. The sensor element can be removed and cleaned if necessary. The sensor is available from ¼” to 1” pipe size.

Intrinsically Safe design
Intrinsically Safe (IS) sensors are designed and wired to work on such a low current and voltage that it cannot possibly ignite flammable material. By limiting the energy available within the defined hazardous area, electrical equipment can operate safely even amid hazardous mixtures of gasses.
