In their quest for a reliable solution to manage oil and refrigerant in their ammonia chillers, Mayekawa Nordic turned to HB Products and our HBSR switch.
Our Defrost HBDF Sensor voted Best innovation in Industrial Refrigeration 2022 by the France Trade Show SIFA | Salon du froid et ses applications
The use of heat pumps has increased along with the green transition to environmentally friendly forms of energy. Many large air to water heat pumps are already installed where the energy in the air is used to evaporate a refrigerant either directly where the refrigerant is present in the evaporator or indirectly where a frost-proof one circulates brine.
The A2 will now be replaced by A3 to provide a better product and simplify our product program. The A3 provide a better accuracy especially at elevated temperatures and has been used for heat pumps for some years.
A new technology makes it possible to build a cold store with both a low refrigerant charge and a small energy consumption.
From end of September 2020 all the switches with the circular electronic unit will have a built in heater.
All level transmitters with integrated cable for direct control of Electronic Expansion Valves will now have analog 4-20 mA output to PLC or main controller unit.
For level and HBX Vapor Quality Sensors with cable for direct control of valves the maximum current output is now increased from 1A to 2A.
HB-level switches are upgraded to IP66 for outdoor use with new electronic unit/housing and union thread / threaded connection. The product update will be ready for the market in the fall of 2020.
The HBX Vapor Quality Sensor has now become a mature product - easier to install and use for all common refrigerants.
From 1st of March 2020 we can proudly present a new improved HBPH-MK2-LT sensor specified for low temperature applications.
