OSB is a professional heat pump manufacturer founded in 1999, with rich experience in manufacturing and exporting air to water heat pump products. O.S.B. have born in 2014, dedicated to provide the highest quality of service and most demanding products available in the latest market. Our products can be OEM&ODM, we can design and produce the heat pump as your requirement, and the package can be your design.
Now，its new EVI air source inverter heat pumps for cold area heating and cooling. was born.
Low Ambient Temperature (-25℃~43℃) :
Because of the Enhanced Vapour Injection (EVI) technology scroll compressor, EVI air source heat pump can work stably in the low temperature condition.
Improved Heating Efficiency:
When the temperature reaches the set value, it will automatically change to low frequency operation mode, and the effect of energy saving is remarkable.
Reduced Defrosting Time:
The frequency converter enables the EVI inverter air source heat pump to automatically adjust the compressor operating frequency according to the ambient temperature. When the unit needs defrosting, it will use high frequency operation, which greatly reduces the defrosting time and thus improves the heating efficiency.
Constant Indoor Temperature:
OSB EVI inverter heat pumps can operate in the range of 50Hz to 60Hz, output and utilize heat energy according to the environment and the set temperature. Inverter heat pumps can maintain the set temperature with a lower operating frequency after reaching the set temperature and will not frequently start or turn off.
