Besides 50hz heat pump models, OSB had improved and 60hz heat pump to meet difference market demand.
The 60hz heat pump air to water with evi compressor of 16kw is new arrival.
In other words, it is the evi heat pumps but with 60hz.
Talking about EVI heat pump, Our evi heat pump air to water not only working till minus 25 deg c, but offer stable heating capacity and COP at that condition.
As there is EVI special fan motor suitable for low ambient temp. And heating belt on the chassis and under the blue fine condenser to help to melt the ice more quickly.
What’s in additional, a few of drain holes for the condensation water, make it fast and easy to drain out all water after melting.
The last but not least, craft heater on the compressor to help to compressor feel warm and able to working stable even at temp drop to minus 25 deg c.
You may question how can we test the 60hz heat pump air to water evi?
As the power supply in China is 50hz, not 60hz.
That’s a good question, you are right, our normal power supply is 50hz.
However, with OSB new arrival testing lab with inverter testing machine,
it can simulated to air temp as -25 deg c to make sure the tested heat pump with best performance at chilly area, and make sure the 60hz heat pump models can be well testing in 60hz supply and match the best heating/cooling capacity.
There were samples of 60hz heat pump air to water evi exported last few months.
And we are waiting feedback from the clients to improved it.
