  • Branded componenets, heart compressor as top one America scroll Copeland, Japan saginomiya four way valve, Emerson expansion valve.

  • Environment friendly HCHF refrigerant  as R410A / R407C, 

  • Quick-mind LCD controller, one touch ON enjoy automate heating and hot water, timer ON/OFF function available.

  • Auxiliary electric heating control possible.

  • Intelligent defrosting technology, evaporator as finned tube heat excahnger with big air flow, its wave shape design efficiently reduced get frosting in winter, to the climate of dry air, adpoted “time + temp difference “defrosting control technology, defrosting in time and clean.

Technology changes life!
We concern your living feeling, also concern your electricity bill

Branded components

  • Mature design
    Adopt “Solkane 5.0” software to calculate heating, “Airsoft” software to calculate heat exchanger design, “system Design Simulator” to calculate cooling system capacity, to assure system match reasonable.

  • Reliable technology
    Nitrogen filled protection when welding, high pressure Nitrogen to keep pressure and electronic halogen detection for assure system no leaking.
    Pipe take shock absorber design, and take protector to assure pipe never get worn out.
    Wire lines atke insulation protection, assure never because of wire aging and get short circuit.

  • Reliable test
    Before delivery, unit has get through full test for safety, high temp, low temp, defrosting condition, assure unit run safely, stable and high efficient.

  • Suppress frosting and defrosting technology
    Supress frosting: Evaporator takes big air flow design, special allocate technology assure every refrigerant loop the same flow.
    Somre units adopt single row heat exchanger, improved heat exchange efficiency and decreased frosting form speed, adopt wave type high efficient fin, to assure frosting won’t block flow.
    Defrosting technology: Adopt PID defrosting technology of “time + temp difference change rate”, to assure defrosting in time and clean.

  • Refrigerant pressure control technology.
    Adopt patent produced refrigerant pressure buffer system, making the refrigerant system keep stable at different ambient temp and water temp.
