DC Inverter heat pump Advantages:

2.E-heater, diverter valve,water pump,and expansion tank can be included

Panasonic/Toshiba/Sanyo Inverter Rotary compressor and ECO R32/R410 refrigerant for max heat capacity and less
refrigerant, large volume of latent heat from the air via evaporator in coldest season.
B.Ultra frequency conversion technology
Based on the principle of proportional relationship between motor speed and input frequency of working power supply: n = 60f(1-s)/p and changing motor speed by changing working power frequency of the motor, it adopts AC-DC-AC power conversion technology, relying on our powerful control system with PWM generation ability, integrate V/F, vector control (VC) and direct torque control (DTC) to achieve control method of variable frequency PID calculus, mainly drive variable frequency by way of PWM synthesis drive, fully integrate power, electronics, microcomputer control and other technologies.
C.Advanced Carel Operate System, ultra intelligent
Especially superior heat dissipation circuit board design, longer service, over 3 time of other brand's, simple click and fully
play the characteristics of DC inverter frequency conversion system to achieve overlocking performance.
D.Multi-speed mute fan motor

ROHS fan blades, ultra-low noise, durable & reliable, constant max air flow to satisfy heat supply.
E.Soft-start and soft-shutdown
Protecting both electrical system and all key parts, such a EEV, SANHUA 4-way valve, LG AC contactor & other World famous brand components ensure heat pump device 2-3 time longer service by

1) making output torque of the motor meeting the requirements of mechanical system for starting torque, ensuring smooth acceleration & smooth transition, and avoiding destructive torque impact;
2) achieving both starting current meeting the requirements of motor's bearing capacity, and the insulation damage or burnout caused when it starts.

3) reducing both voltage sag range and the content of high-order harmonics etc.
F.High-tech shock-absorption all copper construction piping
High-accurate completely automatic silver welding, easy maintenance.
G.High-density protective jacket for minimum heat lost
Aviation class insulation foam with outstanding sound absorption.
H.Classic European outlook forming
Fashion taste, never out of time.
I.Portable compact design
Saving room for installation & operation.
J.Fast heating and cooling speed

Carel smart controller
