Product Features

1. Wide Applications
This series of products include fresh air type, return air type, heat pump type, cooling only and heat pump type, constant temperature and humidity type (can be customized) and other series. The heat pump type can be used in places with comfort requirements.
2. High Efficiency Direct Expansion (DX) System, Energy Saving and Low Power Consumption
The unit adopts a direct expansion high efficiency circulation system that directly exchanges heat between refrigerant and air. There is no intermediate medium of indirect heat exchange like chilled water system, which helps reduce power losses, the energy utilization is 10% to 15% higher than that of the chilled water air conditioning system. In addition, each unit has multi-level energy regulation, which can automatically increase or decrease the load to adapt to the load change. The unit can run with 100% fresh air in transitional seasons, this is energy-saving and low power consumption, and reducing operating costs.
3. Unique Structure, Dedicated For Outdoor Use
Integral unit design, compact structure, can save investment and make installation work easy. The whole process of automatic spraying line processing and spraying of the structural parts of the unit, aluminum alloy frame, high-pressure foamed color steel thermal insulation panel and special outdoor type unique rain-proof structure design, all these ensure the unit can be anti-corrosion, anti-rust, no rain leakage when used outdoors.
4. Safety Protection
Compressor inverter starting protection, compressor shortest running time protection, filter detection, high voltage protection, low voltage protection, compressor current overload protection, fan current overload protection, power protection (phase loss, reverse phase, overvoltage, undervoltage, phase-to-phase Balance), compressor discharge temperature is too high protection.
