1. Economic and energy saving:it costs low for initial installation, small in size and space-saving compared withh fuel gas an fuel oil.The outlet water temperature can be adjusted flexibly, with the hightest up to boiling point 100°C and drying temperature up to 80°C. It can partly replace  boilers because of its high thermal efficiency and low operation cost which equals to one half of fuel oil and fuel gas and one third of electric heat recovery.It greatly saves energy and produce additional fresh and drycool air.
 
2. Safe and stable:no direct contect between water and electricity to avoid risk of electric leakage;low noise,electric drive, intelligent control,free setting and no staff is required to stand by during opration
 
3. Ecological-friendly:there will be no discharge of pollutionn such as waste gas.water or residue during running.It is ecological-friendly inn energy-saving and meets the requirements of environmenta protection
 
4. Reliable and durable:the technology of heat pump is mature and stable, with various protective measures such as protections for overlode,phase failure,high-temperature,and high pressure.In daily maintenance,only cleaning or changing of filter screen is needed. The operating life is over ten years
 
5. Widely application:water discharged from high-temp. Heat pump is up to 100°C and can be widely applied industries such as factories,schools,hotels and textile printing and dyeing etc.
