Frost-Free ASWH 3P

Product  Introduction

Detian frost-free ASWHs equipped with our national patented frost-free system can operate continuously and efficiently in the cold and humid region with no frost forming.

Highlight of Product


High Heating Efficiency

The product can continuously operate in high heating efficiency in cold and humid winter. Unlike the conventional ASWHs, these equipments during operation do not need to stop for pressure release, nor for four-way valve direction changing, or lowering hot water temperature, or accessorial electrical heating. No freeze on heat exchanger either.


High Efficiency and Energy-Saving

Comparing with conventional frost-free heat pump products, Detian's frost-free ASWHs can save 35%-40% energy and the heating temperature can reach up to 70℃.


Energy Fusion

The equipment set employs energy fusion technology, transforming the residual heat in the system to renewable energy. With this technology, the product operation is more stable and the energy efficiency is increased by 25%. 


Protection Devices

Refrigerant system in this equipment employs national patented technology, eliminating the liquid on the compressor when operating in low temperature condition, and in turns largely extend the life of compressor.


Safety Protection System

Up to 22 safety measures are employed in the product (average 12 safety measures employed in the industry), including the exclusive automatic detection control system for preventive detection and protection prior to ASWHs operating, and the other one detecting and protecting the equipment during the operation.


Easy Maintenance

The control system is capable to indicate the information when an error is found, with which, our after-sales service can promptly identify the problem and provide the right solution.
