1. Features
Titanium heat-exchanger
Titanium heat-exchanger has highly resistant to corrosion.
High strength and durability, pressure test at water side (0.5MPa, water temperature 45°C,
60,000 times).
No need secondary heat-exchanger, reduce the cost of installation.
Because of titanium heat-exchanger of anti-corrosion, the water system of HPWH can be
directly connected with poor.
Without secondary heat-exchanger, it is can improve the efficiency of whole system.
Easy operation and automatic control, the system can be controlled simply through the wired
controller with LCD display which is installed in the unit.
Environment friendly refrigerant R410A is used. No discharge of poisonous gas. No pollution to
atmosphere and environment.
Automatic start-up and shutdown, automatic defrosting. Save much extra operation.
Within temperature range from -7 °C to 38°C, it will not be affected by night, overcast sky, rain
and snow.
Multi-temperature sensors always monitor the unit operating status.
