Although CP4000H is a single-tank heater-cooler device, in heating mode, since only water in the inflow line and water pump is heated, it is possible for water at 1°C to rise to 36°C within 5 minutes. 

For improved safety and prevention of dry heating, water flow sensors are installed inside the tank and on the inflow line. Heating and cooling will stop if no water flow is detected. 

The controller is detachable and can be positioned closer to the operator for improved visibility and efficiency. The controller also features an LCD panel for improved visibility and operability. Water circulation state can be confirmed with a single glance from the colors on the screen.
