Danfoss IHPT Valve 90 KVS 3.0 – 003L3815 / 99008002

Danfoss IHPT Valve 90 KVS 3.0 – 003L3815 / 99008002

The Danfoss IHPT Valve 90 KVS 3.0 is a flow-compensated temperature controller designed for controlling instantaneous domestic hot water production through a plate heat exchanger. This genuine Danfoss IHPT controller is commonly used within compatible Danfoss and Termix heat interface units (HIUs). The valve combines temperature regulation with an integrated differential pressure controller, allowing the IHPT to respond to both domestic hot water demand and system conditions. During a domestic hot water draw-off, the IHPT opens and regulates primary flow through the heat exchanger to maintain the required DHW temperature. When the draw-off ends, the valve closes. Product Details Manufacturer: Danfoss Product: IHPT Valve 90 Danfoss Part Number: 003L3815 Alternative / HIU Reference: 99008002 Nominal Size: DN15 KVS Value: 3.0 m³/h Pressure Rating: PN16 Temperature Setting Range: 45–65°C Application: Domestic hot water control Controller Type: Flow-compensated temperature controller with integrated differential pressure control What Does the Danfoss IHPT Valve Do? The IHPT is a self-acting controller developed for instantaneous domestic hot water production. It regulates the primary heating-water flow through the HIU plate heat exchanger according to domestic hot water demand and temperature. The integrated design combines flow and temperature regulation with differential pressure control, helping provide stable domestic hot water temperatures across varying draw-off conditions.
