Self-acting controllers integrated to heat exchanger (PN16)
IHPT, Termix TPV – Flow-compensated temp. controller with ∆p controller built in (NO)
Description
IHPT
Self-acting controllers are designed to be integrated directly to heat exchanger. They are developed to control instantaneous heating of domestic hot water by means of heat exchanger.
The family of products offer full flexibility of different requirements regarding control performance and idle condition (no load conditions).
Innovative design enables simple, fast and reliable connection to heat exchanger and most important production of ultra compact and user friendly stations for heating of domestic hot water.
The capacity of controllers fully covers the needs of domestic hot water for flats, one family houses or dwellings and can be mounted to district heating network directly, to a block of heating systems or central located boiler system in a dwelling house.
The controller is connected to primary heating system as well as cold water system. To avoid risk of leaking from one media to the other the controller is equipped with double sealing. Between both sealings there is a bore to the outside of the valve. In case of leakage from one sealing the media can escape through the bore.
There are two different controller housings:
-original (IHPT)
-Gemina housing (Termix TPV)
Termix TPV controller has the same function as IHPT controller, but different (Gemina) housing.
Controllers have:
-WRAS approval,
-ETA VA approval.

In graph pressure drop on secondary side in relation to the secondary flow can be seen.

TC - thermostatic controller |
Quick suggestion:
If the max. flow rate on primary side is below 1 m3/h (1000 l/h) always choose kVS = 2,4 m3/h and if it is higher then choose kVS = 3,0 m3/h.
Measured for constant supply temperature of 75 °C and system differential pressure of 0,5 bar.
