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 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.

Main data:

• DN 15

• kVS 2,4; 3,0 m3/h

• PN 16

• Setting range: 45 ... 65 °C

• Temperature:
Circulation water 2 ... 120 °C

• Connections:

- Union nut

- External thread

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.

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.
