Pressures
Temperatures The blend set temperature is factory set at 43°C
but can be reset onsite if required.
Note: : For general safety, hot water inlet temperature should be maintained between 60-65°C. The mixing valve can accept temporary excursions above 85°C (however this is not recommended).

Rada 215 Series Mixing ValvesThe Rada 215 thermostatic mixing valves (TMV) feature the Radatherm sealed-for-life service free cartridge.
This significantly reduces the service
time and spare parts required for annual
maintenance. The Radatherm cartridge
only needs to be replaced every 5 years, or
earlier as per risk assessment.
These valves are approved to Australian
Standard AS 4032.1 and are NSW Health
approved.

Rada 320 Series Mixing ValvesThe Rada 320 thermostatic mixing valve (TMV) has a maximum flow rate of 120 L/min which enables a large number of outlets to be served by the one mixing valve.
Featuring the Radatherm sealed-for-life
service free cartridge the service time
and spare parts required for annual
maintenance is reduced. The Radatherm
cartridge only needs to be replaced every 5
years, or earlier as per risk assessment.
These valves are approved to Australian
Standard AS 4032.1 and are NSW Heath
approved.
The inlets can be orientated to suit the
installation and 2 outlet ports are available
as required.

PressuresFor optimum performance, dynamic
inlet supply pressures should be nominally
balanced to within 10% of each other
during flow.
Max. pressure loss ratio should not
exceed 10:1 in favour of either supply
during flow. See product manual for
further information on pressure loss ratios.

RadathermRada 215 & 320 TMVs include Radatherm,
a service-free, sealed-for-life cartridge that
is a low maintenance solution for accurate
mixed water temperature control.
Factory assembled, tested and sealed
for durability and reliable performance,
Radatherm makes annual preventative
maintenance simple and efficient,
substantially reducing the time required to
service individual TMVs.
We recommend that the cartridge is
replaced every 5 years unless an operating
conditions risk assessment determines
more frequent replacement.
Benefits of Radathermn Self-contained, service-free cartridge
for low maintenance
n Polymer cartridge materials prevent
scale build-up and corrosion
n Quick and easy cartridge replacement
n Reduced spare parts stock holding
