+44 (0)844 571 1777 www.radacontrols.com

A group application electronic 'temperature controller' providing pre-mixed water for multiple shower and washing facilities where the hot water is supplied from a calorifier or stored hot water system.

The system can also allow both a high temperature circuit (Kitchens, laundries) and a low temperature mixed water circuit for personal washing purposes, to be supplied from the same low volume, high temperature type boiler.

The units are suitable for use in schools, hospitals, factories, hotels, sports and leisure, prisons and military barracks.

Standard product features

An electronic recirculating valve, incorporating a digital temperature display, suitable for multiple showers and washing applications.

The unit incorporates an electronic LED temperature display and is approved to BS 3456. The circuit temperature is controlled within ± 1.5°C of the set temperature.


Inlet and outlet - 1¼" BSP standard.


In precisely controlling the temperature of circulating mixed water, the Rada 32RMX performs two functions:

  • Mixes hot water with cold and recirculating the water to a safe, pre-determined outlet temperature when showers or washing points are in use.
  • Maintains the temperature in the circuit when no draw-off is taking place.


  • Supply voltage: 12V AC via a separate transformer PT 220 (220-240V).
  • Power consumption: 6 VA.
  • Electronic circuitry protection: 500mA quick blow fuse (fitted).
  • Cable entry: Base threaded to accept 20 mm conduit.


  • Maximum static pressure: 10 bar.
  • Maximum maintained pressure: 7 bar pressure loss.

Environmental conditions:

  • Ambient temperature range: 0-60°C.
  • Ambient humidity range: 0-100%RH.


  • Circuit temperature control: within ±1.5°C of the set temperature.
  • Digital temperature display accuracy: ±1°C within the range 30°C to 60°C.


  • Base: Nickel plated gunmetal.
  • Cover assembly: Aluminium.
  • Thermister cap: Phosphor bronze.
