Top-of-the range RAS-D2 radiator thermostats come with chrome-plated, brass valve bodies and a choice of sensors either in subtle white with chrome styling or in stunning all-chrome. This latter finish, in particular, compliments many of the latest designer radiators and towel rails.
All valve bodies for these controls are reversible and bi-directional, incorporating the Danfoss patented ‘Revolver’ flow-selectable feature to ensure trouble-free installation without any risk of water hammer. In angle and straight patterns, they have a ½” BSP (R½”) tail piece connection to the radiator and include 8mm, 10mm and 15mm compression fittings to connect the valve to the pipework.
Room temperature is controllable between 8°C – 28°C and the sensor head carries ‘Frost Protection’ and ‘Positive Off’ setting positions. Convenient combi packs containing sensor, valve body and lockshields are available.
The Danfoss Randall RAS-C2 radiator thermostat has a stylish white sensor head and will impart a quality feel to many modern bathrooms. Many of the features of this control are the same as those of the RAS-D2, offering the same setting range, Revolver flow selectable device, Positive Off and Frost Protection settings, etc., with 8/10 and 15mm valve sizes in angle and straight versions. Sensor mounting requires no tools; it just needs to be pressed onto the valve body and its clamping ring tightened by hand.
RLV-D lockshield valves are manufactured to extremely high standards and finished to match the Danfoss range of radiator thermostat valves. They are available in 8/10 and 15mm angle pattern as well as a version incorporating a 10mm push-fit elbow.
An accessory pack to convert the valve into a conventional wheelhead valve is also available.
Apart from these mainstream controls, Danfoss Randall also offers a specialised range of TRVs intended for designer radiators and towel rails in bathrooms. This RA-URX luxury range is available in white or chrome, and has an innovative self-sealing valve-to-radiator connection that enables seamless, elegant and easy installation. Its compact design allows the sensor to be mounted beneath the towel rail, parallel with the wall, thus reducing the risk of accidental knocking and damage.
The RAX radiator thermostat is a room sensor developed for controlling bathroom temperatures where the towel rail is the primary source of heating.
The RTX return temperature limiter, which monitors return temperature, is ideal where the towel rail is the secondary source of heating and keeping the towel rail warm, irrespective of room temperature, is a priority.
The VHS valve integrates the functions of radiator thermostat, lockshield valve and connection system into one compact, easy-to-install unit. With versions incorporating bottom or back connections, these valves can be used together with RAS-C2 or RAS-D2 sensors. There is also a snap-on cover to enhance their aesthetics.
