Standard product features
Operation:
• The Rada Thermotap-3S has a 100 mm long, single lever control for sequential operation from Off through cold (minimum), and warm to hot (preset maximum).
• The flow rate is limited to 4-6 litres/minute with flow regulators fitted.
• The Rada Thermotap-3L has a 150 mm long lever control.
Tap hole:
Ranging between 26 mm to 36 mm.
Connections:
Inlets: 15mm or ½" BSP male and 10 mm stainless steel flexible hoses (supplied).
Pressure/ Flow rates:
• Minimum dynamic supply pressure: 0.2 bar.
• Maximum pressure loss ratio: 10:1 (in favour of either supply).
• Maximum static pressure: 10 bar.
• Note: Both hot and cold pressures should be nominally equal.
Temperature range:
• Factory pre-set maximum blend temperature: 41°C.
• Minimum temperature differential blend to either supply: 10°C.
• Optimum temperature control range: 35–45°C.
• Minimum cold water temperature: 5°C.
• Maximum hot water temperature: 85°C
Note: The thermotap can accept temporary temperature excursions above 85°C without damage, however, operation at such elevated temperatures is not recommended. For safety reasons it is recommended that the hot water storage temperature is maintained at between 60°C and 65°C in ablutionary applications.
The full specification performance outlined below is achieved with a blend set between 35°C and 45°C, supplies of 15°C cold and 65°C hot with nominally balanced pressures.
• The blended water temperature is maintained within 2°C with a 10°C change in the hot or cold supply.
• The blended water temperature is maintained within 2°C when either inlet pressure drops by up to 50%.
• The 'Thermostatic' sensor effects a shut down to seepage within 2 seconds if either supply fails, providing the blended temperature differs from the inlet supply temperatures by at least 10°C.
• The tap will maintain control with a pressure in balance of up to 3:1 between hot and cold supplies.
Materials:
• Body: DZR brass chrome plated.
• Levers: Chrome plated zinc casting.
