OSO DELTA COIL DC
Ideal for boilers with ultimate energy efficiency - ErP A
DELTA series is the most efficient hot water cylinder available, uitilising unique Vacuum Panel Insulation and is the only full range of ErP* A-rated cylinders available from 120 - 300 L. DELTA boasts 30 - 50% higher efficiency than rivals, translating into direct SAP gains. DELTA series can save enough energy to pay for the entire cylinder over its lifetime. Delta has holiday and anti-legionalla finctionality. * Energy-related Products Directive – 2009 / 125 / EC.
DELTA COIL— DC is elegant and functional in its design, delivering class-leading insulation characteristics and is compatible will all boilers, using smooth piped, scale-resistant heating coil. The DC units can be controlled either via its own thermostat or using a thermistor probe. DELTA uses a high performance fully flooded design, with separate expansion vessel, and an ultra-grade INCOTEC immersion heater as back-up above the heating coil, providing maximum operational safety. A complete set of inlet control valves comes standard. DELTA COIL is also supplied with a digital thermostat compatible with both S & Y plan systems which displays the water temperature and offers holiday and anti-legionella modes..
