The corrugated tube increases the heating surface and creates turbulence which gives a 20% better heat exchange than plain tubes.
The extra thickness of foam provides a cylinder with extremely low standing loses. |

Insatllation
Water Supply The unit will operate down to minimum Byelaw supply requirements but best performances are achieved above 25 L/M and 1.5bar dynamic pressure.
Flow Rates Up to 50 L/M if the supply is adequate
Expansion Chamber A potable water expansion chamber is supplied that is adequate for the storage vessel. If exceptional secondary circuits are fitted please contact us
Secondary Circulation A tapping is fitted as standard on larger vessels - please see technical specification chart
Boiler Compatibility Stainless Lite vessels can be fitted with oil, gas or electric boilers if a control thermostat and thermal cut-out is fitted. The system can be sealed primary or vented. Solid fuel boilers must not be used for any unvented cylinder.
Fixing The vessles are designed for vertical fixing. Installers must be competant (approved) to comply with Building Regulations G3 (England & Wales). Technical standards P3 (Scotland). Building Regulations to P5 (Northern Ireland) and all local regulations.
Plumbing Cold Feed / hot water draw-off / primary flow and return are provided with 22mm compression fittings with nuts & olives.
Cold Water Inlet Equipment The cold water control valve is factory set to give 2.25 bar. It is designed for high flow rates and is complete with line strainer, non-return valve and expansion valve set to 4.5 bar. |

Electrical
Indirect The electrical insatllation must conform to the latest IEE Wiring Regulations. The controls should be wired to the boiler, programmer etc in accordance with the chosen control scheme.
Direct The immersion heater(s) must be permanently connected to the supply through a double pole linked isolating switch with a minimum breaking capacity of 13A.
Specification
Storage Vessel Made from duplex grade stainless steel by the latest automatic welding processes. Post weld processes ensure the stainless corrosion resistance is maintained.
Primary Coil The tube is corrugated for greater strength and higher heat transfer. This construction allows 20% more heat transfer than plain tube and guarantees more usable hot water.
Thermal Insulation CFC/HCFC free fire retardant polyurethane foam with an ozone depletion potential of zero (ODP ZERO) and a global warming potential (GWP) of 1.
Casing Plastic coated corrosion proofed steel.
Capacities 90 120 150 180 210 250 300 litres
Pressure Testing To 12 bar
Safety Features
Indirect High limit thermal cut-out operates at 85°C wired in series with two port motorised valve.
Direct Manually re-settable cut-out on heating element. All models have a temperature and pressure relief valve factory set at 6 bar and 95°C.
Approvals All Stainless Lite Cylinders are manufactured in accordance with BS EN 12897 the specification for unvented water storage vessels.
The cylinders have been tested by KWA a member of the European Organisation for Technical Approvals (EOTA) and found to comply with building regulations G3 and water Regulation.
In performance, it complies with the requirements BS6700 and meets the NHBC criteria for domestic properties. Gledhill also operates a quality management system audited and accepted by the BSI in accordance with BS EN ISO 9001 :2000. |
