The heaters shown are for fitting to a storage tank where a suitable connection exists. A similar unit, without a flange, can be provided to Weld In to the tank, if desired. General uses include : Small storage tanks for oil (or water to special Order) Low cost installations

All units have a Watts Rating appropriate to the fluid type used , which is between 5 and 8 W/sq.in. ( 0.77 and 1.2 W/sq.cm.) for oil. All units sized using 3.4 bar(g) steam Heaters can use a Steam Pressure of 14 bar(g) Maximum

Ratings based on Oil StorageTemperature of 40 C and an Oil Outlet Temperature of 55 C

Standard Equipment : Removable Core type Heating Elements Controlling and Safety Thermostats as appropriate Thermometer Oil Outlet & Oil Return connections to suit Weathertight Terminal Cover arrangement Cable entries to suit

The outputs shown are the best values obtainable for the particular heater at the stated temperature rise. Other temperature rises may be calculated on a pro-rata basis, i.e.

600 litres/hr @ 6kW load = 15 C rise, so 300 litres/hr @ 6 kW load = 30 C rise

Formula : kW = litres/hr x temp rise (C) / 1464

Extra Items are : Spirax Sarco Steam Regulator & Control Valve Steam Trap set, sight glasses etc. Multiple stage design, extra thermostat, wiring etc. Change of flange specification to non-standard Delivery UK - usually a nominal charge only.
