ultracal
A British standard 1566 ultra high performance double feed indirect system cylinder with Corrosion Resistant Technology. For
use in an open vented hot water system.
Primary Sytems
Ultracal is not suitable for gravity circulation.
Ultracal is suitable for pumped circulation only, and is capable of reheating from 10 to 60oC in 15 mins.
Ultracal is suitable for sealed primary systems operating at up to 3.5 bar. Primary coils with higher pressure ratings are available.
Reheat times assume that the primary flow is maintained at 82oC at a flow rate of approx 18 l/min.
Grade
available in 3 grades to suit the following working head.
Grade 3 |
10m |
Grade 2 |
15m |
Grade 1 |
25m |
Insulation
Ultracal has a single thickness of C.F.C free urethane foam lagging as standard, this adds approximately 50mm to the cylinder diameter.
Ultracal is available with a double thickness of C.F.C free urethane foam lagging on request, this gives lower heat loss, and will add approximately
100mm to the cylinder diameter.

Thermostat Boss
A 1/2" female thermostat boss can be factory fitted at no
extra charge if requested. This allows the use of an
insertion type thermostat which gives a quicker response
than strap on types. We can supply a Honeywell 6188B
insertion thermostat to customer order.
We recommend the use of an insertion type thermostat
when small capacity Ultracal's are heated by powerful
boilers. i.e. When a 60 or 80 litres Ultracal is heated
with boilers of 80,000 BTU or more.
