The Vanguard L boilers are a range of steel shell pressure jet
boilers offering high efficiency operation, ease of maintenance,
fuel flexibility and low emissions.
Suitable for oil or gas operation the Vanguard L range is supplied
in a choice of 18 standard models, rated in outputs from 130kW
(443,000 Btu/h) to 3500 kW (11,942,000 Btu/h). The range has a
maximum operation pressure of 6 bar.
Designed with a large combustion chamber that is positioned
in the lower part of the heat exchanger, the Vanguard L range
ensures maximum heat transfer efficiency (up to 92.5% net).
Through the use of an increased number of flue ways tubes
which are positioned in the hottest area of the heat exchanger
and constructed from a thicker steel construction than that
of traditional boilers, the Vanguard L range is capable of an
impressive output to size ratio.
