1 Steel Shell Boiler Responsibility for energy and environment Output range 144 to 4150 kw

2 Why choose? The Hoval is a well proven steel shell boiler designed and manufactured in Britain under EN ISO 9001 being fully CE-marked. The offers both high efficiency with low NOx and is based on the proven reverse flame pattern of firing. Our wide range of boilers will suit almost any customer s space heating requirements. Economical Ecological Saving energy Low impact on the environment Cost-efficient solution due to low investment cost Best effectiveness due to patented dimpled tubes on the gas side Power saving and high efficiency due to large water capacity Environment friendly due to low NOx emissions Low CO 2 emissions due to minimal fuel consumption Outstanding emissions values due to modulation of low NOx burners Easy to use Simple maintenance Versatile operation Sophisticated Easy to use due to intelligent design details User friendly controls with TopTronic control available Service friendly due to easy front door access Large range of applications due to flexible combination options Space-saving due to compact design Simple installation due to high flexibility in positioning 2

3 The complete range extends from 144kW to 4150kW. At Hoval we have the perfect system for almost any requirement. Highly efficient, low NOx heating for commercial and industrial applications. 3

4 Highly efficient, conventional steel shell boiler Clean combustion The boilers are of mild steel welded construction in which the outer shell forms a water space around the combustion chamber. The final pass water jacketed gas passage ways with dimpled tubes provide an effective secondary heating surface. With the proven three-pass technique, the hot combustion gases are immediately moved out of the high-temperature zone. The flame temperature is reduced, and the pollutant emissions are minimised. Low operating costs The transforms the energy stored in oil and gas into valuable heat with impressive energy - this is demonstrated in a net efficiency to 91.6%. You will benefit from this high efficiency in the form of substantially lower heating costs. The excellent insulation of the boiler lowers the stand-by losses to less than 0.4% and further reduces the energy consumption of the system. Intelligent command centre for your heating system All boilers are supplied with an integral standard control panel which is top or side mounted for models 175 to 900 and side mounted as standard for models 1200 to As an optional extra the TopTronic control system is available which allows the easy control of up to five cascaded boilers. Burners The is suitable for operation with a range of matched burners for use with oil, gas or dual fuel. It is Hoval policy to supply boilers with matched burners from several recognised manufacturers. Details of gas pressures, noise levels, acoustic shrouds etc. are given on individual quotations. User-friendly operation Flue gasses pass to a rear mounted flue outlet box and horizontal flue outlet. The flue outlet has a spigot/ flange for connecting to the installers flue pipe, and is fitted with a door for cleaning and access. Application however you want it The boilers are intended for heating commercial and industrial premises. They may also be used to supply domestic hot water to premises in conjunction with an indirect calorifier. The boilers are suitable for working pressures up to 6 bar and operating temperatures to a maximum of 100 C. On special request boilers are available for operation up to 132 C with 4.5 bar operating pressure. 4
