Industrial Hot Water Boiler for Oil or Gasfiring Description Industrial Hot Water Boiler The Hoval high output hot water boilers are made of high quality steel and are distinguished by their solid, robust and elastic construction.they particularly convinve by their easy way of operation, their easy maintenance and an optimal efficiency. The client receives an economical, environment friendly compact unit, ready for installation. The boilers are constructed for oil- or gasfiring. The construction and manufacturing of the boilers is done according to TRD. The local oficial approval and inspection is carried out by TÜV or an independent test authority. The ISO 9001 certification and the quality approval at our factory with our Hoval quality performance departement with works certificate guarantee the highest product quality. Type The type classical 3 pass flame tube flue gas tube boiler with an inner completely water cooled flue gas turning chamber guarantees high efficiency. The boiler consists of a cylindric shell, the two headplates, the centric flametube including the back flue gas turning chamber with water cooled finned tube wall and the two flue gas passes. The boiler door is thermal insulated and flue gas tight for burner mounting. The boiler is completely electrically welded and provided with all required inspection openings. The spacious designed flame tube with low thermal charges results in an exellent combustion and reduces emissions. The large water content secures an even boiler running time and thus reduces the number of boiler starts. Admissible working pressure / temperature Standard pressures: 6 and 10 bars. Higher pressure on request. Max. temperature: 110 C (depending on local regulations). Thermal Insulation The boiler is fully insulated including flue gas collector with 100 mm rock wool insulation. The casing is made of structured aluminum plate, thickness 1mm. Sockets and cuttings are nicely framed. High Efficiency Due to the above technical facts an efficiency of min. 92,5% can be achieved. Thus continuos fuel costs are kept low. The sources of energy are used more efficiently and Hoval spares the environment. Control Panel The electro control panel for the Hoval boiler is equipped with the required control units and indicators for control and supervision of boiler and burner. The operation and alarm reports are shown as fault indication. The control panel will be made upon customer requirements and depending on burner to be used. A description of the control panel display SLC 28-1 can be found on page xyz of this catalogue. Feed Water Quality Local feed- and boilerwater regulations have to be followed and waste water regulations have to be payed attention to. Total hardness less than 1 f, ph-value 8.3-9.5 and for installations with parts made of aluminum or non ferrous metal 8.3 - max. 9, Oxygen < 0.1 mg/l. Delivery The pressure body is completely insulated with a primer. The insulation is fixed at the factory and connection openings are rain covered. Burner armatures and control panel are choosable either mounted on the boiler or packed loosely in a separate box. Assembling of boiler and wiring can be done at site by a local contractor resp. customer. On Request - Volt free contacts for BMS connection (Building Managment System).

THW-IZ Industrial Super-Heated Hot Water Boiler THW-IZ for Oil- and Gasfiring Description THW-IZ Industrial Super-Heated Hot Water Boiler The Hoval high output super-heated hot water boilers are made of high quality steel and are distinguished by their solid, robust and elastic construction. They particularly convinve by their easy way of operation, their easy maintenance and an optimal efficiency. The client receives an economical, environment friendly compact unit, ready for installation. The boilers are constructed for oil- or gasfiring. The construction and manufacturing of the boilers is done according to TRD. The local oficial approval and inspection is carried out by TÜV or an independent test authority. The ISO 9001 certification and the quality approval at our factory with our Hoval quality performance departement with works certificate guarantee the highest product quality. Type THW-IZ The type THW-IZ classical 3 pass flame tube flue gas tube boiler with two flame tubes with an inner completely water cooled flue gas turning chamber with tube wall guarantees high efficiency. The boiler consists of a cylindric shell, the two headplates, the two flametubes including back flue gas turning chamber with water cooled tube wall and the two separate smoke gas passes. The boiler door is warmth insulated and and flue gas tight for burner mounting. The boiler is completely electrically welded and provided with all required inspection openings. The spacious flame tube with low thermal charges results in an exellent combustion and reduces emissions. The large water content secures an even boiler running time and thus reduces the number of boiler starts. Admissible working pressure / temperature Standard pressures: 10, 13 and 16 bars. Higher working pressure on request. Max. temperature: up to 210 C Thermal Insulation The boiler is fully insulated including flue gas collector with 100 mm rock wool insulation. The casing is made of structured aluminum plate, thickness 1mm. Sockets and cuttings are nicely framed. High Efficiency Due to the above technical facts an efficiency of min. 90%, 95% with Economicer, can be achieved. Thus continuos fuel costs are kept low. The sources of energy are used more efficiently and Hoval spares the environment. Control Panel The electro control panel for the Hoval boiler is equipped with the required control units and indicators for control and supervision of boiler and burner. The operation and alarm reports are shown as fault indication. The control panel will be made upon customer requirements and depending on burner to be used. A description of the control panel display SLC 28-1 can be found on page xyz of this catalogue. Feed Water quality Local feed- and boilerwater regulations have to be followed and waste water regulations have to be payed attention to. Total hardness less than 1 f, ph-value 8.3-9.5 and for installations with parts made of aluminum or non ferrous metal 8.3 - max. 9, Oxygen < 0.1 mg/l. Delivery The pressure body is completely insulated with a primer. The insulation is fixed at the factory according to the size of the boiler body and as far as transport technically possible. Connection openings are rain covered. Burner armatures and control panel are choosable either mounted on the burner or packed loosely in a separate box. Assembling of boiler and wiring can be done at site by a local contractor resp. customer. On Request - Volt free contacts for BMS connection (Building Managment System).
