The Helios unit heater with its futuristic polished aluminium and contoured design is rather special. This smart new concept in commercial heating units will accommodate all architects who are looking for something new and different. The Helios unit heaters are produced in 6 sizes from 5 to 60 kW and are available with a 1-row battery for steam and high temperature hot water installations, a 2-row battery for hot water installations and a 3-row battery for low temperature hot water installations. Thanks to its heart Sabiana is a leader in the sales of unit heaters in Europe. The battery of Sabiana Helios unit heaters with steel tubes 22 mm and aluminium fi ns has the following advantages compared with the copper-aluminium small diameter tube batteries. The material used for the steel tube, which is very thick (1 mm instead of 0,3 - 0,4 mm), makes the Sabiana battery extremely sturdy and long lasting. The tube big diameterreduces the water pressure drop: this means that reduced power pumps are installed and a very rapid heating capacity is provided. The Sabiana battery for unit heaters uses a reduced number of tubes to give the same yield: this determines a low resistance to the air fl ow and consequently an optimum leaving air temperature and a very high throw. The greater spacing between the fi ns as well as their thickness facilitate cleaning and maintenance operations, which is essential to keep the unit heater effi cient. The steel tube battery is the ideal choice for plants where all tubes and equipment are made of steel because it avaids physical and chemical unbalance due to the interaction of different metals. The special painting coat makes the battery long lasting and increasesthe thermal output. The Sabiana battery can be used with hot water and high temperature hot water with a wotking pressure up to 16 bar and with steam up to 10 bar. As a matter of fact each battery is submitted to two tests at 30 bars. However Sabiana in order to meet any design and installation need can offer a complete set of unit heaters with cooper tubes and aluminium fi ns. This battery has the same features (tube diameter, fi n pitch, atc.) of the steel battery but it is built with copper tube 0,7 mm thick, of higher quality and with a total weight which is double compared with the batteries normally used for unit heaters.The wide range of products includes 6 different sizes with 1, 2 or 3 rows each. > C > ASING Made from 4 angular diecast aluminium components and lateral elements made of extruded, anodized aluminium in a silver colour. 蕕 H > EAT EXCHANGER The heat exchanger is manufactured from the highest quality steel or copper tube. The fi ns are pressed from aluminium sheet, bonded onto the tubes facilitating the maximum transfer contact available. F > AN ASSEMBLY It is made up of three components: the fan, the motor and the fi nger proof guard, which also acts as the main support. Օ E > LECTRIC MOTOR The standard motor fi tted is a hermetically sealed motor which is maintenance free. The motor is supplied as standard for a three phase 230/400 V 50 Hz available in accordance to the size at 4, 6, 8 pole and at 4/8, 4/6, 6/8 two speed version. >
