INTRODUCTION

Portrait of a market leaderin a steady growth

IMMERGAS: NOw AvAILABLE IN 30 COUNTRIESImmergas presence on the international market has been increasing year after year. Today the brand is available in more than 30 countries; the company structure includes 9 branches in Europe and one in China, as well as shares in significant import firms all around the world.Immergas is deeply investing in promotion and communication, with the aim of supporting the brand and penetrating new markets. From Asia to South America the company is steadily expanding, with a policy based on quality, vanguard products and accurate service.

Immergas is the leading company in the Italian market of gas heating boilers. In the headquarters of Brescello work more than 700 people, spread over an area of 50,000 sq.m.In 2008 Immergas sold more than 300.000 appliances; the turnover was 240 million euro, more than 55% of which on the international market.The range of products is continuously widening, in order to satisfy all marketrequests. At the moment Immergas offers more than 70 models, wall-mounted or floor standing, instantaneous, for outdoor installation, condensing, with sealed chamber.An extremely wide choice with a common characteristic: the research for reliability, long-life, convenience.

INTRODUCTION

LOw EMISSIONS ANDECO-fRIENDLy PRODUCTS: PLANET EARTH SAyS THANkSImmergas pays great attention to nature and environment. Our Research and Development Department is more and more eco-oriented: this investment in terms of staff and resources is our contribution to make the world a cleaner space.When projecting new models, the search for energy saving is always the main issue, in order to reduce energy consumption and pollutant emissions. In Italy, Immergas is leader in the segment of condensing boilers, which offer up to 30% energy saving as compared to traditional ones.

CONDENSE AND ENjOyA condensing boiler is an eco-friendly boiler. The special burner allows to lower pollutant emissions such as carbon monoxide (CO) and nitrogen oxides (NOx), two of the main responsible of air pollution. In fact, condensing boilers belong to class 5, the most environment-friendly class established by the European standards (UNI EN 297 e UNI EN 483).Condensing boilers have an advanced modulating system which can perfectly adjust the heat output to the real needs of the heating system. The modulating range, wider than in traditional boilers, ensures the right comfort and wellness inside the house, in all different climatic situations throughout the year.

POwER: fROM 10 UP TO 920 kw!Light commercial VICTRIX range is composed by wall-hung condensing boilers with heat outputs from 50 to 115 kW, designed by Immergas to satisfy different kinds of installation exigencies.The high efficiency ratings achieved are ideal when it comes to heating large volumes domestic systems (such as semi-detached houses or apartment blocks) and for commercial and industrial uses.Light commercial VICTRIX models are heating only appliances, pre-engineered to operate both as single appliances or in cascade, with the advantage of providing a globally higher efficiency at lower running costs.The wide modulation range characterizing the light commercial VICTRIX models and the possibility to manage up to a maximum of 8 appliances in cascade, allow to obtain great flexibility in the offer of the available heat outputs.

THE CASCADE SySTEMThe cascade system consists in the installation of two or more modular generators in parallel, connected to a control system regulating its functioning as if it was a single appliance.The total heat output is equal to the sum of each single generator output.Distributing the heat output on more than one unit brings many important advantages:

Higher efficiency compared with the use of a single generator of great heat output, which would have to work with a reduced heating load for a good part of the heating period, with consequent general lower efficiency.

Less expenses thanks to the better efficiency.

Greater safety as the subdivision in more units allows to maintain the heating function active even in case of maintenance on one of the connected appliances.

Greater flexibility with the possibility of distributing the heating request on all the appliances, while the functioning sequence avoids the fast deterioration of one boiler respect the other.

INTRODUCTION

Cascade and zones regulator Zone manager Modulating room thermostat

CASCADE AND zONES REGULATORCentral unit of the thermoregulation system, it allows to control, monitor and program the operating sequence of a maximum of 8 generators in cascade. The regulator controls the boiler’s delivery temperature adjusting it to the system requirements.The regulator can manage up to 3 different zones (2 of which at high/low temperature) and a sanitary circuit for a separate storage tank. It is also possible to install up to 5 regulators in parallel (of which only one, called master, will be connected to the generators) to control up to a maximum of 15 heating zones and 5 storage tanks for the domestic hot water production.

.03

THE THERMOREGULATION SySTEMAll light commercial VICTRIX boilers are provided with new generation electronics, offering the best performances thanks to their regulation flexibility. In case of zones systems or cascade systems, it will be necessary to pre-arrange an adequate thermoregulation device able to manage every single appliance and elaborate the information from the system, in order to meet the most varied operating requirements.

.04 .05

zONE MANAGERConnected to the cascade and zones regulator, it allows to keep the operating appliance and the heating system information handy and under control. This means that the previously set functioning parameters (turn on/off, temperatures, etc.) can be easily modified by the user, without having to operate on the central regulator.

.04

ExTERNAL PROBEConnected to the boiler, it allows to optimize the energy consumptions automatically adjusting the system delivery temperature to suit the outdoor temperature variations.

SySTEM DELIvERy PROBEIt allows the cascade and zones regulator to manage the system temperature.

SEPARATE STORAGE TANk PROBEIt allows the cascade and zones regulator to control the temperature of a separate storage tank.

.05 MODULATING ROOM THERMOSTATConnected to the cascade and zones regulator, it allows the user to regulate the room temperature of the single zones into which the system is divided.

SINGLE INSTALLATIONAll light commercial VICTRIX models are standard provided in B23 configuration (open chamber, fan assisted) but they can work also as sealed chamber fan assisted (C type) using the special kits supplied by Immergas. To correctly install the boiler, it is necessary to use the original

Immergas “Green Series” flue systems; these components and accessories are specially designed to guarantee higher resistance to corrosion and fast and easy installation, thanks also to the push-fit assembly and special gasket seals.

CASCADE INSTALLATIONIn case of cascade systems in B23 configuration (open chamber, fan assisted), it is necessary to use a special flue manifold with a non-return device (flue locks) supplied by

Immergas, so that the combustion products of one working boiler do not interfere with the combustion circuit of the not working boilers.
