TECHNICAL AND CONSTRUCTIONAL CHARACTERISTICS, DIMENSIONS
4.1 Description of the appliance
The construction of the boilers in the PREXTHERM RSH N series guarantees high power and efficiency with low flue gas temperatures, thus
ensuring low polluting emissions. They are manufactured in accordance with standard EN 303, part 1. The main technical elements of the
design are:
- careful design of geometries to achieve an optimum ratio between combustion volumes and heat exchange surfaces.
- the choice of materials used, to ensure long boiler life.
The boilers feature pressurized combustion with 2 flue passes, a horizontal-cylinder configuration, and flame reversal in the furnace, completely
surrounded by the water that cools it. The flame produced by the burner is reversed peripherally toward the front, where the flue gas enters the
tube bundle, featuring turbulators to create a swirling path that increases the heat exchange by convection. On leaving the tube bundle, the flue
gas enters the rear chamber and is transferred to the chimney.
The boilers are fitted with a door featuring hinges that can be reversed for opening to the right or left, and is adjustable in both height and depth.
The body is insulated with a thick layer of glass wool, and covered with a further layer of tear pro of material. The external finish consists of
painted steel panels.
The boilers feature two 1/2" fittings for bulb sheaths (able to house 3 bulbs each). The pre-wired control panel (optional) is located above the
boiler, and allows for automatic operation.
