Manufacture of Rayka Packman condensing hot water boiler

The construction of Rayka Packman condensing boilers is carried out in accordance with ASME standards

Additionally, all parts related to the pressure components comply with comprehensive ASME codes.

Furthermore, all materials used in the heat exchanger are selected according to ASTM requirements.

Materials of the Rayka Packman condensing hot water boiler

The construction of Rayka condensing boilers is carried out using tubes from the 300 series of stainless steel (Austenitic Stainless Steel 3xx Series) Due to the presence of nickel and chromium, it is a material resistant to the operating conditions of the boiler. Stainless Steel 316L alloy is the most resistant alloy to acidic corrosion This acid is generated from the operation of the condensing boiler.

The main reason for the high efficiency of this boiler is the condensation created within the boiler. One of the few alloys resistant to this condensation at high temperatures is 316L Stainless Steel. Due to the presence of nickel and chromium, the material is resistant to the operating conditions of the boiler.

The efficiency of Rayka Packman condensing boilers is based on a high-efficiency combustion system, reaching up to approximately 98.9% in HHV (depending on the relative humidity of the ambient air). This is according to Chapter 32 of the ASHRAE-HVAC System & Equipment Handbook, 2012 edition, which represents the highest level of efficiency for condensing boilers.

These boilers are designed with a lower water volume compared to three-pass firetube hot water boilers, which categorizes them as Low Mass boilers, similar to other condensing boilers manufactured worldwide. This boiler can operate within the appropriate range for building design in terms of the temperature differential between supply and return, which may require the use of primary-secondary loop for system balance.
