OSO Maxi Turbo 17R(S)

The Maxi Turbo calorifiers are manufactured from stainless steel up to 1,000 litres or copper lined steel when up to 5,000 litres. The Turbo is highly efficient and suitable for large hot water requirements, utilizing an external plate heat exchanger dimensioned to particular demands. All units manufactured to the international standard ISO/DIS 2694 (BS 5500). Maxi Turbo units can also be manufactured to individual specification.

Cold water is pumped from the bottom of the cylinder through a plate heat exchanger and pressure reduction valve, which is regulated at start-up until the thermometer shows 80°C. The cylinder is charged from the top. When there is little consumption, all domestic hot water is produced directly through the plate heat exchanger. When consumption is high, the cylinder supplies the necessary amount of hot water. Double pumps and safety are fully integrated in the installation kits.

The external heat exchanger, pump sets, cold water inlet set and mixing valve are delivered separately, with dimensions depending on the required flow rate. The installation kits are fitted directly on the cylinders’ front, along with the mandatory safety valve and Pressure & Temperature Relief valve.

All calorifiers are fully insulated within a protective steel casing. Expansion of secondary water can be accommodated either internally in a self-initiating air gap or externally in dedicated expansion vessels. Vented format is also available for connection to gravity feed from storage tank.

Key advantages:

• Stainless steel pressure vessel for working pressures up to 10 bars.
• Plate heat exchanger, pump sets, cold water inlet set and mixing valve fitted in front.
• Highly efficient and space-saving.
