Bespoke plate heat exchangers in seven days

10 June, 2016

Suitable applications include generating heating and cooling water for large buildings such as colleges, hospitals, offices and sports facilities. These PHEs can be integrated with heating systems to either form a system pressure break, to protect a boiler from a dirty system or high pressure, or as part of district heating, solar, biomass, heat pump or heat dump systems.

To ensure that all products are fit for purpose, BSS has a dedicated in-house team of experts to provide technical support. Supplied complete with mounting feet and flange studs, the BOSS i-Series complements the existing range of BOSS products to form a range that will suit all HVAC applications and budgets.

Compact and light

Compact and light, the BOSS i-Series is a scalable and modular range that reduces installation and maintenance time to a minimum while providing the high thermal efficiency that modern day installations demand. Suitable for both oil cooling applications and water/water duties, the i-Series is designed to handle pressures of up to 10 bar and temperatures as high as 100degC.

The design has also reduced the overall dimensions and weight of each model; BSS claims this makes the BOSS i-Series up to 30 per cent lighter than comparable plate heat exchangers while also making them very compact. The height has been reduced by 10 to 15 per cent by making both the top and bottom bolts act as the carry/guide bar for the plate pack and the length is minimised by eliminating the support column and optimising the bolt length.

Employing the same ‘chocolate pattern’ design as in all BOSS plate heat exchangers, the i-Series delivers high thermal efficiency due to the even distribution of fluid over the plate width so there are no ‘dead-corners’ and the heat transfer area is fully utilised. The pattern also minimises maintenance because it reduces fouling tendencies by promoting turbulence so cleaning does not need to be carried out so often and there is less risk of local corrosion.

Many contact points

BSS reports that the plates themselves are strong and designed with many contact points. Each plate pack is supplied with low and high plates so it can be tailored to meet any requirements and each plate features a groove designed to provide maximum support to gaskets.

Clip-on nitrile gaskets make it fast and safe to replace any failing gaskets, which also keep fastening and sealing separate, so that should a clip break, the gasket still stays sealed. The ‘roof-top’ gasket design secures maximum sealing and perfect alignment thanks to an optimal profile with exact fit into the gasket groove.

The range consists of three models; the i100B and i100M which have a maximum HTA of 51 m2 and nominal thermal output of 150-7500 kW; the i60 and i60M, with a maximum HTA of 26 m2 and nominal thermal output of 80-2500 kW; and the i30, with a maximum HTA area of 1.6 m2 and nominal thermal output of 10-500 kW.All are backed by the BSS one-year warranty.
