Single-pass brazed plate heat exchanger SAFEPLATE LA14SP-10-3/4" (connections: 4 male threaded nozzles) 0201-0184

Safety and Efficiency in a Compact Housing

The SAFEPLATE LA14SP-10-3/4" brazed plate heat exchanger is designed for applications where reliability is a priority and installation space is limited. Its key distinguishing feature compared to standard solutions is a double-wall system combined with a special slot on the side surface of the housing. Thanks to this solution, in the event of damage to one of the layers, the fluids do not mix, and any potential leak is immediately visible from the outside. This is a crucial safety feature for installations where mixing of media could lead to serious failures or hazards.

The construction based on copper-brazed stainless steel plates ensures high corrosion resistance and mechanical strength. The brazing process in a vacuum furnace guarantees a permanent bond of the elements, resulting in tightness and resistance to cyclic temperature and pressure changes. This heat exchanger operates seamlessly at a maximum working pressure of up to 30 bar and a flow temperature reaching 230 °C, making it a universal component in various heating and technological circuits.

Applications and Operational Benefits

The optimal shaping of flow channels allows achieving a balance between low flow resistance and high heat exchange efficiency. Such selection of channel geometry also prevents the accumulation of contaminants inside the device, reducing the risk of blockages and extending the time between service inspections. Small dimensions (height 203 mm, width 81 mm) while maintaining high thermal power make this model ideal for modern domestic boiler rooms and compact industrial installations.

The device is equipped with four threaded connections (GZ) with a nominal diameter of 3/4 inch (20 mm) on both the primary and secondary sides. This solution facilitates installation and removal without the need for complicated adapters. It is worth noting that the heat exchanger's construction allows it to be covered with dedicated thermal insulation (available as an accessory), which minimizes heat losses and protects personnel from burns when working with hot media.

Key Construction Features and Operating Conditions

The heat exchanger is designed as a single-pass counterflow device, ensuring efficient heat exchange while maintaining construction simplicity. The stainless steel plates are permanently joined by copper brazing in a vacuum furnace, eliminating the need for mechanical gaskets susceptible to aging. The entire assembly is housed in a casing with a height of 203 mm and a width of 81 mm, allowing installation even in very tight technical spaces.

Operational safety is guaranteed by the double-wall system (SafePLATE), which not only prevents fluid mixing in the event of inner layer damage but also enables immediate visual detection of any potential leak thanks to a special inspection slot. The device is adapted for operation in demanding thermal and pressure conditions – it withstands temperatures up to 230 °C and a working pressure up to 30 bar. Hydraulic connections are realized via four external thread connections with a diameter of 3/4 inch (20 mm), simplifying integration with existing heating or technological installations without the need for additional reductions.

Thanks to the double-wall system, the device finds wide application not only in standard central heating (c.o.) and domestic hot water (c.w.u.) installations but also in systems requiring double protection against fluid mixing – e.g., in solar, refrigeration, or HVAC technological processes. Simple construction and the absence of mechanical gaskets eliminate the risk of their aging or leaks resulting from thermal expansion cycles. This is a solution for installers seeking durable components and for end-users valuing safety and low maintenance costs over years of operation.
