Comprehensive Applications & Versatility

Brazed plate heat exchangers are widely utilized across modern refrigeration plants. They are primarily engineered to facilitate efficient heat transfer between a refrigerant (the primary fluid) and water or brine acting as the secondary fluid.

Our premium line of copper-brazed heat exchangers is primarily deployed in the following capacities:

• Evaporators: Optimized for dry expansion and efficient water cooling.

• Condensers: Designed for rejecting or recovering heat directly to water.

• Economizers: Excellent for cooling liquid refrigerant while simultaneously super-heating vapour refrigerant.

Additionally, our units can be effectively utilized as:

• Sub-coolers: To cool liquid refrigerants using well water.

• Intermediate Heat Exchangers: Applied in absorption cycles to preheat diluted solutions or pre-cool concentrated solutions.

How It Works

Brazed plate heat exchangers utilized for HVAC applications typically employ a parallel flow configuration to achieve the highest possible thermal transfer efficiency. Featuring a convenient single-pass design, all system connections are located on one side of the heat exchanger, ensuring streamlined and effortless installation.

Alternate Channel Pattern

When deployed as an evaporator, the intricate channels formed between the corrugated plates and corners are arranged so that the two media flow through alternate channels, consistently moving in opposite directions (counter-current flow). The two-phase refrigerant, consisting of both vapour and liquid, enters at the bottom left of the unit. The exact vapour quality depends directly on the operating conditions within your refrigeration plant.

Dry Expansion

The evaporation of the liquid phase takes place directly inside the channels. A specific degree of superheating is always required for this process, which is why it is formally referred to as “dry expansion.” The dark and light blue arrows clearly indicate the location of the refrigerant connections, while the water or brine to be cooled flows counter-currently in the opposite channel, with the dark and light red arrows highlighting the water/brine connection points.

Condenser Operation

When utilized as a condenser, the core structural components remain identical to those of the evaporator. The refrigerant enters the unit at the top left as a hot gas and immediately begins to condense across the surface of the channels. Once fully condensed, it undergoes a slight subcooling phase—a process known as “free condensation.” The dark and light blue arrows designate the brine connection locations, while the refrigerant flows counter-currently in the opposite channel to be efficiently cooled (indicated by the dark and light red arrows).
