Brazed Plate Heat Exchangers

APV ParaBrazed is a large range of compact brazed plate heat exchangers specially designed for a multitude of heating and cooling applications with high temperature and/or pressure.

APV ParaBrazed is characterized by: :

• Compact design with minimum space requirement
• High heat transfer efficiency
• Flexible in use
• Working temperature 195°C/-50°C
• Working pressure up to 30 bar

Working principle

APV ParaBrazed is a simple construction consisting of corrugated metal plates stacked on top of each other. The front and rear cover plate on which connections are located covers the plate pack. The plate pack, cover plates and connections are copper brazed to obtain a compact and highly durable plate heat exchanger. High thermal efficiency is obtained by letting the two media in parallel flows run in countercurrent flow through alternate channels.

Application:

APV ParaBrazed is specially designed for heating and cooling of liquids in industrial, HVAC and refrigeration applications.
Typical HVAC applications include heating of domestic water and central heating water – radiators as well as floor heating – primary heating sources being e.g. district heating, solar heating, and heat pumps. In refrigeration APV ParaBrazed is often used for evaporation and condensations duties with freon-like liquids as primary source. Other applications include oil coolers and oil heaters.
Note: Ammonia and seawater must not be used as media in

Benefits:

The APV ParaBrazed heat exchangers are easy to mount and install, and their compact design requires minimum space.
Due to the large temperature span and high working pressure APV ParaBrazed offers high flexibility in use. Its high thermal efficiency reduces the consumption of the heating media to a minimum making the ParaBrazed range of plate heat exchangers an efficient and cost-effective choice.
