Shell and coil heat exchangers operate by allowing one medium to flow through the coil while another flows through the shell, ensuring efficient heat transfer through the coil’s surface. The corrugated tubes enhance turbulence, maximising thermal exchange efficiency while minimising pressure losses. Their compact design allows them to be used in constrained spaces without sacrificing performance. In applications such as heating and cooling systems, the exchangers provide reliable performance with low maintenance requirements. The RAD variant is specifically designed to handle refrigerant flow, ensuring even distribution and optimal thermal performance for ground source heat pump systems.
