Kettle Type Evaporator

The Vahterus Combined Evaporator is a heat exchanger where the droplet separation system is integrated with a flooded evaporator, making it a particularly efficient and compact system. The product has been developed to reduce the dimensions of a traditional evaporator and separator system. Furthermore, it is designed to minimise the refrigerant charge.

The Combined solution integrates the evaporator and separation system within a single vessel, which makes installation easier. Its compact design enables easy integration into packages and provides additional benefits such as savings on insulation and associated piping. Vahterus PSHE Combined is often the best solution when space is very limited.

Vahterus has also developed a second-generation combined evaporator, Combined C, for even more compact refrigeration packages. The model has an ammonia suction connection on the end plate of the shell. The connection size will be matched to the shell size of the unit. Another innovation is the location of the ammonia injection close to the outer shell. The top of the shell is designed so that it will remain free from any connections. This will enable the positioning of other components such as a condenser on top of the evaporator, with only a small space for insulation required between the units.

The Combined C is a very safe solution for ammonia with low charge.
