Vahterus Plate & Shell Heat Exchangers
These have many benefits for refrigeration applications such as evaporators, condensers, cascade heat exchangers, desuperheaters and oil coolers.

PSHE’s are effective, durable and versatile due to their unique shell construction, together with fully welded plates. This makes PSHE’s ideal, having compact sizes and requiring low refrigerant charges.

Vahterus heat exchangers are suitable for all refrigerants, especially natural media such as ammonia and carbon dioxide.

Alfa Laval plate heat exchanger technology enables efficient evaporation with small temperature approaches. Alfa Laval designed the U-Turn separator to ensure efficiency and achieve smaller overall dimensions for easier and more compact installations.

The Case Story below explains how the UK’s Homerton University Hospital switched to a new ammonia-based cooling system  and increased cooling capacity by 50 percent. They also significantly reduced the refrigerant charge, and achieved a reduced environmental impact.

The Alfa Laval U-turn Separator brochure below details how utilising the best of Alfa Laval’s plate heat exchanger technology, the compact U-Turn solution delivers maximum separation efficiency and energy efficiency.

Alfa Laval plate heat exchanger technology enables efficient evaporation with small temperature approaches. Alfa Laval designed the U-Turn separator to ensure efficiency and achieve smaller overall dimensions for easier and more compact installations.

High quality plate-finned oil coolers with large extended surface resulting in a compact design giving low weight, small oil and water volumes with low pressure drops.
Available as either thermosyphon (1P) or liquid cooled (2P) design, with removable tube bundle for ease of maintenance.

Evaporators
The versatility of Vahterus PSHE’s is demonstrated particularly in evaporator applications. PHSE can be used as highly efficient flooded or direct expansion evaporators, due to low pressure drop and high heat transfer. Fully welded circular plates and a protective outer shell, guarantees safety for the end user. This construction also ensures high integrity and durability.
