All about the natural refrigerant ammonia (NH3) in cooling & refrigeration: News, Products, Jobs, Events, Knowledge, Forum, B2B Networking.

A leading supplier of refrigeration and air conditioning products, LU-VE is also very active in the field of natural refrigerants, including ammonia. As a new ammonia21.com bronze partner, the Italian company will showcase its new generation of ammonia heat exchangers that ensure a very high ratio of capacity to cost.

Specialised in heat exchangers for refrigeration, air conditioning and industrial applications, LU-VE has become an expert for industrial unit coolers for ammonia operations, including the following ranges:

• LSA-CSA industrial unit coolers for ammonia
• HDIA dual discharge for ammonia

New generation of ammonia unit coolers

LU-VE has developed a new generation of ammonia unit coolers that is using a tube with significantly reduced diameter. In a case study the company compared two new units in the LSA series incorporating the reduced diameter tube to two traditional products used in the ammonia refrigeration sector. The first uses a traditional exchanger in galvanised iron, the other one uses stainless steel tubes and aluminium fins of geometry 50 x 50. The results of the tests revealed main advantages, including: i) greater capacity at equal surface area, ii) significant internal volume reduction at equal capacity and surface. The latter represents a real advantage in terms of ammonia charge in the evaporator, especially compared to the galvanised iron technology, with a volume reduction of 3 times. Even compared to the product with stainless steel tubes the reduction is around 35%. In addition, manoeuvring and installation are greatly simplified thanks to the much reduced weight of the units compared to galvanised iron products.
