Helo, We are doing a prototype and is in need of a Small Tonnage indirect Fired Absorption Chillers (Ammonia or LiBr based- with no compressor). A 5T capacity would be ideal. If the system can be designed in a way that when the hot medium (hot water) is not available, it could work on gas fired heating, it would be ideal. For the prototype we will need one unit and once testing complete, we will be placing bulk orders of 50 to 100 units. Please can you send me a product sample? Show More
