INTRODUCTION<\/p>\n<\/div><\/div><\/div>

<\/div>

Designed to meet the needs of industrial processes<\/h2>\n<\/div><\/div>
<\/div>

Our goal is to add technological value to industrial refrigeration projects by simplifying installation and improving process reliability, safety and efficiency.<\/h3>\n<\/div><\/div><\/div><\/div>
<\/div><\/div><\/div>
<\/div>
<\/div><\/div>

The RFU ammonia-based chillers are designed with a compact format to optimise the space and reduce the ammonia charge, making them the best solution where space is limited, and where there are restrictions on the refrigerant charge used.<\/p>\n<\/div><\/div><\/div><\/div>

RFU chillers are designed with 2 or 3 compressors and drivers with VSD to offer the most
\ncost-effective solution in the market to deal with changing circumstances and different operating requirements.<\/p>\n<\/div><\/div><\/div><\/div>

<\/div>

General characteristics<\/h2>\n<\/div><\/div><\/div><\/div><\/div>
<\/div>

01.<\/sup><\/p>\n<\/div><\/div>

Condensation<\/h4>\n<\/div><\/div><\/div>

Ammonia condensation can be done by using a remote condenser (air, evaporative, adiabatic) or by integrating an exchanger in the chiller itself to condense ammonia with water.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

02.<\/sup><\/p>\n<\/div><\/div>

Integral control system<\/h4>\n<\/div><\/div><\/div>

CIntegral control system with a Siemens S7-1200 PLC with PROFINET communication, Schneider Electric 10\u201d screen and inverters for com-pressor control. Remote access available.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

03.<\/sup><\/p>\n<\/div><\/div>

Outdoor installation<\/h4>\n<\/div><\/div><\/div>

We offer the possibility of designing and manufacturing the equip-ment with an external housing, protecting all the elements against the weather.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

04.<\/sup><\/p>\n<\/div><\/div>

Pumping skids<\/h4>\n<\/div><\/div><\/div>

Possibility of integrating pumping groups for the transmission of cold liquid from the evaporator or hot liquid from the heat recovery PHE.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div>

<\/div>

05.<\/sup><\/p>\n<\/div><\/div>

Flexibility<\/h4>\n<\/div><\/div><\/div>

The flexibility to adapt our solutions to the specific needs of the project to offer the best solution.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
