Multi-DENCOMany versions with top performance There are four cooling versions of the Multi-DENCO design available:A-Version, C-Version, X-Version and F-Version.A-Version. Using R410A with inverter compressors in the indoor unit, it can deliverthe best EER values with the security of a reliable refrigeration circuit.C-Version. Chilled water cooling utilising either four row or six row coils for highperformance along with a variety of valve and actuator combinations to suit anysystem requirements.The A-Version and C-Version can be made as CombiCool units: an additional chilledwater circuit added to the unit for primary cooling with the ability to suit FreeCoolingapplications and with the other circuit providing redundancy and backup.X-Version. To reduce sound or refrigerant within the controlled space, the X-Versionis similar to the A-Version except the compressors are located in the outdoor unit.F-Version. The combination of a mechanical and a FreeCool system createsopportunities for precision cooling with minimal energy requirements, whilstguaranteed resilience with the direct expansion circuit that is able to provide100 % of the cooling requirements.6

THE FLEXIBLEALLROUNDERMulti-DENCO is a flexible and adaptable product. Up to 130 kW inseven casing sizes, there are three cooling versions, two airflowdirections and several option strategies. It can work with roomcooling or aisle containment and can humidify, dehumidify and evenheat your room. With such a large variety of options, features anddesigns, it can be moulded to your needs.Inverter compressors. For direct expansion versions, inverter compressors allowthe unit to match your load. This enables closer, proportional control. The inverterlooks at several variables and then adjusts its speed to match the demand exactly.EC plug fans. The use of the largest EC plug fans possible for the space insidea Multi-DENCO unit allows for slower speeds resulting in quieter, more efficient fanoperation.Advance controls. The latest control technology is integrated into a Multi-DENCO unit along with a 4.3” touch screen display. This combines with networkingcapabilities and system recording to give high quality feedback and control.Inbuilt redundancy. All Multi-DENCO units can be customised into a CombiCoolconfiguration: Three rows of the coil being for one circuit, the other three being fora separate circuit. This allows for 100 % cooling redundancy within the unit withthe controls system being easily able to switch between each circuit.8
