APC ACRMD4KT-2 3.5 kW Split System Outdoor Unit | HVAC Controls

Keep critical equipment within its thermal envelope with an outdoor unit built for split-system cooling. This APC 3.5 kW model is pre-charged with refrigerant, reducing installation steps and helping teams move from delivery to commissioning with less handling at the job site. For edge rooms, telecom spaces, and compact IT environments, cooling capacity has to be matched to the load without adding unnecessary complexity. The outdoor unit format supports a split-system architecture that separates heat rejection from the conditioned space, which is often the right choice when floor space is tight and service access matters. Pre-charged refrigerant adds practical value by simplifying the install path and reducing the chance of field charging errors. This is the kind of component selected when uptime, thermal stability, and deployment discipline matter more than lowest-cost hardware. It fits projects where the cooling system is part of the infrastructure plan, not an afterthought.
