Optimized for high efficiency
The modular packaged cooling unit is optimized to work in conjunction with highly efficient make-up air delivery methods, such as perimeter supply plenums. The unit can either have a down or end discharge, and can be used with both electric and gas heat. All refrigerant is environmentally friendly R-410A and condensers have a nominal SEER rating of 14 for greater efficiency.
One benefit of this unit is the multiple cooling stages. Multiple cooling stages increase the efficiency by not using 100% of the cooling capacity when this is not needed, thus allowing lower energy usage. An internal make-up air cooling thermostat automatically energizes the first stage when cooling of the make-up air is required. The same thermostat has a built in adjustable differential to energize the second stage of cooling when required.
The condensers are top mounted on the make-up air unit to minimize roof space requirements, and are situated for optimal airflow and serviceability.
