RAC Pack Enclosed

Space at a Premium?

When Plant Room space is at a premium, the enclosed options facilitate external installation, protecting the equipment with a Marine Grade Aluminum enclosure that is easily removable for future service and maintenance.

The Trebles RAC Pack pump is controlled via a 0-10V signal from the air handling unit to ensure perfect synchronization and features built in dry run protection and an automated air purge function. The RAC Pump Package also includes a control box, pre-wired for 0-10V signal input, remote start/stop, pump alarm and a low pressure switch.

Once installed, a RAC unit can be left unattended for prolonged periods of time with minimal maintenance.
