Keep Your Cooler. Add HALO.

Works with any brand cooler. HALO pairs with walk-in coolers, upright coolers, vault-style units, and freezers — whatever you already own. No need to replace equipment; just add monitoring.

Monitoring, not control. HALO watches your cooler around the clock — it records temperature, alerts you on excursions, and keeps the logs. It does not control or change your refrigeration settings, so it layers safely onto any existing system.
