Surveillant Controller

Customer reviews

Surveillant is an energy saving refrigeration controller for walk-in freezers or coolers, with remote monitoring and diagnostics. It’s the first product to perform true demand defrosts utilizing real-time measurements of the system’s performance to determine when to initiate defrost. Surveillant maximizes energy efficiency while minimizing the effects of defrost on the space temperature resulting in energy savings, constant product temperature, and reduced product shrinkage.
