These devices provide total control of your Unit and fast, easy air filter replacement with no tools.

To simplify installation, Smart Grilles™ feature fully tested harnesses.  These harnesses carry signal, control and communication circuits along with pressure reference tubes between the Grille and Unit.

The harness cable connectors and tubes plug into an interface module located just inside the Unit’s return opening. This easy installation process makes your Unit fully functional! As a result, the only wiring required during installation is power to your Unit and optional connections to unit fault alarm or emergency unit shutdown circuits!

At Bebco we offer more than a makeshift bracket clipped to your return grille, so your controls are not moved to change filters or mounted in the path of dusty return air! 

Think Smart Snouts™ when outdoor access to your unit is restricted or difficult…

SMART SNOUTS™
As an optional feature of our Custom Series Units, Bebco Smart Snouts™ require a single cutout to provide full access the unit controls along with fully installed discharge and return grilles.

Integrated Pressurization,  Ventilation or Make-Up Air Systems

– Satisfies NFPA 496, API RP-500 & IAQ Requirements

NFPA 496 Compliant Pressurization Systems
Bebco Integrated Room Pressurization Systems are available with our Express and Custom Series Units and provide an interlock to prevent the Unit refrigeration system equipment from energizing until safe room conditions are achieved. Blower speed is perfectly regulated by a variable speed drive when doors are closed to maintain safe room pressure and ramps up slowly to maintain required air flow velocities through doors during egress. As your door closes and room pressure rises, the drive then quickly reduces blower speed to prevent the annoying and sometimes painful sensation of sudden room pressure increases.

API 500 Compliant Ventilation Systems
Bebco Integrated Room Ventilation Systems are available with our Express and Custom Series Units and maintain a constant air flow at exchange rates that are fully adjustable to meet your AHJ’s requirements. As a significant benefit of these integrated solutions, fresh outside air is first conditioned by your Unit before entering your room or building.

These units also provide an essential emergency override to quickly remove any traces of hazardous substance from a room or building.  The override can be activated by a combination of gas detectors, local panic buttons and remote control locations.

Make-Up Air Systems
Bebco Integrated Room Make-Up Air Systems are available with our Express and Custom Series Units and consists of two opposing blade dampers in material to match your case material selection, to maintain a constant air flow at exchange rates that are fully adjustable to meet your AHJ’s requirements. As a significant benefit of this integrated solutions, fresh outside air is first conditioned by your Unit before entering your room or building.

Adjustment is fully detailed in our Installation, Operation and Maintenance Manuals, so that the perfect balance of returned air and fresh outside air can be achieved !

As one of our most important features, we provide low ambient control for all Wall Mount Units. This control feature is provided to maximize performance and efficiency during intermittent or sustained periods of cold outdoor temperatures. By experience, we know that outdoor temperatures can fall rapidly and unexpectedly in any climate, despite the fact that our wall mount units are often required to offset significant heat loads inside your buildings at all times. By monitoring refrigerant head pressure with switches or transducers, our Low Ambient Controls permit the Unit to operate in a continuous and highly effective manner year-round, regardless of significant outdoor temperature fluctuations!

DEFROST CONTROLS – Provided with all Model WHP Heat Pump Units!

As another beneficial feature, all Bebco Model WHP Wall Mount Heat Pump Units are provided with defrost control to prevent icing or frost during cold outdoor temperature conditions.
