From Declassified to
Class I, Division 1 Area Ratings

Pay only for what you need, while maintaining complete compliance with all safety requirements…

Our Most Popular Configurations:

APPLICATIONS:
Rooms or Buildings in passive to highly corrosive environments, with no Hazardous (Classified) Substances in the surrounding atmosphere, or Rooms or Buildings that are declassified by separate or integrated NFPA 496 Pressurization or API 500 Ventilation equipment, with no internal source of hazard substances; or rooms or buildings that are established by the AHJ as suitable for ordinary location equipment that are located in a Hazardous (Classified) Area, up to Class I, Division 2, Group A-D.

These Controls are also ideal for Rooms or Buildings located adjacent to Division 2 Areas, to enhance facility safety.

UNIT FAULT & ROOM TEMPERATURE ALARM CONTACTS

• Indicates unit fault due to high or low refrigerant pressures
• Also indicates excessively high and low room temperatures
• Select from normally open or normally closed contact settings
• Contacts rated for up to 240 VAC at 10 Amps, maximum

EMERGENCY SHUTDOWN CIRCUIT

• Provides a means to deactivate your unit remotely
• Requires a dry closed contact to maintain unit operation
• 24 VDC milliamp voltage sensing circuit requires no shielding

As an optional feature, Bebco offers all Model WAC Air Conditioner and WHP Heat Pump Unit Controls with Room Temperature Setpoint Lockouts to prevent unauthorized adjustment or tampering.

The lockout mechanisms for our Digital and Touch Screen Thermostats may be activated or deactivated at any time by authorized personnel with the knowledge to use them.

The lockout mechanisms for Smart Cool™ and Smart Pump™ Controls are embedded in the Digital Touch Screen Controller programs, and may be discreetly activated or deactivated at any time by authorized personnel with knowledge to use them.

This feature is intended to prevent unwarranted or unauthorized tampering and for special applications that demand precise room temperature control. As one example, a lockout may be essential for an analyzer building to maintain a specific temperature range that ensures proper analyzer operation and output data accuracy.

SMART GRILLES™
As an exclusive and optional feature of our Express and Custom Series Units, Bebco Smart Grilles™ provide an integrated control system that mounts easily and is connected to your unit in minutes, featuring your choice of control interface devices. This Grille mounted devices provide total control of your Unit and fast, easy air filter replacement with no tools.

To simplify installation, Smart Grilles™ feature pre-connected and fully tested wire and tube harnesses with quick-connectors. The harness then plugs into an interface module located just inside the Unit’s return opening. This easy installation process makes your Unit fully functional! Therefore, 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 a flimsy grille, so your controls are properly secured and not mounted in the path of dusty return air!

SMART SNOUTS™
As an optional feature of our Custom Series Units, Bebco Smart Snouts™ require only one large wall cutout and combine the air discharge, air return and unit controls in a single and highly ergonomic manner.

Our Smart Snouts™ provide complete and easy access to all electrical control components inside your room or building, along with fast and easy air filter replacement. They can also be custom-sized to fit existing wall cutouts, allowing you to quickly replace similar products that were originally provided by other manufacturers.

Best of all, just like our Smart Grilles™, the only wiring required during installation is power to your Unit and optional connections to unit fault alarm or emergency unit shutdown circuits!

ORDINARY LOCATION HEATING ELEMENTS – for GG and G2 Configuration Units
These conventional wire-coiled heating elements are an optional Express or Custom Series Unit feature for applications where the interior space of your room or buildings is declassified by NFPA 496 pressurization, API 500 ventilation or by the Authority Having Jurisdiction (AHJ).

HAZARDOUS LOCATION HEATING ELEMENTS – for 22 Configuration Units
These advanced fin-tube elements are an optional Express or Custom Series Unit feature for applications where the interior space of your room or buildings is not pressurized, not ventilated or considered as hazardous by the AHJ. To maintain applicable T-Code temperature limits, Bebco utilizes a combination of pulse-width modulation temperature control and snap-action safety switches, and listed by ETL for Class I, Division 2, Group A-D Hazardous Locations.

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 pressure increase.

API 500 Compliant Ventilation Systems
Bebco optional 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.

REFRIGERANT SERVICE PORTS – Provided with all Model WAC & WHP Units!
As a standard feature, all Bebco Model WAC & WHP Units feature high and low refrigerant system service ports! This feature allows service technicians to measure the amount of refrigerant and add it as needed to maintain proper operation over an extended lifespan!

REFRIGERANT PRESSURE SWITCHES – Provided with all Model WAC & WHP Units!
All Bebco Model WAC & WHP Units also feature high and low refrigerant pressure switches to monitor and control critical aspects of operation.This feature provides precise unit control and allows the Unit to detect and respond to any performance issues. Our advanced HMI and Digital Controllers can then also report these issue by on-screen and remote alarm system activation.

LOW AMBIENT CONTROLS – Provided with all Model WAC & WHP Units!

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.

Our exclusive process of isolating the evaporator and condenser coils, along with all refrigerant system tubing achieves a TOTAL coating in full accordance with coating manufacturer training and certification. This advance application method is unsurpassed in the industry and backed by our exceptional 5 Year Warranty!

Select any of our exceptional coatings to provide protection against mild, moderate or extremely corrosive environments, whether exposure duration is considered to be intermittent, prolonged or continuous.
