— The Symbol of BAPI Innovation
BAPI has earned a reputation as an industry leader by creating innovative and original solutions for common HVAC problems. The “Another Original BAPI” products on this page were designed, engineered and patented by BAPI.

WHAT'S NEW AT BAPI

The Redesigned BAPI-Stat 3 & BAPI-Stat 4 Sensors

   The BAPI-Stat 3 is a redesigned version of the original BAPI-Stat, which is a perfect temperature and humidity sensor for Operating Rooms, Clean Rooms and Elder Care Facilities.
   The BAPI-Stat 4 is a redesigned version of the BAPI-Stat 2, a powerful temperature or combination temp./humidity sensor with slider or pushbutton controls.


INDOOR ENVIRONMENT QUALITY (IEQ)


Demand Controlled Ventilation with Confidence!

 Most system designers use CO2 sensors to indicate room occupancy as part of their DCV setup. The problem with this method is that it ignores the offensive odors and VOCs that may be present even when the CO2 levels are low.

   BAPI's IEQ Sensor offers the best of both worlds. It measures all the contaminants in the air but outputs a signal that corresponds to the CO2 level, allowing system designers to use their existing DCV algorithms.

Available as VOC sensor alone or as a combination temperature sensor with optional setpoint, override and humidity.


Wireless Universal Input Transmitter

The Wireless Universal Input Transmitters take a hard-wired signal and transmit that signal wirelessly to a 418 MHz receiver. An Output Module connected to the Receiver converts the data back to its original form for the BAS controller.

The Analog Input version receives a 0-5VDC, 0-10VDC or 4-20mA signal, the Digital Input version receives any dry contact on/off status, while the Thermistor Temperature Input version takes a 10K-2 thermistor sensor input.


The "BAPI-Com" — Two-Wire Multifunction Sensor

Many existing buildings have two-wire sensors without the features that customers expect in today’s sophisticated systems. Rather than pulling new wires, the BAPI-Com sensor uses the existing two wires to provide a full function sensor with all the features.

Add Setpoint Adjustment, Occupant Override, LCD Display or %RH without Pulling New Wires


Refrigerant Leak Detector

The Refrigerant Leak Detector measures leaks and spills of R404A, R410A and/or R22. The sensor is temperature compensated for an accurate and reliable measurement.


   The green revolution is increasing the use of chilled beams and chilled ceilings in commercial buildings. The temperature of the chilled water has to be regulated above the space’s air dew point temperature or they will “sweat”, promoting mold growth and dropping water on the occupants and their belongings.

   BAPI’s Dew Point Sensor is an easy and economical way to measure the dew point temperature so that you can prevent the sweating.


BAPI Clean Cut
Cuts a perfect hole in the threaded ports
of the BAPI-Box and BAPI-Box 2 polycarbonate enclosures.

The Button Sensor

The Low Profile "Button" Sensor is ideal for locations where aesthetics are as important as the temperature measurement. The inconspicuous room sensor mounts easily by pushing through a 3/8" hole and secured with a peel off tape strip.


The original BAPI-Box and the new space-saving BAPI-Box 2 offer unprecedented ease of installation to save you time and money on every job. The two enclosures are waterproof with IP66 and NEMA 4 ratings. The hinged cover uses a single thumb latch for easy opening and access.

Pressure Sensing — As Easy As It Gets...

The “EZ Pressure” is the simplest sensor out there. The revolutionary mounting system allows for DIN rail, snaptrack or surface mounting. Plus, the three Outputs and 10 Pressure Ranges are field selectable by simply turning the rotary dial and pressing the button. It's also about 1/3rd the size of our standard sensor for easy panel mounting, and the four-digit display simplifies system troubleshooting.

Adaptor Plates for Retro Fit Room Units
BAPI Adaptor Plates cover wall imperfections when installing room sensors or thermostats. They are made in four different sizes and three different colors to match the new sensor. The Adaptor Plates can be painted or wall papered in place if desired.

No More Patching Holes in the Wall • 4 Styles and Colors Available


Wireless Thermobuffer Sensor for Coolers & Freezers
Transmits the temperature of walk-in freezers or coolers up to 100 feet to a receiver. The unit also helps prevents false alarms and compressor short cycling from opening and closing the door because it measures the temperature of the contents of the cooler or freezer, rather than the air temperature.

FPB - Flexible Probe Bracket

The FPB is used to mount averaging sensors, low limit thermostats, or liquid fill thermostats in duct applications for probe diameters from 1/8",1/4" and 3/8". The bracket is used to reverse the direction of the flexible probe with a smooth arc to eliminate the risk of kinking the sensor and damaging the probe.

Thermobuffer Temperature Sensor for Coolers & Freezers
The BAPI Thermobuffer Temperature Sensor eliminates the harmful short cycling and irritating alarms caused by opening and closing the door of walk-in coolers and freezers because it measures the temperature of the contents of the cooler or freezer, rather than the air temperature.

Field Selectable Differential Pressure Switch

The field-selectable Differential Pressure Switch is ideal for air filter monitoring, static pressure proving, airflow proving or auxiliary fan actuation. Because of its UL 353 listing, the switch can be used in safety circuits to protect heating appliances, heating systems, processessing systems and HVAC/R systems.

Wireless Room Units now Available with Temp. Setpoint & Override

BAPI's award-winning wireless room temperature transmitters and temperature/humidity transmitters are now available with temperature setpoint slider and/or occupant override pushbutton. BAPI's ever-expanding wireless solution received an AHR Expo Innovation Award Honorable Mention in 2007 and 2008.

Who Says a Sensor Has to Look Like a Sensor?

With the versatile BAPI Decora Style Sensor, executive offices and high end residences no longer need to sacrifice aesthetics for great control and comfort. The Decora sensor uses the same modern wall plate cover as the rest of the switches and outlets in the room, so it simply blends in. It is also mounted flush to the wall and is less obtrusive than a traditional sensor.

The BAPI-Guard Thermostat Protector

The BAPI-Guard prevents tampering, physical damage and unauthorized adjustment of thermostats. The attractive, low-profile design is available in two sizes to fit most thermostats. It is made of thick, durable polycarbonate and features exceptional airflow, key lock protection, horizontal or vertical mounting and easy installation with hardware included.

BAPI Commits to RoHS Compliance
BAPI has been working since early 2005 to remove environmentally harmful materials from our products and we support the European Union’s RoHS directive, which restricts the use of certain hazardous substances, such as lead and mercury. Even though many manufacturers of HVAC/R monitoring and control equipment are claiming exemption from RoHS compliance, BAPI is developing its new products and has revised current products to comply with the RoHS directive.

100 mA and 350 mA Voltage Converters
Joining BAPI's 75 mA voltage converter are two new models, a 100 mA and 350 mA version. All three voltage converters are a cost effective way of converting 24 VAC to 5, 15 or 24 VDC for use on peripheral devices that require DC voltage. All converters are very compact and designed to fit into standard 2.75" snaptrack.


The VC2700-STM -- 2.7 Amp Voltage Converter

The VC2700-STM is a 2.75" snaptrack-mountable 2.7 amp voltage converter. The unit takes a 24 VAC input and coverts it to a regulated and adjustable output of 3-24 VDC or a fixed output of 5 or 15 VDC.

The Fiber Optic Transceiver (FOX) Communication Kit provides all the functions for one fiber optic and remote RS-485 communications network, plus it comes in a self-contained, easy-to-apply and cost effective assembly.


RS-485 Repeater Communication Kit

RS-485 is the most common communications standard for DDC controllers; however, it is limited to 32 unit loads and 4,000 feet. Extending the network beyond this requires repeaters.
  The RS-485 Repeater Communication Kit provides all the functions for one repeater and remote RS-485 network, plus it comes in a self-contained, easy-to-apply and cost effective assembly.


Total Pressure Probe Assembly
  The Total Pressure Probe and Static Pressure Probe Assemblies connect to the BAPI Zone Pressure Sensor to provide duct static pressure or duct air velocity. The angled total probe faces into the airflow to sense the moving air’s total pressure while the static probe senses static pressure.


Electronic Technician Assistant (ETA)
  BAPI’s Electronic Technician Assistant (ETA) products are a uniform line of interface and communication devices that compliment a DDC installation. They consolidate many of the components being used at present and provide a more complete picture of the system than a laptop computer alone. The ETA line offers a number of benefits including simplifying the task of wiring and troubleshooting the system, cutting down on control panel clutter and providing additional feedback to the facilities manager and technician to keep the system performing at its optimum level.


Carbon Monoxide Sensor
BAPI’s Carbon Monoxide Sensor offers enhanced, long life electrochemical sensing with outstanding accuracy at low concentrations. The sensor has a range of 1-100 PPM or 1-300 PPM of CO with a resolution of 1 PPM and a linear output of 4-20 mA. The unit also features a robust enclosure and is available with or without LCD display.

Pushbutton Override with LED
