ACI has been a high quality manufacturer of sensors to the HVAC Industry since 1991. ACI has accumulated several State and industry related awards since their inception. Their company motto is “Engineering a Better Sensor Solution” and it the focal point of each department at ACI. This company-wide philosophy begins with their engineering department, and is followed all the way through to their sales and technical service departments. Invention and communication go hand in hand. Additionally, the technical service department has over 40 years of combined experience in the HVAC Industry. ACI takes great pride in their engineering achievements, investing substantially in new product developments, as well as existing product enhancements. We are confident in ACI’s engineering staff , as being one of the best in the Industry. ACI feels their products are only as strong as their weakest link. They prioritize a team approach in fulfilling a promise to their customers to “Engineer a Better Sensor Solution”. Value sets you apart from your competition. ACI’s company motto describes the commitment to provide value on many different levels. This is why Boston Aircontrols, Inc. has chosen ACI as their main HVAC controls product line.
The first product line ACI manufactured in 1991 was temperature sensors. This line has grown in scope every year since and has become a staple in the industry today. ACI goes the extra mile by double encapsulating and using high-quality etched teflon for probe-based sensors.
The ACI R2 offers the most stylish and modern room enclosure appearance in the industry today. ACI’s R2 provides great airflow which allows the enclosure to be fitted with numerous options and limits self-heating errors. Options include setpoint, override, and communication jack. This attractive enclosure can be ordered with your custom logo as well.
ACI’s standard plastic box has a hinged cover with a pressure latch closing mechanism, a mounting flange and a foam pad. Each sensing element is double encapsulated and is offered in numerous probe lengths. Ducts can also be ordered with a galvanized metal box, NEMA 3R, or NEMA 4X enclosure.
The ACI Outside Air Mount is based on a European style enclosure that locks out water with a gasketed cover and watertight fitting; and designed to be mounted flush to an exterior wall. A solar radiation/weather shield is offered when applications require additional protection from extreme weather conditions.
The ACI Immersion configuration incorporates the same high quality standards as the ACI Duct configuration but adds a ½ inch NPSM fitting in place of the mounting flange and includes a two part 304 stainless steel thermowell. This product comes standard with a galvanized box and can also be ordered with an optional plastic enclosure, NEMA 3R or NEMA 4X enclosure.
The ACI Strap-on comes with a sensor epoxied to the back side of a copper plate and with a foam pad, creates compression when the strap wormdrive is tightened. This creates a good thermal transfer around pipes 2” to 5” in diameter. Strap-ons come standard with a galvanized box and can be ordered with a plastic enclosure or a NEMA 4X enclosure.
ACI has several options for getting an average temperature reading. Our most common is the flexible copper tube type, which comes in lengths of 8’, 12’, and 24’. Copper is known to have an inhibiting effect on the growth of fungi’s and bacteria within the typical HVAC duct. Copper also has a thermal conductivity that is approximately 1.75 to 2 times higher than that of aluminum.
The ACI Button Sensor is designed to be aesthetically pleasing for higher profile applications. Due to the size and appearance of these products, any button sensor is a perfect choice for applications where room sensors want to remain un-noticed. Buttons are available in brass, stainless steel, and plastic for installation flexibility.
The ACI Stainless Plate has a sensor epoxied to its backside and is thermally shielded from temperatures inside the wall by an insulated foam pad. Options include an override and RS232 communication port.
A stainless steel probe encases a double encapsulated sensing element for durability and ease of installation. The wire leads are etched Teflon and are color coded to identify the sensing element involved. Additional types of wire and cable are available for probe related sensors.
ACI offers a full line of thermowells that cover a wide range of applications. A two-piece welded well comes standard with our thermowell sensor line. A machined well is available for moving water or high pressure applications. Also available are monel wells; which are well suited for marine and salt water applications.
Pressure accuracy and reliability is critical in the HVAC industry. ACI has refused to comprise in terms of design or calibration methods. Every ACI product is designed to exceed it’s listed specifications. This is evident in our pressure products.
Pitot Tube [3″]
The 3” PT is designed to sense the differential inlet pressure in the inlet section of VAV and Fan Terminal Boxes. Pitot Tubes can also be used to measure the differential pressure at any other location in the main or branch duct systems.
Pitot Tube [5.2″]
The 5.2” PT is designed to sense the differential inlet pressure in the inlet section of VAV and Fan Terminal Boxes. Pitot Tubes can also be used to measure the differential pressure at any other location in the main or branch duct systems.
