HVAC solutions from Acal BFi
Advanced technology solutions for air-conditioning and air-movement systems
HVAC solutions overview
In the 21st century we know that true air quality is about much more than dividing the acceptable from the unacceptable. Proper heating and ventilation are recognised as vital aspects of buildings where people can live and work in comfort, and be productive. Environmental legislation is being enforced to guarantee cleaner air that is free from toxins as well as ensuring improved system efficiency with new technologies such as heat recovery.
Acal BFi offer a variety of products and solutions suitable for 21st century air-conditioning systems.
At Acal BFi we understand the varied requirements from simple control loops in heat-recovery, air-conditioning systems, heat pumps, humidifiers / de-humidifiers and industrial air-conditioning systems to the more complex control systems where dust and CO2 measurements are made to control not only the temperature but also the air quality.
Our comprehensive solutions cover both component and system-level devices, which, combined with our experience of solving technical problems for key industry players, makes Acal BFi the ideal partner for your next design.
By utilising our expertise and innovative industry solutions our HVAC customers are able to reduce inventory, speed up production and improve product design and efficiency.

Sensing solutions for all HVAC / air conditioning applications
Acal BFi offer a wide range of sensors from world-leading suppliers suitable for HVAC / air conditioning applications.our sensor solutions
Featured product ranges
- Humidity sensors
Humidity sensors, widely used in heat-recovery HVAC systems, are a mainstay of Acal BFi sales in the heat-recovery market. Our product offer covers all technology types, enabling us to offer the optimum price / performance compromise. Accuracy ranges from ±1.7% to ±5.0%, and response times as quick as 1s. There are also dual-mode temperature and humidity sensors for applications where both parameters need to be measured using a single device.
- Temperature sensors
We have a wide range of NTC thermistors for measuring temperature. Our range covers all types of construction including epoxy and glass beads. We also package the thermistors to form bespoke rugged temperature probes.
- Board-mounted pressure sensors
Our range of PCB/board-mounted pressure sensors will find uses in small air-conditioning systems and blocked filter detection. We offer absolute, differential and gauge devices with multiple port configurations as well as pressure ratings with extended operating-temperature ranges (from -40°C to +125°C).
- Media-isolated pressure transducers
Historically our media-isolated pressure sensors have been used in systems moving large volumes of air. The range includes versions with and without temperature compensation with extended temperature ranges available.
- Airflow sensors
The Zephyr™ range of digital airflow sensors from Honeywell are available for airflow ranges as low as 10 SLPM (standard litres per minute) to as high as 300 SLPM with the industry’s smallest Total Error Band, fast response times and high accuracy. The product range is configurable and customisable with a wide choice of port styles aimed at simplifying design and reducing production complexity.
- Ultra small environment sensor
The Bosch BME280 is an ultra-small, single-sensor solution measuring ambient temperature, barometric pressure and humidity in a surface-mount LGA package measuring just 2.5mm x 2.5mm x 0.93mm.
- CO2 sensors
With CO2 sensors optimised for indoor air quality, energy conservation applications and demand control ventilation (DCV), Acal BFi have a range of solutions for monitoring CO2 concentration in air. The wide range incorporates ready-made transmitters and OEM units for those wanting to incorporate the technology into their own sensors.
- Dust / particle sensors
Increasingly particle detection is becoming part of the control loop in systems monitoring air quality. Acal BFi offer a range of OEM modules that detect the dust-particle concentration in air by using optical sensing techniques.
Technical support when you need it
In many instances off-the-shelf sensors are just not good enough for what you need. You may get the right sensing element, but then have to design a housing and cabling system to ensure correct in system functionality, or the assembly has certain drawbacks (such as the wrong connector or the probe is too long). Acal BFi can simplify the process by working with you to create a sensor assembly customised to meet your exact needs.
Use our extensive technical support and expertise to help guide you to the correct sensing element from our range, then work with our engineers to design the perfect housing and connector assembly, simplifying your production process and improving your ROI.
We have designed custom assemblies for remote temperature probes, humidity sensors and multi-axis accelerometers.
Interconnect solutions for domestic and industrial HVAC
Acal BFi have over 50 years of experience in specifying and supplying interconnect solutions.
