Custom Controllers



We make electronic circuit boards for custom industrial applications that are designed to fit the customer’s specific requirements. We develop application hardware and software as well as the mechanics, where needed.

Our extensive experience in the refrigeration and air conditioning market has led us to broaden our range of solutions to also include several touchscreen user interfaces, a set of BLDC and AC inverters for refrigeration compressors and a website for monitoring remote units.

From analyzing the customer’s needs and defining the specifics, not only do we take care of design, but we also manage every aspect of the product’s development including development and validation of prototypes, serial production, technical documentation and customer manuals.

We assist and guide our customers, and in many cases, become their electronic department throughout the entire life cycle of the product.


Chillers / Heat pump – Air Conditioning, UTA and Close Control – Blast Chilling / Blast Freezing- Temperature Controllers and Dry Coolers


Based on modern microcontrollers and fitted with applications developed in latest generation, high-level languages, Project Engineering products enable you to tackle even the most complex control issues.

Designing and developing purpose-built, custom controllers forms an integral part of the identity of Project Engineering, whilst the company’s years of experience in industrial electronics enables it to develop control boards with fast turnaround times and extremely competitive production costs.

We are able to ensure the quality of our product thanks to a certified quality system, meticulous design and validation stages, and thorough laboratory testing.

Another added value for the customer is being able to rely on the support of a group of expert technicians that are on hand to assist and are involved from as early as the prototype assembly stage, monitoring the product throughout its life cycle to ensure technical issues are resolved as quickly as possible and to adapt to the inevitably changing customer’s needs.



Flex is the new line of custom modular controllers with customized SW.
FLEX controllers feature a DIN-standard, compact case with a built-in bus. They come with a CPU module with high connectivity and a variable number of digital and analogue I/O modules.

The architecture is designed to easily and flexibly adapt the number of I/O to the type of application, reducing the number of connections.

If required, Project Engineering can customize the I/O modules and SW to optimise the cost and performance of the final solution.



Project Engineering has recently incorporated a new generation of touchscreen interfaces into its offering that are built around LINUX architecture.

For the OPERA product, currently the 5” and 7″ WVGA, 10.4″ SVGA and 10.1″ options are available, with resistant and capacitive touchscreens.

They are designed in both a panel mount version with IP65-rated protection and an open frame version.



Project Engineering has developed a family of inverters for BLDC (brushless) and AC motors, specially designed for refrigeration and air conditioning compressors.

As a manufacturer of OEM products, Project Engineering can develop the drivers and hardware to manage any type of compressor and is also able to customize the mechanical engineering.



Reach can monitor in real-time and allows ‘Onboard’ access to our customers’ equipment.

This web-based approach allows access to all platforms (Windows or Mac, including Android and iOS mobile devices) without the need to install any specific software on the device (or app, in the case of mobile devices).

Initially designed to interact with our boards, Reach can also connect to any MODBUS device.

This innovative tool is primarily intended for industrial machine manufacturers. Application examples include remote control of chillers, heat pumps, dry coolers, close controls and wine presses.

Thanks to our partnership with Vodafone, we can provide global connectivity (in every country in which Vodafone operates directly or with roaming agreements) in the event an internet connection via cable is not available.
